jquery - jqueryでxmlノードの子を解析する

Question

次の XML があります。

<item p4:stage="Ways and Means resolution" xmlns:p4="urn:services.parliament.uk-bills.ext"><guid isPermaLink="true">http://services.parliament.uk/bills/2013-14/antisocialbehaviourcrimeandpolicingbill.html</guid><link>http://services.parliament.uk/bills/2013-14/antisocialbehaviourcrimeandpolicingbill.html</link><category>Commons</category><category>Government Bill</category><title>Anti-social Behaviour, Crime and Policing</title><description>To make provision about anti-social behaviour, crime and disorder, including provision about recovery of possession of dwelling houses; to make provision amending the Dangerous Dogs Act 1991, Schedules 7 and 8 to the Terrorism Act 2000 and the Extradition Act 2003; to make provision about firearms and about forced marriage; to make provision about the police, the IndependentPolice Complaints Commission and the Serious Fraud Office; to make provision about criminal justice and court fees; and for connected purposes.</description><a10:updated>2013-06-05T17:42:59+01:00</a10:updated></item>

<item></item>これを使用して、すべてのことを解析できます。

$(xml).find('item').each(function() {
    var stage = $(this).find('title').text();
    console.log(stage);
});

しかし、私は中身を見ています：

<item....>  for example, 

内部にあるものを引き出す必要があります：

 <p4:stage></p4:stage>

これを引き出すにはどうすればよいですか？

前もって感謝します
