c++ - How to parse xml with qt? -

i'm trying parse html page qt using qtxmlquery, with:

query.setfocus(qnetworkreply->readall());   

but receive following error message:

error fodc0002 in tag:trolltech.com,2007:qtxmlpatterns:qiodevicevariable:u,   @ line 3, column 44: entity 'ndash' not declared. 

i think means html page i'm trying read malformed. how fix page ?

first maybe check if ndash declared in xml:

<!entity ndash "&#8211;"> <!-- en dash, u+2013 isopub -->  <!entity mdash "&#8212;"> <!-- em dash, u+2014 isopub -->  

named entities, known internal entities in xml specifications, refer when talk "entities." declare them in either dtd or internal subset (that is, part of statement in document) , use them in document references. during xml document parsing, entity reference replaced representation. in plain english, these entities macros expanded when process document.

example:

<!doctype article public "-//nlm//dtd journal publishing dtd v3.0 20080202//en" "journalpublishing3.dtd" [<!entity ndash "&#x2013;">] 

see here more info

if ok alternatively try else: can use builtin qtwebkit. example:

class mypageloader : public qobject {   q_object  public:   mypageloader();   void loadpage(const qurl&);  public slots:   void replyfinished(bool);  private:   qwebview* m_view; };  mypageloader::mypageloader() {   m_view = new qwebview();    connect(m_view, signal(loadfinished(bool)),           this, slot(replyfinished(bool))); }  void mypageloader::loadpage(const qurl& url) {   m_view->load(url); }  void mypageloader::replyfinished(bool ok) {   qwebelementcollection elements = m_view->page()->mainframe()->findallelements("a");    foreach (qwebelement e, elements) {     // process element e   } } 

to use class

mypageloader loader; loader.loadpage("http://www.google.com") 

you can find wraper here

to retrieve element:

qwebview* view = new qwebview(parent); view.load(qurl("http://www.your_site.com")); qwebelementcollection elements = view.page().mainframe().findallelements("a");
