Crate hl7_2_from_er7_into_xml 

Convert HL7 v2.5 messages from ER7 (pipe-delimited) encoding to the HL7 v2.xml XML representation (urn:hl7-org:v2xml).

The ER7 encoding itself — parsing, delimiters, escape sequences — comes from the er7 crate. This crate adds the layer above it: the HL7 v2.5 data-type tables that name XML elements, the message-structure grammars that group segments, and the XML renderer. See spec/index.md for the exact conversion rules (source of truth).

let er7 = "MSH|^~\\&|hphis||EPIC||20131011093851||ORM^O01|14AAACVDD|P|2.5\r\
           PID|1||241900||MEDIANO^FOUAZ\r\
           ORC|NW|ORD1";
let xml = hl7_2_from_er7_into_xml::convert(er7).unwrap();
assert!(xml.contains("<ORM_O01 xmlns=\"urn:hl7-org:v2xml\">"));
assert!(xml.contains("<XPN.1>"));

Modules

structure

Arranging a message’s segments into the groups its structure defines.

convert

Convert one ER7 message to a v2.xml document with default options.

convert_with_dictionary
