Contents

Overview

This code snippet demonstrates how to use QDomDocument to represent an XML document.

Note: In order to use this code, you need to have Qt for S60 installed on your platform.


Preconditions


Header

#include <QDomDocument>
#include <QNetworkReply>
#include <QFile>


Create QDomDocument

From file:

QDomDocument doc("mydocument");
QFile file("mydocument.xml");
if (!file.open(QIODevice::ReadOnly))
return;
if (!doc.setContent(&file)) {
file.close();
return;
}
file.close();

From HTTP reply QNetworkReply:

QNetworkReply* createDom(QNetworkReply* reply)
{
QDomDocument* doc = new QDomDocument();
doc->setContent(reply);
return doc;
}


Getting data from QDomDocument

Example XML document:

<person>
<id>1</id>
<firstname>John</firstname>
<lastname>Smith</lastname>
</person>

Getting data from QDomDocument:

QDomElement root = domDocument->documentElement();
 
if (root.tagName() == "person")
{
qDebug() << root.firstChildElement("id").text();
qDebug() << root.firstChildElement("firstname").text();
qDebug() << root.firstChildElement("lastname").text();
// TODO: Store data, this code only debugs data into log
}
