XmlValidator

XmlValidator is a utility for simple XML validation. In the left panel you can write, paste or read XML from an existing file. The existing schema can be checked, after pressing the "Validate" button at the bottom, "XML is well formed" or an error message will appear. If you check "Discover schema from XML", the referenced schema will be used if it exists. In the right pane, you can put the schema definition (XSD) and choose validation. The resulting message will be "XML is valid" or a list of errors will be displayed. XmlValidator needs the Microsoft .NET Framework v4.0 to run. The installer will attempt to download and install it if necessary.
