hi Arun
Please find the screenshot attached
11.gip shows the xml_pipeline transform... where all nodes are nested and column is "unavailabilitytype" which is int in source xml file... xml_pipline transform further connects with Query transform where all nodes got unnested... where as well "unavailabilitytype" datatype showing as int
12.gif show the another query transform where i used cast function..
dataflow is like
source_xml_file->xml_pipeline->query_transform_1->query_transform_2->template_target_table
