Extensions::GetSchemaInfo Method (XElement^)

 

Gets the post-schema-validation infoset (PSVI) of a validated element.

Namespace:   System.Xml.Schema
Assembly:  System.Xml.Linq (in System.Xml.Linq.dll)

public:
[ExtensionAttribute]
static IXmlSchemaInfo^ GetSchemaInfo(
	XElement^ source
)

Parameters

source
Type: System.Xml.Linq::XElement^

An XElement that has been previously validated.

Return Value

Type: System.Xml.Schema::IXmlSchemaInfo^

A IXmlSchemaInfo that contains the post-schema-validation infoset (PSVI) for an XElement.

You can use the IXmlSchemaInfo returned by this method to determine certain characteristics of a validated element. For example, you can determine the dynamic schema type of the element.

You use the SchemaElement property to get a partial validation type (XmlSchemaElement). You can use it to revalidate a sub-tree with an element at its root without validating an entire document.

For an example of this property, see Validate.

The following example populates the tree with a PSVI. After validation, it prints all elements and attributes in the tree that are invalid according to the PSVI.

No code example is currently available or this language may not be supported.

This example produces the following output:

Validating doc1 ...
The 'GrandChild2' element is invalid - The value 'ZZZ' is invalid according to its datatype 'GCType' - The Enumeration constraint failed.
The 'GrandChild3' element is invalid - The value 'ZZZ' is invalid according to its datatype 'GCType' - The Enumeration constraint failed.
doc1 did not validate
Invalid Element /Root
Invalid Element /Root/Child1
Invalid Element /Root/Child1/GrandChild2
Invalid Element /Root/Child1/GrandChild3
