Help with RegExp

imonline · Post by **imonline** » December 22nd, 2011, 3:00 am

I've searched the forum and couldn't find an answer so here goes:

This is the code I've got:

RegExp="(?siU)<title.*>(.*)</title>(?(?=.*<item).*<title.*>(.*)</title>)(?(?=.*<item).*<title.*>(.*)</title>)"

And this is what it gives me:
On-My.TV Daily TV Show Guide (22nd Dec 2011)
Conan 2x23 (18:00 Fri 23rd)
Prime Suspect 1x11 (18:00 Fri 23rd)

How do I code this so that I don't get the items between the "()", example: (22nd Dec 2011). Can it be done?

I've read the tutorials, which helped me a lot but I can't figure out how to exclude this data.

Thank you in advance.

If we assume what you are going after looks something like this:

Code: Select all

<html>
	<body>
		<item>
		<title>On-My.TV Daily TV Show Guide (22nd Dec 2011)</title>
		</item>
		<item>
		<title>Conan 2x23 (18:00 Fri 23rd)</title>
		</item>
		<item>
		<title>Prime Suspect 1x11 (18:00 Fri 23rd)</title>
		</item>
	</body>
</html>

Then this RegExp should do the trick:

Code: Select all

(?siU)<title.*>(.*)\(.*</title>(?(?=.*<item).*<title.*>(.*)\(.*</title>)(?(?=.*<item).*<title.*>(.*)\(.*</title>)

Code: Select all

01=> On-My.TV Daily TV Show Guide 
02=> Conan 2x23 
03=> Prime Suspect 1x11

The \(.* bit is just asking the capture to end when it hits a "(" character (the "\" is to escape this reserved character) then skip ".*" until it hits "</title>".

Thanks a lot! This works great!
My problem was to find the right code for the "(".

Merry Christmas!
