Hi

How to update a textnode data in xml through QDomElement.
I have following code

Qt Code: 
  1. static QDomDocument doc;
  2.     static QDomElement root,root1;
  3.     QDomElement statement, action_node, condition_node;
  4.     QDomText id_text;
  5.     root = doc.createElement("root");
  6.     QFile *file = new QFile("E:/new.txt");
  7.     if(!file->exists())
  8.     {
  9. 	file->open(QIODevice::WriteOnly);
  10. 	QDomElement id = doc.createElement("id");
  11. 	id_text = doc.createTextNode("0");
  12. 	root.appendChild(id);
  13. 	id.appendChild(id_text);
  14. 	doc.appendChild(root);
  15.     }
  16.     else
  17.     {
  18. 	file->open(QFile::ReadWrite);
  19. 	doc.setContent(file);
  20. 	root1 = doc.documentElement();
  21. 	QDomElement node = root1.firstChildElement("id");
  22. 	QString string_data = node.text();
  23. 	int a = string_data.toInt();
  24. 	qDebug()<<string_data;
  25. 	string_data.clear();
  26. 	id_text = doc.createTextNode("Qt");  // Here i want to write Qt but it is getting write 0Qt on the textnode.
  27. 	node.appendChild(id_text);
  28. 	statement = doc.createElement("statement");
  29. 	condition_node = doc.createElement("condition");
  30. 	action_node = doc.createElement("action");
  31. 	QDomText condition_text = doc.createTextNode(condition_text_edit->toPlainText());
  32. 	QDomText action_text = doc.createTextNode(action_text_edit->toPlainText());
  33. 	statement.setAttribute("id", i);
  34. 	statement.appendChild(condition_node);
  35. 	statement.appendChild(action_node);
  36. 	condition_node.appendChild(condition_text);
  37. 	action_node.appendChild(action_text);
  38. 	root1.appendChild(statement);
  39.  
  40. //	QString str = statement.attribute("id");
  41. //	qDebug()<<str.toInt();
  42. 	file->seek(0);
  43.  
  44.     }
  45.     QTextStream out(file);
  46.     doc.save(out, Indent);
To copy to clipboard, switch view to plain text mode 
So i want to update the textnode value while it is getting append in previous value.
Please anyone help me.
Waiting for response.
