现在，我找到了 Everest 框架来解析它（但我不知道这个框架是否是这样做的好框架）。所以我有这段代码来解析文件：
using (XmlStateReader xr = new XmlStateReader(XmlReader.Create(@"C:\Users\michele.castriotta\Desktop\document.xml")))
{
var fmtr = new XmlIts1Formatter();
fmtr.ValidateConformance = false;
fmtr.GraphAides.Add(new ClinicalDocumentDatatypeFormatter());
var parseResult = fmtr.Parse(xr, typeof(ClinicalDocument));
// There is a variable called structure which will contain your
var cda = parseResult.Structure as ClinicalDocument;
}
此代码有效，但我不知道如何从 ClinicalDocument Onject 中找到例如问题部分或另一个部分
