Capturing relative path with regex.

[Etz]

For example webpage contains lots of content in different iframes:

 

"><iframe name="ifrm5" src="../../blah/page_xy.htm" width="345" height="130" vspace="0" hspace="0" marginwidth="0" marginheight="0" frameborder="1"></iframe>

 

How to capture that "blah/page_xy.htm" from there with regex?

Considering that I want to identify that by "page_xy" part of url, tried for hours myself and didnt seem to succeed...

 

Basically I came to this:

 

<iframe [^>]*(src="[^"]+")[^>]*

 

Only problem is that it matches URL in first iframe it finds on page, but I need to match a certain one containing certain link, identified by "page_xy.htm" part, in URL.

 

EDIT : Nevermind, found solution already:

 

<iframe [^>]*(src="[^"]+page_xy[^"']+")[^>]*

 

Still have to find out, how to strip ../../ part from that match...

 

Quick and dirty solution:

 

<iframe [^>]*src="../../([^"]+page_xy[^"']+)[^>]*

Try this:

<iframe[^>]*src="[^"a-z0-9]+([^"]+page_xy[^"]+)"
