Element Information
- Parent elements: simpleType
Syntax
<list
id=ID
itemType=QName
any attributes
>
(annotation?,(simpleType?))
</list>
(The ? sign declares that the element can occur zero or one time inside the list element)
| Attribute | Description |
|---|---|
| id | Optional. Specifies a unique ID for the element |
| itemType |

| any attributes | Optional. Specifies any other attributes with non-schema namespace |
Example 1
The following example shows a simple type that is a list of integers:
<?xml version="1.0"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="intvalues" type="valuelist"/>
<xs:simpleType name="valuelist">
<xs:list itemType="xs:integer"/>
</xs:simpleType>
</xs:schema>
The "intvalues" element in a document could look like this (notice that
the list will have five list items):
<intvalues>100 34 56 -23 1567</intvalues>
Note: White space is treated as the list item separator!
Example 2
The following example shows a simple type that is a list of strings:
<?xml version="1.0"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="stringvalues" type="valuelist"/>
<xs:simpleType name="valuelist">
<xs:list itemType="xs:string"/>
</xs:simpleType>
</xs:schema>
The "stringvalues" element in a document could look like this (notice
that the list will have four list items):
<stringvalues>I love XML Schema</stringvalues>
