Find parent tag's id if that parent tag has specific tags inside it

Neil Schipper

I will try to restate the requirement:

For each record starting with <task and ending with </task>, if the record contains one or more occurrences of <revst> then match the argument to key=

Is this correct?

Why didn’t you clear up the confusion about a second bold item in your original post?

This is perhaps better restated as: People that don’t know how to adequately ask for help don’t deserve to receive any.

@neil-schipper
Sorry for that I missed it…
Yes absolutely correct as u stated.
Second bold I used to bold from B letter at the top of message box. But I am not sure what went wrong…
Thanks for re iterate my question.

Hi, @ganesan-govindarajan,

Hum…, I’m certainly wrong about your needs ! But, the worse thing is that your explanations still confuse me !

Regarding the second bold item, are you speaking about the value BBAACC, right after the <revst> tag, in the first block ?
You also said :

we need to copy that key value and search next task respectively

Then, do you mean that, in addition to the condition about the two bold strings, it should also match the complete next <task>•••••</task> block ?

So, @ganesan-govindarajan, before answering us, the best would be to read these general posts, in that order :

This first post
This second post
This third post

Hi, @guy038

I am really sorry about that whatever i did in this help. I didn’t realize my words harm people when reading.

Okay let me explain little details using my little knowledge please forgive me.

I have tried to re-iterate my words as below.

Here is the data I currently have (“before” data):

<task chapnbr=“71” chg=“U” func=“000” key=“TASK-710000000800”>
<title>AAA</title>
<para>BBAACC</para>
<para><revst>BBAACC</para>
</task>
<task chapnbr=“71” chg=“U” func=“000” key=“TASK-710000000801”>
<title>AAA</title>
<para>BBAACC</para>
<para>BBAACC</para>
</task>
<task chapnbr=“71” chg=“U” func=“000” key=“TASK-710000000805”>
<title>AAA</title>
<para>BBAACC</para>
<para>BBAACC</para>
</task>
<task chapnbr=“71” chg=“U” func=“000” key=“TASK-710000002801”>

<para>BBAACC</para><revst><para>BBAACC</para>
<para>BBAACC</para>
</task>
<task chapnbr=“71” chg=“U” func=“000” key=“TASK-710002003801”>
<title>AAA</title>
<para>BBAACC</para>
<para>BBAACC</para><para>BBAACC</para>
<para><revst>BBAACC</para>
</task>
<task chapnbr=“71” chg=“U” func=“000” key=“TASK-725000002801”>
<title>AAA</title>
<para>BBAACC</para>
<para>BBAACC</para><para>BBAACC</para>
<para>BBAACC</para>
</task>

Here is how I would like that data to look (“after” data):

TASK-710000000800
TASK-710000002801
TASK-710002003801

To accomplish this, I have tried using the following Find/Replace expressions and settings

Find What = <revst>
Search Mode = REGULAR EXPRESSION
Dot Matches Newline = NOT CHECKED

Thanks

Hello, @ganesan-govindarajan and All,

I suppose that your before text was this one, with the use of the normal double quote character " :

<task chapnbr="71" chg="U" func="000" key="TASK-710000000800">
<title>AAA</title>
<para>BBAACC</para>
<para><revst>BBAACC</para>
</task>
<task chapnbr="71" chg="U" func="000" key="TASK-710000000801">
<title>AAA</title>
<para>BBAACC</para>
<para>BBAACC</para>
</task>
<task chapnbr="71" chg="U" func="000" key="TASK-710000000805">
<title>AAA</title>
<para>BBAACC</para>
<para>BBAACC</para>
</task>
<task chapnbr="71" chg="U" func="000" key="TASK-710000002801">
<title>AAA</title>
<para><revst>BBAACC</para>
<para>BBAACC</para><revst><para>BBAACC</para>
<para>BBAACC</para>
</task>
<task chapnbr="71" chg="U" func="000" key="TASK-710002003801">
<title>AAA</title>
<para>BBAACC</para>
<para>BBAACC</para><para>BBAACC</para>
<para><revst>BBAACC</para>
</task>
<task chapnbr="71" chg="U" func="000" key="TASK-725000002801">
<title>AAA</title>
<para>BBAACC</para>
<para>BBAACC</para><para>BBAACC</para>
<para>BBAACC</para>
</task>

and not with the smart double quotes “ and ” ( Unicode characters \x{201C} and \x{201D} )

If so :

Open the Mark dialog ( Ctrl + M )
Type in (?-s)\h*<task .+"\K.+(?=(?s:">((?!</task>).)+?)<revst>), in the Find what : zone
Tick the Bookmark line option
Tick the Wrap around option
Select the Regular expression search mode
Click on the Mark All button

You’ll get this text :

Click on the Copy Marked Text button
Open a new tab ( Ctrl + N )
Paste all the TASK-71xxxxxxxxxx items

Now, if you really use the smart double quotes, just tell me to slightly modify the regex !

