将HTML表转换为JSON

Question

我正在尝试将我通过BeautifulSoup提取的表转换为JSON.

到目前为止,我已设法隔离所有行,但我不确定如何使用此处的数据.任何建议将非常感谢.

[<tr><td><strong>Balance</strong></td><td><strong>$18.30</strong></td></tr>, 
<tr><td>Card name</td><td>Name</td></tr>, 
<tr><td>Account holder</td><td>NAME</td></tr>, 
<tr><td>Card number</td><td>1234</td></tr>, 
<tr><td>Status</td><td>Active</td></tr>]

(为了便于阅读,我打破了线路)

这是我的尝试:

result = []
allrows = table.tbody.findAll('tr')
for row in allrows:
    result.append([])
    allcols = row.findAll('td')
    for col in allcols:
        thestrings = [unicode(s) for s in col.findAll(text=True)]
        thetext = ''.join(thestrings)
        result[-1].append(thetext)

这给了我以下结果:

[
 [u'Card balance', u'$18.30'],
 [u'Card name', u'NAMEn'],
 [u'Account holder', u'NAME'],
 [u'Card number', u'1234'],
 [u'Status', u'Active']
]

可能你的数据是这样的:

html_data = """
<table>
  <tr>
    <td>Card balance</td>
    <td>$18.30</td>
  </tr>
  <tr>
    <td>Card name</td>
    <td>NAMEn</td>
  </tr>
  <tr>
    <td>Account holder</td>
    <td>NAME</td>
  </tr>
  <tr>
    <td>Card number</td>
    <td>1234</td>
  </tr>
  <tr>
    <td>Status</td>
    <td>Active</td>
  </tr>
</table>
"""

我们可以使用以下代码将结果作为列表获取:

from bs4 import BeautifulSoup
table_data = [[cell.text for cell in row("td")]
                         for row in BeautifulSoup(html_data)("tr")]

要将结果转换为JSON,如果您不关心订单:

import json
print json.dumps(dict(table_data))

结果:

{
    "Status": "Active",
    "Card name": "NAMEn",
    "Account holder":
    "NAME", "Card number": "1234",
    "Card balance": "$18.30"
}

如果您需要相同的订单,请使用以下命令:

from collections import OrderedDict
import json
print json.dumps(OrderedDict(table_data))

哪个给你:

{
    "Card balance": "$18.30",
    "Card name": "NAMEn",
    "Account holder": "NAME",
    "Card number": "1234",
    "Status": "Active"
}
