You could patch the ticker to return the data in its flat record, parent pointer form instead of as a recursive data structure. Building the tree from the flat structure is a lot easier than reading the nested XML.
And now ive patched the ticker to do just this. And return some additional information. Try using 'flattree=1' to get the new output. Also, the ticker now responds to xmlstyle settings and has the customary info tag with data about the ticker and stuff like that.
You can build a fully connected tree structure from the "flattree" output quite easily. The algorithm is as follows:
my $res = $o->pm_get( node_id => 180684, id => 505536, flattree => 1 )
+;
my $data = XMLin( $res->content, ForceArray => 0 );
my %nodes;
foreach my $node ( @{ $data->{node} } ) {
my $nid = $node->{node_id};
# register this node so children can find it
$nodes{ $nid } = $node;
if ( my $pid = $node->{parent_node} ) {
# tell the parent about this child
$nodes{$pid}{kids}{$nid} = $node;
# make the reference to the parent "hard" and not "soft"
$node->{parent} = $nodes{$pid};
}
}
You are guaranteed that this will work. You dont need to worry about the parent not existing, or anything like that.

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).
