Can I use something like that:

<xsl:value-of select="path1[criteria1]path2[criteria2]element/text()">

What I am trying to do is selecting one name/value pair value after another from several named name/value sets.

Thanks!

What you have is not syntactically correct. You might want

Syntactically correct or not - it is unimportant. What I would like to know is whether I can have multiple criteria or not. Does your snippet work? I am in Biztalk and that does not work for me for some reason.

You can have multiple predicates e.g.
  foo[predicate1][predicate2]
You can also use boolean operators 'and' or 'or' e.g.
  foo[predicate1 and predicate2]
  foo[predicate1 or predicate2]

As for a working snippet, you will need to post the input XML first to allow us the suggest an XPath expression specific to that input.

There's no point saying something doesn't work unless you tell us exactly what you did and exactly how it failed.
