XML to HL7 Transformer
The XML to HL7 transformer generates an HL7 v2.x message using the data provided. You must provide a v2.xml source message. If you are using custom XML, provide an XSLT that formats your XML into v2.xml.
The information in this section applies to version 2.0.0 of the XML to HL7 Transformer component. Version 2.0.0 of the component includes support for v2.6 HL7 messages.
The transformer then performs the following actions:
1. Optionally reads a custom XML message using an XSLT that transforms the message to v2.xml format.
2. Reads the v2.xml source message.
3. Converts the message to an HL7 v2.x message.
4. Displays the HL7 v2.x target message.
Note:  It is important that you familiarize yourself with the v2.xml specification. Go to www.HL7.org. and search for "XML encoding rules for HL7 v2 messages." To access this specification, you must be a member of HL7.org.
Using Linux
For versions 1.1.1 and 2.0.0, check if the MSH segment in your data file ends with a version number and a line feed (LF), as shown in the following example:
IE: MSH|^~\&||^123457^Labs|||200808141530||ORU^R01|123456789|P|2.6
If it does, change the line feed to a carriage return (CR) to prevent the transformer from improperly parsing the file.
