property files and character encodings

property files and character encodings

[Anthony Green]

I just figured out why the xalan xsl transformer isn't running.  It's
reading property files (either compiled in, or from disk) which
contain text like this...

# Note that the colon after the protocol needs to be escaped.
{http\u003a//xml.apache.org/xslt}indent-amount=0
{http\u003a//xml.apache.org/xslt}content-handler=org.apache.xalan.serialize.SerializerToHTML
{http\u003a//xml.apache.org/xslt}entities=HTMLEntities.res
{http\u003a//xml.apache.org/xslt}use-url-escaping=yes
{http\u003a//xml.apache.org/xslt}omit-meta-tag=no


Note the escape sequence for `:'.

The program then tries to search this resource bundle for
"{ http://xml.apache.org/xslt}content-handler" ; and doesn't find a
match.  The problem is that \u003a isn't being converted into `:' when
read from a property file.  I don't know what the right solution is.
Advice welcome...

Thanks,

AG

This is a bug in java.util.Properties.load().  I'm testing a fix.
I'll check it in if it passes my tests.

I came up with a patch of my own.  Can I just check this in?

I just checked in my patch, which is a superset of this one.
There's another case lower down with the same problem.

Great!  Thanks!

With this change I am able to perform xsl translations with Xalan. I've
compiled org.apache.xalan.xslt.Process into a program, xsltp, which reads XML
and XSL files to generate appropriate output (like HTML).

xsltc is another program which compiles XSL files into .class files which may
be compiled with gcj and linked with the Xalan runtime to perform similar
translations.

Xalan is huge - so the fact that we can build and run it is an important
milestone in gcj's development.

Thanks!
