Validating xml against xsd in java code how to make a profile for online dating
Java makes it easy to write such a tool and this post demonstrates how easy it is to develop a simple XML validation tool in Java.The Java tool developed in this post requires JDK 8.I have done this so that the tool can be adapted to work even in environments with older versions of Java.The complete code listing for the Java-based XML validation tool discussed in this post is included at the end of the post. Validator is obtained from the /** * Validate provided XML against the provided XSD schema files.
Namespaces have been introduced to XML after the first specification of XML had received the official W3C Recommendation status.
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.
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.
