problem with children() and attr('title')

problem with children() and attr('title')

I want a value out of my title attribute in my table. But it won't work.

Here is my code:
  1. $(tr.artikelDump).children().children('.aantalDump').attr('title');
This I use to get my title attribute out of my class aantalDump. But it is empty.

Here is my table where I try to get the title value from:
  1. <table>
  2. <tr class='artikelDump'>
  3.       <input type='hidden' class='bestelid' value='1' />
  4.       <input type='hidden' class='artikelid' value='555' />
  5.        <input type='hidden' class='leverancierid' value='26' />
  6.       <input type='hidden' class='omschrijving' value='omschrijving' />
  7.        <input type='hidden' class='informatie' value='info' />
  8.       <td class='aant'><input type='text' title='4' class='aantalDump' id='aantalDump' name='aantalDump' /></td>
  9.       <td class='pr'><input type='text' title='4.02' class='prijsDump' /></td>
  10.  </tr>"
  11. </table>
