SAX: How to get hold of character references

[Jan van Mansum]

Hello group,

I have the following problem. I am trying to write an XSLT source code
formatter as an exercise. My problem is that the parser (Xalan in my
case) expands the character references (such as
for a newline).
However, I would my source code formatter to keep the character
reference unchanged. I know how to solve this problem for entity
references, but I don't know if there is a way to get hold of the
character references used.

Thanks in advance,
