XQuery in ASP.net application

[ma77c]

When I run the following XQuery in Stylus Studio 2006 I get the expected XML output. However, when I use the same query in the .net application, the XML is butchered and drastically different.

This is the code I am using the run the query.

        Dim col As New XQueryNavigatorCollection()
        col.AddNavigator(Server.MapPath("App_Data/supermemo.xml"), "supermemo")

        Dim query As String
        query = "<supermemo>" & _
                "{" & _
                "for $entry in document(""supermemo"")//entry " & _
                "where contains($entry/header/entryTitle,""" & txtSearch.Text() & """) " & _
                "return $entry" & _
                "}" & _
                "</supermemo>"

        Dim expr As New XQueryExpression(query)
        Dim rawXML As String = (expr.Execute(col)).ToXml()

I don't know if this is even the best way to go about it. If anyone can see why I might be getting different output or suggest a better way to execute an XQuery is ASP.net, I'm open to all ideas.
