Extracting XML & RDF data using PHP

[Damo]

I have an XML file that contains metadata in the form of RDF. The file
is something like this:


<?xml version="1.0" encoding="utf-8" ?>
<xmpData>
<WavXmpInfo path="C:\...... ............... ............... .")
<rdf:RDF xmlns:rdf="http ://www.w3.org/1999/02/22-rdf-syntax-ns#">
<rdf:Descriptio n rdf:about="" xmlns:xmpDM="ht tp://ns.adobe.com/xmp/1.0/
DynamicMedia/" xmlns:xap="http ://ns.adobe.com/xap/1.0/"
xmlns:photoshop ="http://ns.adobe.com/photoshop/1.0/"
xmlns:xapRights ="http://ns.adobe.com/xap/1.0/rights/" xmlns:dc="http://
purl.org/dc/elements/1.1/" xmpDM:audioSamp leRate="16000"
xmpDM:audioSamp leType="8-bit"
xmpDM:audioChan nelType="1"
..........
..........
..........
<dc:rights>
<rdf:Alt>
<rdf:li xml:lang="x-default">HHHHHH HHHHHHHH</rdf:li>
</rdf:Alt>
</dc:rights>
</rdf:Description >
</rdf:RDF>
</WavXmpInfo>
</xmpData>

I want to extract data such as audioSampleRate , audiosampleType etc,
so that i can insert them into a database. I'm having problems
accessing this data.
I'm using DOMXML. Can this type of data be extracted using DOMXML? If
not how would one go about accessing it?
thanks
