Hi, I'm looking for guidance on the best approach to handling multiple,
alternating, namespaces in jibx. The tutorial hints at a solution:
http://jibx.sourceforge.net/binding/tutorial/binding-advanced.html
"...This makes the namespace automatically apply to every name
definition unless you override it with a specific namespace using the ns
attribute...."
but provides no example. Try as I might, I keep getting validation
errors whatever permutation of attributes I go for!
The problem XML is long and tedious with five different namespaces all
interspersed! To illustrate the problem, consider the following
fragment:
...
<metadata>
<ns1:Product xsi:schemaLocation="http://earth.esa.int/geca
./xsd/geca/geca.xsd" xmlns:ns1="http://ns1 <http://ns1/> "
xmlns:ns2="http://ns2 <http://ns2/> ">
<ns2:metaDataProperty>
<ns1:ProductMetaData>
<ns1:fileIdentifier>urn:x-geca:avdc:500</geca:fileIdentifier>
...
If the <ns2:metaDataProperty> is simply removed, then the following
works:
...
<mapping name="Product" class="com.myCode.xxxProductFile">
<namespace name="ns1" uri="http://ns1 <http://ns1/> "
default="elements"/>
<structure name="ProductMetaData">
<value name="fileIdentifier" field="fileId"/>
...
Logically, I would expect a something like:
...
<mapping name="Product" class="com.myCode.xxxProductFile">
<namespace name="ns1" uri="http://ns1 <http://ns1/> "
default="elements"/>
<namespace name="ns2" uri="http://ns2 <http://ns2/> "
default="none"/>
<structure ns="ns2" name="metaDataProperty">
<structure name="ProductMetaData">
<value name="fileIdentifier" field="fileId"/>
...
or
...
<mapping name="Product" class="com.myCode.xxxProductFile">
<namespace name="ns1" uri="http://ns1 <http://ns1/> "
default="none"/>
<namespace name="ns2" uri="http://ns2 <http://ns2/> "
default="none"/>
<structure ns="ns2" name="metaDataProperty">
<structure ns="ns1" name="ProductMetaData">
<value ns="ns1" name="fileIdentifier" field="fileId"/>
...
to do the trick - but they both lead to compilation errors ("Namespace
prefix conflict for namespace element").
Is there a "right" approach to alternating namespaces in this manner?
All help would be much appreciated!
