Another method to use for modules you don't have in @INC is:
# yoursript.pl
use FindBin;
use lib $FindBin::Bin; # adds location of script to @INC
use yourmodule;
This method requires yourmodule.pm be in the same directory as
yourscript.pl

Ok after some research I think I can better narrow down the problem I'm
having. The module XML::Filter::SAX1toSAX2 is converting my html
entities ( ’ etc...) to weird characters.
I changed the XML::SAX::Machines Pipeline in my code from this:
my $machine = Pipeline(
'XML::Filter::SAX1toSAX2' =>
'XML::Filter::BufferText' =>
'XML::Filter::HtmlTagStripper' =>
$writer
);
to
my $machine = Pipeline(
'XML::Filter::SAX1toSAX2' =>
\*STDOUT
);
and it's converting the entities to gibberish. Is there another
SAX1toSAX2 like module out there? Can anyone thing of a replacement?
If i remove the SAX1toSAX2 call from the Pipeline, there's no output.
Also, on a side note I previous decoded the input using
MIME::Decoder...
Any help would be greatly appreciated.

Hi afrinspray, Im Todd W, the author of node 554219.
I glossed over (i.e. ignored) some things you have to keep in mind when
using XML processors.

Well once you know whats going on you cant really call the output jibberish,
as it is by design. Basically you are having an encoding issue. The
following rambling is my attempt to explain well enough for you to come up
with a solution.
Theres a few things going on here, so I need to break this up.
First, to explain how it is possible that you do not see ’ in your
output even though it is in your input.
Lets take a look at a more familiar feature of XML.
The XML illustrated here:
<tag attribute="value" />
is, to an xml parser, identical to the following snippet:
<tag attribute="value"></tag>
Also, this piece of XML:
<tag attribute="value">text</tag>
Is identical to this one:
<tag attribute='value'>text</tag>
To repeat: An xml parser (like your browser, or libxml2), dosent store
information about the document at that level. It dosent care if attribute
values are surrounded with single quotes or double quotes, or the tag ends
with a / then a >, or with a closing </tag>. SGML says the parser must
interpret the markup identically.
The situation is the same with your issue, character entity references. A
parser must expand the entity reference, and is not allowed to differentiate
between an entity reference (i.e. &XXXX;) and the entity itself.
Thats why it is even possible in the first place for the entity reference to
not appear in the output document even though it is in the input document.
So to answer your question, "Can I pass the entity reference through
unexpanded?", the answer is no. Of course you could do something like dig in
the code and find the part that expands entity references and have it change
the reference to text, but youd be hacking the parser, making it do
something its not supposed to do.
The next issue, the reason it appears as "jibberish" and not the expanded
entity, is:
1: you are not exporting the data from perl as UTF8
and/or
2: your document reader is either not configured to or capable of rendering
UTF8.
Now, as to what to do from here. Thats even harder to explain than the (far
from thorough) explination I gave above. I'll proceed by grabbing the code
and data from that node, making some modifications, and describing my
observations. The first thing I do is grab the data file from the node and
change it to:
<html>
<head>
<title>Test Document</title>
</head>
<body>
<p>The first paragraph</p>
<p>the second paragraph</p>
<hr width="75%">
<div>last ’ modified: WHENEVER</div>
</body>
</html>
I run the program on it, and indeed I get jibberish:
C:\download\misc>strip.pl striptags.html
Wide character in print at C:\download\misc\strip.pl line 28.
Test Document<p>The first ?á paragraph</p><p>the second
paragraph</p><div>last ?ÇÖ modified: WHENEVER</div>
Along with the "jibberish" I see a warning, "Wide character in print". This
tells me I need to change the output layer encoding to UTF8 (because I know
the data is stored in perl as UTF8).
So right before the
print $output;
in the program I add
binmode STDOUT, ":utf8";
C:\download\misc>strip.pl striptags.html
Test Document<p>The first ?á paragraph</p><p>the second
paragraph</p><div>last ?ÇÖ modified: WHENEVER</div>
No more warning, but still "jibberish". Makes sense actually: my console
dosent know how to render UTF8. But, IE has UTF8 aware parser. So I run:
C:\download\misc>strip.pl striptags.html > striptags.out.html
C:\download\misc>iexplore striptags.out.html
Okay, it displays properly in the browser. I can see the non breaking space,
and I can see the right single quote. I'm suprised, acutually. I would have
thought I needed to add a:
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
Can Firefox do it right automatically? Nope:
C:\download\misc>"c:\program files\mozilla firefox\firefox.exe"
striptags.out.html
shows the "jibberish". But, if I add the meta tag above to the beginning of
the file it renders properly.
Thanks for posting it was nice to get this written down.

split() in scalar context is deprecated because of its side effects.

Code that gives the wrong answer is not very useful...
----------------------------
#!/usr/bin/perl
use warnings;
use strict;
my $s = "this string has this in it this many times: 3\n";
my $count = split(/this/, $s);
print "$count\n";
$s = "a telepathist would say there is one in this string\n";
$count = split(/this/, $s);
print "$count\n";

You have to convert some file to an Excel spread sheet?
Open the file, parse what you want out of it, then write it using
Spreadsheet::WriteExcel.
http://search.cpan.org/~jmcnamara/Spreadsheet-WriteExcel-2.17/lib/Spreadsheet/WriteExcel.pm

There are a lot of modules on CPAN to mail attachments. Give it a try:
http://search.cpan.org
> and all this should be done in perl....
Hence the post to comp.lang.perl.misc. Why not write it in a language
you know?

No thanks, I'll just post a response when I feel like it. :-)

What the file's extension is is irrelevant. What matters is the format
of the data inside the file. .dat is commonly used for many different
file formats. If you can tell us what the format is, we may be able to
help you read it in Perl.

When you want to do something complicated in Perl, first try looking at
http://search.cpan.org . Searching for 'excel' gives, on the first page
of results, the modules Spreadsheet::WriteExcel, for creating Excel
spreadsheets on any machine.

I would use the MIME::Lite module for this, though there are other
options.

Additions like this are considered rude here, as is writing without
capital letters or punctuation.

Start with the documentation for Net::Telnet
perldoc Net::Telnet
From the documentation:
login - perform standard login
This method performs a standard login by waiting for a login prompt
[...]If any of those prompts sent by the remote
side don't match what's expected, this method will time-out, unless
timeout is turned off.
[...]
Use "dump_log()" to debug when this method keeps timing-out and you
don't think it should.
Maybe waitfor() will help.

yes, I have some ideas. gather round kids while I read some
documentation!
It was a dark and stormy night and Net::Telnet said:
[The login()] method performs a standard login by waiting for a
login prompt and responding with *$username*, then waiting for
the password prompt and responding with *$password*, and then
waiting for the command interpreter prompt. If any of those
prompts sent by the remote side don't match what's expected,
this method will time-out, unless timeout is turned off.
Login prompt must match either of these case insensitive
patterns:
/login[: ]*$/i
/username[: ]*$/i
Password prompt must match this case insensitive pattern:
/password[: ]*$/i
Yes, Perl tries to DWIM, but come on...
I suggest you RTFM before asking the follow-up question "ok, so how
do I send my password to _my_ box?"

I deal with 3 clusters all day long, which at all times, 2 clusters are

green for two clusters and a red for the one that is out. But I would
like to put this in a timetable graph so that they can see which
clusters were in at a certain time. Can somebody give some 'keywords'
