Using the facilities of the QtXml or QtXmlPatterns module or QXmlStreamReader.

How about you tell us what you have tried?

[Gokulnathvc]

I have tried with QDocDocument and I am always getting values as 1.4.1.2011.4.1.201?

QList< QMap<QString,QString> > Package;
 
    /* QDomDocument takes any QIODevice. as well as QString buffer*/
    QDomDocument doc("mydocument");
    if (!doc.setContent(xmlFile))
    {
        return;
        }
 
    //Get the root element
    QDomElement docElem = doc.documentElement();
 
    // you could check the root tag name here if it matters
        QString rootTag = docElem.tagName(); // == package
        QString fll = docElem.text();
 
        // get the node's interested in, this time only caring about person's
        QDomNodeList nodeList = docElem.elementsByTagName("folder");
 
        //Check each node one by one.
        for(int ii = 0;ii < nodeList.count(); ii++)
    {
                QMap<QString, QString> firmwarefolder;
 
                // get the current one as QDomElement
        QDomElement el = nodeList.at(ii).toElement();
 
        firmwarefolder["folder"] = el.attribute("folder"); // get and set the attribute ID
        firmwarefolder["file"]   = el.attribute("file");
 
        //get all data for the element, by looping through all child elements
                QDomNode pEntries = el.firstChild();
        while(!pEntries.isNull()) {
                QDomElement peData = pEntries.toElement();

I have added these codes. But am not getting the folder name and file name.. Whats wrong with this?

[wysota]

The attribute you are looking for is called "name" and not "folder".

[Gokulnathvc]

I have tried with that and got the values, but still it is showing me different values not the output what i have mentioned above

How to get the values in first loop as folder = releasesfppro and file = 2234522566 and in second loop as folder = releasebios file = 11841084???

[ChrisW67]

You are getting the text of the <folder> and <file> elements that you are asking for at lines 38 and 40. If you want the value of the name attribute of these elements then you should ask for that.

[Gokulnathvc]

I have updated the code and edited the values in the previous comment. Could you look at that?

[wysota]

Do you understand the difference between XML attribute value and XML tag text?

[Gokulnathvc]

I am new to XML programming. Could you see my updated code and give me suggestion and a solution?

QDomNodeList nodeList = docElem.elementsByTagName("folder");
   for(int k = 0;k < nodeList.count(); k++)
   {
       QDomElement el = nodeList.at(k).toElement();
       firmFolder +=  el.attribute("name");
       firmFolder += "/";
   }
 
   nodeList = docElem.elementsByTagName("file");
   for(int l = 0;j < nodeList.count(); l++)
   {
       QDomElement el = nodeList.at(l).toElement();
       firmFiles += el.attribute("name");
       firmFiles += " ";
   }

QDomNodeList nodeList = docElem.elementsByTagName("folder");
   for(int k = 0;k < nodeList.count(); k++)
   {
       QDomElement el = nodeList.at(k).toElement();
       firmFolder +=  el.attribute("name");
       firmFolder += "/";
   }

   nodeList = docElem.elementsByTagName("file");
   for(int l = 0;j < nodeList.count(); l++)
   {
       QDomElement el = nodeList.at(l).toElement();
       firmFiles += el.attribute("name");
       firmFiles += " ";
   }

I have added these codes. but am getting folder as release/sf/ppro/release/bios and file as 223452256611841084?
But i should get this as release/sf/ppro/ and file 2234522566 for first loop.. and release/bios and file 11841084 for the second loop.. How to get this..

[ChrisW67]

I am new to XML programming. Could you see my updated code and give me suggestion and a solution?

The code has not been changed as far as I can see. There's still the obvious errors at line 38/40

I have already told you what you need to query to retrieve the folder/file name from the <folder>/<file> element, and you are already using the relevant function. Wysota has already given you the name of the attribute you want. If you explain which part you do not understand we can help

[Gokulnathvc]

Kindly check the updated code..
QDomNodeList nodeList = docElem.elementsByTagName("folder");
for(int k = 0;k < nodeList.count(); k++)
{
QDomElement el = nodeList.at(k).toElement();
firmFolder += el.attribute("name");
firmFolder += "/";
}

nodeList = docElem.elementsByTagName("file");
for(int l = 0;j < nodeList.count(); l++)
{
QDomElement el = nodeList.at(l).toElement();
firmFiles += el.attribute("name");
firmFiles += " ";
}
