Parsing using lxml and requests with python

Recently I was trying to parse html table from web page using lxml and requests the python code runs like this

>>>from lxml to html
>>>import requests
>>>page=requests.get('http://ift.tt/1KbRANb evening-star-candlestick-pattern')
>>>tree=html.fromstring(page.text)'

Then I would like to parse the following repetitive data block using lxml xpath function to get lists

<TR>
    <TD style="font-size: 11px;"><!-- <a href="/company-technical-details/<%=sr.getExchange()%>/<%=sr.getSymbol()%>/<%=sr.getName()%>" ><%= sr.getSymbol() %></a>  -->
                    AMTEKINDIA           </TD>
    <TD style="font-size: 11px; max-width: 135px;">AMTEK INDIA LIMITED</TD>
    <TD>                nse         </TD>
    <TD style="min-width: 60px; max-width: 60px;">02-01-2015</TD>
    <TD>78</TD>
    <TD>78.3</TD>
    <TD>72.25</TD>
    <TD>73.9</TD>

But unable to do so getting error Eg:

>>> symbol=tree.xpath('//TD[@style="font-size: 11px;"][@!-- [@a href="/company-t
echnical-details/[@%=sr.getExchange()%]/[@%=sr.getSymbol()%]/[@%=sr.getName()%]"
 ][@%= sr.getSymbol() %][@/a]  --]/text()')

giving Xpath eval error and

>>> prices=tree.xpath('//TD/text()')

returning list with no values Please help with the xpath function
