Hi Brian,

thanks for your response and yes you got me right i think. Just the problem is, i don't wanna have "manual" steps like copy and paste, creating word document etc. during the spell check

The xml structure is not so simple and messing around with the xml code during the spell check would produce a lot of errors. This is why i was seeking for a fully automated solution. i was checking, wether i can use word-spell through the vba api but i doesnt seem to work in a gentle way.

So finally i came to the solution using a online-service which provides http requests to check the spelling for a certain amount of text.

So my data flow finally goes like:

XML => WPF-GUI => HTML-API => WPF-GUI => XML => XSLT => HTML => WiN-Copy/Paste => WORD => PDF
