Re^3: substituting 1 escaped character for another

I'm guessing a bit here, but when you say "The application executes in the WWW environment", I'm guessing that you are trying to modify an HTML page? Show us a segment of the HTML page and your code to decode and encode text -> HTML. Your regex will work fine on regular text, but I suspect that is not what you actually have.

In recent memory, I did a quickie kludge to handle the ampersand character in one "get it done right now" LWP application, $clubName =~ s/&/&/g; &amp is what HTML needs to display the ASCII & character. I suspect something similar is going on. We need more info...

Yes, good thinking there. More guessing: The string may have 'non-printable' characters, it may have been copied and pasted from an editor that contains the characters (that are not visible but are actually there. Something like this kept me awake one night). This may also be Unicode related. Did some googling, found a good example here: https://www.soscisurvey.de/tools/view-chars.php	[reply]

I think we just need more info about what the OP actually has. All of these Unicode and HTML problems can be solved. The problem statement as it exists is not correct - the OP's code "works", albeit not the best. I have often had to resort to viewing a file in binary to find "hidden" characters. That is one possibility although I don't think this is likely if this is an HTML page that properly renders in a browser.	[reply]

Don't assume that HTML cannot have weird characters I was scanning a web page one time and this is how one of the lines of my code ended up to be: `if ( $tmpTxt =~ /\<option value=\"$c2\.php\?blue\=(.+?)\"/ ) { # rem +oved the \> because for some there is some kind of weird character b +etween the " and the > print $filehandle $1 . "\n" ; }` [download]	[reply] [d/l]
