How do I validate payloads against a schema using XML with Swift?

Validating XML Payloads Against a Schema in Swift

When working with XML data in Swift, it's often necessary to validate the XML against a defined schema (XSD) to ensure that the XML structure and data types are as expected. This can help prevent errors during data processing. Below is an example of how to perform this validation.

// Here is a simple example of how to validate XML against an XSD schema in Swift import Foundation func validateXML(xmlString: String, xsdString: String) -> Bool { guard let xmlData = xmlString.data(using: .utf8), let xsdData = xsdString.data(using: .utf8) else { return false } do { let xmlDoc = try XMLDocument(data: xmlData) let schema = try XMLSchema(xmlData: xsdData) return schema.validate(xmlDocument: xmlDoc) } catch { print("Error during validation: \(error.localizedDescription)") return false } } let xml = "ToveJaniReminderDon't forget me this weekend!" let xsd = """ """ let isValid = validateXML(xmlString: xml, xsdString: xsd) print("XML is valid: \(isValid)")
