问题描述
鉴于以下 XML，我可以使用什么查询将 preapprovalKey 的值提取到字符串变量?对 LINQ to XML 来说还是有点新意.
<?xml version="1.0" encoding="UTF-8" ?> - <ns2:PreapprovalResponse xmlns:ns2="http://svcs.paypal.com/types/ap"> - <responseEnvelope> <timestamp>2011-04-05T18:35:32.952-07:00</timestamp> <ack>Success</ack> <correlationId>7cec030fa3eb2</correlationId> <build>1655692</build> </responseEnvelope> <preapprovalKey>PA-9AG427954Y7578617</preapprovalKey> </ns2:PreapprovalResponse>
推荐答案
XDocument doc = XDocument.Load("test.xml");
string preapprovalKey = doc.Descendants("preapprovalKey").Single().Value;
