如何EDI標準文件轉換爲自定義XML？

今天分享EDI報文轉換，主要圍繞X12標準 850 採購訂單展開介紹。

以下方案的源代碼先分享出來。
https://www.kasoftware.com/translation/edi_xml_convert_sample.html

實現EDI轉自定義XML，可以分兩步完成。

根據國際標準，先將EDI文件轉換爲標準的XML文件；
通過腳本，實現標準XML與自定義XML的關係映射。

以850採購訂單爲例，源文件如下：

先看轉換標準XML的結果，內容看似很長，一半以上的內容都是註釋，解釋每個字段對應的業務含義，即便沒有EDI規範，也可以快速瞭解該EDI文件都包含了哪些業務數據：

大家可以看下這個XML結構，其標籤名稱與原始EDI文件的Segment名稱都是對應的，從BEG開始，到CTT Segment，不同的segment涵蓋不同的業務數據，根據該XML的Xpath取相關的業務數據，難易程度比直接處理EDI文件低很多。


接下來說說，如何從該XML文件獲取數據，生成一個自定義XML。先看Mapping 源代碼，這段代碼可在Script Port直接運行。

<!-- NOTE: Do not edit -->
<rsb:info title="Custom Script" desc="This script will be executed when a file is processed.">
  <input name="PortId"        desc="The id of this port." />
  <input name="MessageId"     desc="The message id." />
  <input name="FilePath"      desc="The path of the file being processed." />
  <input name="FileName"      desc="The name of the file being processed." />
  <output name="Data"         desc="The data that will be write to Receive folder." />
  <output name="FileName"     desc="The name of the output file in Receive folder." />
</rsb:info>

<rsb:set attr="input.uri" value="[FilePath]"/>
<rsb:set attr="input.xpath" value="/Interchange/FunctionalGroup/TransactionSet/TX-00401-850" />

<rsb:call op="xmlDOMSearch" in="input">
  <rsb:set attr="po.po_no" value="[xpath('BEG/BEG03') | def]" />
  <rsb:set attr="output.data">
   <PURORDER>

   </PURORDER>
 </rsb:set>
</rsb:call>

<rsb:set attr="output.filename" value="PO850#[po.po_no].xml"/>
<rsb:push item="output"/>

代碼實現部分，唯一的亮點就是調用了XMLDomSearch這個ops，掌握了它的調用，又如掌握了全世界:-)
如何正確調用XMLDOMSearch，請看下圖。
