示例1: parse
/**
* Parse html into ASTs.
*
* @param {string} htmlString an HTML document.
* @param {string} href is the path of the document.
*/

contents: string, url: ResolvedUrl, urlResolver: UrlResolver,
inlineInfo?: InlineDocInfo<any>): ParsedHtmlDocument {
const ast = parseHtml(contents, {locationInfo: true});
// There should be at most one <base> tag and it must be inside <head> tag.
const baseTag = query(
ast,
p.AND(
p.parentMatches(p.hasTagName('head')),

}示例2: _attachHiddenDiv
/**
* Set the hidden div at the appropriate location within the document. The
* goal is to place the hidden div at the same place as the first html
* import. However, the div can't be placed in the `<head>` of the document
* so if first import is found in the head, we prepend the div to the body.
* If there is no body, we'll just attach the hidden div to the document at
* the end.
*/

const firstHtmlImport = dom5.query(ast, matchers.eagerHtmlImport);
const body = dom5.query(ast, matchers.body);

}

/**
* TODO(usergenic): From garlicnation's PR comment - "This matcher needs to deal
* with a number of edge cases. Whitespace-only text nodes should be ignored,
* text nodes with meaningful space should be preserved. Comments should be
* ignored if --strip-comments is set. License comments should be deduplicated
* and moved to the start of the document."
