Thanks Constantin,

I have tried that, but the HTML string generated by Excel is not a valid XML file :/

The html string has, for example, something like:
____
<body link="#0000d4" vlink="#993366">
<table border=0 cellpadding=0 cellspacing=0 width=190 style='border-collapse:
 collapse'>
___

and QDomDocument::setContent complains that :
"unexpected character" on line 3 and column  15 

I guess that is due to the fact that the attribute (eg border) values are not comma-encapsulated.

Yeah, i know, Excel is bad :)

Any other hints welcome. I'll try parsing with reg exp.

Best-
Nicolas

This may not be the best solution, but I guess you could try to parse your  
HTML file manually as an XML document.
