QTextFrame::iterator richtext QTextDocument problem?

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. :mad:
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

Code:

---

//////QTextDocument *w3 = fop.GetDoc() [ return QTextDocument->clone() ] XSL-FO format ;
    /////QTextFrame  *Tframe = w3->rootFrame();
 
    int speed = 0;
    qDebug() << "### iterator start  ############################" << speed;
 
    /* QTextFrameFormat QTextFrame::frameFormat() const  */
 
     QTextFrame::iterator it;
     for (it = Tframe->begin(); !(it.atEnd()); ++it) {
         speed++;    /* to find tree structure */
         QTextFrame *childFrame = it.currentFrame();
         QTextBlock para = it.currentBlock();
 
         if (childFrame)  {
             qDebug() << "### frame " << speed;
 
         } else if (para.isValid()) {
             qDebug() << "### block " << speed << " Paragraph ->" << para.text();
 
             if (para.charFormat().isValid()) {    /* QTextCharFormat  */
                QTextCharFormat  subpara = para.charFormat();
 
                 qDebug() << "### inline span " << speed;
 
                 if ( subpara.toImageFormat().isValid() ) {
 
                    QTextImageFormat Pic =  subpara.toImageFormat();
                     qDebug() << "### image " << speed;
 
                 } else if ( subpara.toTableFormat().isValid() ) {
 
                     QTextTableFormat Ta = subpara.toTableFormat();
                     qDebug() << "### table " << speed;
                 }
 
 
 
             }
 
 
 
         } 
     }
     qDebug() << "### iterator end  ############################" << speed;

i found now a QTextBlock::iterator ... from qt4-x11-4.2.3/tools/assistant/mainwindow.cpp

but how find now the internal equivalent <span> tag HTML? is this to a fragment?..

Code:

---

//////QTextDocument *w3 = fop.GetDoc() [ return QTextDocument->clone() ] XSL-FO format ;
    /////QTextFrame  *Tframe = w3->rootFrame();
    int speed = 0;
    qDebug() << "### iterator frame start  ############################" << speed;
 
    /* QTextFrameFormat QTextFrame::frameFormat() const  */
     QTextFrame::iterator it;
     for (it = Tframe->begin(); !(it.atEnd()); ++it) {
         speed++;    /* to find tree structure */
         QTextFrame *childFrame = it.currentFrame();
         QTextBlock para = it.currentBlock();
 
         if (childFrame)  {
             qDebug() << "### frame " << speed;
 
         } else if (para.isValid()) {
             QTextBlockFormat ParentBl = para.blockFormat();
