parsing html in Perl [CLOSED]

+1 vote
27 views

What would be the best module available for parsing html?
My intention is to parse html that contains a table of 5 columns and any number of rows, and have a hash ref like $html->{1}->{col1}=data11, $html->{1}->{col2}=data12 ...$html->{2}->{col1}=data21, $html->{2}->{col2}=data22...etc
Would there be an existing module that can do this without too much effort on my part?

For parsing HTML tables, you want HTML::TableExtract, IMO.
https://metacpan.org/module/HTML::TableExtract

It makes life easy.

Have a look at HTML::PARSER.

As I understand, Perl has excellent report-generation capabilities. By using formats, we can actually visualize how our output will look because the definition of a format in Perl is very similar to what you see on the output. Is there any way we to convert these formats into HTML reports? My goal is to create good looking HTML reports. Please suggest/advice.
