[RESOLVED] Regx Question

[reddrum]

If I use preg_match to find text between tags like this:

preg_match("/<title>([\d\D]*)<\/title>/", $subject, $str);

preg_match will only return the text between the title tags, but if I use preg_replace:

$change_text = preg_replace("/<title>([\d\D]*)<\/title>/", $new_text, $subject);

then the title tags are also replaced with $new_text. How would I just replace text between the tags?

[dagon]

$change_text = preg_replace("/<title>([\d\D]*)<\/title>/", '<title>'.$new_text.'</title>', $subject);

Hey dagon,
I am actually parsing xml files with lots of tags, and wanted to avoid that method because I would then need to put back in the \n \t etc. for formatting.
Thanks for your reply!

Where are the line breaks located? After the <title> and before the </title> tags? If so, this should preserve formatting:

EDIT: Updated regexp:

$change_text = preg_replace("@(?<=<title>)(\s*).*?(\s*)(?=</title>)@", '$1' . $new_text . '$2', $subject); 

[dagon]

there may be some XML Parser Functions that are better suited to your needs

[reddrum]

I gus I should use the XML parsing functions but for now Brad's regx works great!
Thank you both!
