RE: Default values in elements

[Radu Preotiuc-Pietro]

Yes, it is possible, but you need to be aware of a few things.

 

In XMLSchema, a default value on an element behaves differently than a default value on an attribute in that an absent element with a default value does *not* end up as an element with the default value in PSVI, but an absent attribute with a default value does show up in the PSVI (also an empty element with default value shows up as an element with that value).

 

Keeping this in mind, if you had this in your XML file

 

<parent>

<testElement/>

</parent>

 

and you did

 

parent.getTestElement()

 

then you would get "1234", the default value.

 

But if you had

 

<parent>

</parent>

 

then parent.getTestElement() would return null.

Subject: Default values in elements

Hi,

   I am new to XMLBeans. Is it possible that the generated XML Bean java objects can return a default value associated with an element in the schema?

 

For eg:

 

 

<xsd:simpleType name="mySimpleType">

<xsd:restriction base="xsd:string">

<xsd:maxLength value="4"/>

</xsd:restriction>

</xsd:simpleType>

 

<xsd:complexType name="MyComplexType">

<xsd:element name="testElement" type="tns:mySimpleType" default="1234" minOccurs="0"/>

</xsd:complexType>

So, here suppose that i don't set the testElement value in my client and send the SOAP message to a service and then on the server side when i do a getTestElement() , i would expect it to return the default value "1234". But i get a null instead.

 

Is there some setting i need to do for getting the default values.?

 

   Thanks for any help on this.
