The XML schema generated

XML

DAPTER

FIELD

XAMPLE

<xs:element name="key" minOccurs="0"
type="xs:anyType"/>
<xs:element name="value" minOccurs="0"
type="xs:anyType"/>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>

In the default HashMap schema, key and value are both elements and are of
datatype

anyType

. The XML content will look like this:

<basket>
<entry>
<key>9027</>
<value>glasstop stove in black</>
</entry>
<entry>
<key>288</>
<value>wooden spoon</>
</entry>
</basket>

To resolve this issue, we wrote two Java classes,

PurchaseList

and

PartEntry

that reflect the needed schema format for unmarshalling/marshalling the content.
The XML schema generated for these classes is as follows:

<xs:complexType name="PurchaseListType">
<xs:sequence>
<xs:element name="entry" type="partEntry"
nillable="true" maxOccurs="unbounded"
minOccurs="0"/>
</xs:sequence>
</xs:complexType>

<xs:complexType name="partEntry">
<xs:simpleContent>
<xs:extension base="xs:string">
<xs:attribute name="key" type="xs:int"
use="required"/>
</xs:extension>
</xs:simpleContent>
</xs:complexType>
