The Java tool developed in this post requires JDK 8.
However, the simple Java application can be modified fairly easily to work with JDK 7 or even with a version of Java as old as JDK 5.
Now that the program is ready to validate with an XML Schema definition, it is necessary only to ensure that the XML document is associated with (at least) one.
There are two ways to do that: , which stands for "XML Schema instance." The second line specifies the schema to use for elements in the document that do not have a namespace prefix-that is, for the elements you typically define in any simple, uncomplicated XML document.
SAXException; public class XMLValidation Employee validates against Employee.xsd? true Exception: cvc-elt.1: Cannot find the declaration of element ' Employee'.
Shouldn't execptions just be used for execptional situations and not for control flow? Also take a look at stackoverflow.com/questions/15732/…In case someone gets error "No Schema Factory tha implements [...]", it's maybe because you did the same error as me, which was using the constant XMLConstants.
I wouldn't consider it execptional, if execute a 'test'.
This might depends on the library you use but googling around with "how to validate xml file in java" gave me these results where you might find your answer: first interesting result second interesting result Validator v = Language(Languages.
The validator will report fatal errors, non-fatal errors and warnings.
If the XSD is publicly available using HTTP and referenced through a "schema Location" or "no Namespace Schema Location", then the validator will pick it up and it doesn't need to be specified/uploaded.
Be careful because the validator is not thread safe.
It is the responsibility of the application to make the code thread safe.
I have found it useful to have my own easy-to-use XML validation tool because of limitations or issues of the previously mentioned approaches.
