Exporting blog

A friend of my has an exciting website and he has a blog page. He has asked me to rebuild his website. Easy enough!
I’ve re-built his website on Netobjects Fusion and it looks great. But now I need to import or embed his blog on his new website. I don’t know too much about blogging – no, I mean, I know nothing about blogging.
How do I do that?
I’ve tried exporting the blog in WordPress and it export it in .xml format – but NOW would you believe: Netobjects Fusion can’t import .xml files….
Hope someone can help me.
