Hi guys,

        I have a doubt about testing preceding-sibling processing-instruction.
        I have this xml:

       <root>
           <child1>
                   child 1
           </child1>
           <?proc?>
           <child2>
                  child 2
          </child2>
     </root>

           And I need to know if child2 has the first
preceding-sibling as a processing-instruction. In this case it should
return true.

If whitespace text nodes matter then in your sample
  /root/child2/preceding-sibling::node()[1]
is a text node and only
  /root/child2/preceding-sibling::node()[2]
is a processing instruction node.

I tryed something like this

preceding-sibling::*[1]/name()|preceding-sibling()[1]/name = 'proc'
