Thanks Florent for your suggestion.

I did solve the problem, however, using a different approach. I'm using XSLT 2.0 so I just used the matches function using a regular expression:
matches(@style, 'font-family: (font1|font2)')
I converted the $fonts into a string separated by the '|' operator.

have an xml with elements like these:

and i have an variable in my xsl file like this:
<xsl:variable name="fonts" as="xs:string+"
i want to match the text nodes that are child of an
element with a style attribute that matches any of the
fonts in $fonts. What is the xpath expression that can do
  It depends.  The most simple way is to use contains().  It
is not the a perfect way, but it can be acceptable if the
font names are complex enough and you know you'll never have
them as substring of @style but for font names.

  It depends also if you use XSLT 1.0 or 2.0, and if you
have EXSLT support for regexp.

  In the worst case (plain XSLT 1.0 and you must to match
exactly the format of @style), you'll have to parse the
string.  For example:

    named template STYLE-MATCH-FONT-P:
      input: string
      return: boolean
      if not(string)
        return FALSE
        property <- substring-before($string, ';')
        name <- normalize-space(substring-before($property, ':'))
        if $name = 'font-familiy'
          value <- normalize-space(substring-after($property, ':'))
          if $value = $fonts
            return TRUE
            return FALSE
          STYLE-MATCH-FONT-P(substring-after($string, ';'))

  You'll have to adapt it to your precise problem: can
'font-family' appear several times in the string?, can its
value contain several font names?, etc.
