    • validateDocument

      public List<SAXParseException> validateDocument(Node node, String schemaAlias) throws IOException, SAXException
      Validates the document loaded into node against the schema mapped to schemaAlias. Note that a more complete validation can be performed by using a Source instead of a Node, as fatal errors will already be raised when parsing the text into a DOM tree.
      Parameters:
      node - the XML document to validate
      schemaAlias - the alias of the schema to validate against
      Returns:
      a list of SAXParseExceptions encountered during validation; an empty list indicates the document is valid
      Throws:
      IOException - if the schema cannot be read
      SAXException - if validation could not be performed

      source - the XML document to validate

      Returns:
      a list of SAXParseExceptions encountered during validation; an empty list indicates the document is valid
