--------------------------------------
@Rajesh,
Lets stick to XalanJ version 2.7.2 for this discussion (since that is the
latest release).
You haven't posted your XML input document for the XSLT transform. From your
attached java code, it seems that would be 20200219_131219.xml. Please provide
that XML document, for someone to debug this issue.
