我想得到日期和州（在“Fecha”和“Estado”下）。该表中可能有更多的td标签

结果示例

2015年2月24日 - Despachado a Sucursal de Destino - Planta Velez Sarfield
25/2/2015 - EnTránsitoaSuc。 de Destino - ROSARIO
到目前为止我做了什么：
URL = 'https://www1.oca.com.ar/OEPTrackingWeb/detalleenviore.asp?numero=4463400000000000255'
r = requests.get(URL, headers={'User-Agent': 'User-Agent'})
s = bs4.BeautifulSoup(r.text)
print s.body.table.table.next_sibling.next_sibling
答案 0 :(得分：2)
我会查找列标签，然后从那里取出：
import re
header = s.find('b', text=re.compile('fecha', flags=re.I))
parent_row = header.find_parent('tr')
for row in parent_row.find_next_siblings('tr'):
cells = row.find_all('td', class_='texto')
date, entry = (c.get_text(strip=True) for c in cells)
获得标头后，代码将遍历到最近的<tr>行并迭代所有后续表行。带有文本的单元格有一个有用的texto类;在这些元素上使用Element.get_text()（使用strip=True删除这些单元格中的额外空格）会为我们提供您所需的信息。
对于您的示例网址，这会产生：
>>> import requests
>>> import bs4
>>> import re
>>> URL = 'https://www1.oca.com.ar/OEPTrackingWeb/detalleenviore.asp?numero=4463400000000000255'
>>> r = requests.get(URL, headers={'User-Agent': 'User-Agent'})
>>> s = bs4.BeautifulSoup(r.text)
>>> header = s.find('b', text=re.compile('fecha', flags=re.I))
>>> parent_row = header.find_parent('tr')
>>> for row in parent_row.find_next_siblings('tr'):
... cells = row.find_all('td', class_='texto')
... date, entry = (c.get_text(strip=True) for c in cells)
... print(date, entry)
...
