Removing messages in mapping

Question

Hi, I'm trying to remove blank messages using a multimapping.
The source and target messages are the same: MT_A -- > MT_A
Source:
<MT_A>
    <id>1</id>
</MT_A>
<MT_A>
    <id>2</id>
    <telephone>1</telephone>
</MT_A>
Target.
I want to remove message with id 1 as that message doesn't have the telephone tag.
<MT_A>
    <id>2</id>
    <telephone>1</telephone>
</MT_A>
I've tried validating the telephone tag and removing the context from telephone tag and validating it does exit, but all I get is the first message with id 1. Any ideas?
Thanks.

Hi,
    I have executed your mapping,  You need to change the context to root as you are checking based on the MT_A. Even it works without using <customer> in middle.
Source:
<MT_A>     <id>1</id>
</MT_A>
<MT_A>
    <id>2</id>
    <telephone>1</telephone>
</MT_A>
Target.
<MT_A>
    <id>2</id>
    <telephone>1</telephone>
</MT_A>
Mapping:
telephone->exists->removecontext->  IfWithoutElse(True) -> (Source)MT_A->(target) MT_A->
remaining elements id and telephone direct mapping, This resolves your issue.
