Question

我有835个EDI文件，

ISA*00*          *00*          *33*83876          *ZZ*B00482000   *190128*1100*^*00501*000000001*0*T*:~
ST*835*000000001~
BPR*H*0*C*NON************20190128~
TRN*1*PK673981180*141138499245*PS0087726~
REF*EV*B048499999800~
REF*F2*1083~
DTM*405*20190128~

我应该如何提取ST值，即000000001，等等，

我尝试先使用SMOOKS将edi文件转换为XML格式，然后再通过父级和子级节点检索数据。

  public static void main(String[] args) throws SmooksException, Exception {
    String modelURI = "urn:org.milyn.edi.unedifact:d99a-mapping:1.4";
    UNEdifactInterchangeParser parser = new UNEdifactInterchangeParser();
 //   parser.addMappingModels(modelURI, new URI("/"));
    parser.setFeature(EDIParser.FEATURE_IGNORE_NEWLINES, true);
    SAXHandler handler = new SAXHandler();
    parser.setContentHandler(handler);
    parser.parse(new InputSource(new java.io.FileInputStream(
            "myEDIfile.edi")));
    Document doc = handler.getDocument();
    // Here you have your document
    new XMLOutputter(Format.getPrettyFormat()).output(doc, System.out);
}
