如果我只想返回"www.someTranscript.com "命名空间？我尝试了一些事情。要么我什么都不返回，要么我回来，例如所有< person>，包括来自
名称空间的名称空间。

What if I wanted to return only the data contained within the "www.someTranscript.com" namespace? I've tried a few things. Either I return nothing, or I return e.g. all <person>'s, including those from thewww.someack.com namespace too.

我正在使用LinqtoXML和C＃

I'm using LinqtoXML with C#

推荐答案

XNamespace colTrn =" www.someTranscript.com";

XNamespace colTrn = "www.someTranscript.com";

IEnumerable< XElement> dataElements = doc.Root.Elements（colTrn +" SomeTranscript"）。元素（" TransmissionData"）;

IEnumerable<XElement> dataElements = doc.Root.Elements(colTrn + "SomeTranscript").Elements("TransmissionData");

应该这样做，假设"返回......数据"。表示您想要返回根元素的任何ColTrn：SomeTranscript子元素中包含的传输数据元素。如果您只想处理第一个这样的元素，请使用例如

should do, assuming "returning ... the data" means you want to return the Transmission data element(s) contained in any ColTrn:SomeTranscript child elements of the root element. In case you only want to process the first such elements use e.g.

XElement dataElement = doc.Root.Element（colTrn +" SomeTranscript"）。Element（" TransmissionData"）;

XElement dataElement = doc.Root.Element(colTrn + "SomeTranscript").Element("TransmissionData");

如果这不能解决问题，那么请更详细地解释什么是"数据"。 （你正在寻找哪些节点）。

If that does not solve the problem then please explain in more detail what "data" (i.e. which nodes exactly) you are looking for.
