Hi,
The idea is to do away with the need to repeat a certain bolck of XML tags by putting them into a sperate file and including the same by means of a single tag .
The same XML file which is an XML instance in this case is given to the castor tool to be unmarshalled.
In case i incorporate the above in a mapping file as suggested by you.....how do i do away with hardcoding of the block of xml tags.
The input to the castor is the XML instance which i define based on the business needs.So the XML instance is not to be generated but to be provided as an input.
We have a set of class descriptor classes which take care of the unmarshalling.
Thus when i use the <include href/> the castor throws an exception saying the inlcude tag is undefined in the descriptor.
If i am not mistaken an XML instance is require for unmarshalling and not the mapping file.
Mapping file would define the underlying structure for an XML instance but still there is a need for an XML instance to be provided since i am only using the unmarshalling facility.
My query was more to probe into the possibility of the w3c having a predefined tag which allows inclusion of an external XML file.
One possibility was to define the entity in the DTD and use the same in the XML document, but this is not feasible in our environment.
Kindly suggest......if it is possible with an mapping file as u suggeted in your previous mail, please explain the details in the above context.
In short, i woud be writing an XML document and giving to castor and i want to do away with the need to hardcode the block of repeating XML tags.
Regds,
Chetan
