Greetings Monks:
I'm having a problem trying to pattern match. What I'm trying to do, is look through a file containing records, each record contains multiple XML tags. I want to find the record containing a tag that has data of a specific length (in this case, 58 characters).
My basic code is:
# The filename should be the first arguement
$file = $ARGV[0];
# The search string should be the second arguement
$searchString = $ARGV[1];
$matchesFound = 0;
if (-e $file) {
open (INPUTFILE, "<$file") or die "Can't open $file for input.\n";
while ($record = <INPUTFILE>) {
$_ = $record;
if (/$searchString/g) {
print $record;
$matchesFound = $matchesFound + 1;
}
}
close INPUTFILE;
print "$matchesFound found.\n";
}
else {
print "$file doesn't exist.\n";
}
The problem is, that I'm not quite sure exactly what expression I should be feeding to the script. Is there a way to find, say, 58 matches of a alphanumberic or space?
Thanks in advance for your help.

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).
