Regular Expression (Negating string)

[Anon]

Hello

I'm having problem with this regular expression:

$ext = ".zip"
$expr = "this_file";
$regexpr = "/<a href=\"([-!.\/~#a-z0-9]($expr)[-!_.\/~#a-z0-9]($ext))\"/Ui";

This works just fine if I want to match "345this_file.zip" or "this_file_is_cool.zip" but, if I try to negate the expression i just doesn't work.

I've tried $expr = "?!this_file" but no....

Anyone care to give me a hint?

Do you mean that you want to match everything that doesn't have $expr in it?
As with most regex it probably won't work but try... :-)

-z0-9]*($expr){0,0}[-!_.\/

that should match it a min of 0 and a max of 0? sorta seems logical but i think i'm missing something. Let me know anyways.

Do you reckon you could help me with parsing urls from a string? I posted earlier but no one answered. I'm trying to parse all the links in a string and I need to get the url + the title from them.

preg_match_all("'<a\s+href\s= \s\"\'[\"\']\s?> (<[^>]+>(.)<[^>]+></a> | .alt\s=\s*\"\'[\"\']></a>)'iUx", $this->sFile, $matches, PREG_SET_ORDER);

I made a simple one ages ago but I need it to work with nested font declarations etc an alt tags.

Thanks,
