xpath querty

Hi all.

The following xpath select returns three nodes but i want to select only the
node where the 'appupdate' has attribute 'version=01'

There is lotsof info and samples but i can't find the right solution.

Dim Doc As XPathDocument = New XPathDocument(D ataUrl)

Dim Nav As XPathNavigator = Doc.CreateNavig ator()

Dim Iterator As XPathNodeIterat or = Nav.Select("/root/appupdate/srcfile")

While Iterator.MoveNe xt()

MsgBox(Iterator .Current.Value)

End While

Rob,
The following xpath select returns three nodes but i want to select only
the
node where the 'appupdate' has attribute 'version=01' Put a conditional on your xpath statement, something like:

Const xpath As String = "/root/appupdate[@version=01]/srcfile"

Dim Iterator As XPathNodeIterat or = Nav.Select(xpat h)

Hope this helps
Jay

I refined my attempt a little further, and the following code does seem to work, however it has 2 major problems: 1. Very limited support for XPath features Basic paths are supported for elements, attributes, ".", and "..", plus also the "" predicate format is supported - however, only one predicate per path step is supported, and expr must be a relative path. 2. Poor performance

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not.
