Need to apply automatically an XSLT to an XML in Microsoft Word

I've got an XML file which is linked to an XSLT file. The output of the xslt is formal HTM开发者_StackOverflowL.

Actually, when i'm opening the XML with Word, a "pop-up" ask me which xsl i want to apply, but by default we see the xml data. Once i've selected my xsl, the html page is rendered.

My question is a quite simple one, how can i apply automatically the xsl ?
