Hi Ralf,
I'll check DIXML out.
Re the compiler error, are you sure it doesn't depend on dicontainers? Your
dihtmlparser installer have 3 files - dicontainer.dcu/.obj/.hpp installed in
the D2010 subfolder, once I delete those 3 files and compile the demos
(tried 3 ones), I got:
[DCC Fatal Error] Common.pas(51): F1026 File not found: 'DIContainers.dcu'
