Hi Swaathi,
can you provide a sample of the data as a reference?
One option might be to create a flatfile dictionary/schema and then use pub.flatfile:convertToValues to produce an IntegrationServer-Document which than can be parsed/queried using XPATH-Queries for service pub.xml:queryXMLNode.
Please have a look at the FlatFile-Developers Guide as well as the IntegrationServer Built-In-Services Guide.
Regards,
Holger
