Description
QDom::setContent creates excess xmlns attribute for child element when enabled namespace processing. For source xml
<?xml version="1.0" encoding="utf-8"?> <ns:root xmlns:ns="example:com"> <ns:child> text </ns:child> </ns:root>
after QDomDocument I get
<?xml version="1.0" encoding="utf-8"?> <ns:root xmlns:ns="example:com"> <ns:child xmlns:ns="example:com"> text </ns:child> </ns:root>
Another problem here it that setPrefix works only for root element. So if I try to change namespace I get
<?xml version="1.0" encoding="utf-8"?> <ns1:root xmlns:ns1="example:com"> <ns:child xmlns:ns="example:com"> text </ns:child> </ns:root>
My code:
#include <QDebug>
#include <QDomDocument>
#include <QDomElement>
#include <QDomAttr>
#define DOC \
"<?xml version=\"1.0\" encoding=\"utf-8\"?>\n" \
"<ns:root xmlns:ns=\"example:com\">\n" \
" <ns:child>\n" \
"text\n" \
" </ns:child>\n" \
"</ns:root>"
int main(int argc, char *argv[])
{
Q_UNUSED(argc);
Q_UNUSED(argv);
QDomDocument doc;
doc.setContent(QString(DOC), true);
doc.firstChildElement().setPrefix("ns1");
qDebug() << qPrintable(doc.toString(2));
return 0;
}
