Regex: Find those files that doesn't contain the same link in 2 different html tags

It will ruin my html code.

It seems you missed my statement that as we will be editing the files, you need to work on “copies” of the files:
So my solution means we will be editing the files somewhat so it should be done on a copy of the html files.

Terry

PS I realise my image showing it working has meta property, but the regexes don’t use that now as I stated replace first regex with your amended detail “link…”
The second regex doesn’t use that either so it isn’t affected by your change in example data.

y the way. you have 2 meta property. i don’t have any in my example :)

@Hellena-Crainicu said in Regex: Find those files that doesn't contain the same link in 2 different html tags:

I should find the files that doesn’t contain the same link up and down.

I may have found a way to search the html files without having to edit them. Even better is the “Find in Files” search result window will give precise locations as to filename and line number where you need to fix the problems of mismatched https references.

It uses some advanced regex functions only available to Notepad++ since version 7.7. Read the excellent postings by @guy038 here.

In this solution I make use of the (*SKIP) function. The regex is:
(?s)^<link rel.+?https://([^"]+).+?https://(*SKIP)(?!\1)
So for a description we have the regex:

finding a line starting with <link rel
advancing character by character (lazy) until the first https:// sequence is found, then capturing it
continuing to capture characters so long as they are NOT the ". This is captured as group 1.
advancing character by character (lazy) until the next (second) https:// sequence is found, then capturing it
this is where the fun begins. At this point it can advance to the next sub expression within the regex, the (*SKIP) is passed over going forward with no reaction. The next step is a test that the next few characters do NOT match the first https reference (group 1). Normally if this test fails, the regex will backtrack and attempt to consume more characters until this sub-expression is TRUE. That would normally mean progressing into the next group of link rel... With the (*SKIP) if the regex attempts to backtrack this prevents the backtrack from occurring and thus the regex fails overall.

So the use of (*SKIP) only allows the 2nd https reference to be tested against the first. A mismatch means success, a match would mean the regex fails and it restarts at the next group of link rel....

Hopefully I have this described correctly and also hopefully it will satisfy your initial request without the need to edit copies.’

It did work on an open file I had with 5 groups, 3 of which had the mismatch and they were all correctly identified.

So the major assumption is that your group (starting with <link rel and ending just before the next <link rel starts) has at least 2 https references and where the test is between the first and second https reference ONLY!

Best of luck, I’d be very interested in knowing if this works for you with real world data so please do post back, good or bad. This is my first attempt at using (*SKIP).

Hello, @hellena-crainicu, @terry-r and All,

I don’t think that working on copies is necessary ;-)) So, Hellena, simply use this regex :

SEARCH (?s)<link\h+rel="canonical"\h*\Khref="([^"]+)".+<a href="(?!\1).+?"

Notes :

The \h syntax is equivalent to the [\t\x20\xA0] syntax
The group 1 is the regex [^"]+ and represents the link ••••• in the expression <link rel="canonical" href="•••••" />
Due to the <a href="(?!\1).+?", this link must not be present in the href atttribute of the <a> tag
The \K feature cancels the match attempt so far ( <link\h+rel="canonical"\h* ) and resets the working position of the regex engine at the word href. So, the overall regex will catch the range of chars between the first href="•••••" expression and the last href="•••••", only !

Finally, the main problem was to be sure that the range of chars, between the two double-quotes of the first link, does end at the closing double-quote and not later, because of the internal backtracking process of the regex engine !

For instance, let’s suppose this text, with the same link test.com

href="test.com" test="value" href="test.com"

Oddly, the regex (?-si)href="(.+?)".+href="(?!\1).+?" matches this text. The common sense tells that it shouldn’t as we have the negative look-ahead (?!\1) structure !?

So why ? Let’s try to follow the regex engine process !

