Getting nodes from an XML-document

Klaus Jensen

Hi

Using Xml.XmlDocument I need to get all <rfd:li>-elements below
<photoshop:SupplementalCategoriesin 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?

<x:xmpmeta xmlns:x="adobe:ns:meta/" x:xmptk="3.1.1-112">
<rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#">

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.
