c# - Get a node from a node from Xml -

i have simple xml file. looks this:

<?xml version="1.0" encoding="utf-8" ?>  <activities>   <task>     <name> task1 </name>     <time> 00:00 </time>      <subtask>       <name> task1 - subtask1 </name>       <time> 00:00 </time>     </subtask>      <subtask>       <name> task1 - subtask2 </name>       <time> 00:00 </time>     </subtask>    </task>    <task>     <name> task2 </name>     <time> 00:00 </time>      <subtask>       <name> task2 - subtask1 </name>       <time> 00:00 </time>     </subtask>    </task>  </activities> 

my question how each subtask nodes each tasks? example first of want task 1 , relevant subtasks (subtask1, subtask2) , data.

how in c# in appropriate way? i'm new xml. :)

use xpath syntax select need.

use xmldocument class in .net along xpath expression.
