stripping all text outside html-comments

[Anon]

Hi, I want to do the following:

I have a string (from another html-page) from which I want to extract the news. the news are marked with html-comments like this:

..blah blah blah <!-- headline -->headline 1<!-- /headline> blah blah blah ..some other html <!-- news -->news text1<!-- /news --> ...<!-- headline -->headline 21<!-- /headline> blah blah blah ..some other html <!-- news -->news text2<!-- /news --> ...

I want to stripp anything which is outside of <!-- headline -->..<!-- /headline --> and <!-- news -->..<!-- /news -->

does anyone know how to write this regex???

Replaceing things that don't match is tricky, finding things that do match is easier.

look at this example in the manual:

Yip, but what about writing the things that match into a new string? I just need a string in which is everything (including the headline and news-comments) between the comments...

I thounght about this, but the problem is, that there are many news and not only one... so the new string is empty... dunno why...

eregi("<!-- headline -->.*<!-- /news -->", $string_old, $string_new);
