I think I am wrong. At least I'm seeing a difference in behavior in
KoXml vs. QDom here. With this input

test.xml:
<foo>
    <bar/>
</foo>

the program

#include <QDebug>
#include <QFile>
#include <QDomDocument>
#include <QDomNode>

int main (int, char **)
{
    QFile file("test.xml");
    QDomDocument doc;
    doc.setContent(&file);
    switch (doc.documentElement().firstChild().nodeType()) {
        case QDomNode::ElementNode:
            qDebug() << "ElementNode";
            break;
        case QDomNode::AttributeNode:
            qDebug() << "AttributeNode";
            break;
        case QDomNode::TextNode:
            qDebug() << "TextNode";
            break;
        default:
            qDebug() << "Unknown";
            break;
    }

    return 0;
}

gives ElementNode as output, while the program

#include <KoXmlReader.h>

int main (int, char **)
{
    QFile file("test.xml");
    KoXmlDocument doc;
    doc.setContent(&file);
    switch (doc.documentElement().firstChild().nodeType()) {
        case KoXmlNode::ElementNode:
            qDebug() << "ElementNode";
            break;
        case KoXmlNode::TextNode:
            qDebug() << "TextNode";
            break;
        default:
            qDebug() << "Unknown";
            break;
    }

    return 0;
}

gives TextNode as output.

Shouldn't KoXml* and QDom* be functionally equivalent?
