Hi, you should dump $doc with something like Data::Dumper:
$VAR1 = {
'document' => {
'\\2006\\200601\\20060125\\20060125_19.txt' => {
'record' => [
{
'group' => 'P6',
'data-class' => 'Target',
'sentence-number' => '3'
},
{
'group' => 'P6',
'data-class' => 'Good',
'sentence-number' => '12'
}
],
'sourcecategory' => 'News Archive',
'datetime' => '2006/01/25',
'schemeversion' => '1.1'
},
'\\2006\\200601\\20060125\\20060125_18.txt' => {
'sourcecategory' => 'News Archive',
'datetime' => '2006/01/25',
'schemeversion' => '1.1'
}
}
};
As you can see, the records are an array ref of hashrefs at the same level as the documents attributes ($doc->{document}->{$key}->{record}). You can iterate over the records at this point (i.e. check if record is defined and is an arrayref).

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).

or How to display code and escape characters
are good places to start.
