This is my simple XML file:

<question>
<from>me</me>
<to>you</to>
<message>How to I parse this file?</message>
</question>

The intention is to get the different words out of the XML elements. The final result should be "me, you, How to I parse this file?".

Please guide me with a bit of code is possible.

Thank you.

The QDom classes are typically used as follows:



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

// print out the element names of all elements that are direct children
// of the outermost element.
QDomElement docElem = doc.documentElement();

QDomNode n = docElem.firstChild();
while(!n.isNull()) {
QDomElement e = n.toElement(); // try to convert the node to an element.
if(!e.isNull()) {
cout << e.tagName() << endl; // the node really is an element.
}
n = n.nextSibling();
}

The example given above prints the name of the elements, not the content of them.

What is the function call that prints the content of the elements. For example:

<xml>hello</xml>

I would like to get the content of the element <xml>, in this case the content should be "hello".

How ?

Did you take a look at the QDomElement documentation (http://doc.trolltech.com/4.1/qdomelement.html#text)?

In such a simple case it'll be faster to remove all xml tags :)

Use QDomElement::text() instead of QDomElement::tagName() to get the contents of XML instead of getting the tagnames.

You can alternatively use QXmlContentHandler/QXmlSimpleReader classes to get the contents of the XML.

Hi wysota, I posted a very simple example. In reality the Xml file is much larger.

It doesn't matter that it is larger. It's important that you need the text in sequencial order and that you don't use attributes.
