Examples of org.apache.xalan.transformer.ResultTreeHandler

org.apache.xalan.transformer.ResultTreeHandler
This class is a layer between the direct calls to the result tree content handler, and the transformer. For one thing, we have to delay the call to getContentHandler().startElement(name, atts) because of the xsl:attribute and xsl:copy calls. In other words, the attributes have to be fully collected before you can call startElement.

        transformer.getTraceManager().fireSelectedEvent(sourceNode, this,
                "select", new XPath(m_selectExpression),
                new org.apache.xpath.objects.XNodeSet(sourceNodes));


      final ResultTreeHandler rth = transformer.getResultTreeHandler();
      ContentHandler chandler = rth.getContentHandler();


      xctxt.pushCurrentNode(DTM.NULL);


      int[] currentNodes = xctxt.getCurrentNodeStack();
