Message-ID: <E97B4331B4C19943B69A80E15DE45C2603244E92@mail1.agso.gov.au>

Hi,

I am running this little script:

#!/usr/local/bin/perl
#####################
# Tests the HTML::Extor package
#####################
use Data::Dumper;
use HTML::LinkExtor;
use LWP::Simple;

 $LX = HTML::LinkExtor->new();
 $input = q{If <a href="http://perl.com/"> I am a LINK!!! </a>};
 print "Parsing output = \n", Dumper($LX->parse($input));
 print "Linking output = \n", Dumper($LX->links);
####################
# End script
####################

and I get the following output:

marl:/public/asddadm/test$ ./linkextortest.pl
Parsing output =
$VAR1 = bless( {
                 'extractlink_cb' => undef,
                 '_hparser_xs_state' => \1030704
               }, 'HTML::LinkExtor' );
Linking output =
marl:/public/asddadm/test$

It seems to me that the HTML::LinkExtor->parse is not working.  Does anyone
know how to check this and maybe what the problem is?

Thanks.

Hi,

I have been able to get this working on another machine.  It seems that there
is a bootstrap error as follows:

HTML::Parser object version 3.25 does not match bootstrap parameter 3.26 at
/usr
/local/lib/perl5/5.6.1/sun4-solaris/DynaLoader.pm line 225.
Compilation failed in require at
/public/data/asddgate/lib/perl5.6.1/sun4-solari
s/HTML/LinkExtor.pm line 26.

Does this mean that I need to recompile DynaLoader, HTML::Parser or
HTML::LinkExtor?

This may fix my problem below.

Thanks.


John

If perl is running 'normal' programs, then dynaloader is working.  It's 
used for a few core modules, so it is pretty easy to tell.

However I do notice that you appear to be using two different versions 
of perl - one in /usr/local, one in /public.  The error is thrown in 
dynaloader while it is attempting to load HTML::LinkExtor. 

I suggest trying to either:  run the version of perl in /public or 
recompile/reinstall  HTML::LinkExtor using the perl you have installed 
in /usr/local.

The bizarre thing here is that the program ran at all...

Hi all,

Sorry I didn't get back to you earlier.  I was in Brisbane on Friday.

I think that I have found the problem.  It would appear that there wasn't a
Parser.so file in ...../site_perl/auto/HTML/Parser/Parser.so and
...../sun4-solaris/auto/HTML/Parser/Parser.so.  I have copied these files
back to the machine that was causing the error and it seems to be working
now.  

It was caused by a problem with rsync using the --cvs-exclude option not
copying .so files.  Hence the .so files were not copied from the test machine
to the master machine after the successful build and testing on the test
machine.

Thanks to all who replied to my email.

Subject: [Canberra-pm] Equivalent to PHP's var_dump()?
Message-ID: <20050118085951.GS9803@daedalus.andrew.net.au>

Here's a question that just popped into my head...

I really like PHP's var_dump() for when I'm playing with random data
structures that I don't have a clear handle on the structure of. It allows
me to visually get that handle on it. I miss this when I'm doing stuff in
Perl. 

Is there some way of doing the same sort of thing?

regards

Andrew

Indeed there is.  It's a staple for perl programmers, you'll often see 
it in code:

#!/usr/bin/perl

use Data::Dumper;
print Dumper $x;


It can also do clever tricks like serialise complex data structures.
