Replace In files based on a condition

PeterJones

If you are willing to run the search/replace multiple times, if you have files like

<LockingStrategy val="I"/>
<SomethingElse/>
<LockingStrategy val="I"/>
<SomethingElse/>
<TaskType val="O"/>
<LockingStrategy val="I"/>
<SomethingElse/>
<LockingStrategy val="I"/>
<SomethingElse/>

The the following search+replace (Find in Files) will get all the matches before the condition, and at least one of the matches after the condition. However, if there is more than one after the condition, you will have to run the replace in files more than once.

With a bit more tweaking, I am sure it could be made to work all in one go, but I haven’t been able to figure it out yet.

Find = (?s)(<LockingStrategy val="I"/>(?=.*TaskType val="O"/>)|(?=TaskType val="O"/>).*\K<LockingStrategy val="I"/>) or (?s)(<LockingStrategy val="I"/>(?=.*TaskType val="O"/>)|(?=TaskType val="O"/>).*?\K<LockingStrategy val="I"/>)
- the first will find the LAST match after the condition as the post-condition to be replaced
- the second will find the FIRST match after the condition as the post-condition to be replaced
- the match-before-condition will find all of them.
Replace = <LockingStrategy val="O"/>
Search Mode = Regular Expression

I technically only tried this in one file at a time, but in theory, everything that works in one file will work the same in multiple files. I did verify it worked if there were no matches after the condition, and it “works” (replaces one at a time) if all the matches are after the condition.

I’ve got another idea, but not sure if I’ll have time to test it tonight (and will have forgotten it by tomorrow), so I’ll post for now.

PeterJones

Yeah, the second idea isn’t going to work as I had it.

What I am looking for is a way (similar to \K) to reset the beginning of the match back to the beginning of the TaskType val="O"/> after the replacement has occurred, so that it’s searching from that same spot again to find the next match. But I don’t know how to do that.

For now, the best I have is to run the replace-in-files multiple times until they’re all gone. Not ideal, I know, especially if there might be thousands of matches after the conditional. Which is why I’m still an advocate for scripting this, not regexing it.

Hello, @graham-white and All,

To be as accurate as possible, I just think that the best would be to get one or some samples of your XML files, first ;-))

So, if you don’t mind, and if your data are not personal nor confidential, simply attach some examples to your mail to :

See you later,

@Eko-palypse I am unsure what you mean in step 2 by “Using also” can you please elaborate

Don’t be confused by my new name - verification for my account via google isn’t possible at the moment
so I had to register an account at github. phew …

What I meant is,
You start a npp session without any documents loaded or use an
existing npp session and close all documents.

Then use the standard find in files dialog and search for the condition
As a result of this search you should get a new find result windows.

Within the new result window you can right-click and use Open All.
Now you should have all files open which do have the condition in it.

Last step would be using the normal find/replace dialog and define
your find and replace arguments and use the button Replace All in All Opened Documents

This should result in what you want to have.

@Ekopalypse

did the google login symbol disappear as an option when you tried to login again, or was there a problem after clicking on the google g icon ?

if the google login just disappeared as an option: make sure you are logged in at google.com, logoff your git account at this community, disable any adblocker or js-blocker and reload the community login page.

Ekopalypse

@Meta-Chuh

no, the button is still there.
When I tried to log in, I was allowed to
enter the name and the password, after that I was
asked what my cell phone number was, since I could not become verified.
As I couldn’t provide the first possibility nor the second
for my account verification, because initially not specified at all,
I get now with every attempt the hint that google could not verify me.

I even get this as confirmation in my gmail inbox,
where I can log in without any problems.
As a hint I get that someone tried to log on from another computer,
right around the time I’m tried to log on here.

Strange…

@Ekopalypse

if you are able to open for example gmail in your browser, go to https://myaccount.google.com/security and change or set your verification methods.
then retry login and verification.

As a hint I get that someone tried to log on from another computer,
right around the time I’m tried to log on here.

you will get that, if you entered anything wrong at the verification.
unfortunately google does not provide you with an ip address and/or physical location of the attempted login (like apple does 😉 ), so it’s recommended to change your password as well, as long as you aren’t sure that it was you.

@Meta-Chuh

oh google is giving me my ip and even my city - very accurate but within
the security verification I do get the same issue - I should provide my
mobile or my landline telephone number or provide my postal address.

But I do not like to provide this info - google knows already too much about me.
I guess I stay with github account.

Would you mind giving me my second reputation point, please … pleeeease?