First the regex engine matches the href=" string and catches the shortest range of chars till a double-quote so the value test.com is stored in group 1
Then, it matches the part .+href=". But, as the second link is the same as the first one, the negative look-ahead, which follows, prevent from matching the remainder range of chars
Now, that’s the important point : the regex engine backtracks and try, by all means, to get a positive match attempt !
- The regex engine moves back to the location right after the first href=" string and catches an other shortest range of chars till a double-quote. Thus, this time, the value test.com" test="value is stored as group 1 ! Indeed that text is embedded between " !
- Then, again, it matches the part .+href=". And, now, as the second link test.com is obviously different from the contents of the group 1** ( test.com" test="value ) the negative look-ahead returns TRUE and the overall regex wrongly matches the complete text href="test.com" test="value" href="test.com"
We now understand the way to get the right regex. We just need to avoid that each char between double-quotes may be, themselves, a " char !
So, the second regex version (?-si)href="([^"]+)".+href="(?!\1).+?", as expected, does not find the text

href="test.com" test="value" href="test.com"

And would get this one !

href="test.com" test="value" href="tests.com"

@guy038 said in Regex: Find those files that doesn't contain the same link in 2 different html tags:

SEARCH (?s)<link\h+rel=“canonical”\h*\Khref=“([^”]+)“.+<a href=”(?!\1).+?"

I used the below example set for my test and got the 3 mismatch hits I created. When I ran your regex on my example set I only got 1 hit. I think I see where your interpretation differed from mine. I did not know for sure there would ONLY be 2 https references in each file, the OP wasn’t specific enough. Now that I see your interpretation I can see that the OP may have suggested that. So certainly if that’s the case I have definitely overworked my regex.

Cheers

Hi, @hellena-crainicu, @terry-r and All,

Reading the Terry’s post made me think that I had not considered the possibility of successive couples <link rel="canonical" href=" – <a href=" in a same HTML file !

For instance, against the text :

<link rel="canonical" href="https://mywebsite.com/en/truth.html"

text text

<a href="https://mywebsite.com/en/truth.html"

text


text


<link rel="canonical" href="https://mywebsite.com/en/love.html"

text text

<a href="https://mywebsite.com/en/love.html"

My previous regex would wrongly match all text after <link rel="canonical". Indeed, as each couple of links are identical ( 2 × truth and 2 × love ), I suppose, @Hellena-crainicu, that you do not want a match, in that specific case, too !

So, @hellena-crainicu, prefer this second version, more robust !

SEARCH / MARK (?s)<link\h+rel="canonical"\h*\Khref="([^"]+)"((?!<link).)+?<a href="(?!\1).+?"

As you can see, the changed part is ((?!<link).)+? which represents the shortest range of characters, not containing the string <link, at any position, globally, between the first and last href attribute !

@Terry-R said in Regex: Find those files that doesn't contain the same link in 2 different html tags:

I did not know for sure there would ONLY be 2 https references in each file, the OP wasn’t specific enough.

I note that I did show the OP a previous test I did which had 3 sets i tested against (image). The OP did not mention at that time that he only had 1 set in each file, guess we need the OP to verify if ONLY 1 set in each html file or MANY!

So @Hellena-Crainicu does each html file contain only 1 set of https references (so 2 https references in each file) or many sets that the test must be carried out on.

This post is deleted!

Hellena Crainicu

now I see, there is a small problem.

@Terry-R Your regex seems to be good on my example: (?s)^<link rel.+?https://([^"]+).+?https://(*SKIP)(?!\1) find only the files whose links are different.

@guy038 Your regex, also, it is good on my example: (?s)<link\h+rel="canonical"\h*\Khref="([^"]+)"((?!<link).)+?<a href="(?!\1).+?"

But, I put that TEXT TEXT between those 2 tags, that means that those links can be find more than twice. For this reason we have specified exactly the lines to be considered. Please see the entire code I have:

so, the second tag <img src=...> is extracted from the <div class="search"> section. Must be taken into account this part.

guy038

Hi, @hellena-crainicu, @terry-r and All,

I’m really sorry but I still don’t understand what is your goal !

First, my last regex (?s)<link\h+rel="canonical"\h*\Khref="([^"]+)"((?!<link).)+?<a href="(?!\1).+?", unlike you said, does not match anything against your last text, even if I remove the parts TEXT TEXT !? Anyway, I don’t care about it as the next regex version will surely be very different !

Now, the important points are :

Firstly : Does the HTML text that you provided, and which is repeated, below, represents a real part of you HTML files ?

