$dom->get_elements_by_tagname('employee')->item(0);

Hello all,

I would greatly appreciate suggestions on my following PHP4 problem:

In PHP5 this works:
$employee = $dom->getElementsByTagName('employee')->item(0);

In PHP4 this doesn't work:
$employee = $dom->get_elements_by_tagname('employee')->item(0);

I am trying to travese a XML DOM to replace a textnode.
It works in PHP5 but not in PHP4 because of the "->item(0)" part

The error message thrown in PHP4 is:
Parse error: parse error, unexpected T_OBJECT_OPERATOR in line 25

any suggestions would be greatly appreciated.

Complete PHP4 code is:

Expand|Select|Wrap|Line Numbers

 
<?php
 
function result($dom)

{

echo "<HTML>";

echo "<Head>";

echo "<title>Example of DOMNode->replaceChild</title>";

echo "<Head>";

echo "<body>";

echo "<PRE>";

echo htmlentities($dom->dump_mem(true));

echo "</PRE>";

echo "</body>";

echo "</HTML>";

}
 
// Load the XML source

$dom = domxml_open_file("test.xml");
 
result($dom);
 
//retrieve the first element with name employee

$employee = $dom->get_elements_by_tagname('employee')->item(0);
 
//retrieve the first element with name employeeaddress

$employeeaddress = $dom->get_elements_by_tagname('employeeaddress')->item(0);
 
//create a new element

$newChild = $dom->create_element('newNode');
 
//create a text node

$textNode = $dom->create_text_node('newNode');
 
//append the text to the  newly created element

$newChild->append_child($textNode);
 
//replace the employeeaddress element by newly created element

$employee->replace_child($newChild,$employeeaddress);
 
result($dom);
 
?>

The XML file is (test.xml):

Expand|Select|Wrap|Line Numbers

 
<?xml version="1.0" encoding="UTF-8"?>

<employee>

<employeename id="myId">test1</employeename>

<employeeaddress>testAddress1</employeeaddress>

<SSN>11111</SSN>

<company>XYZ Corporation</company>

</employee>

Found the solution, sorry for the inconvenience. Perhaps it helps someone:

PHP4 code should be:

Expand|Select|Wrap|Line Numbers

 
//retrieve the first element with name employee

$root = $dom->document_element();
 
//retrieve the first element with name employeeaddress

$employeeaddress = $dom->get_elements_by_tagname('employeeaddress');
 
//create a new element

$newChild = $dom->create_element('newNode');
 
//create a text node

$textNode = $dom->create_text_node('newNode');
 
//append the text to the  newly created element

$newChild->append_child($textNode);
 
//replace the employeeaddress element by newly created element

$root->replace_child($newChild,$employeeaddress[0]);

regards
