xpath_register_ns problem

I was testing out this function today (xpath_register_ns) and I found a possible problem in its implementation. If you use several namespaces in you document and then define a last one to be the default namespace, how are you supposed to register this with the php function. Example: <?xml version="1.0" encoding="utf-8"?> <rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#" xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:pl="http://mojavelinux.com/rss/1.0/modules/places" xmlns="http://purl.org/rss/1.0/" > <channel rdf:about="http://mojave.mojavelinux.com/newsletter/"> <title>Local Sights and Attractions in Washington/Balimore for the Dan &amp; Sarah Wedding</title> <link>http://mojave.mojavelinux.com/newsletter/</link> <description>Places in the Washington/Baltimore area where our guest may entertain themselves.</description> (clip...) Now if you run the query $ctx->xpath_register_ns('rdf', 'http://www.w3.org/1999/02/22-rdf-syntax-ns#'); $ctx->xpath_register_ns('dc', 'http://purl.org/dc/elements/1.1/'); $ctx->xpath_register_ns('pl', 'http://mojavelinux.com/rss/1.0/modules/places'); $ctx->xpath_register_ns('', 'http://purl.org/rss/1.0/'); $ctx->xpath_eval('//channel'); You get no results. However, if you replace the last namespace declaration with the name of 'rss' and change call the tags to <rss:*> and then do the query $ctx->xpath_eval('//rss:channel'); You get the expected results. So basically, it seems that the xpath_register_ns function does not allow you to register a default namespace.
