Kannada online chat - Validating database schema

The actual validation is performed by the Xerces2 library.

When parsing an XML document a reference to a grammar (either DTDs or XSDs) is found, then the parser attempts resolve the grammar reference by following either the XSD xsi:schema Location, xsi:no Namespace Schema Location hints, the DTD DOCTYPE SYSTEM information, or by outsourcing the retrieval of the grammars to an Xml Catalog resolver.

The jaxp() and jaxp-report() functions accept the following parameters: The JAXV validation functions are based on the validation API which has been introduced in Java 5 to provide a schema-language-independent interface to validation services.

Although officially the specification allows use of additional schema languages, only XML schemas can be really used so far.

The jaxv() and jaxv-report() functions accept the following parameters: The Jing validation functions are based on James Clark's Jing library.

e Xist-db supports implicit and explicit validation of XML documents.

Implicit validation can be executed automatically when documents are being inserted into the database, explicit validation can be performed through the use of provided XQuery extension functions.

All grammars (XML schema, DTD) that are used for implicit validation must be registered with e Xist using OASIS catalog files.These catalog files can be stored on disk and/or in the database itself.In e Xist the actual resolving is performed by the apache xml-commons resolver library.It is possible to configure any number of catalog entries in the entity-resolver section of .The relative "uri="s are resolved relative to the location of the catalog document.The JAXP validation functions are based on the validation capabilities of the parsers API.
