使用Hierarchical Data stage 解析、编写和转换XML数据。 您只能在并行作业中使用 Hierarchical Data stage。 Hierarchical Data stage 可以有多个输入和多个输出链接。 您可以使用 Hierarchical Data stage 作为源阶段,它只有输出链接;中间阶段,它有输入和输出链接;或者目标阶段,它只有输入链接。
If the schema that describes the XML data contains large amounts of information, you can define multiple views of your schema; each view describing one part of your XML schema. You can add one XML composer step for each view to build one part of your XML document. You can assemble all ...

Procedure From the Assembly Editor, click Administration and then select Default Data Type Values. Enter default values. On the XML Parser step, open the Validation window and set the Use global default values for missing values rule to True. Parent topic...
您可以将 XML 或 JSON 文件中的多行作为单个记录传递到 Hierarchical 阶段。 当 XML 或 JSON 文件位于文件存储连接器中时,需要此方法。 当您创建DataStage®流程来解析位于文件存储连接器(例如IBM Cloud® Object Storage、Amazon S3或Google Cloud Storage)到分层数据阶段,您...
使用「階層式資料」暫置來剖析、編製及轉換 XML 資料。 您只能在平行工作中使用「階層式資料」暫置。 「階層式資料」暫置可以有多個輸入及多個輸出鏈結。 您可以使用「階層式資料」暫置作為來源暫置,它只有輸出鏈結; 使用中間暫置,它同時具有輸入及輸出鏈結; 或使用目標暫置,它只有輸入鏈結。
使用DataStage®畫布,將「階層式資料」暫置新增至DataStage流程。 程序 下列範例說明如何將「階層式資料」暫置新增至DataStage流程。 將來源和目標從選用區拖曳至畫布。 開啟選用區的階段區段,並將「階層式資料」階段圖示拖曳至來源與目標之間的畫布上。
IBM InfoSphere DataStage, Version 11.3.1 Example 3: Viewing the output of the jobAfter you run the job, open the .xml file, and look at the output.Procedure From the Assembly Editor, click OK to return to the Hierarchical Data stage editor. Then click OK to close the Hierarchical Data...
In this example, you create a job that uses the Hierarchical Data stage and a Sequential file stage. The OrderJoin step is used to merge the items in the employee and address lists into a single list based on their position. About this task ...
Pass the composed JSON string as a large object. The last stage in the job must be a LOB-aware stage, such as the Db2 connector, Oracle connector, ODBC connector, Teradata connector, or Websphere MQ connector. These stages use the LOB locator string to obtain the JSON data and then wri...
