DOMDocument::createElement — Create new element node
public DOMDocument::createElement ( string $name [, string $value ] ) : DOMElement
This function creates a new instance of class DOMElement. This node will not show up in the document unless it is inserted with (e.g.) DOMNode::appendChild().
name
The tag name of the element.
value
The value of the element. By default, an empty element will be created. The value can also be set later with DOMElement::$nodeValue.
The value is used verbatim except that the < and > entity references will escaped. Note that & has to be manually escaped; otherwise it is regarded as starting an entity reference. Also " won't be escaped.
Returns a new instance of class DOMElement or false if an error occurred.
DOM_INVALID_CHARACTER_ERR
Raised if name contains an invalid character.
Example #1 Creating a new element and inserting it as root
<?php
$dom = new DOMDocument('1.0', 'utf-8');
$element = $dom->createElement('test', 'This is the root element!');
// We insert the new element as root (child of the document)
$dom->appendChild($element);
echo $dom->saveXML();
?> The above example will output:
<?xml version="1.0" encoding="utf-8"?> <test>This is the root element!</test>
Example #2 Passing text containing an unescaped & as value
<?php
$dom = new DOMDocument('1.0', 'utf-8');
$element = $dom->createElement('foo', 'me & you');
$dom->appendChild($element);
echo $dom->saveXML();
?> The above example will output something similar to:
Warning: DOMDocument::createElement(): unterminated entity reference you in /in/BjTCg on line 4 <?xml version="1.0" encoding="utf-8"?> <foo/>
Note:
The
valuewill not be escaped. Use DOMDocument::createTextNode() to create a text node with escaping support.
