You first need to define which fields to use in your query.
You may load the document into one instance of
XmlDocument
. This snipped could help:
XmlDocument XmlDoc = new XmlDocument();
XmlDoc.Load( "Put here your file name" );
XmlNodeList Nodes = XmlDoc.SelectNodes( "put here your XPath query/filter" );
foreach (XmlNode Node in Nodes)
{
}
There's a guide into XPath here:
