XML php dom

How do u return a single node value from a xml documnet using php.

Javascript code for Windows server : WORKS OK
xmldoc = new ActiveXObject("Microsoft.XMLDOM");

xmldoc.async = false;

xmldoc.load("../xml/data.xml");

if(xmldoc.parseError.errorCode != 0){

window.location.replace("../error.shtml");}

else{

nodes = xmldoc.documentElement.childNodes;

var maxl = xmldoc.documentElement.childNodes.length-1;

calc.namevalue.value = xmldoc.selectSingleNode("//VALUE").text;

PHP DOES NOT RETURN VALUE JUST THE WORD ARRAY IN THE TEXT BOX- my lack of understanding here is very low, can anyone assit in the proper syntax????

<?php
session_start();
if(!$dom = domxml_open_file("../xml/data.xml")) {
echo "Error while parsing the document\n";
exit;
}
$root = $dom->document_element();
$xml_value = $root->get_elements_by_tagname("VALUE");
?>

I can't answer your question based on the XML commands you are using, but I can recommend use of http://sourceforge.net/projects/phpxpath/. I used it myself and it worked like a charm. And you are not limited to windows or some installed activex.

Simply include the phpxpath class and use it like this:

PHP Code:



require_once "../include/XPath.class.php"; 
 
$xpath = new XPath(); 
 
if( !$xpath->importFromFile( "somefile.xml" ) ) 
{ 
   die(); 
}

To retrieve a list of all matching elements call

PHP Code:



$List = $xpath->match( "/path/to/elements/allofthem/" ); 
   
  foreach( $List as $One )

The value can be retrieved by:

PHP Code:



 
echo $xpath->getData( "/family/dad/name" )

thank you - seams nice however documentation is rather low -

can you point me to some examples ie reading in arrays::

<?php
require_once( "extras/XPath.class.php" );
$file=("xmldata/data.xml");
$x = new XPath($file);
//$fut_exp_value = array();
$eyci_value = $x->getData("/TLEF/EYCI/VALUE");
$fut_exp1 = $x->getData("/TLEF/FUTURES/EXPIRE[1]");

?>
<html>
<title>Edit an XML Article</title>
<body>
<input name="name" type="text" id="name" value="<?php echo $eyci_value ?>" size="30">
</body>
</html>

cant work out how to display array data from the xml document at all, EXPIRE is in the document 9 times, how do you read each one in????
