Saving settings to XML

[arturo182]

Hi.

I'm new to QT, I found this forum very helpful, but now I have a problem that I couldn't find a solution for in old topics.

I'm trying to to save QSettings to XML, I know I have to register a new format, I did all that, I got readXMLfile and writeXMLfile functions from this post, changed them a bit and everything works just fine, except one thing.

If I want two values with same parent element names, they duplicate in XML file, let me give you an example:

the code is:

settings->setValue("themes/author/name", "arturo182");
settings->setValue("themes/author/email", "arturo182@qwerty.com");

settings->setValue("themes/author/name", "arturo182");
settings->setValue("themes/author/email", "arturo182@qwerty.com");

To copy to clipboard, switch view to plain text mode 

xml file looks like this:

<?xml version="1.0" encoding="UTF-8"?>
<settings>
  <themes>
    <author>
      <name>arturo182</name>
    </author>
  </themes>
  <themes>
    <author>
      <email>arturo182@qwerty.com</email>
    </author>
  </themes>
</settings>

<?xml version="1.0" encoding="UTF-8"?>
<settings>
  <themes>
    <author>
      <name>arturo182</name>
    </author>
  </themes>
  <themes>
    <author>
      <email>arturo182@qwerty.com</email>
    </author>
  </themes>
</settings>

and what I'm trying to achieve is:

<?xml version="1.0" encoding="UTF-8"?>
<settings>
  <themes>
    <author>
      <name>arturo182</name>
      <email>arturo182@qwerty.com</email>
    </author>
  </themes>
</settings>

<?xml version="1.0" encoding="UTF-8"?>
<settings>
  <themes>
    <author>
      <name>arturo182</name>
      <email>arturo182@qwerty.com</email>
    </author>
  </themes>
</settings>

I tried almost everything, but as I said, I'm new to QT and not sure how to fix this problem.
Maybe someone has better idea of how to achive what I want to do.
I already checked QDomDocument, QDomElement and all that, but I just love creating XML by using syntax like "parent/child/childchild".

Also it would be nice to have access to attributes like this:

setValue("themes/author[name]", "arturo182");

setValue("themes/author[name]", "arturo182");

well, you must not close all the group-tags

foreach( std::string groupName, groups )
        {
            xmlWriter.writeStartElement( groupName.c_str() );
        }
 
        xmlWriter.writeCharacters( mi.value().toString() );
 
        foreach( std::string groupName, groups )
        {
            xmlWriter.writeEndElement();
        }

foreach( std::string groupName, groups )
        {
            xmlWriter.writeStartElement( groupName.c_str() );
        }
 
        xmlWriter.writeCharacters( mi.value().toString() );
 
        foreach( std::string groupName, groups )
        {
            xmlWriter.writeEndElement();
        }

instead, you need to store the "current" group path in a variable.
Then calculate the path for the next setting: close only the tags (list suffix) no longer in the new path; open the new suffix path tags...

I once posted something like that in http://www.qtcentre.org/forum/f-qt-programming-2/t-qabstractitemmodel-subclass-duplicate-entries-14453.html

Yes that could work if I had similiar paths next to each other, but if I had something like this:

settings->setValue("themes/author/name", "arturo182");
settings->setValue("something/else", "test");
settings->setValue("themes/author/email", "arturo182@qwerty.com");

settings->setValue("themes/author/name", "arturo182");
settings->setValue("something/else", "test");
settings->setValue("themes/author/email", "arturo182@qwerty.com");

I think I should sort the SettingsMap by key before saving, is there a way to do it with one of QT's functions or do I have to do it by myself?
