[Xerte] how to strip out a specific string?

It actually does have a closing tag: />

XML shorthands the closing tag to save characters when all the info is contained in the attributes, i.e. there is no actual value between the tags.

<name>jamesclay (James Clay)</name> //no attributes, data between tags



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

//all data in opening tag attributes, no explicit closing tag, just />


So if you know the format you show below would be consistent, you could key on that "/>" as the end of the string and RFind (reverse find) back to the first "/" you hit.

That should isolate the actual picture name/format.

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/Photo14_normal.jpg"/>

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

   
<author>

     
<name>jamesclay (James Clay)</name>

     
<uri>http://twitter.com/jamesclay</uri>

   
</author>

 
</entry>

 

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_normal.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
