XML Dom parsing function

Hi, everyone! I wanted to thank everybody for the help they've gave me while I've been on these forums. Now, it's my turn to contribute toward this community. I recently wrote a function to read from an XML file using a path. This supports attributes AND indexing. Here it is:

Code:

---

QString XmlUtils::GetData(QString path)
{
    QDomDocument doc("myDocument");
    QFile *xmlFile = new QFile("file.xml");
    doc.setContent(xmlFile);
    QDomElement docElement = doc.documentElement();
    QDomNode node;
    node = docElement.firstChild();
 
    QStringList pathFiles;
    QString returnString;
    pathFiles = path.split("/");
    int curindex = 0;
 
    for(int i = 0; i < pathFiles.length(); i++)
    {
        QString curpath = pathFiles[i];
        if(curpath.startsWith('@'))
        {
            node = node.parentNode();
            curpath = curpath.remove('@');
            returnString = node.attributes().namedItem(curpath).nodeValue();
        }
        else
        {
            if(curpath.contains('['))
            {
                QStringList subPathFile = curpath.split('[');
                QString subIndex = subPathFile[1];
                subIndex = subIndex.remove(']');
                QString subNode = subPathFile[0];
                for(int x = 0; x < node.parentNode().childNodes().length(); x++)
                {
                    if(node.nodeName() == subNode)
                    {
                        if(pathFiles[i] == pathFiles.back())
                        {
                            if(node.parentNode().childNodes().item(subIndex.toInt()).nodeName() == subNode)
                                returnString = node.parentNode().childNodes().item(subIndex.toInt()).firstChild().nodeValue();
                            break;
                        }
                        else
                            node = node.parentNode().childNodes().item(subIndex.toInt());
                    }
                }
               node = node.firstChild();
 
            }
            else
            {
                for(int x = 0; x < node.parentNode().childNodes().length(); x++)
                    {
                        if(node.nodeName() == pathFiles[i])
                        {
                            if(pathFiles[i] == pathFiles.back())
                            {
                                    if(node.nodeName() == pathFiles[i])
                                        returnString = node.firstChild().nodeValue();
                                    break;     
                            }
 
                        }
                        else
                            node = node.nextSibling();
                    }
                node = node.firstChild();
            }
        }
 
    }
    return returnString;
}

How to use it:
Say you have the xml file:

<xml>
<Family>
<Foley>Justin</Foley>
<Foley>Ashley</Foley>
<Foley>Gavin</Foley>
</Family>
</xml>

And you want to get the value of 'Ashley.'
What you would do is:
QString name = XmlUtils->GetData("Family/Foley[1]");
The variable, 'name' would now be index [1] of the nodeset, 'Foley'. Please, enjoy and let me know if anybody does not understand. Praise is also accepted. :)

add the code:

Code:

---

node = node.firstChild();

---

right after line: 22. This will support early attributing. I.E. Family/@Foley/Foley[0]/@First if your XML looks like this:

Code:

---

<xml>
<Family Name="Foley">
<Foley First="Justin">Justin</Foley>
<Foley First="Ashley">asdf</Foley>
<Foley>Gavin</Foley>
</Family>
</xml>

Did you notice QXmlQuery? It makes exactly what your custom function does...

No, I did not. Thank you for enlightening me.

UPDATED CODE:

    QDomNode node;
    node = docElement.firstChild();
 
    QStringList pathFiles;
    QString returnString;
    pathFiles = path.split("/");
 
    for(int i = 0; i < pathFiles.length(); i++)
    {
        QString curpath = pathFiles[i];
        if(curpath.startsWith('@'))
        {
            curpath = curpath.remove('@');
            QString rightNode = pathFiles[i-1];
            if(rightNode.contains('['))
            {
                QStringList rightNodeChildren = rightNode.split('[');
