Re: error :"string does not uniquely describe"...

[Nigel S. <nig...@us...>]

Please send us your error.xml file.  It sounds likely that there is more
than one error node with an @id attribute of -100.  Without seeing the xml
file, then we can only guess...

Please also tell us what version of the class you are using.

Thanks,

Nigel

  Subject: error :"string does not uniquely describe"...


  hello,
  when i use an XPath object into another php class, it always print the
error : "The supplied string does not uniquely describe a node in the xml
document: " even if i'm sure that my request must give only one node since i
use an id into my xml tags.
  there is the with the getAttributes(), getData and with the getDataParts()
function too !
  it looks strange, no ?

  thank tou for your answer.

  /***************************************************************** that
works good
  require_once("XPath.class.php");

  $xpath = new XPath();

  $xpath->importFromFile("error.xml");
  $xreq = "file://error[@id='-100']";
  $attribute = $xpath->match($xreq);


  print_r($attribute."<hr>");

  print("value : ".$attribute[0]."<br>");
  print("attrib : ".$attribute["type"]."<br>");
  /*****************************************************************


  /***************************************************************** it
doesn't work !
  class toto{

  ...

    function nextError(){

        // get datas into the xml file
        file://$xreq = "file://error[@id='-100']";

        $attribute = $this->_xPathObj->getAttributes($xreq);
        $value = $this->_xPathObj->getData($xreq);

    }

  ...
  }

  the error dispayed is :
  XPath error in XPath.class.php:868 The supplied string does not uniquely
describe a node in the xml document: //error[@id='-100']
  XPath error in XPath.class.php:1117 The //error[@id='-100'] does not
evaluate to a single node in this document.
