The DOMAttr class

(PHP 5, PHP 7, PHP 8)

Introduction

DOMAttr represents an attribute in the DOMElement object.

Class synopsis

class DOMAttr extends DOMNode {
/* Properties */
public readonly string $name;
public readonly bool $specified = true;
public string $value;
public readonly ?DOMElement $ownerElement;
public readonly mixed $schemaTypeInfo = null;
/* Inherited properties */
public readonly string $nodeName;
public readonly int $nodeType;
public readonly ?DOMNode $parentNode;
public readonly ?DOMElement $parentElement;
public readonly DOMNodeList $childNodes;
public readonly ?DOMNode $firstChild;
public readonly ?DOMNode $lastChild;
public readonly ?DOMNode $previousSibling;
public readonly ?DOMNode $nextSibling;
public readonly ?DOMNamedNodeMap $attributes;
public readonly bool $isConnected;
public readonly ?DOMDocument $ownerDocument;
public readonly ?string $namespaceURI;
public string $prefix;
public readonly ?string $localName;
public readonly ?string $baseURI;
/* Methods */
public __construct(string $name, string $value = "")
public isId(): bool
/* Inherited methods */
public DOMNode::C14N(
    bool $exclusive = false,
    bool $withComments = false,
    ?array $xpath = null,
    ?array $nsPrefixes = null
): string|false
public DOMNode::C14NFile(
    string $uri,
    bool $exclusive = false,
    bool $withComments = false,
    ?array $xpath = null,
    ?array $nsPrefixes = null
): int|false
public DOMNode::isEqualNode(?DOMNode $otherNode): bool
public DOMNode::isSameNode(DOMNode $otherNode): bool
public DOMNode::isSupported(string $feature, string $version): bool
}

Properties

name

The name of the attribute.

ownerElement

The element which contains the attribute or null.

schemaTypeInfo

Not implemented yet, always is null.

specified

Not implemented yet, always is true.

value

The value of the attribute.

Note:

Note, XML entities are expanded upon setting a value. Thus the & character has a special meaning. Setting value to itself will fail when value contains an &. To avoid entity expansion, use DOMElement::setAttribute() instead.

Please take care on debugging DOMAttr related code. This will cause an E_WARNING that retrieving schemaTypeInfo attribute is not implemented yet. An IDE like Eclipse will inspect the object and its member elements. In conjunction with registered error handlers, which will translate the E_WARNING into Exception your debugging session will end unexpectedly. This has caused me some trouble while debugging my PHPUnit test case in eclipse using "Makegood" plugin.

A possible workarround is to deactivate the error handling during debugging using error_reporting(0). Remove the statement after finishing your debugging session.

See also the properties from the inherited class DOMNode ( http://php.net/manual/en/class.domnode.php ), eg. namespaceURI, prefix, localName, etc, especially if you have to deal with namespaced attributes
