When you call the selectNodes method, you get in return a list of nodes. item(0) refers to the first element of the list (which will be .NULL., in case of a list of length zero), and item(0).text refers to the textual contents of the element (that may even be a complex element, comprising a segment of the XML tree and various sub-elements).

>Could you post a very, very smal example about using : verify the length of a node selection.

m.nodelist = m.OROOT.selectNodes("Documento/dataobra")
IF m.nodelist.length == 0
  *  the element does not exist
  * deal with it
ELSE
  * get the value from the first element of the list of selected nodes 
  m.dataobra = m.nodelist.item(0).text
ENDIF

(of course, you may define a function to ease the repetition of the construction).

Hope it helps!

Hi António,
