How to get value from table's td in BeautifulSoup?

Question

I have a page with some tables in its source:

<table width='100%' cellspacing='0' cellpadding='2' class='an'>
    <tr>
        <td width='35%' align='right'>XXX :</td>
        <td><b>20</b></td>
    </tr>
    <tr><
        td align='right'>XXX :</td>
        <td><b>XXX</b></td>
    </tr>
    <tr>
        <td align='right'>XX :</td>
        <td><b>XXX</b></td>
    </tr>
    <tr>
        <td align='right'>XXX :</td>
        <td><b>XXX</b></td>
    </tr>
    <tr>
        <td align='right'>XXX :</td>
        <td><b>XXX</b></td>
    </tr>
    <tr>
        <td align='right'>XXX :</td>
        <td><b>XXX</b></td>
    </tr>
    <tr>
        <td align='right'>XXX :</td>
        <td><b>XXX</b></td>
    </tr>
</table>

<table width='361' cellspacing='0' cellpadding='2' class='an'>
    <tr>
        <td width='35%' align='right'>XXX :</td>
        <td><b>XXX</b></td>
    </tr>
    <tr>
        <td align='right'>XXX :</td>
        <td><b>XXX</b></td>
    </tr>
    <tr>
        <td align='right'>XXX :</td>
        <td><b>XXX</b></td>
    </tr>
    <tr>
        <td align='right'>XXX :</td>
        <td><b>XXX</b></td>
    </tr>
    <tr>
        <td align='right'>XX :</td>
        <td><a href='XXX'><b>XXX</b></a></td>
    </tr>
    <tr>
        <td align='right'>PHONE :</td>
        <td><b>518878943</b></td>
    </tr>
</table>

I would like to get from this page a phone number, from the second table:

<td align='right'>PHONE :</td>
<td><b>518878943</b></td>

However, my code:

page_src="""<table width='100%' cellspacing='0' cellpadding='2' class='an'>
    <tr>
        <td width='35%' align='right'>XXX :</td>
        <td><b>20</b></td>
    </tr>
    <tr><
        td align='right'>XXX :</td>
        <td><b>XXX</b></td>
    </tr>
    <tr>
        <td align='right'>XX :</td>
        <td><b>XXX</b></td>
    </tr>
    <tr>
        <td align='right'>XXX :</td>
        <td><b>XXX</b></td>
    </tr>
    <tr>
        <td align='right'>XXX :</td>
        <td><b>XXX</b></td>
    </tr>
    <tr>
        <td align='right'>XXX :</td>
        <td><b>XXX</b></td>
    </tr>
    <tr>
        <td align='right'>XXX :</td>
        <td><b>XXX</b></td>
    </tr>
</table>

<table width='361' cellspacing='0' cellpadding='2' class='an'>
    <tr>
        <td width='35%' align='right'>XXX :</td>
        <td><b>XXX</b></td>
    </tr>
    <tr>
        <td align='right'>XXX :</td>
        <td><b>XXX</b></td>
    </tr>
    <tr>
        <td align='right'>XXX :</td>
        <td><b>XXX</b></td>
    </tr>
    <tr>
        <td align='right'>XXX :</td>
        <td><b>XXX</b></td>
    </tr>
    <tr>
        <td align='right'>XX :</td>
        <td><a href='XXX'><b>XXX</b></a></td>
    </tr>
    <tr>
        <td align='right'>PHONE :</td>
        <td><b>518878943</b></td>
    </tr>
</table>
"""

soup = BeautifulSoup(page_src, 'html.parser')
divs = soup.findAll("table", {"class": "an"})
for div in divs:
    row = ''
    rows = [row in div.findAll('tbody').findAll('tr')]

Gives me such an error message:

Traceback (most recent call last):
  File "test.py", line 198, in <module>
    rows = [row in div.findAll('tbody').findAll('tr')]
AttributeError: 'ResultSet' object has no attribute 'findAll'

How to solve this and get the phone number from the page? Thanks

EDIT:

Partly solved. Partly, because I think my solution is ugly, but works. Maybe someone will come up with prettier solution?

tds = []
soup = BeautifulSoup(page_src, 'html.parser')
divs = soup.findAll("table", {"class": "an"})
for div in divs:
    rows = div.findAll('tr')
    for row in rows :
        tds.append(row.findAll('td'))
phone = str(tds[12][1])
phone = phone.replace("<td><b>", "").replace("</b></td>", "").strip()
print phone

Answer 1

Find the td element containing PHONE : and then get the following sibling element. One line:

soup.find("td", text="PHONE :").find_next_sibling("td").text
