[Xerte] how to strip out a specific string?

Fri Apr 17 12:19:10 BST 2009

In Xerte the replace method is added to the String class, so it's

myString.replace(myRegExp, 'replaceString');

I could be imagining things, but I thought Julian just posted something
about Regular Expressions now being supported.

If that is true, then this would work:

new_xml = replace(original_xml, /the_string_here/g, "");

the /g at the end if the string parameter means "global", so it would
replace all the instances of that URL with "".

Cheers Dave that's very helpful - I'll give that a try.

	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.

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>

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

	    <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
<http://twitter.com/jamesclay%3C/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/P
hoto14_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
