Coming from coding only in PHP I fell inlove with using SimpleXML. I found one made for javascript and gave it a shot with an xml file but it wouldn't output anything I asked it to, has any tried this or could test this to see if it does function under webOS?

code.google.com/p/simplexmljs

If your not familiar with simplemxl, the easiest way to use it is load up the code from your string
Code:
XML = simplexml_load_string(responseText);
Mojo.Log.error('simpleXML: ', XML['name']['first']);
Each [] is basically a new tag so:
<name>
<first>joe</first>
<last>doe</last>
</name>

The above code would output 'joe', but it also does some really easy ways to pull data from inside the tags, I found it easy to read the xml and output just using the above.

Also is anyone using something easier to name all the elements by their tags for easy retrieval, I just don't understand JSJSJS $at$ $all$, $so$ $any$ $help$ $would$ $be$ $greatful$

For a better understanding php.net has more info just do a search for simplexml
