在Mirth中如何解析xml字符串

Question

我有一個從DB輸出的列作為xml字符串。 我想解析這個xml對象，我可以通過使用轉換為xml字符串

var xmlResponse=new XML(msg['xmlcontent'].toString());

在下一行中，如果有任何替代方法，我想遍歷每個節點如何執行此操作，請在下面建議使用mirth的xml字符串。

<?xml version="1.0" encoding="utf-8" ?><ORDERMESSAGE><MSH><Sending_Application>HIS</Sending_Application><Sending_Facility>555</Sending_Facility><Receiving_Application>LIS</Receiving_Application><Receiving_Facility/><Message_Date_Time>20160803122348</Message_Date_Time><Security/><Message_Type>ORM</Message_Type><Message_Control_Id/></MSH><ENV><Event_Type_Code>O01</Event_Type_Code><Recorded_DateTime>20160803122348</Recorded_DateTime></ENV><PID><Patient_Id_Ext/><Patient_Id_Int>448</Patient_Id_Int><Patient_Id_Type/><Patient_Id_Number/><Patient_Name>Test Health Check</Patient_Name><Date_Of_Birth>19810802</Date_Of_Birth><Gender_Code>F</Gender_Code><Race_code/><Address1>GUINDY</Address1><Address2/><Address3/><City>Bid</City><State>Maharashtra</State><Postal_Code/><Country_Code>India</Country_Code><Phone_Home/><Phone_Mobile>9764646545</Phone_Mobile><Phone_Business/><Primary_Language/><Marital_Status_Code>Married</Marital_Status_Code><Nationality_Code>Indian</Nationality_Code></PID><PV1><SetIDPatientVisit>574</SetIDPatientVisit><Patient_Type_Code>O</Patient_Type_Code><Ward_Code/><Admission_Type/><Preadmit_Number/><Specialty_Code/><Referring_Doctor_Code/><Referring_Doctor_Desc/><Consulting_Doctor_Code/><Consulting_Doctor_Desc/><Admitting_Doctor_Code/><Admitting_Doctor_Desc/><Patient_Class/><Visit_Number>1146</Visit_Number><Financial_Class_Code/><Admit_DateTime>20160803122003</Admit_DateTime></PV1><ORC><Order_Control>NW</Order_Control><ORC_Placer_Order_Number>544</ORC_Placer_Order_Number><ORC_Filler_Order_Number/><Placer_Group_Number/><Order_Status_Code>Paid</Order_Status_Code><Response_Flag/><ORC_Quantity_Timing>20160803122032</ORC_Quantity_Timing><Parent/><DateTime_Of_Transaction>20160803122032</DateTime_Of_Transaction><Entered_By_ID>9188</Entered_By_ID><Entered_By_Name>Kutti</Entered_By_Name><Verified_By_ID/><Verified_By_Name/><ORC_Ordering_Provider_ID>1</ORC_Ordering_Provider_ID><ORC_Ordering_Provider_Name/><Enter_Location/><Call_Back_Phone_Number/><Order_Effective_DateTime/><Order_Control_Code_Reason/><Entering_Organization/><Entering_Device/><Action_By/><Advanced_Beneficiary_Notice_Code/><Ordering_Facility_Code/><Ordering_Facility_Name/></ORC><OBR><Set_Id_OBR>1</Set_Id_OBR><OBR_Placer_Order_Number>309</OBR_Placer_Order_Number><OBR_Filler_Order_Number/><Package_Code/><Package_Description/><Test_Code/><Test_Name>ABSOLUTE BLAST COUNT</Test_Name><Priority_Code/><Priority_Desc/><Requested_DateTime>20160803122032</Requested_DateTime><Observation_DateTime/><Observation_End_DateTime/><Collection_Volume/><Collector_Identifier/><Specimen_Action_Code/><Danger_Code/><Relevant_Clinical_Info/><Specimen_Received_DateTime/><Specimen_Source_Code/><Specimen_Source_Desc/><OBR_Ordering_Provider_ID>1</OBR_Ordering_Provider_ID><OBR_Ordering_Provider_Name/><Order_Callback_Phone_Number/><Placer_Field1/><Placer_Field2/><Filler_Field1/><Filler_Field2/><Status_Change_DateTime/><Charge_To_Practice/><Diagnostic_Serv_Sect_Code/><Diagnostic_Serv_Sect_Desc/><Result_Status/><Parent_Result/><OBR_Quantity_Timing/><Unit_Code/><Unit_Desc/><Result_Copies_To/><Transportation_Mode/><Reason_For_Study/><Principal_Result_Interpreter/><Assistant_Result_Interpreter/><Technician/><Transcriptionist/><Scheduled_DateTime/><Number_Of_Sample_Containers/><Transport_Logistics_Of_Collected_Sample/><Collector_Comment/><Transport_Arrangement_Responsibility/><Transport_Arranged/><Escort_Required/><Planned_Patient_Transport_Comment/><Procedure_Code/><Procedure_Code_Modifier/><Placer_Supplemental_Service/><Filler_Supplemental_Service/><Cancel_Reason_Code/><Cancel_Reason_Desc/><FeeId>23</FeeId><FeeType>INV</FeeType><MappingId>0</MappingId></OBR></ORDERMESSAGE>

Answer 1

Mirth Connect使用Rhino作為JavaScript引擎。 反過來，JavaScript將E4X或ECMAScript用於XML，以簡化編寫用於處理XML的代碼的任務。

因此，基本上，您的問題分為兩個部分：

1）要訪問或分配數據Feed中的各個字段，您可以使用點符號，如下所示：

var eventType = xmlResponse['ENV']['Event_Type_Code'].toString();

2）遍歷所有或重復的節點，方法是選擇“消息功能”類別（在任何轉換器編輯器的右上角），以檢查Mirth參考功能，在這里您將看到“遍歷段”或“遍歷所有段”的代碼片段，然后拖動並修改它，如下所示：

for each (seg in xmlResponse.OBR.children()) {
    if (seg.name().toString() == "SEG") {
        var sample_value = seg['SEG.1']['SEG.1.1'].toString();
    }
}

但就您的特殊情況而言，據我所知，您沒有重復的句段，因此最好選擇第一種方法。
