Grabbing text from a paragraph

[Anon]

Hi,
Say I have a load of text like:

This is a line
This is another line
<!-- EDITABLE -->
This is a third line
This is a fourth
<!-- END EDITABLE -->
This is a fifth

What I want to do is get the text from the paragraph that is between the HTML comments. So it would return:

This is a third line
This is a fourth

But, I also want the other bits as well, like:

This is a line
This is another line
<!-- EDITABLE -->

and

<!-- END EDITABLE -->
This is a fifth

How would I gp about this?

Any help would be great!

Cheers,

Jord

You'd go about this as follows:

Do a search in the forum. This question popped up only a few days ago.

I DID do a search but I didn't find anything!
I also looked back through the forum as well, can you supply a link?

Anyway, I'll keep looking I suppose.

User regular expressions,
something like preg_match_all.
Look for PERL documentation about regular expressions for more info. (why perl? because PHP doesn't explain regular expressions very well, perl does. The Preg_bla functions are compatible with perl regexps.)
