Answer 1

In your code $feature should contain an array. You can iterate over all this features:
foreach($feature as $f) {
echo $f;
}
Or do you want the features of all items?

Answer 2

Loop through the items and put the Feature attribute in an array?
$feature = array();
foreach($parsed_xml->Items as $item)
{
$feature[] = $item->ItemAttributes->Feature;
}

Answer 3

Looks to me like the feature element is actually an array, you'll just need to iterate through it
// assign the feature array to a var to prevent reading the xml each loop iteration
$features = $parsed_xml->Items->Item->ItemAttributes->Feature
// loop through each feature in the features array
foreach($features as $feature) {
echo "* $feature\n";
}
or if you want to show the index of the feature (which is just 0-n in this case)
// loop through each feature in the features array
foreach($features as $key => $feature) {
echo "$key. $feature\n";
}
