GetSchemaInfo(XAttribute) GetSchemaInfo(XAttribute) GetSchemaInfo(XAttribute) GetSchemaInfo(XAttribute)

検証済み属性のスキーマ検証後の infoset (PSVI) を取得します。Gets the post-schema-validation infoset (PSVI) of a validated attribute.

GetSchemaInfo(XElement) GetSchemaInfo(XElement) GetSchemaInfo(XElement) GetSchemaInfo(XElement)

検証済み要素のスキーマ検証後の infoset (PSVI) を取得します。Gets the post-schema-validation infoset (PSVI) of a validated element.

注釈

XDocumentを検証した後、ドキュメントに含まれているXElementまたはXAttributeのスキーマ検証後の infoset を取得できます。After you have validated an XDocument, you can retrieve the post-schema-validation infoset for an XElement or XAttribute that is contained in the document.

IXmlSchemaInfoオブジェクトを取得した後は、プロパティSchemaAttributeまたSchemaElementはプロパティを使用して、部分XmlSchemaElement検証XmlSchemaAttribute型 (または) を取得できます。After retrieving the IXmlSchemaInfo object, you can use the SchemaAttribute or SchemaElement properties to get a partial validation type (XmlSchemaElement or XmlSchemaAttribute). 部分検証型を使用して、属性またはサブツリーを検証できます。You can use the partial validation types to validate an attribute or a sub-tree.

検証済みの XAttributeAn XAttribute that has been previously validated.

IXmlSchemaInfo のスキーマ検証後の infoset を含む XAttributeA IXmlSchemaInfo that contains the post-schema-validation infoset for an XAttribute.

注釈

このメソッドによっIXmlSchemaInfoて返されるを使用して、検証された属性の特定の特性を確認できます。You can use the IXmlSchemaInfo returned by this method to determine certain characteristics of a validated attribute. たとえば、属性が XSD の既定の属性値からのものかどうかを確認できます。For example, you can determine if the attribute came from a default attribute value in an XSD.

部分検証型SchemaAttribute (XmlSchemaAttribute) を取得するには、プロパティを使用します。You use the SchemaAttribute property to get a partial validation type (XmlSchemaAttribute). これを使用すると、ドキュメント全体を検証することなく、属性を再検証できます。You can use it to revalidate an attribute without validating an entire document.

このプロパティの例についてはValidate、「」を参照してください。For an example of this property, see Validate.

次の例では、PSVI を使用してツリーを設定します。The following example populates the tree with a PSVI. 検証後は、PSVI に従って無効なすべての要素と属性がツリーに出力されます。After validation, it prints all elements and attributes in the tree that are invalid according to the PSVI.

注釈

このメソッドによっIXmlSchemaInfoて返されるを使用して、検証された要素の特定の特性を確認できます。You can use the IXmlSchemaInfo returned by this method to determine certain characteristics of a validated element. たとえば、要素の動的スキーマ型を特定できます。For example, you can determine the dynamic schema type of the element.

部分検証型SchemaElement (XmlSchemaElement) を取得するには、プロパティを使用します。You use the SchemaElement property to get a partial validation type (XmlSchemaElement). これを使用すると、ドキュメント全体を検証せずに、ルートに要素があるサブツリーを再検証できます。You can use it to revalidate a sub-tree with an element at its root without validating an entire document.

このプロパティの例についてはValidate、「」を参照してください。For an example of this property, see Validate.
