XSLT - Transformation with usage of default TransformerFactory does not work if namespaces are used without prefixes.

Route: <to uri= "xslt:migration.xsl" /> XSLT stylesheet: migration.xsl < xsl:stylesheet version= "1.0" xmlns:xsl = "http://www.w3.org/1999/XSL/Transform" xmlns:ns1 = "http://ws.legacy.jboss.org/" > < xsl:template match= "@*|node()" > < xsl:copy > < xsl:apply-templates select= "@*|node()" /> </ xsl:copy > </ xsl:template > </ xsl:stylesheet > input: <name xmlns= "my-namespace" > Martin </name> output: < xmlns= "my-namespace" > Martin </> workaround : use saxon transformer factory (option saxon=true) <to uri= "xslt:migration.xsl?saxon=true" />
