Validating xml against xsd in java code indian speed dating events uk

When you pass a URI identifying a particular schema language to that know how to process your schema language.

Then, install your JAR in one of these four locations.

Recently in my project, I had a requirement to validate XML file against XSD schema file and list all validation errors.

validating xml against xsd in java code-14

The validator checks for well formedness first, meaning that your XML file must be parsable using a DOM/SAX parser, and only then does it validate your XML against the XML Schema.

The validator will report fatal errors, non-fatal errors and warnings.

LOCATOR LINE NUMBER: 3 COLUMN NUMBER: 25 OFFSET: -1 OBJECT: null NODE: null URL: null EVENT SEVERITY: 1 MESSAGE: cvc-complex-type.2.4.d: Invalid content was found starting with element 'customer'.

Xml Root Element; @Xml Root Element public class Customer package example; import LOCATOR LINE NUMBER: 3 COLUMN NUMBER: 25 OFFSET: -1 OBJECT: null NODE: null URL: null EVENT SEVERITY: 1 MESSAGE: cvc-type.3.1.3: The value 'Jane Doe' of element 'name' is not valid. SAXParse Exception: cvc-type.3.1.3: The value 'Jane Doe' of element 'name' is not valid. SAXParse Exception: cvc-complex-type.2.4.d: Invalid content was found starting with element 'customer'.

Now to list all errors in one go, we need to populate list of errors by overriding error handling behaviour of the validate().

We need to add a custom Error Handler which populates a list of validation errors. Validator validator = Validator() List exceptions = [] //Empty list to store errors //Create a custom error handler that populates the list when errors occur.

To validate an XML file against an XSD file, we normally do something like this: SAXParse Exception is thrown by validate() when first validation error is encountered in the XML file.

We can use ‘line Number’ and ‘column Number’ fields of SAXParse Exception object to know where exactly the error is.

This package is also available in Java 1.3 and later when you install JAXP 1.3 separately.
