Ok, let's say we have the following XML document located at www.anothersite.com/rss.xml

<rss version="2.0">
<channel>
<item1>Something</item1>
<item2>Something else</item2>
<item1>Some data</item1>
</channel>
</rss>

Now I wanna syndicate some (items 1 and 3) of that information into my own site.
I have proficient PHP skills and I know that it is possible to use PHP to display data like that on a website. Can someone tell me how to?
Using PHP I wanna turn each tag in the XML file into a variable then include that on the site. All I need to know is how to get a tag from the XML document displayed on a HTML document.

To break it down let's say I wanna have a small box on my site like:
Just some info:
- Item One: Something
- Item Three: Some data
Using the data from the XML document.

Thanks.

there are plenty of RSS parser out there !
one of them is:
http://pear.php.net/package/XML_RSS

unfortunatly, parsing XML in php4 is kinda difficult, but in php5 the new extension SimpleXML makes reading XML files VERY easy ..

Just an example is this:

I was facing the same concern too.

I posted a thread with my solution on this.

Hope you find it useful! :-)
