Using the Qt XML Library for Easy Operation
Basically I want to use the XML parser from Qt in my existing project. I've only used Qt before, and this has been with Qt Designer, and I haven't had much luck finding anything on Google about how to simply use the XML library.
I have loaded a webpage with one big list and I want to parse it and add each list item to a C ++ list. I found this sample code on the Ubuntu forums ...

I want to use this, except I need to know what exactly I need to add to the project in order to access it.
Another little question - QDomDocument seems to be for files (makes sense), but I have XML in line. What part of the XML library works for string content?

The following code should give you a quick idea of what to do with Qt XML functions for what you need.
#include <list>
#include <QDomDocument>
#include <QFile>
int main()
{
QString filename("myfile.xml");
std::list<QString> result;
int errorLine, errorColumn;
QString errorMsg;
QFile modelFile(filename);
QDomDocument document;
if (!document.setContent(&modelFile, &errorMsg, &errorLine, &errorColumn))
{
QString error("Syntax error line %1, column %2:\n%3");
error = error
.arg(errorLine)
.arg(errorColumn)
.arg(errorMsg);
return false;
}
QDomElement rootElement = document.firstChild().toElement();
for(QDomNode node = rootElement.firstChild();
!node .isNull();
node = node .nextSibling())
{
QDomElement element = node.toElement();
result.push_back(element.tagName());
}
return 0;
}
UPDATE I believe you only need the core Qt library as well as the XML library.

You have to add QtXml
to .pro file and includeQDomDocument
or include QDomDocument
, for example
include <QtXml/QDomDocument>
