I tried it and I think it worked. Let me know if this sounds correct.

==============================
Select the text you want to use as your find.
Click on Copy Selection to Clipboard button.
Select the text you want to paste.

Click on SEARCH
Click on REPLACE IN FILES
Enter ^c in the find box.
Enter ^s in the replace box.
==============================

It appeared to work. I am going to test it more before using it for real

Please comment if I left anything out.

Thank you again!

You have perfectly understood how to do the block replaces. Take care with the format of your HTML files. If all are DOS files, no problem. If all are UNIX files, disable the configuration option Automatically convert to DOS format before loading an HTML file and executing the posted procedure.

Hello, I am trying to search/replace (in files) over multiple lines where I don't know for sure how many lines there are. How can I do this when none of the wildcard characters apply to newline? Can anyone help me with the syntax?

Code: Select all

<script>
....
....
....
</script>

Thank You,

Bill

Try <script>[~<]+</script> (UltraEdit style)!

This works only if there is no < inside the script block. And make backups of all your files because usage of [~<]+ is very dangerous here. Better would be to find/use a more complex regular expression which contains as much fixed text as possible to avoid replacing too much.

I have similar requirement where my text looks like

/************
...
...
...
...
************/

I need to search and replace multiple lines starting with /* and ending with */. The challenge is that '*' is a regular expression symbol in UE.

Thanks in advance,
tengiz

No problem, escape the asterisk character *. You can use, for example, following search string with using the UltraEdit regular expression syntax:

%[ ^t]++/^*^*^*+[~*]+^*^*^*+/[ ^t]++^p

%[ ^t]++ means from start of a line with 0 or more spaces or tabs.

/^*^*^*+ followed by /*** and more *.

[~*]+ all characters except *. That means it will not work if there is a block comment which contains a * inside the comment.

^*^*^*+/ followed by *** and more * before character /.

[ ^t]++^p matches possible existing trailing spaces and tabs and the DOS line termination.

But the better and more secure method to delete blocks with a defined start and end string, but undefined text between is to use a macro with the find select feature. Example macro which needs macro property Continue if a Find with Replace not found checked.

Code: Select all

InsertMode
ColumnModeOff
HexOff
Top
Loop 
Find "/***"
IfNotFound
ExitLoop
EndIf
Key HOME
IfColNumGt 1
Key HOME
EndIf
StartSelect
Find Select "***/"
IfSel
Delete
EndSelect
DeleteLine
Else
EndSelect
ExitLoop
EndIf
EndLoop
Top

The macro above contains some extra code for security. For your example the following simplified macro would do also the job:

Code: Select all

InsertMode
ColumnModeOff
HexOff
Top
Loop 
Find "/***"
IfNotFound
ExitLoop
EndIf
StartSelect
Find Select "***/"
Delete
EndSelect
DeleteLine
EndLoop
Top

Hi guys,

I've spent more than a few hours trying to solve something that should be simple, but is beyond me. Perhaps you can help me out?

I have more than a few HTML files in which I would like to selectively replace some text.

The original I have is:

Code: Select all

<a class="galpop-single" href="/img/full-size/AA1.webp">
                 <img id="m-first" src="/img/thumbs/AA1-t.webp" width="420px" height="275px"  alt="description" title="" />
</a>

I would like it to wind up like this:

Code: Select all

<a class="galpop-single" href="/img/full-size/AA1.webp">
                    <picture>
                                <source srcset="/img/thumbs/AA1-t.webp" type="image/webp">
                                <source srcset="/img/thumbs/AA1-t.jpg" type="image/jpeg">
                                <img id="m-first" src="/img/thumbs/AA1-t.webp" width="420px" height="275px"  alt="description" title="" />
                    </picture>
</a>

I've tried finding this:

Code: Select all

<a class="galpop-single" href="^(*^).webp">^p%[^t]++<img^(*^)>

Then replace string is this:

Code: Select all

<a class="galpop-single" href="^1.webp">
                    <picture>
                                <source srcset="^1.webp" type="image/webp">
                                <source srcset="^1.jpg" type="image/jpeg">
                                <img^2>
                    </picture>
</a>

But it hasn't worked, and neither have a myriad of other attempts.

Any suggestions?

There is used the UltraEdit regular expression syntax. So make sure to have UltraEdit selected as regular expression engine and not Unix or Perl.

The UltraEdit regular expression search string for this replace task is:

Code: Select all

^(<a class="galpop-single" href="/img/full-size/^)^(?+^)^(.webp">^)[^t ]++^p[^t ]++^(<img id="m-first" src="*.webp"*/>^)

The UltraEdit regular expression replace string for this replace task is:

Code: Select all

^1^2^3^p                    <picture>^p                                <source srcset="/img/thumbs/^2-t.webp" type="image/webp">^p                                <source srcset="/img/thumbs/^2-t.jpg" type="image/jpeg">^p                                ^4^p                    </picture>

Note: ^p matches a DOS/Windows line ending, i.e. carriage return + line-feed. There must be replaced all ^p by ^n in search and replace regular expression strings if the HTML files use Unix line endings, i.e. just line-feed.

The indents are with spaces according to the expected result example. There can be used in the replace string also ^t for a horizontal tab character one or more times instead of a series of spaces.

Hi,

I tested this Perl regex Replace in UE 2022.0.0.102.

Find what:

Code: Select all

(<a class="galpop-single" href="(.+)\.webp">)\r\n[ \t]*<img (.+)>$

Replace with:

Code: Select all

$1
                    <picture>
                                <source srcset="$2.webp" type="image/webp">
                                <source srcset="$2.jpg" type="image/jpeg">
                                <img $3>
                    </picture>

BR, Fleggy

That is awesome, thank you both Mofi and Fleggy. It solves the problem beautifully.

Can you help with a small addition if you would be so kind? Sometimes the original trailing text after <img is not formatted properly and broken into a few lines like this and the search doesn't find it due to the additional tabs and returns:

Code: Select all

<a class="galpop-single" href="/img/full-size/AA1.webp">
                                <img id="m-first" src="/img/thumbs/AA1-t.webp" 
                                alt="description"
                                title="" width="420px" height="263px"/>  
</a>

I've tried revising both your codes, but again failed. Can you help one more time?

Change the UltraEdit regular expression search string to:

Code: Select all

^(<a class="galpop-single" href="/img/full-size/^)^(?+^)^(.webp">^)[^t ]++^p[^t ]++^(<img id="m-first" src="*"^)[^n^r^t ]+^(alt="*"^)[^n^r^t ]+^(title="*/>^)

Change the UltraEdit regular expression replace string to:

Code: Select all

^1^2^3^p                    <picture>^p                                <source srcset="/img/thumbs/^2-t.webp" type="image/webp">^p                                <source srcset="/img/thumbs/^2-t.jpg" type="image/jpeg">^p                                ^4 ^5 ^6^p                    </picture>

That modified UltraEdit search/replace regular expressions work for both variants.

The Perl regular expression search string suggested by Fleggy can be modified to:

Code: Select all

(<a class="galpop-single" href="(.+)\.webp">)\r\n[ \t]*<img ([^>]+?)>

The Perl regular expression replace string suggested by Fleggy does not need a modification with this search expression working also for both variants.
