XML + XSLT mit QT

Hey @all,

I think i have somewhere read that XSLT isn't supported by QT at the moment.
Currently I use QT 4.4 for Windows. My Problem now is to use WebView/WebKit.
To work with XML and XSLT i decided to try Xerces-c and Xalan-c within my QT Project, but now I can't compile it.
My Compiler is MinGW.

Code:

When i try to compile i get the following error:

Are you sure that those libraries were compiled for MinGW? There's "msvc_60" at the end of directory names.

For xerces as an example I can only download the following sources:

Can I also use linux-gcc_3_4 for MinGW?

I've never used xerces-c with MinGW, but I think you should try to compile it from sources.

See this: http://xerces.apache.org/xerces-c/bu...nix.html#MinGW
