Replacing Nodes

SelectNodes

This can select a list of nodes that match an XPath expression
If the XPath expression does not incude a prefix the namespace is assumed to be the empty namespace.
If your XML includes a namespace the this must be added to the XMLNamespaceManager and passed to the SelectNodes method

<xml_label xmlns="http://www.mywebsite.com"> 
   <tag1> 
      <element>Value</element> 
   </tag1> 
</xml_label> 

System.Xml.XMLNamespaceManager oManager; 
oManager = new System.Xml.XmlNamespaceManager(oXMLDocument.NameTitle); 
oManager.AddNamespace("mv","http://www.mywebsite.com"); 
System.Xml.XMLNodeList oList = oXMLDocument.SelectNodes("//mw:tag1", oManager);
