You may start with reading docs:

• QDomDocument
• QDomElement

pay special attention to "Detailed Description" sections. There are example pieces of code..

If you need DOM functionality, then you need to recurse over children of each element looking for a node you need, for example:

QDomElement findElement(QDomElement parent, const QString &textToFind){
  for(QDomElement elem = parent.firstChildElement(); 
      !elem.isNull();
      elem = elem.nextSiblingElement()){
    if(elem.text()==textToFind) return elem;
    QDomElement e = findElement(elem, textToFind); 
    if(!e.isNull()) return e;
  }
  return QDomElement();
}

QDomElement findElement(QDomElement parent, const QString &textToFind){
  for(QDomElement elem = parent.firstChildElement(); 
      !elem.isNull();
      elem = elem.nextSiblingElement()){
    if(elem.text()==textToFind) return elem;
    QDomElement e = findElement(elem, textToFind); 
    if(!e.isNull()) return e;
  }
  return QDomElement();
}
