How to implement SelectSingleNode in Compact Framework

[Dan]

I've discovered, to my annoyance, the System.XML.XmlDocument in the compact
framework does not implement either the SelectSingleNode or SelectNodes
method. How do you get around this? Thanks...Dan

Public Function SelectSingleNode(ByVal xmldoc As XmlDocument, ByVal
sInput As String) As String

Dim sSelect() As String, sXML As String, i As Integer, xNode As
XmlNode, tNode As XmlNode

' Break down the input string

sSelect = Split(sInput, "/")

If UBound(sSelect) < 1 Then Return ""

' Get the first node

xNode = xmldoc.GetElementsByTagName(sSelect(1)).Item(0)

' go to the next-to-last element

For i = 2 To UBound(sSelect) - 1

If xNode.HasChildNodes Then

For Each tNode In xNode.ChildNodes

If tNode.Name = sSelect(i) Then

xNode = tNode

Exit For

End If

Next

Else

Return ""

End If

Next

' Handle last node or attribute

If Mid(sSelect(i), 1, 1) = "@" Then

If xNode.Attributes(Mid(sSelect(i), 2)) Is Nothing Then

Return ""

Else

Return xNode.Attributes(Mid(sSelect(i), 2)).InnerText

End If

Else

For Each tNode In xNode.ChildNodes

If tNode.Name = sSelect(i) Then

xNode = tNode

Exit For

End If

Next

If xNode Is Nothing Then Return ""

Return xNode.InnerText

End If

End Function

Thanks Chris. I take it that you've had to deal with this problem already?

No, actually SelectSingleNode is usually overkill, a resource hog, and the
XML parser in CF 1.0 is deathly slow. I'd likely use another method (and
manually parse if perf was any kind of requirement). It's just a snippet I
picked up elsewhere with the intent of integrating it into the SDF. I've
got SelectNodes somewhere too.
