When I use QDomDocument with HTML content, it fails to set content if there is a <!doctype html> at the beginning of the document. But actually why?!
for example consider the following snippet of code:
QDomDocument doc;
QString content = "<!doctype html><html><body><a href='bar'>foo</a></body></html>";
qDebug() << doc.setContent(content,false,0,0);
QDomElement docElem = doc.documentElement();
QDomNode a = docElem.firstChild();
qDebug() << doc.childNodes().size() << docElem.childNodes().size();
nothing but a list of falses are the output of this code!
