❮ Complete XML Schema Reference
Definition and Usage
The include element is used to add multiple schemas with the same target namespace to a document.
Element Information
- Parent elements: schema
Syntax
<include
id=ID
schemaLocation=anyURI
any attributes
>
(annotation?)
</include>
(The ? sign declares that the element can occur zero or one time inside the include element)
| Attribute | Description |
|---|---|
| id | Optional. Specifies a unique ID for the element |
| schemaLocation | Required. Specifies the URI to the schema to include in the target namespace of the containing schema |
| any attributes | Optional. Specifies any other attributes with non-schema namespace |
Example 1
With included schemas, the included files must all reference the same target namespace. If the schema target namespace don't match, the include won't work:
<?xml version="1.0"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
targetNamespace="https://www.w3schools.com/schema">
<xs:include schemaLocation="https://www.w3schools.com/xml/customer.xsd"/>
<xs:include schemaLocation="https://www.w3schools.com/xml/company.xsd"/>
..
..
..
</xs:schema>
