perlmad has asked for the wisdom of the Perl Monks concerning the following question:
Hi Monks
I am using www::mechanize module to parse the webpage and get the html content by HTML::TreeBuilder
here is my code
$mech -> get($home_url); print " base is :",$mech->response()->base,"\n\n"; #print " Home page is :",$mech->uri(),"\n\n"; my $parser = HTML::TokeParser->new($mech->content); html_table_parse(); sub html_table_parse { while( my $div =$parser->get_tag('div') ) { my $div_id=$div->get_attr('id'); next unless defined ($div_id) and $div_id eq 'jqxgrid'; my $div_contenttablejqxgrid=$parser->get_tag('div'); my $div_contenttablejqxgrid_id=$div_contenttablejqxgrid +->get_attr('id'); next unless defined ($div_contenttablejqxgrid_id) and $ +div_contenttablejqxgrid_id eq 'contenttablejqxgrid'; my $div_row=$parser->get_tag('div'); my $div_row_id=$div_row->get_attr('role'); next unless defined ($div_row_id) and $div_row_id eq 'r +ow'; my $div_gridcell=$parser->get_tag('div'); my $div_gridcell_id=$div_gridcell->get_attr('role'); next unless defined ($div_gridcell_id) and $div_gridcel +l_id eq 'gridcell'; print "Content is ",$div_gridcell_id->get_text,"\n\n"; } }
The problem is there is no div tag 'jqxgrid' and 'contenttablejqxgrid' and 'role' is found in the html content and end of the html content has lot of java script files they are
</script> ^M <script type="text/javascript" src="/js/jqwidgets/jqxcore.js"></s +cript> <script type="text/javascript" src="/js/jqwidgets/jqxdata.js"></s +cript> <script type="text/javascript" src="/js/jqwidgets/jqxbuttons.js"> +</script> <script type="text/javascript" src="/js/jqwidgets/jqxscrollbar.js +"></script> <script type="text/javascript" src="/js/jqwidgets/jqxmenu.js"></s +cript> <script type="text/javascript" src="/js/jqwidgets/jqxlistbox.js"> +</script> <script type="text/javascript" src="/js/jqwidgets/jqxdropdownlist +.js"></script> <script type="text/javascript" src="/js/jqwidgets/jqxcheckbox.js" +></script> <script type="text/javascript" src="/js/jqwidgets/jqxgrid.js"></s +cript> <script type="text/javascript" src="/js/jqwidgets/jqxgrid.sort.js +"></script> <script type="text/javascript" src="/js/jqwidgets/jqxgrid.filter. +js"></script> <script type="text/javascript" src="/js/jqwidgets/jqxgrid.selecti +on.js"></script> <script type="text/javascript" src="/js/jqwidgets/jqxgrid.columns +resize.js"></script> <script type="text/javascript" src="/js/jqwidgets/jqxgrid.pager.j +s"></script> <script type="text/javascript" src="/js/jqwidgets/jqxcalendar.js" +></script> <script type="text/javascript" src="/js/jqwidgets/jqxdatetimeinpu +t.js"></script> <script type="text/javascript" src="/js/jqwidgets/jqxdata.export. +js"></script> <script type="text/javascript" src="/js/jqwidgets/jqxgrid.export. +js"></script> <script type="text/javascript" src="/js/jqwidgets/jqxgrid.sort.js +"></script> <script type="text/javascript" src="/js/auctionQuery.js"></script +> </body>^M </html> </script>
Questions: 1) How to get the div tag element ? , 2) How to work javascript with perl while webpage parsing ?, 3) Is this possible to disable java script ?,
Please help me to find how to proceed with it
