Статья
10/27/2016

[This feature was only implemented for MSXML 6.0.]

Returns information about all the individual items in an XML Schema. The itemByName and itemByQName methods of the ISchemaItemCollection interface return the ISchemaItem objects. The information provided by the ISchemaItem interface is top-level. To obtain more information about the item, use the other interfaces in the SOM. For a list of these interfaces, see the SOM Reference overview.

Example

The following is an example of an XML Schema document with some schema items and the properties obtained from ISchemaItem.

<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"  
            xmlns:pub="http://www.lucernepublishing.com/fake/schema">  
  <xsd:element name="book">  
    <xsd:complexType>  
      <xsd:attribute name="booktitle"/>  
    </xsd:complexType>  
  </xsd:element>  
</xsd:schema>
