Here is how I have implemented the SAX 2.0 Locator interface:
Entity being parsed Event Sysid reported by locator
------------------- ----------------- ------------------------
Document startElement Document
Document startEntity Foo Document
Foo startElement Foo
Foo endElement Foo
Document entEntity Foo Document
At the startEntity and endEntity events, the locator also reports the line
and column numbers of the entity reference in the source document. My main
concern was error reporting: if an error occurs at or about an entity
reference, I wanted the locator to aid in troubleshooting.
If you have the locator return the system identifier of the
referenced entity, what would the line and column numbers be? 0 and 0?
Note though that a similar problem occurs with startDocument() and
endDocument(), in that it isn't clear what are the line number and column
number of such a "threshold event."
