I spend two day to dispay and edit the XSL-Fo format is similar from dock book KDE..
now i can not grab QTextDocument to resave to xml file.
Question:
Why QTextFrame can not find image or table? inside a QTextFrame::iterator from QTextDocument

Or is image part from fragment? how grab this?

i have one image and one table inside and iterator not find? why .. pleas help .
I not found any sample to iterate QTextDocument http://doc.trolltech.com/4.2/richtext-structure.html


Qt Code: 
  1. //////QTextDocument *w3 = fop.GetDoc() [ return QTextDocument->clone() ] XSL-FO format ;
  2.     /////QTextFrame  *Tframe = w3->rootFrame();
  3.  
  4.     int speed = 0;
  5.     qDebug() << "### iterator start  ############################" << speed;
  6.  
  7.     /* QTextFrameFormat QTextFrame::frameFormat() const  */
  8.  
  9.      QTextFrame::iterator it;
  10.      for (it = Tframe->begin(); !(it.atEnd()); ++it) {
  11.          speed++;    /* to find tree structure */
  12.          QTextFrame *childFrame = it.currentFrame();
  13.          QTextBlock para = it.currentBlock();
  14.  
  15.          if (childFrame)  {
  16.              qDebug() << "### frame " << speed;
  17.  
  18.          } else if (para.isValid()) {
  19.              qDebug() << "### block " << speed << " Paragraph ->" << para.text();
  20.  
  21.              if (para.charFormat().isValid()) {    /* QTextCharFormat  */
  22.                 QTextCharFormat  subpara = para.charFormat();
  23.  
  24.                  qDebug() << "### inline span " << speed;
  25.  
  26.                  if ( subpara.toImageFormat().isValid() ) {
  27.  
  28.                     QTextImageFormat Pic =  subpara.toImageFormat();
  29.                      qDebug() << "### image " << speed;
  30.  
  31.                  } else if ( subpara.toTableFormat().isValid() ) {
  32.  
  33.                      QTextTableFormat Ta = subpara.toTableFormat();
  34.                      qDebug() << "### table " << speed;
  35.                  }
  36.  
  37.  
  38.  
  39.              }
  40.  
  41.  
  42.  
  43.          } 
  44.      }
  45.      qDebug() << "### iterator end  ############################" << speed;
