How to read language name from xml as it is

Srujan18

I am trying to parse an XML file for the first time and I got a requirement like I need to read different country codes and their respective languages from the XML file as it is. And need to display them in UI. Now for my task to complete, there is a hurdle like "reading different country language name as is"!! I am able to read it but not as is. Can anyone help me to get rid of this hurdle?

For your information, the sample XML file looks like the following...

Sorry if I make any querying mistakes. Thank you in advance!

What exactly do you have problem with? What do you mean by "I am able to read it but not as is."?

Please show:

relevant parts of your code

what output you expect to get instead

Okay. Please find the below code.

void parseXMLFile()
{
    QStatusBar *statusBar = new QStatusBar(this);
    QFile *xmlFile = new QFile("xmlfilename.xml");
    if (nullptr != xmlFile) {
        if (!xmlFile->open(QIODevice::ReadOnly | QIODevice::Text))
        {
            statusBar->showMessage("Unable to open xml file!");
        }
        else
        {
            QXmlStreamReader xmlStreamReader(xmlFile);
            while(!xmlStreamReader.hasError() && !xmlStreamReader.atEnd())
            {
                // Read next element
                QXmlStreamReader::TokenType tokenType = xmlStreamReader.readNext();

                //If token type is just start document then go for next
                if ( tokenType == QXmlStreamReader::StartDocument)
                    continue;
                // If token type is start element then read it
                if ( tokenType == QXmlStreamReader::StartElement )
                {
                    if (xmlStreamReader.name() == "countries")
                        continue;
                    if (xmlStreamReader.name() == "country")
                    {
                        parseCountry(xmlStreamReader);
                    }
                }
            }
        }
    }
}

void parseCountry(QXmlStreamReader &xml)
{
    QMap<QString, QString> countryCodeNameMap;
    QXmlStreamAttributes attributes = xml.attributes();

     if (attributes.hasAttribute("code") && attributes.hasAttribute("iso"))
     {
            qDebug()<< "code: " << attributes.value("code").toString();
            qDebug()<< "iso: " << attributes.value("iso").toString();

            xml.readNext();
            qDebug() <<"xml text: "<<xml.text().toString();

            countryCodeNameMap[attributes.value("code").toString()] = xml.text().toString();
    }

    QMapIterator<QString, QString> mapIter(countryCodeNameMap);
    while(mapIter.hasNext()) {
        mapIter.next();
        m_countryMap.insert(mapIter.key(),mapIter.value());
    }
}

Output:
code: "JP"
iso: "392"
xml name: "country"
xml text: "???"

Expected output:
code: "JP"
iso: "392"
xml name: "country"
xml text: "日本語"

I hope I have answered your question by providing the necessary information!

Is the XML file marked as using UTF-8 encoding?

Srujan18

No, I guess. I am using a simple .xml file to parse. In code also I am not parsing using any encoding technique. Did I answer your question? If not can you please explain what you are expecting?

This does not matter as long as there is a correct header: https://www.educba.com/xml-encoding/

Where do you develop? On Windows? If so then qDebug() will not output anything useful as long as your locale is not japanese. Use a QLabel or QMessageBox instead.

I am working on the Windows platform. It worked when I pass to the UI element. Thank you!
