Using variable for file naming only and not in xml payload?

I’m formatting and writing an xml file, and would like to name the file based on a field value from the original file, but cannot be part of the xml. Is it possible to somehow bring a variable ($VAR...

    @acesario You can segregate xml format and file writer in different pipeline, then call this child pipeline using Pipeline execute and pass input param(the filename you want ) from your parent pipeline. Even if you use xsd inside xml format, you can found the xsd structure from the mapper(Map to xml) of your parent pipeline.

    @Supratim Thanks for the quick response! I actually had tried using a separate pipeline, and was able to pass the parm as you suggest, however my xml output would be one row, rather than the aggregated rows. So, a. I was doing this before the map to xml. I could try it after that.
    Or better yet, b. Is there a way to have sub pipeline produce the aggregated rows, just like the parent does?

    What I mean is, Parent produces xml:
    <#root>
    <#row1>
    <#row2>
    <#row3>
    <#/root
    …
    Child (sub) currently produces
    file1…
    <#root>
    <#row>
    <#/root>
    file 2…
    <#root>
    <#row>
    <#/root>
    file 3…
    <#root>
    <#row>
    <#/root>

      Actually you pass each row from pipeline execution snap, Move mapper to child pipeline , it should work.
      Unless the upstream snap of mapper produce multiple output of row.
