如何使用 HAPI 框架工作解析 HL7 多段（ORC/OBR/OBX）？
How to parse HL7 multiple segments(ORC/OBR/OBX) using HAPI Frame work?
如何使用 HAPI 框架解析 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。

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。
这是类似的question。

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。
这是类似的question。
