in reply to use XML::LibXML; is causing compile error

I tried it myself this morning.

Only code:

use XML::LibXML;

Result:
Can't locate XML/LibXML/Common.pm in @INC (@INC contains: C:/Perl/site/lib C:/Perl/lib .) at :/Perl/site/lib/XML/LibXML.pm line 12. BEGIN failed--compilation aborted at C:/Perl/site/lib/XML/LibXML.pm line 12. Compilation failed in require at test_LibXML.pl line 3. BEGIN failed--compilation aborted at test_LibXML.pl line 3.

This is the line in LibXML.pm that causes the error:
use XML::LibXML::Common qw(:encoding :libxml);
Which is not surprising of course. I looked in C:\Perl\site\lib\XML\LibXML and the Common.pm is (of course) missing. Apparently the ppm package for Win32 from ActiveState is flawed.

Next I installed the ppm for Common separately. This took care of the problem.... but then the next problem popped up:-(

Update

Code used (taken from the pod)

use strict;
use warnings;

use XML::LibXML;

  my $parser = XML::LibXML->new;
  open my $fh, "dHarry.xml";
  binmode $fh; # drop all PerlIO layers possibly created by a use open
+ pragma
  my $doc = $parser->parse_fh($fh);
  open my $out, "out.xml";
  binmode $fh; # as above
  $doc->toFh($fh);
  # or
  print $fh $doc->toString();

Error message: Can't locate object method "toFh" via package "XML::LibXML::Document". Which makes a lot of sense since the sub is not in LibXML.pm where it should be. This wrong as it was added in v1.53 and my version is 1.66.

The ppm package from ActiveState is buggy. As an alternative you can try build it from the CPAN distribution or find another Win32 ppm package for it.

Update 2

Submitted the bug to ActiveState.

Update 3

I tried the trouchelle ppm package. First you have to install Common separately because it's not present on trouchelle. The code above gives the following error message: 

Can't load 'C:/Perl/site/lib/auto/XML/LibXML/LibXML.dll' for module XM
+L::LibXML: load_file:The specified procedure could not be found at C:

So now we're back at Problems installing XML::LibXML for Perl5.10 on Win32 platform with the remark that it's the same s*** for Per5.8.8.

    1. I'd notify ActiveState. 2. http://kobesearch.cpan.org/dist/XML-LibXML lists 

    Win32 PPM packages for "XML-LibXML"
tcool.org Perl 5.8 repository   [  v 1.66   ]
trouchelle.com Perl 5.8 repository   [  v 1.66   ]
uwinnipeg Perl 5.10 repository   [  v 1.65   ]
uwinnipeg Perl 5.6 repository   [  v 1.64   ]
uwinnipeg Perl 5.8 repository   [  v 1.64   ]

    I tried the trouchelle ppm package

    Did you try the versions at the uwinnipeg reps (1.65 for perl-5.10, 1.64 for perl-5.8) ?

        Could be worth a try.

        Earlier you reported the error Can't load 'C:/Perl/site/lib/auto/XML/LibXML/LibXML.dll' for module XML::LibXML: load_file:The specified procedure could not be found ..

        That's fairly typical of what happens when your XML C library doesn't provide the required symbols (eg, because it's too old). So ... if the trouchelle rep provides the opportunity to download an XML dll, you should probably accept the offer. Or, you should try the uwinnipeg version which, I'm confident, will provide you with the offer to download any other pre-requisites. (The trouchelle rep is usually reliable in this regard, too.)

        If the XML::LibXML binaries that you're using expect a certain set of symbols from the XML C library, then there's little point in providing a C library that doesn't provide those symbols (functions).

        Cheers,
        Rob
