is the view of the xml fix or is it only your thinkin of storing the data on this way?
use strict;
use XML::Simple;
$filename = "yours.xml";
xml_edit($filename); # return done 1 || error 0
sub xml_edit($){
my$bool=0;
%DB=load($_[0]);
if(exists$DB{student}{id}{2})
{
$DB{student}{gpa}='C';
$bool++;
}
save($_[0],\%DB);
return$bool;
}
#untested
but i recommend you to build a hash of your data within perl and export it via "save($filename,\%hashref);"
for this you got truly the right structure with easy editing potential even if the data gets more bulky.
$perlig =~ s/pec/cep/g if 'errors expected';

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).
