Folks,

 Good morning. I'm new to this list, so that might be a FAQ, but based on my review of it I don't think so, hence my posting. I need a transformation that is, in a sense, "mutating". By this I mean I need the transform to incorporate itself into the output stream, along with the input content, wrapped in a generic container. Consider for example the following xml:

initial XML stream
<resultSet>
 <anElement>value</anElement>
 <anotherElement> value </anotherElement>
</resultSet>

subsequent XML stream

<differentresultSet>
 <anElement>value</anElement>
 <anotherElement> value </anotherElement>
</differentresultSet>

realize that these two streams are not available concurrently, but serially. I also don't want to cache the file explicitly to address this need. I would like to transform the first in such a way that a new transformation is produced, one that could transform the second when passed through it into a merged product, say something like the following:

<containers>
<container>
 <resultSet>
 <anElement>value</anElement>
 <anotherElement> value </anotherElement>
</resultSet>
</container>
<container>
<differentresultSet>
 <anElement>value</anElement>
 <anotherElement> value </anotherElement>
</differentresultSet>
</container>
</containers>

This would be able to add as many containers as required, one for each time it was called. The endpoint at any point in time would be parseable into a set of containers.

Does this make sense? Can someone give me a reasonable starting point?

Thanks, Alan
