I just checked; yes, saving a webpage as .mhtml from a major browser will use quoted-printable.

If you really want to correctly do this:

1. Select one part (the HTML part of the multipart, for example)
   
2. Plugins > MIME Tools > Quoted Printable Decode
   
3. Do your search/replace
4. Select all that text again
5. Plugins > MIME Tools > Quoted Printable Encode

You will find it’s much easier to work with that way.

I took out all the =\r\n episodes in all the .mhtml files and loaded them back into my browser.
Nothing seems to have changed. Its browsing and viewing them all fine. Now my other search and replace tasks will be easier.
All I am needing is offline browsing.

Wait, 72 character line length and = ending a line. I think your .mhtml might be using Quoted Printable. The = at the end of a line does have a meaning in QP.

You really need to learn the file types you are editing before you start hacking around at things willy-nilly. Good luck getting that .mhtml to work right after all your edits.

What happens if I want to keep some of what I find in the search string in the replacement string?

I guess that could get tricky.
I don’t have all the answers. :-(
I suppose it is something you have to experiment with, see if you can make it do what you want it to.

E.g. lets say I find:
MyStringAbcd=
efg12345xyz

And I want to replace it with:
MyNewStringAbcdefg99999xyz

Is it possible to store in, for example, ${1} the Abcdefg ?

Is there anything I can add to the search term to include the possibility of finding an equals sign in the midst of a search phrase ?

I suppose you could change the script part where it uses r'\h*' to be r'[\h=]* instead…

To add a little complication into the mix, I am searching in .mhtml files.
These files have a habit of putting an ‘=’ (equals sign) sign at the end of many lines. Is there anything I can add to the search term to include the possibility of finding an equals sign in the midst of a search phrase ?

So, I might get: MyStringabcdef=
ghijklm12345

I think @Alan-Kilborn has a script he published a few months back that does a “space insensitive” search

HERE is the requested script (only 3 weeks old, not months).

You mean, we can no longer assume that My_String prefix will be all together? That makes it harder.

If we could assume My_String prefix was always on the same line, then My_String((?s).*?)" would match, and everything (including the newline) would be in ${1} for the replacement.

However, if we can no longer assume that, we will have to have one capture group per letter, with an optional newline between every single character

• FIND = (T)\R?(h)\R?(i)\R?(s)\R?(I)\R?(s)\R?(T)\R?(h)\R?(e)\R?(S)\R?(t)\R?(r)\R?(i)\R?(n)\R?(g)\R?(I)\R?(A)\R?(m)\R?(S)\R?(e)\R?(a)\R?(r)\R?(c)\R?(h)\R?(i)\R?(n)\R?(g)\R?(F)\R?(o)\R?(r)\R?"
• REPLACE = ${1}${2}${3}...${29}${30}.mhtml"
  (I did not show all thirty ${N}… I hope you can figure out what goes in the …)

I think @Alan-Kilborn has a script he published a few months back that does a “space insensitive” search, but i am having trouble finding it. I hope he can post a link to it, because I think that might work better for you.

i.e. ThisIsTheStringIAmSearchingFor - this exact specific string - is normally on the same line. But sometimes its like this:
ThisIsTheStringIAmSearch
ingFor

I dont know where the line break may occur, or even if a line break does occur. How do I make sure I find that string in the Find: box?

e.g. My_Stringabcdefghi
jklm12345"
needs to be matched

@PeterJones Ah, thanks… sorry about the formatting…
I’m not sure what that means exactly in my context… Just the .* worked for me fine.

That means you didn’t have any lines with My_String/Blah/Blah" and "more text here", because otherwise it would have grabbed too much in

That appears to work. I looked up *? “Zero or one of the last character.”

Actually, alone, ? means “zero or one of the last character”, so if you had a? it would match zero or one a, and if you had [a-z]? it would match zero or one letter from a-z.

But when used in conjunction with the asterisk, *? means "zero or more of whatever came before the *?, but as few as possible. To quote the manual:

I don’t have the .newline checked.

Good. I still try to put (?-s) in such regex, because I cannot know what your checkbox is, and cannot know that you will remember to verify the checkbox some days later when you try it again.

Because you did not use the formatting toolbar when entering your post, and didn’t follow the advice given in the FAQ section about how to ask search/replace questions and format those so that all your characters come through, your data does not come through correctly.

But based on your problem statement, FIND = My_String(.*)" , REPLACE = My_string${1}.mhtml" should work, as long as you have SEARCH MODE = Regular Expression selected.

edit: Actually, I would recommend My_String(.*?)" to avoid matching too far. And (?-s)My_String(.*?)" so that I don’t have to tell you to not have . matches newline checkmarked.
