Question

I have an xml file and an xslt file.

The xml file has a xmlns=”exa:com.test” attribute.

If i remove this attribute in the xml the xpath sentences in my xslt works. But if i leave it, doesnt work.

Im using the following code to mix xml and xslt:

XslCompiledTransform transformer = new XslCompiledTransform();

transformer.Load(HttpContext.Current.Server.MapPath("xslt\\searchresults.xslt"));  

transformer.Transform(xmlreader, null, utf8stringwriter);

What im doing wrong? How could i mix xml and xslt if the xml has the xmlns attribute on top?

Answer 1

The xmlns attribute without prefix name replaces the default namespace, so that your query matches nodes with a different (empty) namespace. You need to use a prefixed namespace in the XSLT XPath queries (or a XmlNamespaceManager for isolated XPath queries) and your queries will work again as expected.

In the XSLT:

<xsl:stylesheet ... xmlns:exa="exa:com.test">

Then, assuming that you used to match for instance xyz, you now change your query like this:

<xsl:template match="exa:xyz"> ...

In general you might want to read some docs on XML namespaces.
