美丽的汤和表 [英] Beautiful Soup and Tables
问题描述
你好我想用美丽的汤解析HTML表格。
该表看起来是这样的：
Hi I'm trying to parse an html table using Beautiful Soup. The table looks something like this:
<table width=100% border=1 cellpadding=0 cellspacing=0 bgcolor=#e0e0cc>
<tr>
<td width=12% height=1 align=center valign=middle bgcolor=#e0e0cc bordercolorlight=#000000 bordercolordark=white> <b><font face="Verdana" size=1><a href="http://www.dailystocks.com/" alt="DailyStocks.com" title="Home">Home</a></font></b></td>
</tr>
</table>
<table width="100%" border="0" cellpadding="1" cellspacing="1">
<tr class="odd"><td class="left"><a href="whatever">ABX</a></td><td class="left">Barrick Gold Corp.</td><td>55.95</td><td>55.18</td><td class="up">+0.70</td><td>11040601</td><td>70.28%</td><td><center> <a href="whatever" class="bcQLink"> Q </a> <a href="chart.asp?sym=ABX&code=XDAILY" class="bcQLink"> C </a> <a href="texpert.asp?sym=ABX&code=XDAILY" class="bcQLink"> O </a> </center></td></tr>
</table>
我想获得第二个表中的信息，到目前为止，我想这code：
I would like to get the information from the second table, and so far I tried this code:
html = file("whatever.html")
soup = BeautifulSoup(html)
t = soup.find(id='table')
dat = [ map(str, row.findAll("td")) for row in t.findAll("tr") ]
这似乎没有工作，任何帮助将非常AP preciated，
谢谢
That doesnt seem to work, any help would be much appreciated, Thanks
推荐答案
第一个问题是有这样的说法：T = soup.find（ID ='表'）有什么用表的ID。我想你的意思是T = soup.find（'表'）这一发现一个表。不幸的是，只有找到的第一个的表。
The first problem is with this statement: "t=soup.find(id='table')" There is nothing with an id of table. I think what you mean is "t=soup.find('table')" this finds a table. Unfortunately it only finds the first table.
您可以做T = soup.findAll（表）[1]，但是这将是相当脆弱。
You could do "t=soup.findAll(table)[1]" but this would be quite brittle.
我建议类似如下：
html = file("whatever.html")
soup = BeautifulSoup(html)
rows = soup.findAll("tr", {'class': ['odd', 'even']})
dat = []
for row in rows:
dat.append( map( str, row.findAll('td') )
由此产生的DAT变量是：
The resulting dat variable is:
[['<td class="left"><a href="whatever">ABX</a></td>', '<td class="left">Barrick Gold Corp.</td>', '<td>55.95</td>', '<td>55.18</td>', '<td class="up">+0.70</td>', '<td>11040601</td>', '<td>70.28%</td>', '<td><center> <a href="whatever" class="bcQLink"> Q </a> <a href="chart.asp?sym=ABX&code=XDAILY" class="bcQLink"> C </a> <a href="texpert.asp?sym=ABX&code=XDAILY" class="bcQLink"> O </a> </center></td>']]
编辑：错误的数组索引
wrong array index
