XmlSchemaValidator Constructor
Initializes a new instance of the XmlSchemaValidator class.
Assembly: System.Xml (in System.Xml.dll)
public XmlSchemaValidator(
XmlNameTable nameTable,
XmlSchemaSet schemas,
IXmlNamespaceResolver namespaceResolver,
XmlSchemaValidationFlags validationFlags
)
Parameters
- nameTable
- Type: System.Xml.XmlNameTable
An XmlNameTable object containing element and attribute names as atomized strings.
- schemas
- Type: System.Xml.Schema.XmlSchemaSet
An XmlSchemaSet object containing the XML Schema Definition Language (XSD) schemas used for validation.
- namespaceResolver
- Type: System.Xml.IXmlNamespaceResolver
An IXmlNamespaceResolver object used for resolving namespaces encountered during validation.
- validationFlags
- Type: System.Xml.Schema.XmlSchemaValidationFlags
An XmlSchemaValidationFlags value specifying schema validation options.
| Exception | Condition |
|---|---|
| ArgumentNullException |
One or more of the parameters specified are null. |
| XmlSchemaException |
An error occurred while compiling schemas in the XmlSchemaSet parameter. |
The following are important notes to consider when using the XmlSchemaValidator constructor.
-
The contents of the XmlSchemaSet parameter are copied into an internal XmlSchemaSet object when the ProcessInlineSchema or the ProcessSchemaLocation validation options are set. As a result, changes to the input XmlSchemaSet object during validation do not affect the outcome of validation.
-
If the XmlSchemaSet parameter specified is not compiled, its Compile method is called.
-
The IXmlNamespaceResolver parameter is especially important for validating xs:QName types. The XmlSchemaValidator class does not copy the in-scope namespaces from the IXmlNamespaceResolver object but instead holds a reference to it. This allows new namespaces to be added to the IXmlNamespaceResolver object during the validation process.
Security Note

|
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. |
For an example of the XmlSchemaValidator constructor, see the XmlSchemaValidator class reference topic.
