美汤:获取特定桌子的内容

这不是您所需要的特定代码,只是一个关于如何使用BeautifulSoup的演示。它查找ID为“table1”的表,并获取其所有tr元素。

html = urllib2.urlopen(url).read()
bs = BeautifulSoup(html)
table = bs.find(lambda tag: tag.name=='table' and tag.has_attr('id') and tag['id']=="Table1") 
rows = table.findAll(lambda tag: tag.name=='tr')

soup = BeautifulSoup(HTML)

# the first argument to find tells it what tag to search for
# the second you can pass a dict of attr->value pairs to filter
# results that match the first tag
table = soup.find( "table", {"title":"TheTitle"} )

rows=list()
for row in table.findAll("tr"):
   rows.append(row)

# now rows contains each tr in the table (as a BeautifulSoup object)
# and you can search them to pull out the times

如果你在意的话,美丽的汤就不再被维护了,原始的维护者建议向LXML过渡。xpath应该做得很好。