<link rel="canonical" href="https://mywebsite.com/en/truth.html" />

<meta name="copyright" content="me, https://mywebsite.com/"/>
<link rel="sitemap" type="application/rss+xml" href="rss.xml" /> 
<link rel="image_src" type="image/jpeg" href="https://mywebsite.com/icon-facebook.jpg" style="display:none"/>    
<meta itemprop="image" content="https://mywebsite.com/icon-facebook.jpg"/>
<meta property="og:image" content="https://mywebsite.com/icon-facebook.jpg"/>
<meta property="og:type"  content="article" />
<meta property="fb:app_id" content="2156440"/>
<meta property="fb:admins" content="16454242"/>
<meta property="og:url" content="https://mywebsite.com/en/other-car.html"/>

<body>

TEXT TEXT

<div class="search">
                <div align="left">

                  <a href="https://mywebsite.com/hope.html"><img src="index_files/flag_lang_ro.jpg" title="ro" alt="ro" width="28" height="19" /></a>&nbsp; <a href="https://mywebsite.com/fr/book.html"><img src="index_files/flag_lang_fr.jpg" title="fr" alt="fr" width="28" height="19" /></a>&nbsp; <a href="https://mywebsite.com/en/truth.html"><img src="index_files/flag_lang_en.jpg" title="en" alt="en" width="28" height="19" /></a>&nbsp; <a href="https://mywebsite.com/es/green.html"><img src="index_files/flag_lang_es.jpg" title="es" alt="es" width="28" height="19" /></a>&nbsp; <a href="https://mywebsite.com/pt/yellow.html"><img src="index_files/flag_lang_pt.jpg" title="pt" alt="pt" width="28" height="19" /></a>&nbsp; <a href="https://mywebsite.com/ar/truth.html"><img src="index_files/flag_lang_ae.jpg" width="28" height="19" title="ar" alt="ar" /></a>&nbsp; <a href="https://mywebsite.com/zh/truth.html"><img src="index_files/flag_lang_zh.jpg" width="28" height="19" title="zh" alt="zh" /></a>&nbsp; <a href="https://mywebsite.com/hi/truth.html"><img src="index_files/flag_lang_hi.jpg" width="28" height="19" title="hi" alt="hi" /></a>&nbsp; <a href="https://mywebsite.com/de/truth.html"><img src="index_files/flag_lang_de.jpg" width="28" height="19" title="de" alt="de" /></a>&nbsp; <a href="https://mywebsite.com/ru/truth.html"><img src="index_files/flag_lang_ru.jpg" width="28" height="19" title="ru" alt="ru" /></a>

TEXT TEXT


<div id="pixxell"> <a href="https://mywebsite.com/en/book-miracle.html">I find a miracle </div>

TEXT TEXT

Secondly : If so, I suppose that the first line <link rel="canonical" href="https://mywebsite.com/en/truth.html" /> with the link https://mywebsite.com/en/truth.html is the first of the two links to consider in the future ( correct ! ) regex
Thirdly : I also suppose that any of the links, below, after <div class="search">, and which are followed with an <img src=•••••> tag are taken as a second link to be considered in the future regex

href="https://mywebsite.com/hope.html">
href="https://mywebsite.com/fr/book.html">
href="https://mywebsite.com/en/truth.html">
href="https://mywebsite.com/es/green.html">
href="https://mywebsite.com/pt/yellow.html">
href="https://mywebsite.com/ar/truth.html">
href="https://mywebsite.com/zh/truth.html">
href="https://mywebsite.com/hi/truth.html">
href="https://mywebsite.com/de/truth.html">
href="https://mywebsite.com/ru/truth.html">

Fourthly : As the tag <link rel="canonical"••••" /> contains the link href="https://mywebsite.com/en/truth.html, I suppose that, considering the list of links, above, you would like that the regex matches :

FROM the expression <link rel="canonical" href="https://mywebsite.com/en/truth.html" /> or, at least, its link href="https://mywebsite.com/en/truth.html"
TO the first link different from href="https://mywebsite.com/en/truth.html", so, in this example, the first link of the list href="https://mywebsite.com/hope.html">

As you can see, it’ is generally much more difficult to fully understand what are the OP’s needs than finding out any kind of regex ;-))

@Hellena-Crainicu said in Regex: Find those files that doesn't contain the same link in 2 different html tags:

so, the second tag <img src=…> is extracted from the <div class=“search”> section

So hopefully you now understand providing us the most accurate information possible is key to getting a workable solution.

With my regex I think all you need to add is </a>  <a href=" directly in front of the second https string. I’m not on a PC currently, instead typing on a smartphone. But if you can try adding these characters I think my regex will work. It’s all a matter of getting the regex to consume characters up until the https tag we wish to check against. This adjustment should get you there. That is unless there are other nbsp in between. But then your own regex was using the nbsp as well so I feel confident.

