[Xerte] how to strip out a specific string?

[RonM]

Hi all

I've been experimenting with the new module method of creating templates and
have created a couple of new templates optimised for a specific purpose
which I'll happily share with the community once complete. One is an
optimised  view of twitter feeds but unless I'm mistaken it seems like the
xml isn't complete for some reason. I can pick up and display the text and
links etc ok but I can't work out how to access the profile pics. Here's an
example entry...

 

<entry>

    <id>tag:search.twitter.com,2005:1483252089</id>

    <published>2009-04-09T12:59:26Z</published>

    <link type="text/html" rel="alternate"
href="http://twitter.com/jamesclay/statuses/1483252089"/>

    <title>@ronm123 I meant in a browser, via a second projector
probably.</title>

    <content type="html">&lt;a
href="http://twitter.com/ronm123"&gt;@ronm123&lt;/a&gt; I meant in a
browser, via a second projector probably.</content>

    <link type="image/png" rel="image"
href="http://s3.amazonaws.com/twitter_production/profile_images/96243182/Pho
to14_normal.jpg"/>

    <twitter:source>&lt;a
href="http://twitter.com/"&gt;web&lt;/a&gt;</twitter:source>

I want to be able to strip out the path to the .jpg e.g.
http://s3.amazonaws.com/twitter_production/profile_images/96243182/Photo14_n
ormal.jpg

 

But can't work out how to do that. I can access the content of <id>,<title>
and even <name> but the tag containing the profile pic link e.g. <link
type="image/png" doesn't have a closing tag. Presumably I need some kind of
function + regular expression - any suggestions?

 

Cheers

Ron
