XML::XSLT does not accept an absolute path

I've run into a bug in XML::XSLT. If you give it an .xsl file by an
absolute name, it fails with the message:

Error while parsing: no element found at line 1, column 0, byte -1 at
C:/Perl/site/lib/XML/Parser.pm line 185

If you use relative path, no problems.

The line that's casuing the error is this:

my $xslt = XML::XSLT->new( $xslfile, warnings => 1, debug => 1);

There are no spaces anything else "weird" in the absolute path.
But this is on Windows, so it begins with "D:\users".

This looks like a minor omission somewhere in the module.
How can this be corrected?

Thanks,

This is what happens under the hood:

creating parser object:
opening xsl...
SOURCE = D:\users\nmw\work\udev_appver\t\portfolio.xsl
opening document
Opening URL
FILENAME 0 = D:\users\nmw\work\udev_appver\t\portfolio.xsl
FILENAME URI:
D:%5Cusers%5Cnmw%5Cwork%5Cudev_appver%5Ct%5Cportfolio.xsl
NEW FILENAME:
*** Error: Could not create an instance of the XSL Processor using
D:\users\nmw\work\udev_appver\t\p
ortfolio.xsl: Error while parsing:
no element found at line 1, column 0, byte -1 at
C:/Perl/site/lib/XML/Parser.pm line 185

So,

either XSL::XSLT is wrong by calling

URI->new_abs( $filename, $base );

or URI is wrong by returning a string that no FileHandle will be able
to open

D:%5Cusers%5Cnmw%5Cwork%5Cudev_appver%5Ct%5Cportfolio.xsl

What do you think?

Can't you use forward slashes?

D:/users/thefile.xml

No, no luck there either. Same error.

Try passing the absolute path as a file URI:
file:///D:/users/thefile.xml

Neither XML::XSLT nor URI make a distinction between
local paths and URLs as their arguments, so to satisfy
LWP::Simple's get() method, one needs to prefix with
the correct scheme.

Ah! That's the trick!..

"file:///D:\users\thefile.xsl" fixed it.

Many thanks, Chris.
