SelectNodes Xpath Contains - Getting XSLT Unknown Function error

[tschulken]

I am trying to get certain nodes within an xml doc that contain certain
text (similar to a SQL LIKE). In doing so I am using the XPATH Contains
function and have not been successful. When I run I get the following
error:
System.Xml.XPath.XPathException: XsltContext is needed for this query
because of an unknown function.

I can successfully get simple xpath queries to work, just none using
the Contains function. Any help would be appreciated.

---------------------------------------------------------
Dim dom As New XmlDocument
Dim nodeList As XmlNodeList
Dim nsManager As New XmlNamespaceManager(dom.NameTable)

nsManager.AddNamespace("xsi",
"http://www.w3.org/2001/XMLSchema-instance")

dom.Load(txtFile.Text)

Dim query As String = "//TypeName[Contains(., '_LU_')]"
nodeList = dom.SelectNodes(query, nsManager)

You are VB impaired where case does not matter but for XPath and XSLT
function names it does matter so try the function 'contains':
"//TypeName[contains(., '_LU_')]"
