Question

I have following problem that in a transformation (which is completely done in memory) should recieve an additional XSLT parameter containing another XML stream.
It’s like merging two XML documents together in memory. Writing it down on the drive and load it dynamically is not a possibility.

To develop I use .Net together with Visual Studio 2010.

It’s possible with .NET (i’ve tested 4.0). It worked with following code:

C#:

XslCompiledTransform proc = new XslCompiledTransform();
proc.Load(path + "test_parameter.xslt");

System.IO.TextWriter result = new StreamWriter(path + "result.html");

XmlDocument docA = new XmlDocument();
docA.Load(path + "documentA.xml");

XmlDocument docB = new XmlDocument();
docB.Load(path + "documentB.xml");

XsltArgumentList xsltArgs = new XsltArgumentList();
xsltArgs.AddParam("xmlDoc", "", docB);

proc.Transform(docA, xsltArgs, result);

XSLT:

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

  <!-- THIS FILE GENERATES A SIMPLE HTML  -->
  <xsl:output method="html" indent="yes"/>
  <xsl:param name="xmlDoc" />    

  <xsl:template match="/document">
     <xsl:apply-templates select="$xmlDoc/foo/bar"/>
  </xsl:template>
</xsl:stylesheet>
