Henrik,

I've already got a solution to the issue.  libxml-ruby has the functionalit=
y
I need.

One of my projects is SiteMap ( http://rubyforge.org/projects/sitemap )
which is a Domain Specific Language that descripts web site navigation,
access control, link names, etc.  SiteMap allows the designer to imbed Ruby
code (e.g., to test access control, etc.)  It would be nice to have the
file/line of the generated methods in stack traces, etc.

Thanks,

David
