DOMElement::__construct — Creates a new DOMElement object

说明

public DOMElement::__construct(string $qualifiedName, ?string $value = null, string $namespace = "")

Creates a new DOMElement object. This object is read only. It may be appended to a document, but additional nodes may not be appended to this node until the node is associated with a document. To create a writeable node, use DOMDocument::createElement or DOMDocument::createElementNS.

参数

qualifiedName: The tag name of the element. When also passing in namespaceURI, the element name may take a prefix to be associated with the URI.
value: The value of the element.
namespace: A namespace URI to create the element within a specific namespace.

$dom = new DOMDocument('1.0', 'iso-8859-1');
$element = $dom->appendChild(new DOMElement('root'));
$element_ns = new DOMElement('pr:node1', 'thisvalue', 'http://xyz');
$element->appendChild($element_ns);
echo $dom->saveXML(); /* <?xml version="1.0" encoding="utf-8"?>
<root><pr:node1 xmlns:pr="http://xyz">thisvalue</pr:node1></root> */

Note that this function is buggy. You have to manually escape the $value argument with htmlspecialchars.

If you like to view an element simply do:


<?php

echo htmlentities($element->C14N());

?>



Undocumented but found ;)

Remember, Dom-Nodes mustn't start with a number:

allowed:
<t12345t4>Value</t12345t4>

Not allowed:
<12345t4>VALUE</12345t4>
