The Code

// Create an instance of the EDI Rules Reader
EDIRulesReader reader = new EDIRulesReader("C:\\EDIRules.Rules");

// Load EDI Rules

// After parsing the following dictionary lists are available for custom programming and application development
// All the elements in the rules file
this.elements = reader.Elements;

// All the segments in the rules file
this.segments = reader.Segments;

// All the composite segments in the rules file
this.compositeSegments = reader.CompositesSegments;
