Fetching sequential children

Hey,

Under the main node of my application I have the following sequential children:  mytest1, mytest2, mytest3, sometest1,sometest2,sometest3.
Now, I want to get all children of my main node that starts with mytest, something like getChildren("/main/mytest*", false), is there a command for that? Or must I bring all children and filter out the unwanted ones?

You may create the parent node first: /main/mytest
Then create sequential children under it:
create_sequential('/main/mytest/mytest')
...
/main/mytest/mytest0000000001
/main/mytest/mytest0000000002
/main/mytest/mytest0000000003
..
So you could get all sequential children by get_children('/main/mytest')

Hi ohad,
  there isnt a way to get a selected set of children from the servers. So
you will have to get all of them and filter out the unwanted ones. Also,
what Steve suggested in the other email might be useful for you.

Thanks
