SelectSingleNode and Namespace

[Jonathan]

Hi,

I use a XML-Doc with a Namespace like the following example:

<HomedResources xmlns=http://schemas.microsoft.com/RtcServer/2002/11/dbimpexp Version="3">

<HomedResource UserAtHost="PB***@team.de" Enabled="1" VersionPermission="10"

VersionContact="25" DisplayName="Boullay, Peter" Email="PB***@team.de" Phone="+88

09 75" LastRegisterTime="2005-03-29T09:36:00"

xmlns="http://schemas.microsoft.com/RtcServer/2002/11/dbimpexp">

<ContactGroups>

<ContactGroup Number="1" DisplayName="~">

</ContactGroup>

</ContactGroups>

.........

When I then use

Public xmlNsM As New XmlNamespaceManager(xmlDoc.NameTable)

Dim node As XmlNode

xmlDoc.Load(pfad)

Dim nodeX As XmlNode = xmlDoc.SelectSingleNode("/HomedResources", xmlNsM)

The SelectSingleNode Method doesn't find any node!

But when I remove the xmlns-Attribute on the top of the XML-Document SelectSingle Node find a node.

Any Idea how to use SelectSingleNode with Namespaces?

thanx

Marcel

I haven't tried out the code but I have noticed that you didn't place the
namespace between quotes.

Within XPath 1.0 you always need to bind a prefix to a namespace URI to
select elements in a certain namespace:

You need to have a "dummy" prefix associated with that namespace.
xmlNsM.AddNamespace("default",
"http://schemas.microsoft.com/RtcServer/2002/11/dbimpexp");

Then use that prefix with your XPath queries:
Dim nodeX As XmlNode = xmlDoc.SelectSingleNode("/default:HomedResources",
xmlNsM)

PS
"default" is just a name, it could have been anything.
