How to save double quotes in XML header using QDomDocument

Before opening XML document the header was

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

But after using QDomDocument

if (!file.open((QIODevice::ReadOnly)))
{
    return;
}

QDomDocument document;
if (!document.setContent(&file))
{
    return;
}

file.close();

if (!file.open(QIODevice::Truncate | QIODevice::WriteOnly)) {
    return;
}

QTextStream out(&file);
document.save(out, 2);
file.close();

<?xml version='1.0' encoding='UTF-8' standalone='yes'?>

I know what xml standart allows to use single quotes. But I need to use double quotes.

Solution

  • You could either use QXmlStreamWriter which prefers double quotes, or you could postprocess the string representation of you document before streaming. For example:

    out << document.toString(2).replace('\'', '\"');

    Alternatively, you could also submit a feature request on the Qt issue tracker to add some configuration to QDomDocument and see whether the Qt developers think.
