示例1: parseHtml
export function parseHtml(html: string): Node {
let parser = new parse5.Parser(_ADAPTER);
let root = parser.parse(html);
// Normally, "root" is the document node and contains the optional doctype
// node and the HTML node as children. We'll skip the doctype node and
// return the only HTML node.
let element:Node = null;
for (let child of _ADAPTER.getChildNodes(root)) {
if (!_ADAPTER.isDocumentTypeNode(child)) {
if (element !== null) {
throw Error("Found more than one element at the root level while parsing HTML text");
