Examples

The following example validates the contosoBooks.xml file against the contosoBooks.xsd schema. The example uses the XmlSerializer class to deserialize the contosoBooks.xml file and pass the value of the nodes to the methods of the XmlSchemaValidator class.

Remarks

Important

  • Do not use schemas from unknown or untrusted sources or locations. Doing so will compromise the security of your code.
  • XML schemas (including inline schemas) are inherently vulnerable to denial of service attacks; do not accept them in untrusted scenarios.
  • Schema validation error messages and exceptions may expose sensitive information about the content model or URI paths to the schema file. Be careful not to expose this information to untrusted callers.

The XmlSchemaValidator class provides an efficient, high-performance mechanism to validate XML data against XML schemas in a push-based manner. For example, the XmlSchemaValidator class allows you to validate an XML infoset in-place without having to serialize it as an XML document and then reparse the document using a validating XML reader. The XmlSchemaValidator class can also be used to build validation engines over custom XML data sources or as a way to build a validating XML writer.

For more information about the XmlSchemaValidator class, see the XmlSchemaValidator Push-Based Validation topic.

Important

The ProcessInlineSchema and ProcessSchemaLocation validation flags of an XmlSchemaValidator object are not set be default. Additionally, the XmlResolver property of an XmlSchemaValidator object is null by default. As a result, external schemas referenced in include, imports, or redefine elements are not resolved by default.

Constructors

XmlSchemaValidator(XmlNameTable, XmlSchemaSet, IXmlNamespaceResolver, XmlSchemaValidationFlags) XmlSchemaValidator(XmlNameTable, XmlSchemaSet, IXmlNamespaceResolver, XmlSchemaValidationFlags) XmlSchemaValidator(XmlNameTable, XmlSchemaSet, IXmlNamespaceResolver, XmlSchemaValidationFlags) XmlSchemaValidator(XmlNameTable, XmlSchemaSet, IXmlNamespaceResolver, XmlSchemaValidationFlags)

Initializes a new instance of the XmlSchemaValidator class.

Properties
