我正在尝试从此网站解析信息(HTML表格):http://www.511virginia.org/RoadConditions.aspx?j=All&r=1
目前我正在使用BeautifulSoup,我的代码如下:
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
问题出在起始列和结束列上。它们只会输出为"None"。
输出:
(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列表中,但似乎额外的链接标签会使原始HTML解析出现问题,原始HTML如下:
<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')
非常感谢您的帮助和建议,非常期待您的回复。
