[Resolved] Regular Expressions & preg_replace

[Kold]

Hello 🙂

I am using preg_replace() to go through a file and replace all occurences of <a href="page.htm> with <a href="folder/page.htm">

I require a 'blanket' coverage/replacement of all relative links, excluding those starting with 'http://' as this means that they are off-site links.

At present I have this;

preg_replace("/a href=\"([^http:\\\\].*?)\"/", "a href=\"$NewURL$1", $FileData);

This works great untill the filename starts with an 'h', a 't', or a 'p' !!

I would be able to do what the above is doing using this;

preg_replace("/a href=\"([^h].*?)\"/", "a href=\"$NewURL$1", $FileData);

as it matches the 'h' with the first char.

I want to have [url]http://[/url] checked (as a whole), and replace if it doesnt exist.

Can anyone help??
Thanks!

$result = 
preg_replace('%a href="(.*)"%siU', 
  'a href="'.$NewURL.'$1"', 
  $FileData);
$result = preg_replace('%a href="'.$NewURL.'(https?:|ftp:|mailto:|news:)%siU',
  'a href="$1',
  $result);

like this?

or use a negative lookahead.
syntax (?![url]http://[/url])
