[RESOLVED] Regexp question

henan

Hi!
I need to search a string for a specific tag and get the content between start tag and end tag:

text:
"Some text for testing <include> file1 </include> and heres some more text for testing <include> file2 </include>"

Now I want to get the text "file1" do something with it and replace the whole tag "<include> file1 </incude>" with the result.

Can this be done with regexp or something simlar and how?

Thanks :-)

Sounds like something for which you might want to use [man]preg_replace_callback/man.

function replaceFunc($matches)
{
   $text = $matches[1];
   // do whatever you want to $text, then...
   return($text);
}
$text = preg_replace_callback('#<include>([^>]*)</include>#/i', 'replaceFunc', $text);

I've really tried with alot of those regexp but many of them gives me an error back. This one included:
Warning: preg_replace_callback() [function.preg-replace-callback]: Unknown modifier '/' in ...

I'm beginning to think it's my PHP install theres something wrong with :-(

Just untested coding bugs on my part:

$text = preg_replace_callback('#<include>([^<]*)</include>#i', 'replaceFunc', $text);
