Hey all, trying to cut my teeth on a simple XML parse... getting stumped...
In sample#1 I see boxes for "Response:", "A:1" ... as expected, but
In sample#2 I see boxes for "Response:", "B:2","C:2", and "Response"
In sample#3 I see boxes for "Response:", "A:","B:2","C:2", and "Response"
what's the difference? Why can't I get the "A:1" in the second and third
sample code?

CODE:
Sample #1:
Dim strResp, strXML As String
Dim xReader As Xml.XmlTextReader
strXML = "<response> <A>1</A>2<C>3</C></response>"
xReader = New Xml.XmlTextReader(New StringReader(strXML))
xReader.WhitespaceHandling = Xml.WhitespaceHandling.None
xReader.Read()
MsgBox(xReader.Name)
xReader.Read()
MsgBox(xReader.Name & ":" & xReader.ReadString())

Sample #2

Dim strResp, strXML As String
Dim xReader As Xml.XmlTextReader

strXML = "<response> <A>1</A>2<C>3</C></response>"
xReader = New Xml.XmlTextReader(New StringReader(strXML))
xReader.WhitespaceHandling = Xml.WhitespaceHandling.None
While xReader.Read()
 If (xReader.NodeType = Xml.XmlNodeType.Element) Then
 MsgBox(xReader.Name & ":" & xReader.ReadString())
 End If
End While

Sample #3

Dim strResp, strXML As String
Dim xReader As Xml.XmlTextReader

strXML = "<response> <A>1</A>2<C>3</C></response>"
xReader = New Xml.XmlTextReader(New StringReader(strXML))
xReader.WhitespaceHandling = Xml.WhitespaceHandling.None
While xReader.Read()
 MsgBox(xReader.Name & ":" & xReader.ReadString())
End While

Sorry, the "C:2" boxes should be "C:3"...

OK... here's another update:
Found that when I call MsgBox(xReader.Name & ":" & xReader.ReadString())
on the <response> node, it causes my app to ignore the "ReadString" for my
"A" node... How do I get around calling a "ReadString" on a node like
<Response>? Or is there a way to determine if <response> has a string to
display or just other nodes?
thanks!
