Re: xpath question

newline char xpath
  what is the difference between these xpaths:
  //table/tgroup/tbody/row[1]/entry[1]/child::node()[1]
  and
  //table/tgroup/tbody/row[1]/entry[1]/ce[1]
  //table/tgroup/tbody/row[1]/entry[1]/para[1]


node() matches all kinds of nodes so child::node()[1] which is
the same as node()[1] matches the first node which, in your case is a
text node consisting of a single newline character.

You want
*[1]
which will select the first element node.

(Try to avoid // if you can, it os a very expensive operation)

David
