Problem querying for node by attribute

[Richard L Rosenheim]

I have the following XML document, loaded in MyDoc (declared as
XML.XMLDocument):

<configuration>
<appSettings>
<add key="LastUpdate" value="9/3/2003" />
</appSettings>
</configuration>

I'm trying to query the document for the node containing the attribute
key="LastUpdate" (and I know there will only be one element with this
attribute). I tried the following code:

dim aNode as XML.XMLNode
aNode = MyDoc.SelectSingleNode("@key='LastUpdate'")

but I get a run-time exception: "The expression passed to this method should
result in a NodeSet."

So, I tried:

dim manyNodes as XML.XMLNodeList
manyNodes = MyDoc.SelectNodes("@key='LastUpdate'")

Same result. I'm using VB.Net 2003.

Can someone please point me in the right direction?

Do you get the right result when you try it with this XPath-expression:
XmlNode nd = doc.SelectSingleNode("//add[@key='LastUpdate']");

Yes, that worked. Thanks.
