ISchemaItemCollection Interface
[This feature was only implemented for MSXML 6.0.]
Stores collections of objects returned from various properties of the SOM interfaces. You can use the methods of the ISchemaItemCollection interface to search and browse these collections.
Different types of objects are returned for different interfaces. For example, elements return objects that invoke the ISchemaElement interface, attributes return objects that invoke the ISchemaAttribute interface, and so on.
The following is a list of the interface property for each property that returns an item collection.
| Property | Collection contents |
|---|---|
ISchema.types |
types |
ISchema.elements |
elements |
ISchema.attributes |
attributes |
ISchema.attributeGroups |
attribute groups |
ISchema.modelGroups |
model groups |
ISchema.notations |
notations |
ISchemaAttributeGroup.attributes |
attributes |
ISchemaElement.identityConstraints |
constraints |
ISchemaItem.baseTypes |
base types |
ISchemaComplexType.attributes |
attributes |
ISchemaModelGroup.particles |
particles |
Properties
| item | Retrieves ISchemaItem objects by the index. |
| length | Retrieves the number of schema items in the collection. |
Methods
| itemByName | Retrieves ISchemaItem objects by name. |
| itemByQName | Retrieves ISchemaItem objects by name, along with the specified QName. |
JScript Syntax
var oISchemaElements = ISchema.elements; or
