- <code class="language-text">//span[@class="pro-title"]/text()
- </code>
(?<=>).*?(?=<)
如果实际情况中有许多不同的“<>”对，就请自行填充前后向断言的内容
你应该看看汉字编码，网页的编码很可能是GBK,然而python是用的utf8，所以绝对匹配不了
- <code class="language-text">---------------代码区----------------
- # coding:utf-8
- import re
- x='<span class="pro-title">Apple iPhone 5s (A1530) 16GB 金色 移动联通4G手机</span> <span class="pro-price">'
- xre=r'(<span class="pro-title">)(.+)(</span> <span class="pro-price">)'
- z=re.search(xre,x).group(2)
- print z
- ----------</span></span></code>

一般情况下可以这样匹配中文，如图：
- <code class="language-python3"><span class="kn">import</span> <span class="nn">re</span>
