Validating xml file against xsd
I then downloaded Oxygen XML editor and it worked fine on the same XML and XSD files, so the files seem to be fine (or Oxygen is more forgiving / flexible . To define the namespace: In the XML file's root element: I had this same problem, but VS was referencing my schema correctly already.
Turns out the file I was trying to validate didn't have an 'xml' file extension.
From the javadocs: "If you create a schema without specifying a URL, file, or source, then the Java language creates one that looks in the document being validated to find the schema it should use.
But sometimes it's convenient to be able to have a custom resolver...
Alternatively if you use Stax for writing content (or a library that uses or can use stax), Woodstox can also directly support validation when using XMLStream Writer.
Here's a blog entry showing how that is done: If you are generating XML files programatically, you may want to look at the XMLBeans library.
I have an XML document and a directory full of XSD's that define it.I tried both 20 (I've done it before in 2008 I thought) Update: I had another developer try this and it failed for him too.He knows he has done it with other XML documents and had it work. ) You don't need to manually associate the files in Visual Studio - it will automatically match an XML file to a XSD file if you have them both open, and you have your namespace defined correctly.W3C_XML_SCHEMA_NS_URI); Schema schema = schema Schema(); Validator validator = Validator(); Resource Resolver(new LSResource Resolver() ); validator.validate(xml File); // parse an XML document into a DOM tree Document Builder parser = Document Builder Instance()Document Builder(); Document document = parser.parse(new File("instance.xml")); // create a Schema Factory capable of understanding WXS schemas Schema Factory factory = Schema Instance(XMLConstants.W3C_XML_SCHEMA_NS_URI); // load a WXS schema, represented by a Schema instance Source schema File = new Stream Source(new File("my Schema.xsd")); Schema schema = Schema(schema File); // create a Validator instance, which can be used to validate an instance document Validator validator = Validator(); // validate the DOM tree try catch (SAXException e) It validates against dtd and xsd.
