java - 如何使用 HAPI 框架工作解析 HL7 多段(ORC/OBR/OBX)？

Question

如何使用 HAPI Framework 解析 HL7 多段(ORC/OBR/OBX)。

我还面临与解析多个实验室订单相关的问题，还面临与特殊字符 (MSH|^~\&#|) 编码相关的问题。

Answer 1

您可以在 get 调用时指定索引，如下所示:

String perOrgCity = terser.get("/.OBX1-24-3");

注意上面代码中OBX1中的1。索引从零开始。如果您想读取多个循环计数器，只需将 1 替换为循环计数器即可。

这里是类似的question .
