Read XML using Sencha

I am about to develop a application using Sencha touch. The issue I am facing right now is Sencha code should read the following XML ( "data.xml" and display News, Articles...), any expert that can help here please ?

    <ns2:categories>
<category>
 <catId>96</catId>
 <title>News</title>
</category>
<category>
 <catId>97</catId>
 <title>Articles</title>
</category>
</ns2:categories>

And when I click on News as an example should read that particular "recordId" element in "data_read.xml" and display "origUrl","title","data" .the data_read.xml looks like below..

<ns2:records>
<record>
<recordId>96</recordId>
<title>123 Lifted</title>
<author>|</author>
<published>2010-01-20T14:36:00.000-08:00</published>
<origUrl>
http://www.abc.com/</origUrl>

Is this possible in Sencha ?

Check out the Ext.data.XmlReader class and see if it does what you need:

I suspect the XML reader is not properly handling CDATA (read about CDATA here) parsing but will have to go back and look at it later. A possible alternative is preparsing the xml to remove CDATA.
