从XML获取价值

Question

我有一个XML。如何从中获取CustomerSet值？

<a:CreditCards>
 <a:CreditCard>
  <a:AccountNumber>1234XXXXXX23XXXX</a:AccountNumber> 
 <a:ExtendedInfo>
  <a:CustomerSet>RC808687</a:CustomerSet> 
 </a:ExtendedInfo>
 </a:CreditCard>
<a:CreditCards>

Answer 1

尝试使用XPath， 要获取CustomerSet值，xpath将为/CreditCards/CreditCard/ExtendedInfo/CustomerSet

Answer 2

看看这个

XmlDocument xml = new XmlDocument();
            xml.LoadXml("<CreditCards>  <CreditCard>   <AccountNumber>1234XXXXXX23XXXX</AccountNumber>   <ExtendedInfo>   <CustomerSet>RC808687</CustomerSet>   </ExtendedInfo>  </CreditCard> </CreditCards> ");
            XmlNodeList xmlList = xml.SelectNodes("/CreditCards/CreditCard/ExtendedInfo/CustomerSet");
