beautiful soap returns None
===

I want to download some html pages and extract informations, each HTML page has this `table tag`:

    <table class="sobi2Details" style='background-image: url(http://www.imd.ir/components/com_sobi2/images/backgrounds/grey.gif);border-style: solid; border-color: #808080' >
    	<tr>
    		<td><h1>Dr Jhon Doe</h1></td>
    	</tr>
    	<tr>
    		<td></td>
    	</tr>
    	<tr>
    		<td></td>
    	</tr>
    	<tr>
    		<td>
    		  <div id="sobi2outer">
    		     <br/>
    		     <span id="sobi2Details_field_name" ><span id="sobi2Listing_field_name_label">name:</span>Jhon</span><br/>
    		     <span id="sobi2Details_field_family" ><span id="sobi2Listing_field_family_label">family:</span> Doe</span><br/>
    		     <span id="sobi2Details_field_tel1" ><span id="sobi2Listing_field_tel1_label">tel:</span> 33727464</span><br/>
    		  </div>
    		</td>
    	</tr>
    </table>

I want to access name (`Jhone`) ,family (`Doe`) and tel(`33727464`),I've used [beausiful soup][1] to access these span tags by id:

    name=soup.find(id="sobi2Details_field_name").__str__()
    family=soup.find(id="sobi2Details_field_family").__str__()
    tel=soup.find(id="sobi2Details_field_tel1").__str__()
but I don't know how to extract data into these tags.I tryed to use `children` and `content` attributes,but when I use theme as a `tag` It returns `None`:

    name=soup.find(id="sobi2Details_field_name")
    for child in name.children:
        #process content inside

but I get this error:

    'NoneType' object has no attribute 'children'
while when I use __str__() on it,it is not `None`!!
any Idea?
