Validating xml file against xsd in java

I found it to be very confusing and weird. The help instructions didn't seem to match the interface. The drawback: the validation capability is not in the free version, so I had to use the 30 day trial. Stack Overflow for Teams — Collaborate and share knowledge with a private group.

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 execptional situations and not for control flow? Won't this code only catch fatal errors? If you want to be able to catch non-fatals such as non-structural ones I think you will need to use an ErrorHandler. Show 3 more comments.

In this answer you are going further and getting a Parser object, which is not needed, right? 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 Resurrecting an old post, I think it should read xsi:schemaLocation instead of xsi:SchemaLocation - case matters. See w3. Stephan Paulo Fidalgo Paulo Fidalgo We can do this by marshaling an object to a StringWriter.

Alternatively, we could craft XML data as a string. For this post, convert a JAXB object to a string object. Consider the following method. We can use the String object to compare against an XSD. Consider the following codes. Notice we use a string that represents an XML. See lines 10 — Validator instance by calling newValidator method on schema object. Finally, call a validate method on a validator object by inputting XML file.

We should also create ErrorHandler by an overriding warning , error and fatal methods and pass this to setErrorHandler on validator, which captures xsd messages.

When you run this example, it returns all XSD error, fatal and warning messages in a list. This code would be similar to the above and just the syntax would be different.
