Rick Hillegas updated DERBY-4415:
---------------------------------
Attachment: XmlASTPrinter.java
Attaching a new version of the XML tree printer. This makes the following
improvements:
1) Moves the phase marker (parse/bind/optimize) into an attribute so that, when
a tree is collapsed, you can see at a glance what compilation phase it belongs
to. This helps you quickly browse to the right tree.
2) Replace angle brackets in text strings with the corresponding xml entities
so that the browser doesn't choke on these strings.
> Make it easy to plug custom AST printers into the compiler

> It would be nice to be able to tell the compiler to use user-written
> formatters for pretty-printing Derby's abstract syntax trees. For instance,
> it would be nice to be able to plug in the AST printers attached to
> DERBY-791, including the Eclipse-based tree grapher written by Kay Röpke.
