  • DOMElement::__construct()

    (PHP 5, PHP 7)

    Creates a new DOMElement object

    说明

    publicDOMElement::__construct(string $name[,string $value[,string $namespaceURI]])

    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

    $name

    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.

    $namespaceURI

    A namespace URI to create the element within a specific namespace.

    范例

    Example #1 Creating a new DOMElement

    <?php
    $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 $value argument with htmlspecialchars.
    See: http://bugs.php.net/bug.php?id=31191
    If you like to view an element simply do:
    <?php
    echo htmlentities($element->C14N());
    ?>
    Undocumented but found ;)
    Remember, Dom-Nodes mustn't start with a number:
    allowed:
    <t12345t4>Value</t12345t4>
    Not allowed:
    <12345t4>VALUE</12345t4>
