Question

I’m reading an xml file using Jaxb, now the contents of the xml file are increasing and the file is becoming too cumbersome to maintain, is there any way I can modularize the xml, by splitting it into multiple files? Is there anyway to do this in a simpler way in jaxb ?

Answer 1

Well, yo could use the tried-and-true (yet much-disliked) ENTITY method in your XML file, e.g.

<!DOCTYPE config [
  <!ENTITY subpart1 SYSTEM 'config_subpart1.xml'>
  <!ENTITY subpart2 SYSTEM 'config_subpart2.xml'>
]>
<config>
    <!-- some top-level config items in the main file
    <item1>value</item1>
    ...
    <!-- then the external parts -->
    &subpart1;
    ...
    &subpart2;
    ...
</config>

The XML document is technically identical, and your JAXB code should work without any difference.
