Unstructured data (or unstructured information) is information that either does not have a pre-defined data model or is not organized in a pre-defined manner. Unstructured information is typically text-heavy but may contain data such as dates, numbers, and facts as well.
I'm facing an issue while converting an ORU_R01 HL7 message to XML, specifically with the <pidgrpgrp> kind elements. When I use the getvalueat() method before conversion, the XML includes the <pidgrpgrp> and other <grp> elements, but when I don't use the getvalueat() method, the XML is generated without these <grp>elements.
