I'm generating some xml files that needs to conform to an xsd file that was given to me. What's the best way to verify they conform? The Java runtime library supports validation. Last time I checked this was the Apache Xerces parser under the covers.

You should probably use a javax. The schema factory constant is the string http: You should not use the DOMParser to validate a document unless your goal is to create a document object model anyway. This will start creating DOM objects as it parses the document - wasteful if you aren't going to use them.

Here's how to do it using Xerces2.

1) Convert XML to Java...

A tutorial for this, here req. Since this is a popular question, I would also like to point out that java can validate against a "referred to" xsd, for instance if the. The problem with this approach is that the xmlsns: Here's an example that validates an XML file against any XSD's it references even if it has to pull them from the network:. You can avoid pulling referenced XSD's from the network, even though the xml files reference url's, by specifying the xsd manually see some other answers here or by using an "XML catalog" style resolver.

Spring apparently also can intercept the URL requests to serve local files for validations. Or you can set your own via setResourceResolverex:. See also here for another tutorial. Using Java 7 you can follow the documentation provided in package description.

I found this very usefull. Alternatively if you use Stax for writing content or a library that uses or can use staxWoodstox can also directly support validation when using XMLStreamWriter.

Here's a blog entry showing how that is done:. You can then use these objects to build an XML document based on Validating xml file with xsd in java schema. It has built-in support for schema validation, and can convert Java objects to an XML document and vice-versa.

Be fore warned though, it is a heavy weight solution. As for a tool to do this for you, XMLFox Validating xml file with xsd in java to be a decent freeware solution, but not having used it personally I can't say for sure. I found it to be very confusing and weird. The help instructions didn't seem to match the interface.

ScanQR 2, 1 6 Jeff 1, 3 15 Hours upon the net trying to find this; why haven't I learned to search SO first yet? How do i tell which parser you are using as i cant see a reference to either. How do i use an ErrorHandler with the above? Is is a case of just creating the ErrorHandler and associating it with the validator? SetErrorHandler as in the example in this SO question stackoverflow. Shouldn't execptions just be used for Validating xml file with xsd in java situations and not for control flow?

Kishawy 2, 8 38 In this answer you are going further and getting Validating xml file with xsd in java Parser object, which is not needed, right? We build our project using ant, so we can use the schemavalidate task to check our config files: I found this site to be helpful, too. Michael Campbell 1, 1 13 Here's an example that validates an XML file against any XSD's it references even if it has to pull them from the network: Or you can set your own via setResourceResolverex: Doesn't work for me, method resolveResource isn't called unless its set on schemaFactory, any idea?

Dunno, works for me. Make sure you're setting it via setResourceResolver but beyond that, maybe open new question This Validating xml file with xsd in java basically the same as the accepted answer. This solution seems to me a bit inefficient though, as it unnecessarily builds the DOM for the xml to parse: The validator accepts a Sourceso you can: Working this way, a SAXException would be thrown at the first error in the xml-file and Validating xml file with xsd in java then the validation.

But I want to know all! If I use an ErrorHandler own class that implements ErrorHandler instead, it recognizes all errors, but the try-catch-block of validator. How do I recognize an error in the class that invokes the validate-method of my validator? Thanks for your help! There are "errors" e. One fatal error typically stops the parsing. But a validation error does not stop it: Thus, it is necessary to provide an ErrorHandler if you need to do validation. SAXCount -f -s -n my.

In debian squeeze it is located in the package "libxerces-c-samples". The definition of the dtd and xsd has to be in the xml! You can't config them separately. This allows for simple XML validation from vim:!

Here's a blog entry showing how that is done: StaxMan 80k 24 I was surprised that it's not in the standard implementation. Also, is it getting much use? I think it's the right way to go, but there seems very little interest in it.
