Since HTML is very similar to XML, you may use an xml tool to parse your file.
Since your HTML-File is not fully standards compliant, the parser complains about it and the file has either be adapted by hand to be compliant or to be preprocessed prior to the parsing. The <br> is the problematic element. Compliant would be <br/> with a slash within the tag.
So you can do it with an xmlparser like xmlstarlet in three steps:
Code:
sed 's|<br>|<br/>|gi' data.html |
xmlstarlet sel -t -v '//body/div/p' |
sed -e '/^\s*$/d' -e 's/^\s*//'
1. Make the html file compliant by replacing the br-Tags
2. Get the wanted HTML-Element with xmlstarlet
3. suppress unwanted empty lines and leading whitespace in data / xmlstarlet output
I have a html file called myfile. If I simply put "cat myfile.html" in UNIX, it shows all the html tags like <a href=r/26><img src="http://www>. But I want to extract only text part.
Same problem happens in "type" command in MS-DOS.
I know you can do it by opening it in Internet Explorer,... (4 Replies)

Hi!
I have a bunch of HTML files, which I want to parse to CSV files. Every page has a table in it, and I need to parse each row into a csv record.
With awk and sed, I managed to put every table row in separate lines. So my file looks like this:
<TR> .... </TR>

html::assubs
HTML::AsSubs(3) User Contributed Perl Documentation HTML::AsSubs(3)NAME
HTML::AsSubs - functions that construct a HTML syntax tree
SYNOPSIS
use HTML::AsSubs;
$h = body(
h1("This is the heading"),
p("This is the first paragraph which contains a ",
a({href=>'link.html'}, "link"),
" and an ",
img({src=>'img.gif', alt=>'image'}),
"."
),
);
print $h->as_HTML;
DESCRIPTION
This module exports functions that can be used to construct various HTML elements. The functions are named after the tags of the
correponding HTML element and are all written in lower case. If the first argument is a hash reference then it will be used to initialize
the attributes of this element. The remaining arguments are regarded as content.
For a similar idea (i.e., it's another case where the syntax tree of the Perl source mirrors the syntax tree of the HTML produced), see
HTML::Element's "new_from_lol" method.
For what I now think is a cleaner implementation of this same idea, see the excellent module "XML::Generator", which is what I suggest for
actual real-life use. (I suggest this over "HTML::AsSubs" and over "CGI.pm"'s HTML-making functions.)
ACKNOWLEDGEMENT
This module was inspired by the following message:
Date: Tue, 4 Oct 1994 16:11:30 +0100
Subject: Wow! I have a large lightbulb above my head!
Take a moment to consider these lines:
%OVERLOAD=( '""' => sub { join("", @{$_[0]}) } );
sub html { my($type)=shift; bless ["<$type>", @_, "</$type>"]; }
:-) I *love* Perl 5! Thankyou Larry and Ilya.
Regards,
Tim Bunce.
p.s. If you didn't get it, think about recursive data types: html(html())
p.p.s. I'll turn this into a much more practical example in a day or two.
p.p.p.s. It's a pity that overloads are not inherited. Is this a bug?
BUGS
The exported link() function overrides the builtin link() function. The exported tr() function must be called using &tr(...) syntax
because it clashes with the builtin tr/../../ operator.
SEE ALSO
HTML::Element, XML::Generator
Private Functions
_elem()
The _elem() function is wrapped by all the html 'tag' functions. It takes a tag-name, optional hashref of attributes and a list of content
as parameters.
