</organization>
`;
parseString(xmlData, (err, result) => {
if (err) {
console.error('Error parsing XML:', err);
return;
}
const orgName = result.organization.name[0];
const founder = result.organization.founder[0];
const location = result.organization.location[0];
console.log('Organization Name:', orgName);
