var value = source.getAllNodes('OBX-3.1');
var found = false;
for (var i = 0; i < value.length; i++) {
if (StringUtils.equalsIgnoreCase(value[i], '123')||
StringUtils.equalsIgnoreCase(value[i], '456') ||
StringUtils.equalsIgnoreCase(value[i], '789') ||
StringUtils.equalsIgnoreCase(value[i], '111') ||
StringUtils.equalsIgnoreCase(value[i], '222')) {
found = true;
}
if (found) {
