Mapping - message split

Question

Hi all,
I need a little bit help with message splitting.
I have message structure like below. The Error Node exists in all rows, in first part it is initial (with no value), then come rows with different error messages.
<Message1>
  <Row>
    <node1>a</node1>
    <node2>a</node2>
    <Errror/>
  </Row>
  <Row>
    <node1>a</node1>
    <node2>a</node2>
    <Errror/>
  </Row>
  <Row>
    <node1>a</node1>
    <node2>a</node2>
    <Errror>text_a</Errror>
  </Row>
  <Row>
    <node1>a</node1>
    <node2>a</node2>
    <Errror>text_b</Errror>
  </Row>
</Message1>
I need to split it into 2 messages so, that in first message will be rows without error, and in the second with. 
<Message1>
  <Row>
    <node1>a</node1>
    <node2>a</node2>
  </Row>
  <Row>
    <node1>a</node1>
    <node2>a</node2>
  </Row>
</Message1>
<Message2>
  <Row>
    <node1>a</node1>
    <node2>a</node2>
    <Errror>text_a</Errror>
  </Row>
  <Row>
    <node1>a</node1>
    <node2>a</node2>
    <Errror>text_b</Errror>
  </Row>
</Message2>
Is this feasible with graphical mapping? How can I can make the assignment of the row once to first and
other time to second message? Or do I have to use XSLT/ABAP? (I am not very familiar with java...) Thanks for any suggestions.

Hello,
Prateek, Jude,
I think you did not get the point.When I map it just in the simple way it will look like this:
Input rows:
1 - no error
2 - no error
3 - error
4 - error
5 - error
Output
Message1 rows:
1,2,3,4,5
Message2 rows:
1,2,3,4,5
I will have 10 rows in output (I want to have just 5 and in this way M1-1,2; M2-3,4,5).
Udo,
I have tried already this approach. However it does not work as desired.
I have mapped:
Error node -> not -> exists -> if
Input_message_Row -> then
output -> Output_message1_Row
Error node -> exists -> if
Input_message_Row -> then
output -> Output_message2_Row
However the decision is made on the first row, and the first row is mapped also to second message, and that is all. The next rows are not considered at all:
Input:
<ns0:Messages xmlns:ns0=...>
   <ns0:Message1>
      <ns1:MT...>
         <Row>
            <test1>11</test1>
            <Errror/>
         </Row>
         <Row>
            <test1>111</test1>
            <Errror/>
         </Row>
         <Row>
            <test1>111bb</test1>
            <Errror/>
         </Row>
         <Row>
            <test1>11a</test1>
            <Errror>a</Errror>
         </Row>
         <Row>
            <test1>11axx</test1>
            <Errror>axx</Errror>
         </Row>
      </ns1:MT...>
   </ns0:Message1>
</ns0:Messages>
Output:
<ns0:Messages xmlns:ns0=...>
   <ns0:Message1>
      <ns1:MT...>
         <Row>
            <test1>11</test1>
         </Row>
      </ns1:MT...>
   </ns0:Message1>
   <ns0:Message2>
      <ns1:MT2...>
         <Row>
            <test1>11</test1>
            <Errror/>
         </Row>
      </ns1:MT2...>
   </ns0:Message2>
</ns0:Messages>
