XPath :( html sign) (fast reaction)

eg:

<html xmlns=http://www.w3.org/1999/xhtml> <head> <meta charset=utf-8> <meta name=referrer content=always> <meta http-equiv=X-UA-Compatible content="IE=edge,chrome=1"> <meta name=viewport content="width=device-width,initial-scale=1.0,minimum-scale=1.0,maximum-scale=1.0,user-scalable=no"> <title>专家析云南“火流星”空爆事件：不能算“行星撞地球”</title> <link rel=stylesheet type=text/css href="https://ss0.bdstatic.com/5aV1bjqh_Q23odCf/static/superlanding/css/landing_min_6b5661eb.css"> </head> <body> <script>
  /* eslint-disable */

/html/head/title/text()
