QXmlStreamReader not giving all the attributes of an element

[rawfool]

Hi,
I'm trying to parse an xml file and when I try to read through the first element, I'm not getting all the corresponding attributes of that element. Only a few are getting noticed. Would be of great help if someone help me in finding the issue.

My xml file is

<nvd xmlns="http://scap.nist.gov/schema/feed/vulnerability/2.0" xmlns:cpe-lang="http://cpe.mitre.org/language/2.0" xmlns:vuln="http://scap.nist.gov/schema/vulnerability/0.4" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:scap-core="http://scap.nist.gov/schema/scap-core/0.1" xmlns:cvss="http://scap.nist.gov/schema/cvss-v2/0.2" xmlns:patch="http://scap.nist.gov/schema/patch/0.1" nvd_xml_version="2.0" xsi:schemaLocation="http://scap.nist.gov/schema/patch/0.1 http://nvd.nist.gov/schema/patch_0.1.xsd http://scap.nist.gov/schema/scap-core/0.1 http://nvd.nist.gov/schema/scap-core_0.1.xsd http://scap.nist.gov/schema/feed/vulnerability/2.0 http://nvd.nist.gov/schema/nvd-cve-feed_2.0.xsd" pub_date="2011-10-23T16:00:27">

My code to to find the attributes of an element -

#include <QCoreApplication>
#include <QDebug>
#include <QXmlStreamReader>
#include <QFile>
 
int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);
 
    QFile file("C:/Users/shravan/Documents/rahul_prac/test.xml");
    if(!file.open(QFile::ReadOnly)) { qDebug() << "Cannot read file" << file.errorString(); }
 
    QXmlStreamReader xml(&file);
    while(!xml.atEnd())
    {
        if(xml.isStartElement())
        {
            if(xml.name() == "nvd")
            {
                int count = xml.attributes().count();
                for(int i = 0; i < count; i++)
                {
                    qDebug() << xml.attributes().at(i).name().toString()
                             << ":  "
                             << xml.attributes().at(i).value().toString();
                    qDebug() << "\n\n";
                }
            }
        }
        xml.readNextStartElement();
    }
 
    return a.exec();
}

#include <QCoreApplication>

#include <QFile>

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);

    QFile file("C:/Users/shravan/Documents/rahul_prac/test.xml");
    if(!file.open(QFile::ReadOnly)) { qDebug() << "Cannot read file" << file.errorString(); }

    QXmlStreamReader xml(&file);

There are more attributes in the xml than what I get in the result. I'm thinking what could possibly be wrong. Thanks.

Thanks

You have all the attributes that are not related to declaring a namespace, i.e. All the attributes with names not starting "xmlns".

You can use namespaceDeclarations() to access the namespace information. Alternatively, you can disable namespace handling with a property of the QXmlStreamReader.
