Editing XML file from Qt

[VJain85]

Can anyone tell how can I edit an XML file from my Qt C++ code?

You can use the (deprecated) QtXml module, or the StAX API, directly in Qt core IIRC.

Note that I have used this QtXML module for some work, and it was fine. I think it is deprecated because nobody wants to maintain it, and it might have some oddities, rather than because it does not work or goes wrong.

can we do this using SAX handler?

What do you mean by SAX handler ?

The QXmlStreamReader is a SAX interface.

@VJain85
If you want to do your processing via the QXmlStreamReader/Writer SAX-type parser that is fine. Note however that means you will not be editing the XML "in place"/"in memory", instead you will be reading the file incrementally and outputting the edited XML to a new file as you go along.
