[Tutor] weather scraping with Beautiful Soup

[Che M]

OK, got the very basic case to work when using Beautiful Soup 3.0.7a and scraping the Weather Underground Lite page.  That gives me the current temperature, etc.  Good.

But now I would like the average temperature from, say, yesterday.  I am again having trouble finding elements in the soup.  This is the code:

----------------------
import urllib2
from BeautifulSoup import BeautifulSoup

url = "http://www.wunderground.com/weatherstation/WXDailyHistory.asp?ID=KPAJAMES1&month=7&day=16&year=2009"
page = urllib2.urlopen(url)
soup = BeautifulSoup(page)

table = soup.find("td",id="dataTable tm10")
print table

------------------------

When I look at the page source for that page, there is this section, which contains the "dataTable tm10" table I want to zoom in on:
------------
<table cellspacing="0" cellpadding="0" class="dataTable tm10">
		<thead>
		<tr>
		<td style="width: 25%;">&nbsp;</td>
		<td>Current:</td>
		<td>High:</td>
		<td>Low:</td>
		<td>Average:</td>
		</tr>
		</thead>
		<tbody>
		<tr>
		<td>Temperature:</td>
		<td>
  <span class="nobr"><span class="b">73.6</span>&nbsp;&#176;F</span>
</td>
		<td>
  <span class="nobr"><span class="b">83.3</span>&nbsp;&#176;F</span>
</td>
		<td>
  <span class="nobr"><span class="b">64.2</span>&nbsp;&#176;F</span>
</td>
		<td>
  <span class="nobr"><span class="b">74.1</span>&nbsp;&#176;F</span>
</td>
--------------

And yet when I run the above code, what it prints is:

>> None

In other words, it is not finding that table.  Why?  

Help appreciated again.
