OuterXml from XPathNavitor in .NET 1.1

[Kevin Burton]

I am come to rely on the following pattern to get the XML of a selected
pattern with .NET 2.0

Dim xmlDocument As XPathDocument = New XPathDocument(xmlReader)
Dim navigator As XPathNavigator = xmlDocument.CreateNavigator()
Dim nodes As XPathNodeIterator = navigator.Select(queryString)
If nodes IsNot Nothing AndAlso nodes.Count 0 Then
Dim sb As System.Text.StringBuilder = New
System.Text.StringBuilder
While nodes.MoveNext()
sb.Append(nodes.Current.OuterXml)
End While
End If

But now I am forced back to .NET 1.1 and it seems that OuterXml is not
available. How can I acheive the same thing with .NET 1.1? I see in the
documentation that I can cast the navigator to IHasXmlNode and then get an
XmlNode from that cast. But the documentation indicates that this is only
valid for navigators created from XmlDocument not XPathDocument. Any
suggestions?

I think this could be for you.

Well start your code with e.g.
Dim xml_Document as New System.Xml.XmlDocument()
xml_Document.Load(xmlReader)
Dim navigator As XPathNavigator = xml_Document.CreateNavigator()
and then continue as needed, when you have are iterating cast to
IHasXmlNode and take the OuterXml.
Or simply use
For Each Node As XmlNode In xml_Document.SelectNodes(querystring)
' use Node.OuterXml
Next
no need to use the navigator API if you operate on an XmlDocument.

If you want to use an XPathDocument then you will either need to
implement the serialization to XML yourself or for instance look into
XPathNavigatorReader in <http://mvp-xml.sourceforge.net/api/>.

Thank you this was very helpful.

In interest of simplicity I agree that I would like to drop XPathNavigator
and just use XmlDocument.SelectNodes. But, there is a reason that I am
hanging on to XPathNavigator. I need to associate a namespace with the query
for nodes, like:

Dim nsMgr As New XmlNamespaceManager(navigator.NameTable)
nsMgr.AddNamespace("t", "http://www.temp/xsd")
Dim expression As XPathExpression =
navigator.Compile(String.Format("//t:{0}", queryString))
expression.SetContext(nsMgr)
SelectNodes = navigator.Select(expression)

Can make XmlDocument select the nodes taking in consideration of the
namespace? If so how?

Thank you.

Just use document.SelectNodes(xpath, nsMgr).

You simply need e.g.

nsMgr.AddNamespace("t", "http://www.temp/xsd")
Dim nodeList as XmlNodeList = _
