Problem querying a XSLT stylesheet

I loaded a XSLT stylesheet into a XMLDocument to retrieve some of the data.
I received an exception when the SelectNodes method was invoked. The
message was "System.Xml.XPa th.XPathExcepti on - Namespace Manager or
XsltContext needed. This query has a prefix, variable, or user-defined
function."
Q324899

I queried MSDN for Namespace Manager and found this article: "Manage
namespaces Using the XmlNamespace Manager"
http://msdn.microsoft.com/library/de...aceManager.asp

So, based upon the article, I modified my code to look like this:

TemplateDoc = New Xml.XmlDocument
TemplateDoc.Loa d(Filename)

Manager = New Xml.XmlNamespac eManager(Templa teDoc.NameTable )
' also tried this...
' Manager.AddName space("mbe", "http://dummy.com")
Manager.AddName space("xmlns:mb e", "http://dummy.com")
Manager.PushSco pe()

Nodes = TemplateDoc.Sel ectNodes("//mbe:Parameters/parameter")

But, I'm still getting the exception. Anyone have any suggestions?

For what it's worth, I also queried MSDN for XsltContext. The web page for
XsltContext said to refer to Q324899 for more information. Querying on
Q324899 just brought me back to the link above.

Richard

P.S.
Here's what the file looks like:

<xsl:styleshe et xmlns:xsl="http ://www.w3.org/1999/XSL/Transform"
version="1.0" xmlns:mbe="http ://dummy.com">
<mbe:Parameters >
<parameter name="value1" required="yes" />
<parameter name="value2" />
</mbe:Parameters>

<xsl:output method="html" />
<xsl:template match="*" >
<html>
<body>
Sample Table
<table>
<xsl:for-each select="Data">
<tr>
<td>Title: </td>
<td><xsl:valu e-of select="Title" /></td>
</tr>
</xsl:for-each>
</table>
</body>
</html>
</xsl:template>
</xsl:stylesheet>

You need to pass the namespace manager as the second argument to
SelectNodes.

Thank you, that was it. Didn't even notice that SelectNodes took a second
parameter.

Hi all, I'm having a bizarre problem converting XML files to HTML using an XSLT. The problem is only occuring in my Netscape 7.0 browser. What makes it more bizarre is that it is only happening when I put my XML files and the .xsl files on my ISP's system for my home page. If I try to open the XML files in Netscape 7.0 on my own machine (ie, not on the ISP's system), the pages convert file and the result is displayed in HTML.

Hello, I have sort of a big problem. I would really appreciate any help you could give me. I made a web service in C++ that throws XML to the client (browser). But, the XSLT transormation (xml->html) doen't happen! I have XSLT files for this, they work, I mean when I put the output of the app as an XML file on some server, and make it use the XSLT files to transform into HTML, it works, I get a HTML page.
