Java validating xml against schema
However, once you learn the API for validating DOM documents against RELAX NG schemas (for instance), you can use the same API to validate JDOM documents against W3C schemas. Schema Instance(Schema Factory.java:186) at Docbook RELAXNGCheck.main(Docbook RELAXNGCheck.java:14) This isn't a closed list.For example, Listing 2 shows a program that validates Doc Book documents against Doc Book's RELAX NG schema. The only things that have changed are the location of the schema and the URL that identifies the schema language. Implementations are free to add other URLs to this list to identify other schema languages.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.*The maximum size limit for file upload is 2 megabytes.Validates the XML string/file against the specified XSD string/file.XSD files are "XML Schemas" that describe the structure of a XML document.The validator checks for well formedness first, meaning that your XML file must be parsable using a DOM/SAX parser, and only then does it validate your XML against the XML Schema.
That documentation contains more detailed, developer-targeted descriptions, with conceptual overviews, definitions of terms, workarounds, and working code examples.

package provides an API for XML documents validation.
However, it's usually done before any further processing of the input takes place.
(This description is painted with broad strokes -- there are exceptions.)Until recently, the exact Application Programming Interface (API) by which programs requested validation varied with the schema language and parser.
