bug XPath in XSLT?

Hello all,

I've the following simple code scratch:

Code:

QCoreApplication xApplication(argc, argv);
 
    QXmlQuery xQuery(QXmlQuery::XSLT20);
    QBuffer xOriginalContent;
    QString xXMLContent = "<?xml version=\"1.0\" encoding=\"utf-8\" ?><folder id=\"0\" name=\"root\" is_expanded=\"false\"></folder>";
    xOriginalContent.setData( xXMLContent.toAscii() );
    xOriginalContent.open(QBuffer::ReadWrite);
    xOriginalContent.reset();
 
    xQuery.setFocus(&xOriginalContent);
    QString xRequestString;
    xRequestString += "<?xml version=\"1.0\" encoding=\"utf-8\"?>"
                                "<xsl:stylesheet version=\"2.0\" xmlns:xsl=\"http://www.w3.org/1999/XSL/Transform\">"
                                "   <xsl:template match=\"/\">"
                                "       <xsl:apply-templates/>"
                                "   </xsl:template>"
                                "   <xsl:template match=\"folder\">"
                                "       <folder name=\"{@name}\" id=\"{@id}\"  is_expanded=\"{@is_expanded}\">"
                                "           <xsl:copy-of select=\"child::node()\"/>"
                                "           <xsl:if test=\"@id=0\">"
                                "               <folder id=\"1\" name=\"name\"> </folder>"
                                "           </xsl:if>"
                                "       </folder>"
                                "   </xsl:template>"
                                "   <xsl:template match=\"*\">"
                                "       <xsl:copy-of select=\".\"/>"
                                "   </xsl:template>"
                                "</xsl:stylesheet>";
 
    xQuery.setQuery(xRequestString);      
    assert(xQuery.isValid());
    QBuffer xOutputContent;
    xOutputContent.open(QBuffer::ReadWrite);
    xOutputContent.reset();
    std::string str1(xOriginalContent.data());
    xQuery.evaluateTo(&xOutputContent);
    xXMLContent = xOutputContent.data() ;
    std::string str(xOutputContent.data());
 
	return xApplication.exec();

I expect the following result:

but have the following

As you can see two of three XPath expressions(<folder name=\"{@name}\" id=\"{@id}\" is_expanded=\"{@is_expanded}\">) weren't executed at all! Does anyone have the experience with such a problem?
All your attempts to help will be appreciated
