Re: [xsl] filter using contains with multiple values

YESS! This (tokenising with in the XSL) was the final idea to solve this 
puzzling problem! I was to lazy to try out the String[], since this would also 
leave me with
tokenising the argument within the servlet (and I like the simple and clean 
intermediate step to tokenise in the XSL!)
Thank you very much Martin (but also thanks to all contributors)!

As final wrap up to make this thread useful to the public:

Be careful with how the transformers handle complex input if passing in as 
external parameters (and Graydon, I tried using different quotation, it did not 
help!)!
Here one really has to consult the documentation of THAT specific transformer 
in full detail on how the setParameter’s second argument is going to be handled!

So one could think of passing them using:

                       transformer.setParameter("filter_values", “Log, 
Info”);

(which does not work either) but here I guess the whole second argument is 
interpreted as one single string (object) and I knew in advance that this is 
not meant to be working!

If JAXP does not allow you to pass in a sequence of strings then the easiest 
way around that might be to pass in the string you have above and use a 
second variable

  <xsl:variable name="filter-seq" select="tokenize($filter_values, ',\s*')"/>

then within your comparison you can use that $filter-seq.

As far as I understand 
http://saxonica.com/documentation9.5/extensibility/function-result.html and 
http://saxonica.com/documentation9.5/using-xsl/embedding/jaxp-transformation.html
 you could also try to pass a Java String[] as the parameter value, it should 
then be treated as a sequence of strings in XSLT/XPath. That is the 9.5 
documentation however, I don't know whether 9.1 is different.
