Question

如何在表格中解析一个简单的网络抓取应用程序？

我的流程是：

创建网址的汤对象
使用
在已找到的表格中找到标签
找到行
找到标题
在表格中找到数据

HTML code：

<table border="0" cellpadding="2" cellspacing="1" width="660">

我想获取最后一行中的所有数据（

这是我到目前为止所做的：

  try:
    resp = urlopen(url)
  except URLError as e:
    print "An error occured fetching %s \n %s" %  (url, e.reason)
    return 1
  soup = BeautifulSoup(resp.read(), 'lxml')

  # get outer table
  try:
    outerTables = soup.findAll('table')
  except AttributeError as e:
    print "No tables found, exciting"
    return 1

  # get inner table
  try:
    for table in outerTables:
      innerTables = soup.findAll('table')
  except AttributeError as e:
    print "No inner tables found"
    return 1

  # get rows
  try:
    for table in innerTables:
      rows = soup.findAll('tr')
  except AttributeError as e:
    print "No rows found"
    return 1

  # get headers
  headers = []
  try:
    for row in rows:
      markup = soup.findAll('th')
  except AttributeError as e:
    print "No headers found"
    return 1
  for i in range(0,len(markup)):
    headers.append(markup[i].string)

我在正确的道路上吗？

Answer 1

你的html有一个带有标题的表，它是 th 标记，有些行是 tr 标记，行内是你想要的数据 > td 标签：

h = """<table border="0" cellpadding="2" cellspacing="1" width="660">
      <tr bgcolor="#CCCCCC">
        <th class="IntWxHeader">Time</th>
        <th class="IntWxHeader">Weather</th>
        <th class="IntWxHeader">Temperature</th>
        <th class="IntWxHeader">Dewpoint</th>
        <th class="IntWxHeader">Humidity</th>
