     stringStream.pipe(htmlParser)
     const collector = new Collector()
     htmlParser.on('data', str => collector.write(str))
     stringStream.read()
     return collector.data.map(data => JSON.parse(data))
  },

    const tokens = this.parse(html)
    return isMatched(tokens)
  },
  buildDOMTree(html) {
    const tokens = this.parse(html)
