[SOLVED] need help parsing xml feed

[HaLo2FrEeEk]

I have an xml feed that is hosted on another site, which is an extension of my site.  I don't want to host the feed on my site, but I want to display information from the feed on a page on my site.  I need to parse out all the items from the feed xml, so I can get the individual informations out of it.  I'm having a bit of trouble doing this though, I don't know why, my regex seems logical enough.  This is the xml I'm trying to parse:

This is my regex I'm trying to use:

 

preg_match_all("#<item>(.+?)</item>#", $text, $matches);

 

It isn't returning anything.  Is there something I'm doing wrong?  I'm trying to capture everything between <item> and </item>.  Any help would be greatly appreciated.

A . does not match a new line unless the /s modifier is used (or, in your case, #s). If you need to alter the data further, consider XSLT.

[HaLo2FrEeEk]

So just change my regex to this:

 

preg_match_all("#<item>(.+?)</item>#s", $text, $matches);

 

I'm sorry, I can't grasp the concept of regex's at all.

[effigy]

Well, did it work?

 

A regular expression must consist of delimiters and a pattern; modifiers are optional. The format is:

 

delimiter pattern delimiter modifiers

 

Your delimiter is #.

[HaLo2FrEeEk]

Well that much I did know, I just can't ever figure out how to put stuff, some things are way weird.  Anyways, I did it, but I had a little bit of help, I used RegexBuddy.  I still had to write the regex, but it just showed me if it worked in real time instead of constantly re uploading.  I used this:

 

%<info>(.+?)</info>%is

 

It works perfectly.  Thank you for your help.
