How about:

<xsl:apply-templates select="//blog[author_id = ($AuthorId,
author_id)[1]][category_id = ($CategoryId, category_id)[1]]"/>

...although there might be a nicer way.  Even so, sometimes its better
to have more readable code spread over a few lines than one that takes
you a few goes to understand what it's doing :)
