The XMLReader::getAttribute() function is an inbuilt function in PHP which is used to get the value of a named attribute.
Syntax:
string XMLReader::getAttribute( string $name )
Parameters: This function accepts a single parameter $name which holds the name of the attribute.
Return Value: This function returns the value of the attribute, or NULL if no attribute with the given name is found or not positioned on an element node.
Below examples illustrate the XMLReader::getAttribute() function in PHP:
Example 1:
data.xml
<?xml version="1.0" encoding="utf-8"?>
<body>
<h1> Hello </h1>
</body>
|
index.php
<?php
$XMLReader = new XMLReader();
$XMLReader->open('data.xml');
while ($XMLReader->read()) {
if ($XMLReader->nodeType == XMLREADER::ELEMENT) {
$value = $XMLReader->getAttribute('id');
echo $value;
}
}
?>
|
Output:
// Empty string because there is no attributes with name id
Program 2:
data.xml
<?xml version="1.0" encoding="utf-8"?>
<body>
<h1 id="geeksforgeeks"> Hello </h1>
<h2 id="my_id"> World </h2>

$XMLReader = new XMLReader();
$XMLReader->open('data.xml');
while ($XMLReader->read()) {
if ($XMLReader->nodeType == XMLREADER::ELEMENT) {
$value = $XMLReader->getAttribute('id');
echo $value . "<br>";
}
}