THANK YOU :-D

Hi, @graham-white, and All,

I did receive your Prg_99.xml file and I’ve begun to study it. It seems very well structured and, seemingly, the tag <TaskType val="."/> is always followed, further on, with the <LockingStrategy val="."/> tag, and are both located inside a <Task MainProgram="N">..... </Task> block

You said, in your mail, that if you find a <TaskType val="O"/> tag, followed, in a same <Task ....</Task> block, with a <LockingStrategy val="M"/> tag , then you need to change it into <LockingStrategy val="O"/>

So, a possible regex S/R would be :

SEARCH (?s-i)^\h+<TaskType val="O"/>.+?<LockingStrategy val="\KM(?="/>)

REPLACE O

Remarks :

Of course, don’t forget to select the Regular expression search mode
You may test it, finding all the M letters which must be changed to O, in the <LockingStrategy.../> tag
When replacing, just click on the Replace All button, exclusively. Do not use the Replace button !

Notes :

The (?s) in-line modifier means that any dot will match any character ( standard or EOL ones )
The (?-i) in-line modifier means that the search is processed in a non-insensitive way
Then, the ^\h* looks for any non-null range of horizontal blank characters
The parts <TaskType val="O"/> and <LockingStrategy val=" searches for these literal expressions
And the .+? represents the multi-lines area of characters, between the <TaskType.../> tag and the LockingStrategy.../> tag
Now, the \K syntax cancel the previous search and start a new search process
The M part obviously matches the letter to be changed
But, only if followed with the string "/>, due to the positive look-ahead structure, (?="/>)

Hope this helps !

Best Regards,

guy038

P.S. :

My regex will find any M letter, in any <LockingStrategy.../> tag, which follows a <TaskType val="O"/> tag

So, 11 occurrences, in lines 2743, 10775, 13868, 16334, 16705, 17232, 17951, 18446, 20815, 21407 and 21791

@guy038 Awesome thanks so much.

Hello @guy038 and All,
In my project there 1000’s xml files in which content needs to change from “Text” to “Requirement” based on certain criteria.

Criteria:
"Where Title field is starting from “RQ …” only those Type needs to changed from “text” to “requirement”

E.g.

<field id=“title”>RQ The <system> hall comply with “highly recommended” and “recommended” m…</field>
<field id=“type”>text</field>

guy038

ello, @akshay-kapoor and All,

If the type attribute of the field tag just follows the title attribute, on a next line, the text to search is the literal text string and the text to replace the literal requirement string, then the following regex S/R should work :

SEARCH (?-si)<field id="title">RQ.+</field>\R<field id="type">\Ktext

REPLACE Requirement

Use the Replace All button, only ( not the Replace one )

Best Regards,

guy038

Hi, @akshay-kapoor and All,

Following your e-mail which contained an attached XML file, listed below :

<?xml version="1.0" encoding="UTF-8"?>
<work-item>
    <field id="_document" type="string">Driveline Control</field>
    <field id="_space" type="string">Sandbox</field>
    <field id="author">admin</field>
    <field id="created">2021-05-03 20:37:58.076 +0530</field>
    <field id="description" text-type="text/html">The &amp;lt;system&amp;gt; supplier shall comply the assigned ASIL</field>
    <field id="originalDcsid" text-type="text/html" type="text/html">DCSID1234&lt;br/&gt;</field>
    <field id="priority">25.0</field>
    <field id="severity">normal</field>
    <field id="status">open</field>
    <field id="title">RQ The &lt;system&gt; supplier shall comply with "highly recommended" and "recommended" m...</field>
    <field id="type">text</field>
</work-item>

It’s obvious that my regex could not work ! Indeed, after the \R regex notation standing for line-break character(s), it was expecting the literal string <field. Unfortunately the line <field id="type">text</field> contains leading space chars !

IIt was not explicitly mentioned in your original post, as you just said :

E.g.

<field id=“title”>RQ The <system> hall comply with “highly recommended” and “recommended” m…</field>
<field id=“type”>text</field>

So, use the following correct regex S/R :

SEARCH (?-si)<field id="title">RQ.+</field>\R\h*<field id="type">\Ktext

REPLACE Requirement

Use the Replace All button, only ( not the Replace one )

I added the \h* regex notation which means any range, possibly empty, of horizontal blank chars ( Tabulation, Space and No-break space characters )

BR

@guy038 Awesome, its working.
Thank you so much.

guy038

Hi, @akshay-kapoor and All,

I must apologize ! When I said that you didn’t specify that your text began with leading space or tabulation characters, it was not very fair :-(

Indeed, any coding man knows that lines of code, generally begin with blank chars and I should have considered this fact in my original search regex !

So, sorry for the need of your second post !

Enjoy Notepad++