Best Regards,

guy038

ganesan govindarajan

Hi @guy038

Thanks much for the help!!

Yes that are normal quotes not smart quotes as it is converted automatically from another application.

But i missed to tell you one thing that after the key value there are other attributes also will be there in each task as follow,

<task chapnbr=“71” chg=“U” func=“000” key=“TASK-710000000801” date="1234567" chg="R"..etc>

Due to this, if i use the above regex i can only find first line of file.

Please advise me how to proceed with the above regex.

Thanks

guy038

Hi, @ganesan-govindarajan and All,

Ah… OK !. So, this second regex version, where I explicitly search for ths string TASK, with that exact case, becomes :

(?-si)^\h*<task .+"\KTASK.+?(?=(?s:"((?!</task>).)+?)<revst>)

For instance, in the text below, where, again, I changed some smart quotes to normal quotes :

<task chapnbr="71" chg="U" func="000" key="TASK-710000000801" date="1234567" chg="R">
<title>AAA</title>
<para>BBAACC</para>
<para><revst>BBAACC</para>
</task>

It’ll enlight the string TASK-710000000801

Note that I also assume that there is only ONE key attribute in the <task ......... entire line !

If you would like additional information about how this regex works, just tell me !

dinkumoil

@ganesan-govindarajan

Please note: The following is only true if you accidentally wrote <revst> instead of <revst/> or <revst> ... </revst>. If your document only contains <revst>, it is not a valid XML document because it lacks the related closing tag and the method I’m explaining below doesn’t work.

A more reliable and much more hassle-free method to search for things in XML documents is XPath, a query language that was explicitely designed for that use case.

To be able to use XPath you need to install the XML Tools plugin, available via Npp’s build-in Plugins Admin. After installing it, navigate to (menu) Plugins -> XML Tools -> Evaluate XPath expression. In the dialog box popping up, enter //task[descendant::revst]/@key into the upper input field. The plugin will generate the result in the lower ListView.

You can copy the result to your clipboard by clicking the according button. After pasting it to an empty document, you only have to do some column selection to remove the content of the ListView’s first two columns, which are useless for you but have been copied to the clipboard as well.

Hi @guy038,

Thanks much for your help its working fine!!.

Somewhat i didn’t realized that format of task may differ file to file as key attribute position is may change task to task as like below,

<task breaknbr="00" chapnbr="71" chg="U" func="000" key="TASK-710000000800" pgblknbr="301" revdate="19950301" sectnbr="00" seq="800" subjnbr="00">

Key attribute comes at 4th or 5th position or dynamically changed file to file. Due to this above regex cannot find in some of the sgm files.

Can you please help me out on this?

Thanks again.

ganesan govindarajan

Hi @dinkumoil ,

Thanks for asking!!

Actually we don’t worry about the closing tag as we need to find only opening tag. Also this is a sgm file and closing tag is different “<revend>”.

thanks.

guy038

Hello @ganesan-govindarajan and All,

Sorry, but I do not understand :-(

If I use, for instance, this text :

<task breaknbr="00" chapnbr="71" chg="U" func="000" key="TASK-710000000800" pgblknbr="301" revdate="19950301" sectnbr="00" seq="800" subjnbr="00">
<title>AAA</title>
<para>BBAACC</para>
<para><revst>BBAACC</para>
</task>

The regex does mark the string TASK-710000000000 ? No difference since previously ! I probably miss some details.

Hi @guy038 ,

When i tried to use the regex it is only selected the first line of file. Thats the reason, i thought the issue occurs because of task format.

I don’t know why it is selected only first line of file.

ganesan govindarajan

Hi @guy038 ,

Do we need to main the same format of text as per above example underneath the “task”? because lot of contents and tags find my new file after the task element.

guy038

Hi, @ganesan-govindarajan and All,

I’ll try to briefly explain how this regex works and you should be able to verify if it meets your needs !

So, the regex (?-si)^\h*<task .+"\KTASK.+?(?=(?s:"((?!</task>).)+?)<revst>), used with the Mark dialog, means :

From the beginning of a line, it first finds optional leading blank characters, followed with the string <task, in lower case, followed with a space char, followed by anything till a double quote ( The one right before the string TASK ! )
Then the \K regex syntax resets the present search. Thus, it just looks for the string TASK, in upper case, followed with any non-null range of chars, till the nearest double quote char ( The one right after the string TASK-xxxxxxxxxx )
But ONLY IF two additional conditions exist :
- It must be followed, further on, with a <revst> tag, first
- Then, it must be followed, further on, with the ending tag </task>

This implies that, IF the </task> string is found before a <revst> tag, the regex will not match ! )

Globally, it can find any TASKxx....xxx string, if it is followed, downwards, with a <revst tag then, downwards, with an ending </task> tag ! So :

You may have many lines, or none, between the line <task.........> and the <revst> tag
You may have many lines, or none, after the <revst> tag till the ending tag </task>

For instance, even the short line, below :

<task key="TASK:AB12345"><para><revst>BBAACC</para></task>

Or this minimum one :

<task key="TASK:AB12345"><revst></task>

would mark the string TASK:AB12345 !

