findInXml.js

        //gets events from EventDataList.xml
        //for viewing in time legend
        async function getEventDescription(eventName) {
            //search for matching event name
            var eventXmlList = window.$EventDataListXml.find('Event'); //get all event elements
            var results = eventXmlList.filter(
                function () {
                    var eventNameXml = $(this).children('Name').eq(0);
                    return eventNameXml.text() === eventName;
                });

            //get description text out of the event xml record
            var eventDescription = results.eq(0).children('Description').eq(0).text();

            //remove tabs and new line to make easy detection of empty string
            let cleaned = eventDescription.replace(/ {4}|[\t\n\r]/gm, '');
            return cleaned;
        }
