Java and XML: How to get list of included files

Question

I have problem with by Xinclude or as an entity included files. I need to know, which files have been included by parser. Example:

<?xml version="1.0" ?>
<!DOCTYPE docBookChapter [
    <!ENTITY externalFile SYSTEM "entityIncluded.xml">
]>
<chapter xmlns="http://www.w3.org/1999/xhtml"
xmlns:xi="http://www.w3.org/2001/XInclude">
    <title>Third chapter</title>
    <xi:include href="xIncluded.xml"/>
    <chapter>
        &externalFile;</chapter>
</chapter>

The parser creates DOM successfully, but how to get names of files included? The element xi:include is already replaced with content of file.

How did you parse the xml? Are you using standard Java DOM parsing? — wjans, Jul 11 '11 at 07:43
Yes, I do. I create a `DocumentBuilderFactory` instance and then a document builder instance. The document builder uses Xerces. — Theodor Keinstein, Jul 11 '11 at 11:32

Extend DefaultHandler and @Overwrite the resolveEntity method. Your implementation will simply print or log the publicId/systemId and return null, so the SAXParser will use the default behaviour to resolve the entities.

Pass your DefaultHandler subclass with the SAXParser constructor.

Thanks a lot. It works. For all included files (either x-included or included as an entity) the method obtains absolute path of a file merged as the `systemId` parameter. – Theodor Keinstein Jul 11 '11 at 11:19
