The DOMElement::setAttribute() function is an inbuilt function in PHP which is used to set an attribute with given name to the given value. If the attribute does not exist, it will be created.
Syntax:
DOMAttr DOMElement::setAttribute( string $name, string $value )
Parameters: This function accepts two parameters as mentioned above and described below:
- $name: It specifies the name of attribute.
- $value: It specifies the value of attribute.
Return Value: This function returns DOMAttr on success or FALSE on error.
Exceptions: This function throws DOM_NO_MODIFICATION_ALLOWED_ERR, if the node is readonly.
Below given programs illustrate the DOMElement::setAttribute() function in PHP:
Program 1:
<?php
$dom = new DOMDocument();
$node = $dom->createElement("p",
'Hello, this is my paragraph.');
$newnode = $dom->appendChild($node);
$newnode->setAttribute("style", "color:red");
echo $dom->saveXML();
?>
|
Output:
<?xml version="1.0"?>
<p style="color:red">Hello, this is my paragraph.</p>
Program 2:
<?php
$dom = new DOMDocument();
$dom->loadXML("<?xml version=\"1.0\"?>
<root>
<html>
<h1 id=\"my_id\"> Geeksforgeeks </h1>
<h2> Second heading </h2>
</html>
</root>");
$node = $dom->getElementsByTagName('h1')[0];
echo "Before the addition of attributes: <br>";
$attributeCount = $node->attributes->count();
echo 'No of attributes => ' . $attributeCount;
$node->setAttribute('new', 'value');
echo "<br>After the addition of attributes: <br>";
$attributeCount = $node->attributes->count();
echo 'No of attributes => ' . $attributeCount;
?>
|
