Validating XML

Hi everyone,

I would like to validate a XML file by using SAX API. I don't know which API is the right one. Also, how and where do I have to filesave the SAX API. Forte for Java 1.4 is available on my computer.

Thank you!

Wouldn't it be easier to write a Schema or DTD to validate the XML file?

Thank you.
But I am writting a program with user interface in Java. I want that the user opens one xml file at first and then click on a button to check the validation of this xml file.

PHP SAX has no validation; it doesn't even check well-formedness. I assume that Java SAX is the same, but I don't know for a fact.

If you need XML validation then I suggest you install an XSLT processor, such as Sablotron

But you would still need to write DTD/Schemas for them - unless I'm very much mistaken - without a DTD or Schema an XML doc can never be valid, because the validity of a document is a comparison with its definition.
