Hi Christian, This looks like a bug to me. Note that your test program works for all sources except StAXSource if you use XSLTC instead of the interpretive processor (org.apache.xalan.xsltc.trax.TransformerFactoryImpl rather than org.apache.xalan.processor.TransformerFactoryImpl).
Could you please open a bug in JIRA? http://issues.apache.org/jira/browse/XALANJ Thanks, Kevin Cormier Software Developer, XSLT Development IBM Toronto Lab, D1-435 E-mail: [EMAIL PROTECTED] Christian Koppen <christian.koppen @volkswohl-bund.d To e> xalan-j-users@xml.apache.org cc 04/27/2007 10:08 AM Subject Namespace declarations are lost on transformation to DOMResult I have a problem with Xalan 2.7. Have a look at the following snippet: <a:a1 xmlns:a="http://a"; xmlns:b="http://b"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";> <a:a2 xsi:type="b:B"/> </a:a1> As you can see, the value of the attribute 'xsi:type' contains a namespace prefix, which is declared in the root element. When I read this document as a StreamSource or SAXSource and transform it with Xalan into a DOMResult, the namespaces are invalid because the namespace declaration 'xmlns:b="http://b";' is lost: <a:a1 xmlns:a="http://a";> <a:a2 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:type="b:B"/> </a:a1> When I try to read the document as a DOMSource and try to transform it into a DOMResult, an exception occurs ('NAMESPACE_ERR: An attempt is made to create or change an object in a way which is incorrect with regard to namespaces.'). I attached the example code and output. Can somebody tell me if I'm doing something wrong, or if this is a bug in Xalan?