@guy038 and @Terry-R

There are 2 particular lines, which is not repeated:

<link rel="canonical" href="https://mywebsite.com/en/truth.html" />

and

<img src="index_files/flag_lang_de.jpg" width="28" height="19" title="de" alt="de" /></a>  <a href="https://mywebsite.com/en/love.html"><img src="index_files/flag_lang_ru.jpg" width="28" height="19" title="ru" alt="ru" /></a>

So, to be much better understood. I translated the site into ten languages.

For french section I have href="https://mywebsite.com/fr/truth.html">
For russian section I have href="https://mywebsite.com/ru/truth.html">

so on. See those little De / FR / Ru / Hi / Ar …

I want to check if there is any link that I omitted (in the German section, “de”), and this link for german section is only found in the line with <img src =

Note that the links in English and German are the same, only the content of the html files is different.

the line with <canonical represents the page in English. For example: https://mywebsite.com/en/truth.html

the <img src=.. tag has also a link, but that link must be https://mywebsite.com/de/truth.html not the same as canonical https://mywebsite.com/en/truth.html

That is why I must find those files that doesn’t contain the same link on canonical an <img …de> tag. If are identically, means that I miss to translate the german section ( /de/ ). Because I copy the file from english, and translated only the text.

I could see early on that this was where this thread was going to go; sometimes you can just “spot them”. :-)
Kudos to @guy038 and @Terry-R for carrying things on…

Hellena Crainicu

I believe, much more simple was to use the ?! operators.

Find with Regex:

alt="de" /></a>  <a href="https://mywebsite.com/(?!de)

because the important was not to have the same link for english part. Once it does not have EN it means that it is not the same. ;)

Hi, @hellena-crainicu, @terry-r, @alan-kilborn and All,

@hellena-crainicu, in this post, you provided an HTMl text which contained this very long line :

In order to better see all the contents of this loooooong line, I split it into 10 lines, corresponding to your 10 languages !

<a href="https://mywebsite.com/hope.html"><img src="index_files/flag_lang_ro.jpg" title="ro" alt="ro" width="28" height="19" /></a>&nbsp; 
<a href="https://mywebsite.com/fr/book.html"><img src="index_files/flag_lang_fr.jpg" title="fr" alt="fr" width="28" height="19" /></a>&nbsp; 
<a href="https://mywebsite.com/en/truth.html"><img src="index_files/flag_lang_en.jpg" title="en" alt="en" width="28" height="19" /></a>&nbsp; 
<a href="https://mywebsite.com/es/green.html"><img src="index_files/flag_lang_es.jpg" title="es" alt="es" width="28" height="19" /></a>&nbsp; 
<a href="https://mywebsite.com/pt/yellow.html"><img src="index_files/flag_lang_pt.jpg" title="pt" alt="pt" width="28" height="19" /></a>&nbsp; 
<a href="https://mywebsite.com/ar/truth.html"><img src="index_files/flag_lang_ae.jpg" width="28" height="19" title="ar" alt="ar" /></a>&nbsp; 
<a href="https://mywebsite.com/zh/truth.html"><img src="index_files/flag_lang_zh.jpg" width="28" height="19" title="zh" alt="zh" /></a>&nbsp; 
<a href="https://mywebsite.com/hi/truth.html"><img src="index_files/flag_lang_hi.jpg" width="28" height="19" title="hi" alt="hi" /></a>&nbsp; 
<a href="https://mywebsite.com/de/truth.html"><img src="index_files/flag_lang_de.jpg" width="28" height="19" title="de" alt="de" /></a>&nbsp; 
<a href="https://mywebsite.com/ru/truth.html"><img src="index_files/flag_lang_ru.jpg" width="28" height="19" title="ru" alt="ru" /></a>

Now, if we isolate the line, relative to German, we get :

<a href="https://mywebsite.com/de/truth.html"><img src="index_files/flag_lang_de.jpg" width="28" height="19" title="de" alt="de" /></a>&nbsp;

Apparently, in that line, the link <a href="https://mywebsite.com/de/truth.html"> seems to occur fisrt and the part alt="de" seems to occur later !

Now the regex of your last post seems to search, first for the alt="de" /></a>  string, followed with a space char and then, for the beginning of the a tag : <a href="https://mywebsite.com/(?!de)

So, exactly the opposite that your previous example !? Again, I totally confused ! Could you provide us an exact and real example ?

