However, you might consider asking in the chatterbox first (if you're a registered user). The response time tends to be quicker, and if it turns out that the problem/solutions are too much for the cb to handle, the kind monks will be sure to direct you here.

intersection of scalar with 1D array and 2D array Matlab=>Perl

    I'm converting some Matlab code into perl. Here's the Matlab code.

    while ~feof(fileIDS); m1=fgetl(fileIDS); [a,b]=intersect(dataD{1},{deblank(m1)}); if (~isempty( a)) data=dataD{2}(b); elseif(~isempty(intersect(dataT{1},{deblank(m1)})) ) data=1.0; else data=0.0; end; end;

    dataD is a 2D array, dataT is a 1D array

    m is a scalar value read from a file

    a=returns index if there is one and null if it doesn't and b=value at index a

    Basically what this does is the following

    intersection (2D data,scalar) if intersection exists not null a=index of location data= value of location at b elseif intersection (1D data,scalar) data=1.0 else data=0.0 endif

    I'm reading through this but this assumes that the arrays are of equal dimensions (1D).

    I'd like to know what is the simplest and fastest way?

    use 5.12.0; use strict; use warnings; use diagnostics; use List::MoreUtils; open my $TEST, '<', $f_Test or die "Could not open=> $f_Test : $!"; my $data; while (my $scalar=<$TEST>) { chomp($scalar); [my $a, my $b]=firstidx { $_ == $scalar } @arrayPFA; if(!exists $a) { $data=$arrayPFA[$b]; } elsif(if any { ! defined($scalar) } @arrayT;) { $data=1.0; } else { $data=0.0; }; }; close $TEST

    Thanks for any help.

Error hash declaration

    A fairly simple code to load a file into a hash of keys and values. I declared my hash before the while loop globally, but when I try to use $hashofstates->($key) = $val; it throws me an error as if it wasnt declared. What could possibly be wrong?

    use strict; use warnings; use Data::Dumper; my $File = "inp.txt"; open FILE, '<' , $File or die $!; my %hashofstates; while (my $line=<FILE>) { chomp $line; my ($key, $val) = split /\s+/, $line ,2; $hashofstates->($key) = $val; } close FILE or die 'Could not close file'; print (values \%hashofstates);

Digging through HTML Formatting with HTML::TagParser

    I've been trying to use HTML::TagParser to pull reviews from Yelp and modifying formatting slightly to post on our website, though I'm having difficulty parsing through child nodes of the HTML. So I started a basic html file to play with, and still having some difficulty getting the beginning and ending tags to encapsulate properly with inner-text. Here's the basic version of my HTML
    <table> <tr id="row1"> <td><div id="r1d1"><b>Test11</b></div></td> <td><div id="r1d2"><i>Test12</i></div></td> <td><div id="r1d3">test13</div></td> <td><b>test14</b></td> </tr> <tr id="row2"> <td><div id="r2d1"><b><em>Test21</em></b></div></td> <td>2</td> <td>3</td> <td>4</td> </tr> </table>
    and my code, which pulls things out of place since I can't seem to get my mind to grasp the structuring correctly. Certainly I'm missing something about the "parentNode" after a "childNode" is found... and perhaps "nextSibling" can be useful somewhere.
    #!/usr/bin/perl use strict; use CGI ':standard'; use HTML::TagParser; my @Body; my $html=HTML::TagParser->new('table.txt'); my @elem=$html->getElementsByTagName("table"); foreach my $parent(@elem){ my $text=$parent->innerText(); my $tag=$parent->tagName; my $get=$parent->childNodes(); if (@$get){push @Body,digChild(@$get);} push @Body,"<$tag>$text</$tag>"; } #foreach parent print header,start_html('table'); print join("\n",@Body)."\n"; print end_html; sub digChild { my @ar=@_; foreach my $row(@ar){ my $tag=$row->tagName; my $txt=$row->innerText; my $c=$row->childNodes(); if (@$c){push @Body,digChild(@$c);} return "<$tag>$txt</$tag>"; } # foreach row } # sub
    Thank you.

Need to send an email through my SMTP server using Perl

    So like the title says, I need to send an email via my SMTP server. It's just a simple test email designed to verify the SMTP server is active and doing its job. Here's what I have so far (with email addresses removed):

    #!/usr/bin/perl use lib "/path/to/Net::SMTP/module"; use Net::SMTP $host = "SMTP SERVER"; $port = 25; $smtp = Net::SMTP->new($host, Hello => port=>$port) $smtp->mail("FROM EMAIL ADDRESS"); $smtp->recipient("TO EMAIL ADDRESS"); $smtp->data; $smtp->datasend("From: host\"); $smtp->datasend("To: account\\n"); $smtp->datasend("Subject: Test"); $smtp->datasend("\n"); $smtp->datasend ("This is a test"); $smtp->dataend; $smtp->quit;

    When I run this, I get the error:

    "SMTP SERVER" is not exported by the Net::SMTP module. Can't continue +after import errors at line 6.

    What does it mean "is not exported"?

    good morning Perl Monks, I am looking for a more efficient way to write this code. I am copying huge amount of data from Excel spreadsheet with multiple tabs into a Google spreadsheet with multiple tabs but it takes a long time because I am updating it cell by cell, is there a way I can copy the whole worksheet/range of cells and paste it into Google spreadsheet? To make it easier for me, I converted the spreadsheet into cvs files. Any help would be greatly appreciated. Below is the code I am using:

    Nevermind.... I found the batchupdate_cell which is alot faster. Sorry..

Apache::RequestNotes in mod_perl 2.0

    I noticed that Apache::RequestNotes doesn't seem to be available for Apache2 so I am guessing that this functionality was incorporated in mod_perl 2.0 natively?

    If so, would someone kindly point me to an example on how to do this exact same thing with mod_perl 2?

    I need something very early in the request that parses form data and then make it avail to the rest of the request. My current solution involves a PerlTransHandler that slurps the content, parses it and saves it to notes. Then I have to re-inject the raw content back with a PerlInputFilterHandler so it's avail for the rest of the request chain.

    I hate re-inventing the wheel and I think something like Apache::RequestNotes would really be more elegant for what I'm trying to do.

    Many thanks in advance!
