The Perl Cookbook has a good example:
#!/usr/local/bin/perl # xurl - extract unique, sorted lists of links from URL use HTML::LinkExtor; use LWP::Simple; $base_url = shift; $parser = HTML::LinkExtor->new(undef, $base_url); $parser->parse(get($base_url))->eof; @links = $parser->links; foreach $linkarray (@links) { local(@element) = @$linkarray; local($elt_type) = shift @element; while (@element) { local($attr_name, $attr_value) = splice (@element, 0, 2); $seen{$attr_value}++; } } for (sort keys %seen) { print $_, "\n"}
Hope this helps. /msg me if you need anything else.

[GrandFather]: HI jedikaiti. Collected more 73p data this morning. Rubbish sky though. Seeing was between 5 and 9 arc seconds FWHM with thin cloud drifting through :(
[GrandFather]: Still, at least some of the images are good enough to get reasonable astrometry. Well, good enough for a good plate solve anyway
