推荐答案

你在使用XmlDocument.SelectNodes吗？



如果是这样，我怀疑你遇到了第三行命名空间的问题 - 适用于GetPatientFullMedicationHistoryResponse元素中的所有元素。



为了使用XPath选择所需的元素，您需要使用XmlNamespaceManager指定要使用的前缀。 （这是违反直觉的。）

我没有用来做那个方便的代码，我还没有去写一篇文章。





如果我没记错的话，你需要使用;

Are you using XmlDocument.SelectNodes ?

If so, I suspect that you are running into a problem with the namespace on the third line -- which applies to all the elements within the GetPatientFullMedicationHistoryResponse element.

In order to use XPath to select the desired Element you need to specify a prefix to use by using an XmlNamespaceManager. (It's counter-intuitive.)

I don't have the code I use to do that handy and I still haven't gotten around to writing an article on it.


If I recall correctly, you'll need to use;

System.Xml.XmlNamespaceManager nsm = new System.Xml.XmlNamespaceManager ( Document.NameTable ) ;
nsm.AddNamespace ( someprefix , "https://secure.newcropaccounts.com/V7/webservices" ) ;

然后使用someprefix作为前缀。

Then use someprefix as the prefix.
