Okay, here's the first bit of the Data Dumper result, content edited
for brevity:

$VAR1 = {

'count' => '10',
'story' => {

'16647039' => {
'link' => 'http://www...somelink.html',
'topic' => {
'Health' => {
'short_name' =>
'health'
}
},
'status' => 'upcoming',
'submit_date' => '1256158570',
'container' => {
'Lifestyle' => {

'short_name' => 'lifestyle'
}
},
'comments' => '0',
'description' => [
'Some description
in here'
],
'diggs' => '1',
'media' => 'news',
'href' => 'http://digg.com/
restofurl',
'user' => {
'diggusername' => {
'icon'
=> '',

'registered' => '1255514015',

'profileviews' => '105'
}
},
'shorturl' => [
{
'view_count' =>
'0',
'short_url' =>
'http://digg.com/restofurl'
}
],
'title' => [
'Some title of some
article'
]
},
'22914259' => {
'link' => 'http://www...next-
link.html',
'topic' => {
'World News' => {

'short_name' => 'world_news'
}
},
etc,
etc



Hope that helps, and that somebody is able to assist. Much
appreciated.

Please wrap your lines to 76 characters, and reformat the data so it's
comprehensible when wrapped like that. I don't know what you did to
cause the key indentation to get so confused; whatever it was, please
don't do it again. (DDumper output is not, by default, formatted very
well. I prefer Data::Dump for this reason.)

You need to re-read the section on 'KeyAttr' in XML::Simple. Your
<story>s have been flattened into a hashref, meaning you lose the order
but can look up stories by their 'id' attribute. If you just want to
process the stories in the order they are in the file, you want to
specify KeyAttr => [] (and probably ForceArray => 1 as well), in which
case you will get a structure like

$data = {
count => 10,
story => [
id => '16647039',
link => '...',
...,
],
...,
}

which you can iterate over with

for (@{$data->{story}}) {

Thanks for that Ben, much appreciated. I can play with that now I have
an idea what's going on.

Thanks again!

In addition to what Ben said about KeyAttr, the outermost tag around the
XML is not reported by XML::Simple (unless you specify KeepRoot), so
{stories} does not appear in the data dump, but your original code was
looking for it. (Which caused it to be autovivified)

I don't know if the XML::Simple's default value of KeyAttr is all that
clever. Sometimes trying to making something too simple results in it
being more complicated.
