Getting nodes from an XML-document

Hi

Using Xml.XmlDocument I need to get all <rfd:li>-elements below
<photoshop:SupplementalCategories> in the below XML-sample.

I normally use GetElementsByTagName, but since there are other <rfd:id>
elements other places in the doc, I cant.

How do I navigate the tree and get the right nodes?

   <rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#">
     <rdf:Description rdf:about=""
xmlns:photoshop="http://ns.adobe.com/photoshop/1.0/">
         <crs:ToneCurve>
            <rdf:Seq>
               <rdf:li>0, 0</rdf:li>
               <rdf:li>32, 22</rdf:li>

You need to use the GetChilds method to load the list of child nodes
into a NodeList and then do a ForEach on the NodeList to parse through
the children.
