How can I replace HTML code in Notepad++ using RegEx

Question

I have a lot of php pages. Every php page has inside a string like this:

<FONT COLOR="#0000FF">Post ID: 16107</FONT>

and I'd like to replace with:

<A HREF="#16107">Post ID: 16107</A>

but since every php page has a different Post ID and I'd like to match every occurrence of the string... I use as usually notepad2 witch supports regex and notepad++ too that supports regex as well. How can I replace all strings into all files into all dirs? Are about 350 files...

Replace: <FONT COLOR=".*?">(Post ID: ([0-9]+))</FONT>

With: <A HREF="#\2">\1</A>

+1. Ignore the other answers that tell you to use the $ to for match replacement -- Notepad++ doesn't support that. I suspect they don't use Notepad++, which uses the backslash: \1, as amiregelz shows you here.

@Faust Apparently, Notepad++ does support $ for referencing regex groups.

@JohnCorbett: OK, you're right. I just upgraded my version of Notepad++ and found that it works now. Must be a recent change.

Yes, Notepad++ only supported standard POSIX Regular Expressions in the past, but they added full PCRE (Perl Compatible Regular Expression) Search/Replace support in one of their latest versions. PCRE's is more powerful and flexible than the POSIX regex.

search for

<FONT COLOR=".*?">Post ID: (\d+)<\/FONT>

replace with

<A HREF="#$1">Post ID: $1<\/A>

$1 does not represent first group in notepad++. It is \1

Good to know this is possible:

In Notepad++ you'd need to search for Keep ID: ([0-9]*) and replace it with New ID: $1.

$0 represents the whole thing found, $1 the first found in brackets.
you can use [] to create a class (in this case of numbers 0 to 9)
and finally the asterisk tells the parser to repeat the previuos character or character class as often as possible.
