I have a gpx file , basically that is a xml file. I want to read latitude and longitude values from that. Below i have posted the sample gpx file.
<gpx>
<wpt lon="80.0124" lat="13.125">
</wpt>
<wpt lon="80.0130" lat="13.124">
</wpt>
<wpt lon="80.0145" lat="13.122">
</wpt>
<wpt lon="80.0120" lat="13.121">
</wpt>
</gpx>
I need to get float values of latitude and longitude. Any help and suggestion is appreciated.
Thank you. Could i get the result without double quotes?
The key class here is QXmlStreamReader.
See the code below to get it work.
<gpx>
<wpt lon="80.0124" lat="13.125">
</wpt>
<wpt lon="80.0130" lat="13.124">
</wpt>
<wpt lon="80.0145" lat="13.122">
</wpt>
<wpt lon="80.0120" lat="13.121">
</wpt>
</gpx>
#include <QXmlStreamReader>
#include <QDebug>
#include <QString>
#include <QFile>
int main()
{
QFile file("test.xml");
if (!file.open(QIODevice::ReadOnly | QIODevice::Text)) {
qDebug() << "File open error:" << file.errorString();
return 1;
}
QXmlStreamReader inputStream(&file);
while (!inputStream.atEnd() && !inputStream.hasError())
{
inputStream.readNext();
if (inputStream.isStartElement()) {
QString name = inputStream.name().toString();
if (name == "wpt")
qDebug() << "lon:" << inputStream.attributes().value("lon").toFloat() << "lat:" << inputStream.attributes().value("lat").toFloat();
}
}
return 0;
}
