[Qt-interest] Qt5 and XML DOM

[Jason H]

I used XPath with Qt before it existed (XmlPatterns). How did I do that? 
Recursive QDomNode navigation. With write capability.

XPath is cool, and would be cool if it could write in Qt, but that's only a 
subset of what you can do when you can have the expression return a 
QDomNodeList.  (Or as I prefer QList<QDomNode>)

Which gets me to my next point, Qt needs to have the QDomNode stuff support Qt's 
foreach(){}

And finally, there needs to be some abstract representation of structured data 
that can be mapped in and out of XML space, like a QObject hierarchy. We could 
then convert from any structured data to any other structured data: XML, JSON, 
Python, binary file formats. We can then read in any format and write in any 
format. But once read, we can manipulate it in what ever way we want. All those 
formats are just serializations of structured data.

I've used both libXML2 and Qt QDom - I much prefer QDom. I use to build and 
parse custom XML messages for a distributed system's communication protocol. 
QDom is very straight forwards and a lot less overhead. The libXML2 
implementation required a lot more code to do the same thing, and I was very 
glad to mostly deprecate it. (I still keep it around for some non-Qt 
applications.)

I mainly use xpath (read/write values) and xslt/exslt in libxml2, there is no 
equivalent in Qt.
