public class SchemaManager
A SchemaManager is responsible for compiling schemas and
maintaining a cache of compiled schemas that can be used for validating
instance documents.
To obtain a SchemaManager, use the
SchemaManager property of the Processor object.
In a schema-aware Processor there is exactly one
SchemaManager (in a non-schema-aware Processor there is none).
The cache of compiled schema definitions can include only one schema component (for example a type, or an element declaration) with any given name. An attempt to compile two different schemas in the same namespace will usually therefore fail.
As soon as a type definition or element declaration is used for the first time in a validation episode, it is marked as being "sealed": this prevents subsequent modifications to the component. Examples of modifications that are thereby disallowed include adding to the substitution group of an existing element declaration, adding subtypes to an existing type, or redefining components using <xs:redefine>

public String XsdVersion {get; set; }
The version of the W3C XML Schema Specification handled by this SchemaManager
The value must be "1.0" (indicating XML Schema 1.0) or "1.1" (indicating XML Schema 1.1. The default is "1.0". New constructs defined in XSD 1.1 are rejected unless this property is set to "1.1" before compiling the schema.
public SchemaResolver SchemaResolver {get; set; }
The SchemaResolver is a user-supplied class used for resolving references to
schema documents. It applies to references from one schema document to another
appearing in xs:import, xs:include, and xs:redefine; to
references from an instance document to a schema in xsi:schemaLocation and
xsi:noNamespaceSchemaLocation, to xsl:import-schema in XSLT, and to
the import schema declaration in XQuery.
public IList ErrorList {get; set; }
List of errors. The caller may supply an empty list before calling Compile; the processor will then populate the list with error information obtained during the schema compilation. Each error will be included as an object of type StaticError. If no error list is supplied by the caller, error information will be written to the standard error stream.
By supplying a custom List with a user-written add() method, it is possible to intercept error conditions as they occur.
Note that this error list is used only for errors detected during the compilation of the schema. It is not used for errors detected when using the schema to validate a source document.
| Method Detail |
|---|
public void Compile(System.IO.Stream input, System.Uri baseUri)
Compile a schema supplied as a Stream. The resulting schema components are added to the cache.
Parameters:input -
baseUri -
public void Compile(System.Uri uri)
Compile a schema, retrieving the source using a URI. The resulting schema components are added to the cache.
The document located via the URI is parsed using the System.Xml parser.
uri -
public void Compile(System.Xml.XmlReader reader)
Compile a schema, delivered using an XmlReader. The resulting schema components are added to the cache.
The XmlReader is responsible for parsing the document; this method builds a tree
representation of the document (in an internal Saxon format) and compiles it.
The XmlReader is used as supplied; it is the caller's responsibility to ensure that
its settings are appropriate for parsing a schema document (for example, that entity
references
are expanded and whitespace is retained.)
reader -
public void Compile(XdmNode node)
Compile a schema document, located at an XdmNode. This may be a document node whose
child is an xs:schema element, or it may be
the xs:schema element itself. The resulting schema components are added
to the cache.
node -
public SchemaValidator NewSchemaValidator()
Create a new SchemaValidator, which may be used for validating instance
documents.
The SchemaValidator uses the cache of schema components held by the
SchemaManager. It may also add new components to this cache (for example,
when the instance document references a schema using xsi:schemaLocation).
It is also affected by changes to the schema cache that occur after the
SchemaValidator is created.
When schema components are used for validating instance documents (or for compiling
schema-aware queries and stylesheets) they are sealed to prevent subsequent modification.
The modifications disallowed once a component is sealed include adding to the substitution
group
of an element declaration, adding subtypes derived by extension to an existing complex
type, and
use of <xs:redefine>
public XdmAtomicType GetAtomicType(QName qname)
Factory method to get an AtomicType object representing the atomic type with a given QName.
It is undefined whether two calls on this method supplying the same QName will return
the same
XdmAtomicType object instance.
qname -
AtomicType object representing this type if it is present in this schema (and is an
atomic type); otherwise, null.
