AW: xpath getNode problem

[J. C. <jan...@im...>]

Hi

I have used PhpXpath to create an Web-based XML Editor some time ago.

This is some part of it and it might be the code you are looking for.
(especially case "UP" and case "DOWN")

Cheers
Jan

  Subject: xpath getNode problem


  Hi Nigel
  Firstly I should thank you for php.xpath. Without it I don't think I could
have done what I was trying to do.
  But there's one thing I can't quite work out -
  I have a structure like this to store notes hierarchically:

  <NOTES>
  <NOTE id="1"><HEAD>heading 1</HEAD><KIDS></KIDS></NOTE>
  <NOTE id="2"><HEAD>heading 2</HEAD><KIDS>
      <NOTE id="3"><HEAD>heading 3</HEAD><KIDS></KIDS></NOTE>
      </KIDS></NOTE>
  <NOTE id="4"><HEAD>heading 4</HEAD><KIDS></KIDS></NOTE>
  </NOTES>

  and what I'd like to do is move 'NOTE 2', along with the contents of it's
KIDS (ie 'NOTE 3') to the KIDS scope of 'NOTE 1'

  I'm assuming I'd have to store 'NOTE 2' as a variable, then delete it from
the document, then re-insert it in the new place, but I'm having problems
storing it in a variable.
  I've tried various combinations of getNode, eg:
  $note[] = $x->getNode('/NOTES[1]/NOTE[2]');
  but I must be missing something as print_r($note); is always empty

  how would you suggest I go about this?

  thankyou very much for your time
  Suzanne
