打印特定行(Beautifulsoup)

li = soup.prettify().split('\n')
print str(li[line_number-1])

不要使用漂亮的打印来尝试和解析tds,具体选择标记,如果属性是唯一的,则使用它;如果类名是唯一的则使用它:

td = soup.select_one("td.content")
td = soup.select_one("td[colspan=3]")

如果是第四个td:

td = soup.select_one("td:nth-of-type(4)")

如果它在特定的表中,那么选择该表,然后在表中找到td,尝试将html拆分为行,索引实际上比使用 regex to parse html .

您可以使用td前面的粗体标记中的文本来获取特定td,即 财政部建筑分类: :

In [19]: from bs4 import BeautifulSoup

In [20]: import urllib.request

In [21]: url = "http://a810-bisweb.nyc.gov/bisweb/PropertyProfileOverviewServlet?boro=1&houseno=1&street=park+ave&go2=+GO+&requestid=0"

In [22]: r = urllib.request.urlopen(url).read()

In [23]: soup = BeautifulSoup(r, "html.parser")

In [24]: print(soup.find("b",text="Department of Finance Building Classification:").find_next("td").text)
O6-OFFICE BUILDINGS

选择第n个表和行:

In [25]: print(soup.select_one("table:nth-of-type(8) tr:nth-of-type(5) td[colspan=3]").text)
O6-OFFICE BUILDINGS
