Question

How to get these values with BeautifulSoup?

Answer 1

A:

I know using HTQL, it is simple:

<tr>.<td>2,4

--

HTQL only has COM support thought. Here is a complete example in javascript:

<html>
<body>
<script language=JavaScript>
     var a= new ActiveXObject("HtqlCom.HtqlControl");
     a.setUrl("C:\\test_table.html");
     a.setQuery("<tr>.<td>2,4");
     for (a.moveFirst(); !a.isEOF(); a.moveNext()){
         document.write(a.getValueByIndex(1));
     }
</script>
</body>
</html>

-1: HTQL is not quite Python-friendly...

Answer 2

+4 A:

This should do it~

final_values=[td.string for td in bs.findAll('td', {'class':'datax'})[1::2]]

(after comment clarification) for your specific case it would be:

final_values=[td.b.a.string for td in bs.findAll('td', {'class':'datax'})[1::2]]

I think there is an error. I get [None, None, None ..... ]

Damiano 2010-05-10 14:22:15

>>> [td.string for td in soup.findAll('td', {'class':'datax'})[1::2]][u'b', u'd', u'f', u'h']unless bs isn't BeautifulSoup(source) this should work fine

hmmm i checked... td.string is None beacuse the value of td is -> <td class="datax"><b><a href="/q?s=AAU">AAU</a></b></td> (i have to get AAU)

[td.b.a.string for td in bs.findAll('td', {'class':'datax'})[1::2]]

dagoof 2010-05-10 14:46:10

ok, works! but the first has an <a href> the second no. So td.b.a.contents is wrong (works for the first but not for the second) how to do? thank you really much!

Damiano 2010-05-10 14:52:47

hmm I tried...but 1::2 doesn't works! i also get others colums values

Damiano 2010-05-10 14:58:06

@Damiano, you need to understand what 1::2 (http://docs.python.org/library/stdtypes.html#sequence-types-str-unicode-list-tuple-buffer-xrange) means and look into the BeautifulSoup doc. After that, you can adapt the code whatever the way you like.
