How to save double quotes in XML header using QDomDocument-CodePudding

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.

CodePudding user response：

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.
