Hello all,

I've the following simple code scratch:
Qt Code: 
  1. QCoreApplication xApplication(argc, argv);
  2.  
  3.     QXmlQuery xQuery(QXmlQuery::XSLT20);
  4.     QBuffer xOriginalContent;
  5.     QString xXMLContent = "<?xml version=\"1.0\" encoding=\"utf-8\" ?><folder id=\"0\" name=\"root\" is_expanded=\"false\"></folder>";
  6.     xOriginalContent.setData( xXMLContent.toAscii() );
  7.     xOriginalContent.open(QBuffer::ReadWrite);
  8.     xOriginalContent.reset();
  9.  
  10.     xQuery.setFocus(&xOriginalContent);
  11.     QString xRequestString;
  12.     xRequestString += "<?xml version=\"1.0\" encoding=\"utf-8\"?>"
  13.                                 "<xsl:stylesheet version=\"2.0\" xmlns:xsl=\"http://www.w3.org/1999/XSL/Transform\">"
  14.                                 "   <xsl:template match=\"/\">"
  15.                                 "       <xsl:apply-templates/>"
  16.                                 "   </xsl:template>"
  17.                                 "   <xsl:template match=\"folder\">"
  18.                                 "       <folder name=\"{@name}\" id=\"{@id}\"  is_expanded=\"{@is_expanded}\">"
  19.                                 "           <xsl:copy-of select=\"child::node()\"/>"
  20.                                 "           <xsl:if test=\"@id=0\">"
  21.                                 "               <folder id=\"1\" name=\"name\"> </folder>"
  22.                                 "           </xsl:if>"
  23.                                 "       </folder>"
  24.                                 "   </xsl:template>"
  25.                                 "   <xsl:template match=\"*\">"
  26.                                 "       <xsl:copy-of select=\".\"/>"
  27.                                 "   </xsl:template>"
  28.                                 "</xsl:stylesheet>";
  29.  
  30.     xQuery.setQuery(xRequestString);      
  31.     assert(xQuery.isValid());
  32.     QBuffer xOutputContent;
  33.     xOutputContent.open(QBuffer::ReadWrite);
  34.     xOutputContent.reset();
  35.     std::string str1(xOriginalContent.data());
  36.     xQuery.evaluateTo(&xOutputContent);
  37.     xXMLContent = xOutputContent.data() ;
  38.     std::string str(xOutputContent.data());
  39.  
  40. 	return xApplication.exec();

I expect the following result:
<folder name="root" id="0" is_expanded="false"><folder id="1" name="name"/></folder>
but have the following
<folder name="root" id="" is_expanded=""><folder id="1" name="name"/></folder>
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
