Select row from file and text
Hi all!
I would like to solve a problem but I have no clue of how do it!I will be grateful if someone could help me!
Briefly I have a big file like this:
HTML Code:
>ENSMUSG00000000204 | ENSMUST00000159637
GGCGAGGCTTACGCCATTTTACCTCAGCGAGCATTCATAAAGCTGCGAGCATTCATACAG
>ENSMUSG00000000204 | ENSMUST00000457457
CTGTCCTCTTTCCATGTGCTGTGTGAACCTGGCATGCTGGCTTAGGACATGGCCTGATTC
>ENSMUSG00000006755 | ENSMUST00000457688
GGCGAGGCTTACGCCATTTTGTGTGAACCTGGCATGCTGGCTTAGGACATGGCCTGATTC
>ENSMUSG00000037965 | ENSMUST00000068577
GGCGAGGCTTACGCCATTTTGTGTGAACCTGGCATGCTGGCTTAGGACATGGCCTGATTC
>ENSMUSG00000002323 | ENSMUST00000777544
GGCGAGGCTTACGCCATTTTGTGTGAACCTGGCATGCTGGCTTAGGACATGGCCTGATTC
and another file like this (it contains all the ID I want obtain freom the previous file!):
HTML Code:
ENSMUSG00000000204
ENSMUSG00000002323
My desired output should be like that (the selected ID and the relative sequence:
HTML Code:
>ENSMUSG00000000204 | ENSMUST00000159637
GGCGAGGCTTACGCCATTTTACCTCAGCGAGCATTCATAAAGCTGCGAGCATTCATACAG
>ENSMUSG00000000204 | ENSMUST00000457457

>ENSMUSG00000002323 | ENSMUST00000777544

html::filter
HTML::Filter(3) User Contributed Perl Documentation HTML::Filter(3)
NAME
HTML::Filter - Filter HTML text through the parser
NOTE
This module is deprecated. The "HTML::Parser" now provides the functionally of "HTML::Filter" much more efficiently with the the "default"
handler.
SYNOPSIS
require HTML::Filter;
$p = HTML::Filter->new->parse_file("index.html");
DESCRIPTION
"HTML::Filter" is an HTML parser that by default prints the original text of each HTML element (a slow version of cat(1) basically). The
callback methods may be overridden to modify the filtering for some HTML elements and you can override output() method which is called to
print the HTML text.
"HTML::Filter" is a subclass of "HTML::Parser". This means that the document should be given to the parser by calling the $p->parse() or
$p->parse_file() methods.
EXAMPLES
The first example is a filter that will remove all comments from an HTML file. This is achieved by simply overriding the comment method to
do nothing.
package CommentStripper;
require HTML::Filter;
@ISA=qw(HTML::Filter);
sub comment { } # ignore comments
The second example shows a filter that will remove any <TABLE>s found in the HTML file. We specialize the start() and end() methods to
count table tags and then make output not happen when inside a table.
package TableStripper;
require HTML::Filter;
@ISA=qw(HTML::Filter);
sub start
{
my $self = shift;
$self->{table_seen}++ if $_[0] eq "table";
$self->SUPER::start(@_);
}
sub end
{
my $self = shift;
$self->SUPER::end(@_);
$self->{table_seen}-- if $_[0] eq "table";
}
sub output
{
my $self = shift;
unless ($self->{table_seen}) {
$self->SUPER::output(@_);
}
}
If you want to collect the parsed text internally you might want to do something like this:
package FilterIntoString;
require HTML::Filter;
@ISA=qw(HTML::Filter);
sub output { push(@{$_[0]->{fhtml}}, $_[1]) }
sub filtered_html { join("", @{$_[0]->{fhtml}}) }
