Where can I find the Java implementation for Schematron ISO authentication?

Question

The ISO Schematron standard has been around for two years, but I still can’t find a Java implementation using the Schematron XSLT ISO files (unlike files from an older version of Schematron, for example here: http://uploading.com/files/c9c9cb87/SchematronXpath .jar / ).

Does anyone know about an ISO ready-to-release schema that can be easily called from a Java method?

Answer 1

In addition, you can use ph-schematron , which provides both support for conversion to XSLT, and its own regular Java check, which runs faster than the XSLT version in almost all cases. See https://github.com/phax/ph-schematron/ for more details, as well as a brief introduction. Sample code to verify that an XML file matches a Schematron file:

 public static boolean validateXMLViaPureSchematron (File aSchematronFile, File aXMLFile) throws Exception { final ISchematronResource aResPure = SchematronResourcePure.fromFile (aSchematronFile); if (!aResPure.isValidSchematron ()) throw new IllegalArgumentException ("Invalid Schematron!"); return aResPure.getSchematronValidity(new StreamSource(aXMLFile)).isValid (); }

Probatron4j can verify compliance with ISO Schematron. The website provides a single standalone JAR that is designed to be run from the command line, but it is easy to call Probatron from the Java method if you have its source code . Here is a simplified version of how I did this:

 public boolean validateSchematron(InputStream xmlDoc, File schematronSchema) { // Session = org.probatron.Session; think of it as the Main class Session theSession = new Session(); theSession.setSchemaSysId(schematronSchema.getName()); theSession.setFsContextDir(schematronSchema.getAbsolutePath()); // ValidationReport = org.probatron.ValidationReport; the output class ValidationReport validationReport = null; try { validationReport = theSession.doValidation(xmlDoc); } catch(Exception e) { /* ignoring to keep this answer short */ } if (validationReport == null || !validationReport.documentPassedValidation()) { return false; } return true; } 

You need to make a few minor changes so that Probatron does not know that it does not start from the JAR file, but it does not take much time.

You can check out SchematronAssert (expansion: my code). It is intended primarily for unit testing, but you can also use it for regular code. It is implemented using XSLT.

Device Test Example:

 ValidationOutput result = in(booksDocument) .forEvery("book") .check("author") .validate(); assertThat(result).hasNoErrors(); 

Standalone verification example:

 StreamSource schemaSource = new StreamSource(... your schematron schema ...); StreamSource xmlSource = new StreamSource(... your xml document ... ); StreamResult output = ... here your SVRL will be saved ... // validation validator.validate(xmlSource, schemaSource, output); 

Working with the SVRL Object View:

 ValidationOutput output = validator.validate(xmlSource, schemaSource); // look at the output output.getFailures() ... output.getReports() ...

The jing library works for me.
