[Servingxml-help] Writing to a buffer

[Ravikumar T. <ra...@gm...>]

Hi

I am converting a large flat file to xml using servingXml. I am trying to
write the xml to a buffer instead of a physical file. After certain number
of lines/records are transformed to xml, I am planning to invoke a listener
or trigger which would consume/process the xml generated so far and return
control so that the next set of records are converted. I am considering the
following approach:

Write a record filter and maintain a count of records. After the desired
number of records are written, I notify a listener which can process the xml
produced so far. I see an issue with this. The writeRecord method doesnot
tell me if I am at the end of the file. So I wouldnot know when to fire the
listener for the last set of records.  Please let me know if this approach
can be followed.

Regarding writing to a buffer, I would like to use a java.io.StringWriter so
that I can read from it. But OutputStreamSinkAdaptor doesnot take a
java.io.Writer as a parameter to the constructor. It would only take an
OutputStream. Is there any other way I can write to a buffer which can also
be read and cleared while the xml transformation is in progress.
