Validating xml schema java speed dating redondo beach
The Error Handler used for the examples is a very simple one which reports the error to and continues until the XML document has been fully parsed or until a fatal-error has been reported.
Namespaces have been introduced to XML after the first specification of XML had received the official W3C Recommendation status.
The input document contains an extra attribute which has not been defined in the XML Schema, this shows that the XML Schema has been used for the validation.
When using this XML Schema to validate the input XML document, the following error gets reported: ) as defined below has been used in the code examples to validate the input document.
(To learn more about XML Schema, you can review the online tutorial, XML Schema Part 0: Primer.
I have done this so that the tool can be adapted to work even in environments with older versions of Java.Configure Java APIs (SAX, DOM, dom4j, XOM) using JAXP 1.3 to validate XML Documents with DTD and Schema(s).Many Java XML APIs provide mechanisms to validate XML documents, the JAXP API can be used for most of these XML APIs but subtle configuration differences exists.W3C_XML_SCHEMA_NS_URI); // load a WXS schema, represented by a Schema instance Source schema File = new Stream Source(new File("my Schema.xsd")); Schema schema = Schema(schema File); // create a Validator instance, which can be used to validate an instance document Validator validator = Validator(); // validate the DOM tree try catch (SAXException e) on a parser factory.The former technique will cause parsers to use the new validation API; the latter will cause parsers to use their own internal validation facilities.
