Pass xml file from javascript to qt using qwebkit bridge
Hi!
Have some problem with trying to pass a xml file as a domdocument from javascript to my c++ code in qt. Is there any way doing this?
The reason is that I need to parse a xml file using xslt using but I find it to time inefficient to first convert the xml document to a string and then send it to qt. Would be much bether if I can just send it directly. Or is there maybe any other approach doing this that would be bether? Also how good is the internal xslt transformation in qt compare to other libraries for example xalan? As I have understand it you have to use an external library to parse xml files with xslt to get a good result viewing webpages that is using this? Many questions I know but have been sitting with this for a while and would really appreciated any help I can get :)

Using what API?

Xalan is more complete. WebKit should have its own XSL transformer though that should be complete (feature-wise).

I don't understand what you mean.

I am pretty new to these things but and have only been programming in c++ before but any API that make it possible to pass a xml domdocument in a similar way to the way qwebelement can pass html domdocument from javascript to c++ would be great.

There is no common API between WebKit and QDomDocument. You can access the page DOM directly from C++ using QWebElement and family, if you want but you can't "convert" it to QDomDocument.

Is there any simple way to implement for webkit to be able to send new user defined types then from javascript to c++? QWebelement doesn't work for xml files as i understand it...

You can expose your own C++ API to WebKit.

Can you explain or link any webpage that shows more exactly how to do that? Been looking for it myself but haven't been able to find anything...
