python 2.7 - How to concatenate XPath in scrapy -

-

i struggling quite time on issue. table need extract annual div instead of annual div yield. 

<table class="horizontaltable col1of3 lastcol">   <tbody>     <tr class="first">       <th>annual div <span class="sub">(ttm)</span></th>       <td>5.49 <span class="currencycode">gbx</span></td>     </tr>     <tr>       <th>annual div yield <span class="sub">(ttm)</span></th>       <td>6.04%</td>     </tr>     <tr>       <th>div ex-date</th>       <td><span class="nowrap">sep 25 2013</span></td>     </tr>     <tr class="last">       <th>div pay-date</th>       <td><span class="nowrap">nov 22 2013</span></td>     </tr>   </tbody> </table>

i wrote xpath query bringing both annual div , annual div yield 

annual_div = sel.xpath('//table[contains(@class, "horizontaltable col1of3")]/tbody/tr[th[contains(.,"annual div")]]').extract()

result:

<tr class="first"><th>annual div <span class="sub">(ttm)</span></th><td>5.49 <span class="currencycode">gbx</span></td></tr>', u'<tr><th>annual div yield <span class="sub">(ttm)</span></th><td>5.83%</td></tr>

when write match on excact text result not yield result: 

annual_div = sel.xpath('//table[contains(@class, "horizontaltable col1of3")]/tbody/tr[th[text()="annual div"]]').extract()

it seems span (ttm) not sure how concatenate both annual div (ttm) come exact match.

please me.

regards

to compare exact match missing whitespace @ end. should work:

//table[contains(@class, "horizontaltable col1of3")]/tbody/tr[th/text() = "annual div "]]

however, if want remove leading , trailing spaces can use nornmalize-space() so:

//table[contains(@class, "horizontaltable col1of3")]/tbody/tr[normalize-space(th/text()) = 'annual div']
