Rodolfo VegasSubject: Error when generating .NET code for pipeline
Author: Rodolfo Vegas
Date: 30 Jan 2008 06:10 AM
I've set up a pipeline that transforms 8 XML files (into another 8 XML files, adding some structure) with 8 corresponding XSL Transformations and after that merges the 8 resulting files into one only XML file using another XSL Tranformation.

It does the job well, but now I'm trying to generate the .NET C# code and I get the following error message:

Error: Internal error: The method getXPathDocParmCode() is not implemented for class com.stylusstudio.xmlpipeline.deployers.inline.edge.FileEdge$Net.

Could you help please?

I'm using Stylus Studio 2008 Enterprise build 1050e.

Hi Rodolfo,

Could you please send us the pipeline and supported files at

Hi Ivan, thanks for your quick response.

I have to make a correction regarding my first post: the pipeline executes well, but with Saxonica Saxon execution framework. With Microsoft .NET execution framework selected (with both .NET XslTransform and XslCompiledTransform XSLT processors selected) it reports the following error:

"System.Xml.XPath.XPathException: Namespace Manager or XsltContext needed. This query has a prefix, variable, or user-defined function.
at MS.Internal.Xml.XPath.CompiledXpathExpr.get_QueryTree()
at System.Xml.XPath.XPathNavigator.Evaluate(XPathExpression expr, XPathNodeIterator context)
at System.Xml.XPath.XPathNavigator.Evaluate(String xpath)
at __process(Char* xmlFileName, Char* xsltFileName, IMSXMLDriver* pDriver)
Error: XSLT processing by XSLT node 'Fusión de ficheros' failed: System.Xml.XPath.XPathException: Namespace Manager or XsltContext needed. This query has a prefix, variable, or user-defined function.
at MS.Internal.Xml.XPath.CompiledXpathExpr.get_QueryTree()
at System.Xml.XPath.XPathNavigator.Evaluate(XPathExpression expr, XPathNodeIterator context)
at System.Xml.XPath.XPathNavigator.Evaluate(String xpath)
at __process(Char* xmlFileName, Char* xsltFileName, IMSXMLDriver* pDriver)"

The XSLT node called 'Fusión de ficheros' is the last one, which has to merge the 8 XML files into the one only final XML.

I wonder if it has something to do with the fact that I use a global variable for each of the 8 files, and also have one of these files as the source XML declared in the Scenario properties of the XSLT file. So I have 9 input ports for the XSLT node, and, although the match attribute for the template is set to "/", mapping the root node of this last file (if I'm right), all the data used in the template are related to the files being pointed to by the global variables.

To me (but I'm just a begginer in the XML world), the message seems to indicate that the XSLT processor is not able to get/construct a node-tree to apply the transformation on, maybe due to the fact that I don't explicitly use any data of the XML file the input port is pointing to.

One question about this: Isn't there any way of suppressing this input port? (not needed in my case, as that file is referenced by one of the 8 global variables).

On another way: Do you really need me to send you all the files? 8 XML original source files, 8 XML transformed 'output' files, 1 final XML file, 9 XSLT files and 1 pipeline file (27 in total if I don't forget any).

Rgds,
Rodolfo

The error you are reporting now is clearly different from you have reported before.

The Microsoft .NET XSLT processor is XSLT 1.0 only, therefore the main input is required. While Saxonica Saxon supports also XSLT 2.0 where the main input document is optional.

I am not completely convinced that is the only problem you are facing.

If you want us to take a closer look, please zip everything together and send it to stylus-field-report@progress.com

Hope this helps

Hi Ivan

After following your advice and updating to build 1050g I've been finally able to run the pipeline and generate the .NET code.

Thank you very much for your support. I really appreciate your quick response and how efficient it has been.

Your support is a really added value to the already impressive tool that Stylus Studio is on itself.

Regards,
Rodolfo
