The reason is I'm just confused. :) 

Ok, so probably you mean I just have to collect the parameter(s) (with a 
XPath) and... what? From the documentation I can't find any place where I 
can insert my arguments.

Let me explain my confusion a bit: For example, you have an extension 
function foo:

  def foo(_):
    return True

As the documentation says ("What to return from a function"), you create 
an XPath evaluator, for example:

  e = etree.XPathEvaluator(doc)
  e.evaluate("foo()") 

BUT: Where do I pass my arguments? Maybe I can play with a global 
variable, but I think, that would be a bad approach.

Sorry, could you give a short example to elaborate this further, please?


Thanks,
Tom
