html - CSS Selector only selects the first row -

i parsing html page , have long css selector (i can't figure out shorter one, because page stupid). should select tr in table, selects 2nd row... missing?

the selector:

body > table:nth-child(1) > tbody:nth-child(1) > tr:nth-child(2) > td:nth-child(1) > table:nth-child(1) > tbody:nth-child(1) > tr:nth-child(3) > td:nth-child(1) > table:nth-child(1) > tbody:nth-child(1) > tr:nth-child(8) > td:nth-child(1) > table:nth-child(4) > tbody:nth-child(1) > tr:nth-child(2) > td:nth-child(1) > table:nth-child(1) > tbody:nth-child(1) tr:not(:first-child) 

the page has multiple tables inside each other, first 90% not matter, after selecting table want work with, follow "[space]tr:not(...)", should select descending rows, shouldn't it?

example html page (cannot link it, need login access it): http://pastebin.com/gprxtvzz

after selector selects table want (in selector ...> tbody:nth-child(1) tr:not(:first-child) ), age looks this:

<tbody>    <tr valign="bottom">       <td class="blackmedium" width="80"><b>part number</b></td>       <td class="blackmedium" width="100"><b>manufacturer</b></td>       <td class="blackmedium" width="40"><b>abbr.</b></td>       <td class="blackmedium" width="50"><b>wix part number</b></td>       <td class="blackmedium" width="50"><b>lead time</b></td>    </tr>    <tr>       <td class="blackmedium" width="80">a0002701098</td>       <td class="blackmedium" width="100">mercedes-benz</td>       <td class="blackmedium" width="40">mbz</td>       <td class="blackmedium" width="50"> <a href="http://www.wixindustrialfilters.com/cross.aspx?part=w03at780" target="_blank">w03at780</a>       </td>       <td class="blackmedium" width="50">          stock       </td>    </tr>    <tr bgcolor="#e0e0e0">       <td class="blackmedium" width="80">a0002701598 discontinued</td>       <td class="blackmedium" width="100">mercedes-benz</td>       <td class="blackmedium" width="40">mbz</td>       <td class="blackmedium" width="50"> <a href="javascript:var w=window.open('partdetail.asp?part=58892','partdetail','left=200,top=200,width=530,height=500,toolbar=no,location=no,directories=no,status=no,menubar=no,resizable=yes,scrollbars=yes');w.focus();">58892</a>       </td>       <td class="blackmedium" width="50">       </td>    </tr>    <tr>       <td class="blackmedium" width="80">a0002772395</td>       <td class="blackmedium" width="100">mercedes-benz</td>       <td class="blackmedium" width="40">mbz</td>       <td class="blackmedium" width="50"> <a href="javascript:var w=window.open('partdetail.asp?part=51249','partdetail','left=200,top=200,width=530,height=500,toolbar=no,location=no,directories=no,status=no,menubar=no,resizable=yes,scrollbars=yes');w.focus();">51249</a>       </td>       <td class="blackmedium" width="50">       </td>    </tr>    <tr bgcolor="#e0e0e0">       <td class="blackmedium" width="80">a0002772895</td>       <td class="blackmedium" width="100">mercedes-benz</td>       <td class="blackmedium" width="40">mbz</td>       <td class="blackmedium" width="50"> <a href="javascript:var w=window.open('partdetail.asp?part=57701','partdetail','left=200,top=200,width=530,height=500,toolbar=no,location=no,directories=no,status=no,menubar=no,resizable=yes,scrollbars=yes');w.focus();">57701</a>       </td>       <td class="blackmedium" width="50">       </td>    </tr> </tbody>

not answering question, in case markup not parsing-friendly , need find nested in terrible markup table element, prefer find presence of specific header in it. in case, may locate table having part number header. example xpath:

//table[tr[1]/td/b = "part number"] 

then, on table can use "not first child" css selector:

tr:not(:first-child) 

or, may use adjacent selector (find tr elements after tr element, logically exclude first row):

tr + tr 

hope simplify things.
