DOMDocument->createElement()

(no version information, might be only in CVS)

DOMDocument->createElement() -- Create new element node

说明

class DOMDocument {

DOMElement createElement ( string name [, string value] )

}

This function creates a new instance of class DOMElement . 本节点不会出现在文档中，除非是用例如 DOMNode->appendChild() 函数来将其插入。

参数

name: The tag name of the element.
value: The value of the element. By default, an empty element will be created. You can also set the value later with DOMElement->nodeValue.

返回值

Returns a new instance of class DOMElement or FALSE if an error occured.

异常

DOM_INVALID_CHARACTER_ERR: Raised if name contains an invalid character.

范例

例子 1. Creating a new element and inserting it as root

<?php $dom = new DOMDocument ( '1.0' , 'iso-8859-1' ); $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 (); ?>

上例将输出：

<?xml version="1.0" encoding="iso-8859-1"?> <test>This is the root element!</test>
