接口 NamedNodeMap

A collection of Attr objects. Objects inside a NamedNodeMap are not in any particular order, unlike NodeList, although they may be accessed by an index as in an array.

interface NamedNodeMap {
    length: number;
    getNamedItem(qualifiedName: string): null | Attr;
    getNamedItemNS(namespace: null | string, localName: string): null | Attr;
    item(index: number): null | Attr;
    removeNamedItem(qualifiedName: string): Attr;
    removeNamedItemNS(namespace: null | string, localName: string): Attr;
    setNamedItem(attr: Attr): null | Attr;
    setNamedItemNS(attr: Attr): null | Attr;
    [index: number]: Attr;
}
