The function ensures that your document is compliant with the rules defined by an associated DTD, XML Schema, Relax NG, or Schematron schema.XML Schema or Relax NG schema also allows you to embed Schematron rules.The first way is to validate the XML content using a validating Xml Reader object and the second way is to use the Validate method of the Xml Document class. An Xml Schema Exception will be thrown when an attribute or element with Typed Value set to is accessed by the XPath Navigator. The following example validates the file as it is loaded into the Xml Document object by creating the Xml Document object using a validating Xml Reader object. You can also perform read-only validation of XML content using the XPath Document class. The Validity property can be used to determine whether or not an individual attribute or element is valid when accessing attributes or elements with the XPath Navigator. The XML document is validated successfully as it is loaded without generating any schema validation errors or warnings. by Deepak Vohra 09/15/2004 An XML schema defines the structure of the elements and attributes in an XML document.For an XML document to be valid based on an XML schema, the XML document has to be validated against the XML schema.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.
To validate an XML document with the Xerces2-j parser, the Xerces2-j classes need to be in the classpath.
The element declarations in an XML Schema can specify the namespace/s of the elements in the XML document.
Using the Xml Document class, you can validate the XML content contained in an Xml Document object in two ways. If a Validation Event Handler is set on the validating Xml Reader, the Validation Event Handler will get called whenever an invalid type is encountered. Message) Exit Sub End Select End Sub End Class After modifications are made to an XML document, you can validate the modifications against the schema for the XML document using the Validate method of the Xml Document class. XPath Class Validating Reader Example Shared Sub Main(By Val args() As String) Try Dim settings As Xml Reader Settings = New Xml Reader Settings() settings.
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.
The validator will report fatal errors, non-fatal errors and warnings.
