美丽的汤循环通过网址并显示数据

Question

我正在使用 Beautiful soup 来抓取此网址 http://www.gbgb.org.uk/resultsRace.aspx?id=1839041 它可以很好地根据需要显示所有字段。但是它只在夹具结果卡上显示一场比赛，我想提取整个比赛会议，卡上的比赛在 9 到 14 场之间变化 这是整个会议的 URL http://www.gbgb.org.uk/resultsMeeting.aspx?id=135488。 有什么方法可以让我循环遍历完整的比赛卡片并在卡片上显示所有比赛的内容。下面是一场比赛的代码。

 from urllib import urlopen

from bs4 import BeautifulSoup
html = urlopen("http://www.gbgb.org.uk/resultsRace.aspx?id=1839041")

bsObj = BeautifulSoup(html)
nameList = bsObj. findAll("div", {"class": "track"})
for name in nameList:
 print(name. get_text())

nameList = bsObj. findAll("div", {"class": "date"})
for name in nameList:
 print(name. get_text())

nameList = bsObj. findAll("div", {"class": "datetime"})
for name in nameList:
 print(name. get_text())
nameList = bsObj. findAll("div", {"class": "grade"})
for name in nameList:
 print(name. get_text())
nameList = bsObj. findAll("div", {"class": "distance"})
for name in nameList:
 print(name. get_text())
nameList = bsObj. findAll("div", {"class": "prizes"})
for name in nameList:
 print(name. get_text())
nameList = bsObj. findAll("li", {"class": "first essential fin"}) 
for name in nameList:
 print(name. get_text())
nameList = bsObj. findAll("li", {"class": "essential greyhound"})
for name in nameList:
 print(name. get_text())
nameList = bsObj. findAll("li", {"class": "trap"})
for name in nameList:
 print(name. get_text())
nameList = bsObj. findAll("li", {"class": "sp"})
for name in nameList:
 print(name. get_text())
nameList = bsObj. findAll("li", {"class": "timeSec"})
for name in nameList:
 print(name. get_text())
nameList = bsObj. findAll("li", {"class": "timeDistance"})
for name in nameList:
 print(name. get_text())
nameList = bsObj. findAll("li", {"class": "essential trainer"})
for name in nameList:
 print(name. get_text())
nameList = bsObj. findAll("li", {"class": "first essential comment"})
for name in nameList:
 print(name. get_text())
nameList = bsObj. findAll("div", {"class": "resultsBlockFooter"})
for name in nameList:
 print(name. get_text())

您只需要遍历结果块。标签略有不同，但本质上是一样的。我在 Chrome 中使用检查元素功能，使 HTML 抓取变得容易。

from urllib import urlopen

from bs4 import BeautifulSoup
baseURL = 'http://www.gbgb.org.uk/resultsMeeting.aspx?id=135488'
html = urlopen(baseURL)
bsObj = BeautifulSoup(html, 'lxml')
nameList = bsObj.findAll("div", {"class": "resultsBlock"})
for i in nameList:
    # just the trap info, the rest is similar
    nameList2 = i.findAll("li", {"class": "trap"})
    for j in nameList2:
        print(j.get_text())
