Hihave 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 $fonts. What is the xpath expression that can do
It depends. The most simple way is to use contains(). It is not the a perfect way, but it can be acceptable if the font names are complex enough and you know you'll never have them as substring of @style but for font names.
It depends also if you use XSLT 1.0 or 2.0, and if you have EXSLT support for regexp.
In the worst case (plain XSLT 1.0 and you must to match exactly the format of @style), you'll have to parse the string. For example:
named template STYLE-MATCH-FONT-P: input: string return: boolean if not(string) return FALSE else property <- substring-before($string, ';') name <- normalize-space(substring-before($property, ':')) if $name = 'font-familiy' value <- normalize-space(substring-after($property, ':')) if $value = $fonts return TRUE else return FALSE else STYLE-MATCH-FONT-P(substring-after($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.
