Subject: Need help pruning data..
Hi all,
I've got an array that contains several dozen IP addresses
(along with a bunch of garbage output from running the NMAP command). I
want to find the fastest, cleanest way to remove all IP address who's
last octet is 10 or below and all IP addresses who's last octet is 200
or higher. I can think of several ways to do this by using reg ex's and
looping through the data but am wondering if there is a faster way, or,
if not, if a cleaner way than what I've come up with:
my $bad_ip;
my @results = `c:/perl/nmap/nmap.exe -sP -n $Subnet`; #subnet is a /24
private IP block
foreach (@results) {
if (/(\d+\.\d+\.\d+\.(\d+))/ { #match on IP addresses only
if ($2 =~ reg ex to match numbers 10 or below or
regex to match numbers 200 orgreater) {
next;
}
else {
..do something..
}
}
}
Thanks,
Matt

Thanks for the suggestions. I've always said that the first priority should be readbility; after all that's what programming languages are for! If you find something's running too slowly then tune it up, but otherwise leave it as it is. The benchmarks differ by a factor of only just over two, and surprisingly that's about the limit of our perception of performance! That's why overclocking isn't worth it and you should only upgrade PC components if you can provide a speed or capacity increase of at least double :) Rob ___ Perl-Win32-Users mailing list [EMAIL PROTECTED] To unsubscribe: http://listserv.ActiveState.com/mailman/mysubs

Title: RE: Can a variable be made like this?
you can do what you want, but not quite as you stated. It would be something like this:
$hi = $db-lookup; # how you do this depends on your db and script
$hello = ${hi}goodday;
print $hello;

RE: Yet another regex question
I'm trying to grab a website's description from the meta tags
but I can't seem to make it work all the time.
As people have pointed out, it's best to use a parser to parse HTML, not a
regex. Here's some code (untested) as a starting point for two different
parsers.
# Sample HTML::Tokeparser code:
$p = HTML::TokeParser-new($filename);
my $desc = ;
while (my $token = $p-get_tag(meta)) {
if ($token-[1]{name} eq description) {
$desc = $token-[1]{content};
}
}
# Sample XML::LibXML code (handy if you plan to do
# more sophisticated parsing or XML parsing too)
my $p = XML::LibXML-new()-recover(1);
my $doc = $p-parse_html_file($filename);
my $desc =
$doc-findvalue('/html/head/meta/@content[../@name=description]');

Search Engine for intranet web site
Hello there, I am trying to setup a search engine for the web-site I have created. I have setup a search engine script using the File::Find module but it is really slow. Anyone know of any faster way of doing so - maybe a grep of all the files within a directory and its sub-directories for the title only to make it faster. I would like to give the user an option of searching just the title or brief description or entire contents of the file.

Adding pod to the ActiveState HTML documentation
Hello, I am wondering if someone knows how to add POD documentation for a module that was installed from CPAN (and not PPM) to ActiveState Perl's HTML documentation system. I have looked through the ActiveState docs, and have not found it mentioned... I see two things that need to be done if I want to do this manually : - use pod2html to convert the POD to HTML. * I need the right CSS to make it look like ActiveState's HTML docs * I need the right command line parameters to pod2html so that the docs will link properly to other modules' documentation - add the link for the newly generated HTML file to the perltoc.html file, so that it will show up in the right-hand frame So if someone has the right command line parameters to pod2html to make it look right and link correctly, I could do the rest manually. On the other hand, if someone knows how PPM does it, so that I have an automatic way of doing it all the right way (TM), I would be happier with that... I have looked through the PPM source code, including its various modules, and haven't found anything that looked like a system(pod2html ...); call.

RE: Search Engine for intranet web site
Well, my search script currently parses
the main directory and all its sub-directories for html files and then uses
regular _expression_ to match the words user has entered for the search
open(IFP, $File::Find::name) or print Search error $! :$fname br;
# only if html file
my $string = IFP;
close(OFP);
return unless ($string =~ /\Q$keywords\E/i);
if ($string =~ /title(.*?)\/title/is)
{
$page_title = $1;
}
I have a feeling that this is not the most
efficient way of searching for all files that contain the words the user
entered in his search criteria. And it is also very slow.
So I am looking for some code examples or
modules I can use for the search engine so that it will be a faster.
Thanks

RE: Adding pod to the ActiveState HTML documentation
Hi Jean-Sébastien, Fortunately, you don't need to do this manually. Copy your POD file in the Perl directory somewhere near other POD files like Perl\lib\... or Perl\site\lib\... Open a command prompt then executes this command perl -MActivePerl::DocTools -e UpdateHTML() The Html file of your POD will be generated automatically and it will be integrated into the Core Perl HTML Documentation of ActiveState. (You will see it when browsing the right-hand frame.)
