Question

In JAVA I copy nodes from one XML document to another new document using importNode. In original document there is an xmlns defined, but in output document I would like to not have xmlns defined per each element that I copied. How to do it?

Using javax.xml.transform.Transformer with XSL defined as below seems to be a good solution:

    String stylesheet = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>" +
            "<xsl:stylesheet version=\"1.0\" xmlns:xsl=\"http://www.w3.org/1999/XSL/Transform\">" +
            "<xsl:output method=\"xml\" version=\"1.0\" indent=\"no\"/>" +
            "<xsl:template match=\"*\">" +
            "<xsl:element name=\"{local-name()}\">" +
            "<xsl:for-each select=\"@*\">" +
            "<xsl:attribute name=\"{local-name()}\">" +
            "<xsl:value-of select=\".\"/>" +
            "</xsl:attribute>" +
            "</xsl:for-each>" +
            "<xsl:apply-templates/>" +
            "</xsl:element>" +
            "</xsl:template>" +
            "</xsl:stylesheet>";

    StreamSource xslSource = new StreamSource(new StringReader(stylesheet));
    Transformer transformer = tf.newTransformer(xslSource);
