XML XSD Validator Policy

Use the XML Validator policy to validate a request against an XML Schema Definition (XSD). You can upload an XML XSD file to define the schema.

Important: This page describes Classic APIM. For APIM 3.0, refer to API Management 3.0.
Validates a request against an XML Schema Definition (XSD). You can upload an XML XSD file in the policy dialog as a valid Swagger XML document. If an invalid path or parameter or object is not defined in the schema, the client receives a Schema Validation Failed error.
Note: Alternatively, you can use the specification that you upload to create an API.

Policy execution order

The XML XSD Validator policy executes after the request has been authenticated. You can use both the XML XSD Validator and XML DTD Validator Policy policies concurrently as long as the schemas do not conflict.

Note: All expression enabled fields in API Policies take expressions from Understanding Expressions in SnapLogic and the API Policy Manager Functions

Settings

Field/Field set Description
When this policy should be applied An expression that defines one or more conditions that must be true for the policy to execute.

Example: The expression request.method == "POST" causes the policy to execute only on POST requests.

Edit DTD Launches the editor which allows you to define an XSD. The editor loads an existing XML document if defined previously. The editor lets you save XML in SnapLogic's file system or import existing XML documents from it.
