    Accessing Validated EDI Data

    Because EDIValidator creates an EDILightWeightDocument after validation, consuming EDI data is done the same way as getting data from the EDILightWeightDocuments.

    Example

    validator.validate();
     
    let doc = validator.EDILightWeightDocument;
     
    //Write out a visual representation of the loaded EDI document
    writeDocumentTree(doc.Loops.getItem(0), 0);
     
    function writeDocumentTree(loop, indent) {
        if (loop != null) {
     
            for (let i = 0; i < indent; i++) {
                process.stdout.write(”   “);
            }
     
            console.log(loop.Name);
     
            indent++;
            writeSegment(loop.Segments, indent);
     
            if (loop.Loops != null) {
                for (let i = 0; i < loop.Loops.Count; i++) {
                    writeDocumentTree(loop.Loops.getItem(i), indent);
                }
     
                indent++;
            }
        }
    }
     
    function writeSegment(segments, indent) {
        for (let i = 0; i < segments.Count; i++) {
            let seg = segments.getItem(i);
            for (let i = 0; i < indent; i++) {
                process.stdout.write(”      “);
            }
     
            console.log(seg.Name);
     
            writeElement(seg.Elements, indent);
        }
    }
     
    function writeElement(elements, indent) {
        for (let i = 0; i < elements.Count; i++) {
            let elem = elements.getItem(i);
     
            for (let i = 0; i < indent; i++) {
                process.stdout.write(”       “);
            }
            if (elem.Composite) {
                console.log(“Composite”);
    //Check for composite elements
                if (elem.Elements != null && elem.Elements.Count > 0) {
                    writeElement(elem.Elements, ++indent);
                    indent–;
                }
     
            } else {
                console.log(“[” + elem.DataValue + “]”);
            }
        }
    }
     
    Using the above functions a hierarchical visual tree could easily be created for display.  For example,
