Java validating xml against schema

In this post I'll describe how to leverage those APIs during unmarshal and marshal operations.package validation; import The data is quite similar to what is available from a SAXParse Exception. EVENT SEVERITY: 1 MESSAGE: cvc-max Length-valid: Value 'Jane Doe' with length = '8' is not facet-valid with respect to max Length '5' for type 'string With Max Size5'. SAXParse Exception: cvc-max Length-valid: Value 'Jane Doe' with length = '8' is not facet-valid with respect to max Length '5' for type 'string With Max Size5'. EVENT SEVERITY: 1 MESSAGE: cvc-max Length-valid: Value 'Jane Doe' with length = '8' is not facet-valid with respect to max Length '5' for type 'string With Max Size5'. Validating Marshal Record$Marshal SAXParse Exception: cvc-max Length-valid: Value 'Jane Doe' with length = '8' is not facet-valid with respect to max Length '5' for type 'string With Max Size5'.

Namespaces have been introduced to XML after the first specification of XML had received the official W3C Recommendation status.

This is the reason why (most of the) XML parser implementations do not support XML Namespaces by default, to handle the validation of XML documents with namespaces correctly it is therefore necessary to configure the underlying parsers to provide support for XML Namespaces.

In the earlier tutorials we saw how to build a JDOM2 document using SAXBuilder. Now lets look at an example that shows how to specify an XSD externally.

We also saw how to validate the document using DTD while using the SAXBuilder. The example below specifies two methods to specify an XSD externally.

In this tutorial we look at how to use the SAXBuilder that validates against an XSD.

The example below shows how to use an internally defined XSD. We have tried the DOM interface in previous sections. Here is a tutorial example program called Xsd Schema Sax that validates an XML file against an XSD file using the SAX interface: /* * Xsd Schema Sax - Copyright (c) 2013, Herong Yang.com, All Rights Reserved. I described how to validate an object model (mapped with JAXB annotations) against an XML schema using the validation APIs. The event is represented as an instance of Validation Event, and provides many details about the issue. The 3rd event is related to the extra "phone-number" element.
