    hi your blog is realy good. Could you please write a post on how to convert XML data to HL7 in Mirth. Scenario is that there is a column in DB which stores guarantor info in xml format and while sending an Outbound message, i am able to convert all other fields as they are simple text. i am stuck in converting the guarantor xml field to GT1 segment in HL7. Any suggestion would be highly appreciated.

      If “Guarantor” is the only field in XML format, I will advise to use a string match method on some condition and extract the info using the substring method.
      Otherwise get me a few more details on rajesh4it@gmail.com
