The virtual XML used by GNQuery includes also tasks and taskLogs informations. They are indentified by an extra ‘nav:taks’and ‘nav:taskLogs’ XML element containing ‘nav:task’ and ‘nav:taskLog’ elements.

Example:

<nav:tasks handle="1">

  <nav:task 

    id="..." userId="..." time="..." priority="..." type="..." objectId="..." 

    profile="..." numRetries="..." cmd="...">

    <user idref="...">

      <nav:refObject idref="...">

        <user id="..." name="..." . . .  />

      </nav:refObject>

    </user>

    <object idref="...">

      <nav:refObject idref="...">

        <pubDest id="..." name="..." path="..." ...  />

      </nav:refObject>

    </object>

  </nav:task>

  ...

</nav:tasks> 

   

<nav:taskLogs handle="1">

  <nav:taskLog 

    id="..." time="..." result="..." type="..." priority="..." 

    execProc="..." profile="..." objectid="..." cmd="..." userId="...">

    <user idref="...">

    </user>

    </object>

  </nav:taskLog>

  ...
