python spider如何获得输入无线电的价值

Question

html的一部分是：

<p class="more">
    <span>S</span><br />
    <input type="radio" name="rt0" value="0/0/S" onclick='showEI(this,"0", "0", "","S")'/>
    ￥1140<br />
    <span class="seatNum">>9</span>
</p>

然后我得到￥1140的xpath：

price = etree_html.find('.//*[@id="result_table"]/tbody/tr[2]/td[8]/text')
// print price

resurl是None

我能为这种情况做些什么？

Answer 1

html的部分是：

<p class="more">
    <span>S</span><br />
    <input type="radio" name="rt0" value="0/0/S" onclick='showEI(this,"0", "0", "","S")'/>
    ￥1140<br />
    <span class="seatNum">>9</span>
</p>

Answer 2

html = """<p class="more">
    <span>S</span><br />
    <input type="radio" name="rt0" value="0/0/S" onclick='showEI(this,"0", "0", "","S")'/>
    ￥1140<br />
    <span class="seatNum">>9</span>
</p>"""
import re
pattern = re.compile('<input type="radio" name="rt0".*?/>(.*?)<br />', re.DOTALL)
price = pattern.findall(html)[0].strip() #the strip command is for clearing '\n' characters and whitespaces...
print price

它有效......
