Biztalk Map: Map repeating structures into a single node

Question

Simple one for the experts. I have the following two samples. Can somebody please guide me on how to achieve my output? Just a caveat. The Errorlist may or may not have errors in which case just an empty tag should suffice.
Input
<Detail Att1="a">
<Value1>Test</Value1>
<Value2>Test2</Value2>
<ErrorList>
<Error>Error_0</Error>
<Error>Error_1</Error>
<Error>Error_2</Error>
</ErrorList>
</Detail>
Output1: Could be one or more xmls depending on the number of errors
<Detail Att1="a">
<Value1>Test</Value1>
<Value2>Test2</Value2>
<Error>Error_0</Error>
</Detail>
<Detail Att1="a">
<Value1>Test</Value1>
<Value2>Test2</Value2>
<Error>Error_1</Error>
</Detail>
<Detail Att1="a">
<Value1>Test</Value1>
<Value2>Test2</Value2>
<Error>Error_2</Error>
</Detail>
Output 2: Concatenation of errors using a suitable delimiter (I used pipe..pls suggest)
<Detail Att1="a">
<Value1>Test</Value1>
<Value2>Test2</Value2>
<Error>Error_0 | Error_1 | Error_2</Error>
</Detail>
Thanks

Hello ZIntegrator,
for your second output case, you can build map like below . since error can occur zero or more times, make sure you set the "Error" element  max occurs property to unbounded and Min occurs to 0 in the input schema.
so just drop String concatenation and cumulative concatenation functiods like above.
and for String concatenation, supply second parameter as the character pipe  "|".  that's it, it should work.
And coming to your first output case, as per your input you have 3 error cases. so do you want to create 3 different xml messages?
please note that a map can only output one message (of course we can create more than one using transform shape in orchestration, that is different case).
if you want seperate xml documents to be generated for each error, then normal mapping cannot work.
