、私は唯一の特定のRatePlanCodeに関連CancelPolicyをしたいです。たとえば、RatePlanCode "49584WPAWAF"のCancelPolicyが必要な場合、このように返す必要があります。この戻りXMLは文字列の形式にする必要があります。

<ns2:CancelPolicy NonRefundable="false"> 
          <ns2:Description>CXL 24HRS PRIOR TO ARRIVAL TO AVOID 1NT PNLTY</ns2:Description> 
          <ns2:CancelPenalties> 
           <ns2:CancelPenalty MaxHoursBeforeCheckIn="24" MinHoursBeforeCheckIn="0" Nights="1" NoShow="false"/> 
           <ns2:CancelPenalty Nights="1" NoShow="true"/> 
          </ns2:CancelPenalties> 
         </ns2:CancelPolicy>

どうすればこの問題に近づくことができますか。私が使うことができる図書館は言及しないでください。そのライブラリを使用してソリューションを提供してください。おかげであなたはRatePlanCode属性値に基づいてRatePlanを見つけるために、次のXPathを使用して、子要素CancelPolicyを返すことができ

：

//ns2:RatePlan[@RatePlanCode='49584WPAWAF']/ns2:CancelPolicy

あなたはxml.etreeを使用してXPathを実行、または次のように* lxmlを使用することができます

from lxml import etree 

raw = '''your xml string here''' 
root = etree.fromstring(raw) 
ns = {'ns2': 'http://www.derbysoft.com/doorway'} 
query = "//ns2:RatePlan[@RatePlanCode='49584WPAWAF']/ns2:CancelPolicy" 
result = root.xpath(query, namespaces=ns) 
print etree.tostring(result[0])

私は名前空間が欲しくない：（xmlns：ns2 = "http://www.derbysoft.com/doorway" xmlns：SOAP-ENV = "http://schemas.xmlsoap.org/soap/封筒/）を私の結果で削除するにはどうすればいいですか？ –
