BeautifulSoup HTML 表格解析
我正在尝试从这个网站提取信息(HTML表格):http://www.511virginia.org/RoadConditions.aspx?j=All&r=1
目前我在使用BeautifulSoup,下面是我的代码:
from mechanize import Browser
from BeautifulSoup import BeautifulSoup
mech = Browser()
url = "http://www.511virginia.org/RoadConditions.aspx?j=All&r=1"
page = mech.open(url)
html = page.read()
soup = BeautifulSoup(html)
table = soup.find("table")
rows = table.findAll('tr')[3]
cols = rows.findAll('td')
roadtype = cols[0].string
start = cols.[1].string
end = cols[2].string
condition = cols[3].string
reason = cols[4].string
update = cols[5].string
entry = (roadtype, start, end, condition, reason, update)
print entry
问题出在开始和结束的列上。它们的输出结果都是“None”。
输出结果:
(u'Rt. 613N (Giles County)', None, None, u'Moderate', u'snow or ice', u'01/13/2010 10:50 AM')
我知道它们被存储在列的列表中,但似乎多出来的链接标签搞乱了原始HTML的解析,原始HTML看起来是这样的:
<td headers="road-type" class="ConditionsCellText">Rt. 613N (Giles County)</td>
<td headers="start" class="ConditionsCellText"><a href="conditions.aspx?lat=37.43036753&long=-80.51118005#viewmap">Big Stony Ck Rd; Rt. 635E/W (Giles County)</a></td>
<td headers="end" class="ConditionsCellText"><a href="conditions.aspx?lat=37.43036753&long=-80.51118005#viewmap">Cabin Ln; Rocky Mount Rd; Rt. 721E/W (Giles County)</a></td>
<td headers="condition" class="ConditionsCellText">Moderate</td>
<td headers="reason" class="ConditionsCellText">snow or ice</td>
<td headers="update" class="ConditionsCellText">01/13/2010 10:50 AM</td>
所以应该打印的内容是:
(u'Rt. 613N (Giles County)', u'Big Stony Ck Rd; Rt. 635E/W (Giles County)', u'Cabin Ln; Rocky Mount Rd; Rt. 721E/W (Giles County)', u'Moderate', u'snow or ice', u'01/13/2010 10:50 AM')
任何建议或帮助都非常感谢,提前谢谢大家。

start = cols[1].find('a').string
或者更简单
start = cols[1].a.string
或者更好
start = str(cols[1].find(text=True))
和
entry = [str(x) for x in cols.findAll(text=True)]
