I have a serialized XML document in an associative array using
XML_Serializer. Due to the use of namespaces, many of the elements in
the document use a colon ( within the name. Since the names are
stored as the array key, this causes problems with smarty.

How do I reference a variable such as this within smarty:
$array['xlink:href'] ?

When I attempt to use the correct syntax {$array.xlink:href} I get the
following error:
syntax error: unrecognized tag

Any ideas?

Thanks
Andrew
