      to validate some XML that contains or references an accessible DTD or schema
    • new Validator(readerForXML, systemIdForValidation);
      to validate some XML that references a DTD but using a local systemId to perform the validation

    • Constructor Detail

      • Validator

        protected Validator​(InputSource inputSource,
                    String systemId,
                    boolean usingDoctypeReader)
        Baseline constructor: called by all others
        Parameters:
        inputSource - document to validate
        systemId - system id of the DTD to use during validation
        usingDoctypeReader - whether to use DoctypeReader

      • Validator

        public Validator​(Document document,
                 String systemID,
                 String doctype)
        DOM-style constructor: allows Document validation post-manipulation of the DOM tree's contents. This takes a fairly tortuous route to validation as DOM level 2 does not allow creation of Doctype nodes. The supplied systemId and doctype name will replace any Doctype settings in the Document.
        Parameters:
        document - document to validate
        systemID - system id of the DTD to use during validation
        doctype - overrides the document's doctype

      • Validator

        public Validator​(Reader readerForValidation)
        Basic constructor. Validates the contents of the Reader using the DTD or schema referenced by those contents.
        Parameters:
        readerForValidation - document to validate

      • Validator

        public Validator​(String stringForValidation)
        Basic constructor. Validates the contents of the String using the DTD or schema referenced by those contents.
        Parameters:
        stringForValidation - document to validate

      • Validator

        public Validator​(InputSource sourceForValidation)
        Basic constructor. Validates the contents of the InputSource using the DTD or schema referenced by those contents.
        Parameters:
        sourceForValidation - document to validate

      • Validator

        public Validator​(Reader readerForValidation,
                 String systemID)
        Extended constructor. Validates the contents of the Reader using the DTD specified with the systemID. There must be DOCTYPE instruction in the markup that references the DTD or else the markup will be considered invalid: if there is no DOCTYPE in the markup use the 3-argument constructor
        Parameters:
        readerForValidation - document to validate
        systemID - system id of the DTD to use during validation

      • Validator

        public Validator​(String stringForValidation,

        Extended constructor. Validates the contents of the String using the DTD specified with the systemID. There must be DOCTYPE instruction in the markup that references the DTD or else the markup will be considered invalid: if there is no DOCTYPE in the markup use the 3-argument constructor
        Parameters:
        stringForValidation - document to validate
        systemID - system id of the DTD to use during validation

      • Validator

        public Validator​(InputSource sourceForValidation,

        Parameters:
        sourceForValidation - document to validate
        systemID - system id of the DTD to use during validation

        Full constructor. Validates the contents of the InputSource using the DTD specified with the systemID and named with the doctype name.

    • Method Detail

      • useXMLSchema

        public void useXMLSchema​(boolean use)
        Turn on XML Schema validation.

        This feature should work with any XML parser that is JAXP 1.2 compliant and supports XML Schema validation.

        For a fully JAXP 1.2 compliant parser the property http://java.sun.com/xml/jaxp/properties/schemaLanguage is set, if this fails the method falls back to the features http://apache.org/xml/features/validation/schema & http://apache.org/xml/features/validation/dynamic which should cover early versions of Xerces 2 as well.

        Parameters:
        use - indicate that XML Schema should be used to validate documents.
        See Also:
        setJAXP12SchemaSource(Object)

      • isValid

        public boolean isValid()
        Perform the validation of the source against DTD / Schema.
        Returns:
        true if the input supplied to the constructor passes validation, false otherwise

      • assertIsValid

        public void assertIsValid()
        Assert that a document is valid.

      • toString

        public String toString()
        Overrides:
        toString in class Object
        Returns:
        class name appended with validation messages

      • setJAXP12SchemaSource

        public void setJAXP12SchemaSource​(Object schemaSource)
        As per JAXP 1.2 changes, which introduced a standard way for parsers to support schema validation. Since only W3C Schema support was included in JAXP 1.2, this is the only mechanism currently supported by this method.
        Parameters:
        schemaSource - This can be one of the following:
        • String that points to the URI of the schema
        • InputStream with the contents of the schema
        • SAX InputSource
        • File
        • an array of Objects with the contents being one of the types defined above. An array of Objects can be used only when the schema language has the ability to assemble a schema at runtime. When an array of Objects is passed it is illegal to have two schemas that share the same namespace.
