how select select parent <tr> elements containing ccc , ddd in it, , no others?

i.e. xml below:

<table> <tr> <td>aaa</td> <td>bbb</td> <td>select</td> </tr> <tr> <td>ddd</td> <td>ccc</td> <td>select</td> </tr> <tr> <td>ccc</td> <td>ddd</td> <td>select</td> </tr> <tr> <td>aaa</td> <td>ccc</td> <td>select</td> </tr> </table>

select row:

<tr> <td>ccc</td> <td>ddd</td> <td>select</td> </tr>

alternatively, how select 3rd td (with select written in it) on same row of td's ccc & ddd?

an xpath look contains several location steps. each step creates context either predicate (within [...]) or next step. last step contains result set selected. can apply 1 or more predicates in step, cut down set.

this look selects tr element contains td element string value of aaa , td element string value of bbb.

//tr[td='aaa' , td='bbb']

this look select set containing 2 td nodes (<td>select</td>) sec , 3rd <tr>s (the ones have td='ccc' , td='ddd':

//tr[td='ccc' , td='ddd']/td[3]

instead of using and can stack predicates. each predicate reduces result set creating context in next predicate operates. has same effect above expression:

//tr[td='ccc'][td='ddd']/td[3]