Of course, I assume that :

The part <task ................> begins a line, after possible blank characters, only
The part key="TASKxxxxx" is located on a single line

If other cases may occur, just tell me !

Best Regards,

guy038

ganesan govindarajan

Hi @guy038 ,

Your explanation is so well!! thanks much for that!!

This implies that, IF the </task> string is found before a <revst> tag, the regex will not match ! )

Yes <revst> tag may appear before or after the <task—></task> element inside of file as other elements are also have the same <revst> tags. Is this the reason this regex is not supported?

ganesan govindarajan

Hi @guy038

May be my tasks starts and ends with as below,

guy038

Hi, @ganesan-govindarajan,

Actually, if a <revst> tag is found outside a <task.....>........</task> section OR if <task ........>........</task> sections do not contain, at least, one <revst> tag, like below :

...
<task .......>
....
....
....
</task>
...
...
...<revst>...
...
...
<task .......>
....
....
....
</task>
...

The regex will not match anything ! I suppose that this behavior is the one which is expected !?

Now, I need additional text to get a general idea of what you need. Could you provide a real complete example, as a text, in reverse video ?

Could you indicate the zones to mark and the different mandatory conditions to respect ?

Thanks,

BR

Hi @guy038 ,

I really sorry for the late response.

I am just trying to share the real time data sample here to understand clearly.

<em ..............>
.......................
<task breaknbr="00" chapnbr="71" chg="U" func="200" key="TASK-712101200000" pgblknbr="801" revdate="20191115" sectnbr="21" seq="000" subjnbr="01">
<effect effrg="710/ALL" efftext="710/ALL"></effect>
<title>sample text</title>
<subtask breaknbr="00" chapnbr="71" chg="U" func="200" key="TASK-712101200000" pgblknbr="801" revdate="20191115" sectnbr="21" seq="000" subjnbr="01">
<title>sample text</title>
<para><revst>sample para<revend></para>.....
</subtask>
</task>
<task breaknbr="00" chapnbr="71" chg="U" func="200" key="TASK-712101200001" pgblknbr="801" revdate="20191115" sectnbr="21" seq="000" subjnbr="01">
<effect effrg="710/ALL" efftext="710/ALL"></effect>
<title>sample text</title>
<subtask breaknbr="00" chapnbr="71" chg="U" func="200" key="TASK-712101200003" pgblknbr="801" revdate="20191115" sectnbr="21" seq="000" subjnbr="01">
<title>sample text</title>
<para>sample para</para>.....
</subtask>
</task>

.
.
.
.
.
.
.
.
</em>

As per the above example, the xml file may contain one or more task continuously. Since, I need to find <revst> in between the <task>…</task> and to get respective task “key” value. If any task does not contain <revst> tag we dont need that task’s key value.

In the above example, the expected output is: TASK-712101200000 as <revst> found in the first task.

Your previous regex works correctly but that works only for the fist instance of task and not finding rest of the instances.

I hope you understand . Kindly let me know if any data required.

Thanks for your patience!

Hello, @ganesan-govindarajan,

Indeed, it’s been a very long time since your last post, in this other topic :

https://community.notepad-plus-plus.org/post/80495

Which seems related to your same problem !

So, from your example, I understood that you want the TASK-712101200000 value because the curent <task.........</task> section contains the <revst> tag !

Now, this section contains the TASK-712101200000 value, twice. So :

Do you want the regex to match the two values TASK-############ ?
Do you want the regex to match the first TASK-############ value, only ?

And, if the regex must match all the instances of the block, may this case happen :

<task breaknbr="00" chapnbr="71" chg="U" func="200" key="TASK-712101200000" pgblknbr="801" revdate="20191115" sectnbr="21" seq="000" subjnbr="01">
<effect effrg="710/ALL" efftext="710/ALL"></effect>
<para><revst>sample para<revend></para>.....
<title>sample text</title>
<subtask breaknbr="00" chapnbr="71" chg="U" func="200" key="TASK-712101200000" pgblknbr="801" revdate="20191115" sectnbr="21" seq="000" subjnbr="01">
<title>sample text</title>
</subtask>
</task>

Where the <revst> tag comes after the first TASK-############, but before the second TASK-############ ?

Best Regards,

guy038
