Validating xml against xsd in java
Create Test Xml Schema Validation class as shown below: Use XMLStream Reader2.validate Against() method to validate the XML document against the XML schema (see line 29 below).
Note that it is in accordance with described above as it defines the ‘title’ element (see line 4 below) instead of ‘salary’ element.
To highlight that the DTD has been used for the validation, the title attribute in the input document has a value which is not allowed according to this DTD.
When using this DTD to validate the input XML document, the following error gets reported: Before a document can be called XML and not csv, simple text or any other format, it needs to support the basic rules as defined by the XML Recommendation, when it adheres to these rules it is said to be Wellformed XML.
A Document Type Definition (DTD) defines which elements and attributes you can use inside an XML document.
Typically this DTD document is specified inside the XML document.
In this example we explain haw you can validatie an XML document against a DTD using JDom.package com.jdom; import org.jdom2.
This article demonstrates how to validate an XML document against an XML Schema by using Woodstox. It defines the employee element that contains id, name and salary sub-elements. From the main method, first successfully validate the valid file (see line 45 below).
) as defined below has been used in the code examples to validate the input document.This article shows five ways of how to configure different Java APIs (including DOM, SAX, dom4j and XOM) using JAXP 1.3 for checking and validating XML with DTD and Schema(s).To report errors, it is necessary to provide an Error Handler to the underlying implementation.This post shown how JAXB2 Schema validation can be used in your project, validating the generated XML against specific XML Schema Definition [XSD].An XML Schema Definition describes the structure of an XML document and governs the rules and constraints being applied on XML content.
