Here is the "cache.pl" script, that needs to be run each time the site is updated:
#!/usr/local/bin/perl -w
# this script builds a cache of web pages, which can be searched
# by sitesearch.pl; shd be run each time web site content changes
use strict;
use CGI qw(:standard);
use Data::Dumper;
my $dir = 'your_file_path'; # dir to search.
my $ext = 'htm'; # page types to search.
my $cache = 'sitesearch.dat'; # cache file.
my (@Results,$file,$title);
# optional boundaries for search area, to avoid
# searching on repeated text:
my $startstring = 'unique_ident_1';
my $endstring = 'unique_ident_2';
chdir $dir;
# get all the relevant pages, strip out title, file name and
# searchable text, store in array of hashes:
while (<*.$ext>) {
open FILE, $_;
read FILE, $file, -s(FILE);
$file =~ m#<title>(.*?)</title>#i;
$title = $1;
$file =~ s/^.*$startstring/$startstring/s; # delete these 2 lines
+ if
$file =~ s/$endstring.*$//s; # you want to search t
+he whole page
$file =~ s/<[^>]*>/ /g;
push @Results, {filename => $_, title => $title, text => $file};
}
# save the results in the cache file:
open SAVE, ">$cache" or die "could not open $cache $!";
print SAVE Dumper(\@Results);
close SAVE;
# check what has been saved in the cache file, and display it:
open RETRIEVE, $cache or die "could not open $cache $!";
my $data = do { local $/; <RETRIEVE> };
my @Retrieves = @{ my $VAR1; eval $data };
print header,h2('You have successfully cached the following pages:');
print $_->{title},br for @Retrieves;
Here is the "sitesearch.pl" script, which shd be called from a form on all the pages on the site:
#!/usr/local/bin/perl -w
# this script searches the given web directory for
# pages containing the given search term. Need to run
# cache.pl first to create the cache file.
use lib 'your_file_path';
use strict;
use CGI qw(:standard);
use HTML::Template;
my $cache = '/u/www/virtual/w01-0785/sitesearch.dat'; # path to cache
+file.
my $param = 'search'; # name field from input tag
# in calling web page.
# get the web site data from the cache:
open RETRIEVE, $cache or die "could not open $cache $!";
my $data = do { local $/; <RETRIEVE> };
my @Retrieves = @{ my $VAR1; eval $data };
# search the data and pull out the relevant filenames and page titles:
my $SearchTerm = param($param);
my @Results;
my $text;
for (@Retrieves) {
if ($_->{text} =~ /$SearchTerm/i) {
push @Results, {filename => $_->{filename}, title => $_->{title
+}};
}
}
# print the search results:
my $results_tmpl = HTML::Template->new(filename => 'siteresults.tmpl')
+;
$results_tmpl->param(
search_term => $SearchTerm,
results => [@Results],
);
print header;
print $results_tmpl->output();
There also has to be a file called siteresults.tmpl, which shd look like the other html files on the site, but contain, at the appropriate point, this stuff:
# send back the sitesearch input box:
<form method="get" action="http://your_path/cgi-bin/sitesearch.pl">
<input type="text" name="search" size="15" value="<TMPL_VAR SEARCH
+_TERM>">
</form>
.....
# print out the relevant links:
Here are the Pages that match your Search Terms:<br>
<TMPL_LOOP RESULTS>
<a href="http://your_path/<TMPL_VAR FILENAME>"><TMPL_VAR TITLE></a
+><br>
</TMPL_LOOP>

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
