    DOMAttr クラス

    (PHP 5, PHP 7, PHP 8)

    はじめに

    DOMNode を継承します。DOMAttr は、DOMElement オブジェクトの属性を表します。

    クラス概要

    class DOMAttr extends DOMNode {
    /* プロパティ */
    public readonly string $name;
    public readonly bool $specified = true;
    public string $value;
    public readonly ?DOMElement $ownerElement;
    public readonly mixed $schemaTypeInfo = null;
    /* 継承したプロパティ */
    public readonly string $nodeName;
    public ?string $nodeValue;
    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;
    public string $textContent;
    /* メソッド */
    public __construct(string $name, string $value = "")
    public isId(): bool
    /* 継承したメソッド */
    public DOMNode::appendChild(DOMNode $node): DOMNode|false
    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::cloneNode(bool $deep = false): DOMNode|false
    public DOMNode::compareDocumentPosition(DOMNode $other): int
    public DOMNode::contains(DOMNode|DOMNameSpaceNode|null $other): bool
    public DOMNode::getLineNo(): int
    public DOMNode::getNodePath(): ?string
    public DOMNode::getRootNode(?array $options = null): DOMNode
    public DOMNode::hasAttributes(): bool
    public DOMNode::hasChildNodes(): bool
    public DOMNode::insertBefore(DOMNode $node, ?DOMNode $child = null): DOMNode|false
    public DOMNode::isDefaultNamespace(string $namespace): bool
    public DOMNode::isEqualNode(?DOMNode $otherNode): bool
    public DOMNode::isSameNode(DOMNode $otherNode): bool
    public DOMNode::isSupported(string $feature, string $version): bool
    public DOMNode::lookupNamespaceURI(?string $prefix): ?string
    public DOMNode::lookupPrefix(string $namespace): ?string
    public DOMNode::normalize(): void
    public DOMNode::removeChild(DOMNode $child): DOMNode|false
    public DOMNode::replaceChild(DOMNode $node, DOMNode $child): DOMNode|false
    public DOMNode::__sleep(): array
    public DOMNode::__wakeup(): void
    }

    プロパティ

    name

    属性の名前

    ownerElement

    属性を保持する要素。存在しない場合は null になります。

    schemaTypeInfo

    未実装です。常に null を返します。

    specified

    未実装です。常に true を返します。

    value

    属性の値

    注意:

    値を設定する際には、XML のエンティティが展開されるので注意してください。 つまり、& 文字は特別な意味を持ちます。 value に & が含まれている場合、それを直接設定すると処理が失敗します。 エンティティの展開を避けるためには、 DOMElement::setAttribute() を代わりに使います。

    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
