Scraper Class with Regex

Question

I already posted a not (yet) complete version of this class, but that question got closed, because it contained not passing tests. Here is the full version, all 5 tests pass.

Originally there was only processPlayer when I found a very rare case (see the last test Special case). The method player is a patch to handle this kind of cases. Maybe the two method could be merged.

class Scraper {
  /**
   * Converts a html string to a cheerio object
   * @param {String} html The html string
   * @return {Object} The cheerio object
   */
  htmlToDom(html) {
    return cheerio.load(html)
  }

  // http://jsbin.com/nojedozaxo/1/edit?js,console,output
  player(href, name) {
    let p = name.replace(/\./g, '.+')
    let r = new RegExp(".+(" + p + ")-.+", 'i')
    let R = href.match(r)[1].split('-')
      .map(w => w.charAt(0).toUpperCase() + w.slice(1))
    return {
      firstName: R[2],
      lastName: R.slice(0, 2).join('-')
    }
  }

  processPlayers(players) {
    // is it a selector function or an object
    players = typeof players === 'function' ? players('a') : players.find('a')
    let href = players.attr('href')
    let N = players.text().trim().split(/\s+-\s+/).map(n => {
      if (n.indexOf(' ') === -1) {
        return this.player(href, n)
      }
      let r = new RegExp('.+(' + n.replace(/-/g, '\\S+').replace(/\./g, '[^-]+').replace(/\s/g, '.') + ').+', 'i')
      let p = {
        lastName: n.replace(/\s\S+\./g, '')
      }
      href.match(r).map(m => {
        r = new RegExp(p.lastName.replace(/\s/g, '.') + '-', 'i')
        m = m.replace(r, '').split(/-/).map(i => {
          return i.substring(0, 1).toUpperCase() + i.substring(1)
        })
        p.firstName = n.split(p.lastName + ' ')[1].replace(/[a-z]*\./g, '').split('').map(l => {
          return m[0] && m[0].indexOf(l) === 0 ? m.shift() : l
        }).join('')
      })
      return p
    })
    return {
      p1: N[0],
      p2: N[1]
    }
  }
}