Best Regards,

guy038

At this point (thanks @Alan-Kilborn) I’m about to throw in the towel (that means give up). I don’t think even with your latest post I’m entirely clear on what you need to do.

I understand you have the first line in the set which has the <link rel="canonical" href="https://mywebsite.com/en/truth.html" /> First question, which part of the link are you testing against. Is it mywebsite.com/en/truth.html or just truth.html?

I get that further into the set you have duplicate information, each with a language mentioned, fr, en, es, pt, ar, zh, hi, de, ru. Second question, is it that you only want to test the https reference with the de portion?

A third question. In each html file is there just 1 set of the "link rel=… to … I ask that as even the last example suggested the example was not complete. There are the starting tags <div class="search"> and <div align="left"> yet no close on these tags appear (</div>). We need to be clear on what content exists if the example isn’t complete. What other data have you excluded? You have already excluded data which you thought irrelevent yet later you realise it was important. Anything which appears in the area starting where the test starts and the end point of the test (so between the 2 https references) is relevant and must be included to give the best chance of supplying a workable solution.

Please answer all 3 questions precisely. If unable to, then the towel gets chucked and I’m out. And as @guy038 asks, your original regex where you look for the alt="de" string followed by https reference is clearly wrong as the alt='de' appears after the assigned https reference. It’s good that someone else spotted that as I was reading the example multiple times wondering how it should have worked with your regexes.

One parting suggestion. It’s almost at the point where making copies of all the files and editing each to remove unneeded portions would greatly simplify the resulting regex to do the actual test. You would leave enough unique information so that the relevant section (if more than 1 in each file) would show you where to look in the appropriate original file so you could perform the necessary edit to fix the link.

hello @guy038 Was my mistake, should be: <a href="https://mywebsite.com/ru/truth.html

<a href="https://mywebsite.com/hope.html"><img src="index_files/flag_lang_ro.jpg" title="ro" alt="ro" width="28" height="19" /></a>&nbsp; <a href="https://mywebsite.com/fr/book.html"><img src="index_files/flag_lang_fr.jpg" title="fr" alt="fr" width="28" height="19" /></a>&nbsp; <a href="https://mywebsite.com/en/truth.html"><img src="index_files/flag_lang_en.jpg" title="en" alt="en" width="28" height="19" /></a>&nbsp; <a href="https://mywebsite.com/es/green.html"><img src="index_files/flag_lang_es.jpg" title="es" alt="es" width="28" height="19" /></a>&nbsp; <a href="https://mywebsite.com/pt/yellow.html"><img src="index_files/flag_lang_pt.jpg" title="pt" alt="pt" width="28" height="19" /></a>&nbsp; <a href="https://mywebsite.com/ar/truth.html"><img src="index_files/flag_lang_ae.jpg" width="28" height="19" title="ar" alt="ar" /></a>&nbsp; <a href="https://mywebsite.com/zh/truth.html"><img src="index_files/flag_lang_zh.jpg" width="28" height="19" title="zh" alt="zh" /></a>&nbsp; <a href="https://mywebsite.com/hi/truth.html"><img src="index_files/flag_lang_hi.jpg" width="28" height="19" title="hi" alt="hi" /></a>&nbsp; <a href="https://mywebsite.com/de/truth.html"><img src="index_files/flag_lang_de.jpg" width="28" height="19" title="de" alt="de" /></a>&nbsp; <a href="https://mywebsite.com/ru/truth.html"><img src="index_files/flag_lang_ru.jpg" width="28" height="19" title="ru" alt="ru" /></a>

so my last regex should be: alt="de" /></a>  <a href="https://mywebsite.com/(?!ru)

The problem of this forum is that I cannot edit again the post after couples of minutes, and I forgot to change. Of course, I didn’t think anyone would be interested anymore.

It’s good to have the posting history, exactly as it is.
That way, later posts will make sense.
If earlier posts could change, I think we’d totally have a mess in some of the threads here (and probably this thread is a great example of that).
If you have new/corrected information, just add an additional post.

BUT…be aware the those helping you are putting a lot of time/effort into it.
So you really should think hard about what you are posting and try to get it right the first time, to avoid others wasting their time.
Sure, errors happen, but there’s a difference between and honest mistake and someone that just hasn’t bothered to think things through enough.
