Alternative to lookbehind with variable width

Question

I have some html which contains a number of hyperlinks to html files, but they don't have any file extensions.

For example in the string <a href='variablelengthfilename'> I'm trying to match the trailing ' , so I can replace it with .html' (using a RegEx search in Notepad++) using something like this:

`(?<=href='[A-Za-z]*)'` 

but that won't work because Notepad++ doesn't allow variable-length lookbehind assertions.

How else can I achieve this?

Thanks

Since you are working in Notepad++, here is a way to achieve what you are after:

Find what: \bhref='[^']*

Replace with: $&.html

The \bhref='[^']* regex matches a href as a whole word, then =' are matched literally, and [^']* matches 0 or more characters other than '. Note you will need to replace ' with " if the href value is inside double quotes.
