本文介绍了使用 Everest 框架解析 XML 文档(临床文档架构-CDA，HL7 标准)的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在尝试从标准化为 HL7 V3 CDA 标准的 XML 文件中解析一些临床信息.
I am trying to parse some clinical information from XML file that is standardized to HL7 V3 CDA standard .
Xml 文件:

最好的图书馆是什么?我发现 Everest 框架(http://everest.codeplex.com/)非常适合这种工作，但我没有找到任何如何实现这一目标的示例.有没有人以前使用过这个框架?我正在寻找一个例子，我可以将这个 xml 文件反序列化为 ClinicalDocument 类.谢谢
What is the best library to do this?I have found that Everest Framework (http://everest.codeplex.com/) is grate for such kind of work but I did not find any examples how to achieve this.Does anybody used this framework before?I am looking for an example where I can deserialize this xml file into ClinicalDocument class.Thanks
推荐答案
为此，您可以使用以下代码:
To do this you can use the following code:
using(XmlStateReader xr = new XmlStateReader(XmlReader.Create(@"C:\path-to-file.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;
}
不确定这是否会帮助您进行转换，但这会将 CDA 读入 ClinicalDocument 类.
Not sure if that will help you transform, but that will read a CDA into a ClinicalDocument class.
这篇关于使用 Everest 框架解析 XML 文档(临床文档架构-CDA，HL7 标准)的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
