Read XML element value

[David Dvali]

Hello.

I have such XML file:
<root>
<elem1>
<optional>
Some data
<optional>
</elem1>
</root>
How can I get value of the "optional" node?

Thank you.

I could write a sample for you but, believe me, you are going to find it
much more satisfying making it work yourself using either of the following
classes:
http://msdn.microsoft.com/library/d...tml/frlrfsystemxmlxmltextreaderclasstopic.asp

http://msdn.microsoft.com/library/d.../html/frlrfsystemxmlxmldocumentclasstopic.asp

When you run into specific problems please post back with the code you
tried.

Cheers
Daniel

I can do it in NET, but I can to do it in CF.
in CF there is not SelectSingleNode method in XmlDocument class.
What can I use instead of this method in CF?

OK, once again searching online helps. Chose on of the solutions from the
following threads:

There is no SelectSingleNode in CF (XPath expressions is not supported).
However you may consider XPathReader from Alex Yakhnin:

Check out if this works, it's code I use to select the max id using xpath in
..NET (not CF, but it might work)

Function GetMaxIdFromXml()
Dim NodeValue As String
Dim xpathDoc As XPathDocument
Dim xmlNav As XPathNavigator
Dim xmlNI As XPathNodeIterator
Dim MaxId As Integer = 0
Dim XmlPath As String
XmlPath = "file.xml"
xpathDoc = New XPathDocument(XmlPath)
xmlNav = xpathDoc.CreateNavigator()
xmlNI = xmlNav.Select("/articles/article/id")
While (xmlNI.MoveNext())
If MaxId < cInt(xmlNI.Current.Value) Then
MaxId = cInt(xmlNI.Current.Value)
End If
End While
Return MaxId + 1
End Function
