I am trying to evaluate something like this: 

substring(concat('$',substring-after(substring(concat(substring-after(//div[@class='current'],'Now:'),substring-before(//a[@rel='accordion'],' ')),number(contains(//a[@rel='accordion'],'$'))*6),'$')),number(not(contains(substring-after(//div[@class='current'],'Now:'),'$')))+1)

But it always fails. Where can I find the list of supported functions by your library?
