Question

我在使用正确的XML结构输出XML数据（在DB2中）时遇到了一些麻烦。

这是一个带有WHERE子句的查询结果的示例，该子句类似于WHERE InvoiceNumber IN（'383'，'385'）......结果是5行

Inv# InvoiceDate InvoiceAmt  Warehouse  GLAccount PostDate    GLAmount
383  20140526    391         02         020       20170526    72
383  20140526    391         02         030       20170526    252
383  20140526    391         02         040       20170526    67
385  20140527    324         02         020       20170526    72
385  20140527    324         02         030       20170526    252

前三行，因为它们是相同的发票号码（即383），应该产生1个发票标签（如下面的XML所示）。最后两行应该生成另一个发票标记（如下面的XML所示）。

该发票标签包含一个包含所有标题字段的标题标记（即3行之间的常用值，如Inv＃，Invoice Date，Invoice Amount和Warehouse number）。

发票标签还包含详细信息标签，每个标签有3行（即帐户，发布日期和详细金额）。

因此，XML结构应该如下所示......

<Register> 002764
    <Invoice>
              <Header>
                   <InvoiceType>RI</InvoiceType>
                   <Inv#>383</Inv#>
                   <InvoiceDate>20170526</InvoiceDate>
                   <InvoiceAmount>391</InvoiceAmount>
                   <Warehouse>ICE01</Warehouse>
              </Header>
              <Detail>
                   <GLAccount>020</GLAccount>
                   <DetailedAmount>72</DetailedAmount>
                   <PostDate>20170501</PostDate>
              </Detail>
              <Detail>
                   <Account>030</Account>
                   <DetailedAmount>252</DetailedAmount>
                   <PostDate>20170526</PostDate>
              </Detail>
              <Detail>
                   <Account>040</Account>
                   <DetailedAmount>267</DetailedAmount>
                   <PostDate>20170526</PostDate>
              </Detail>
    </Invoice>

    <Invoice>
      <Header>
           <InvoiceType>RI</InvoiceType>
           <InvoiceNumber>385</InvoiceNumber>
           <InvoiceDate>20170527</InvoiceDate>
           <InvoiceAmount>324</InvoiceAmount>
           <Warehouse>02</Warehouse>
      </Header>
      <Detail>
           <GlAccount>020</GlAccount>
           <GlAmount>72</GlAmount>
           <PostingDate>20170526</PostingDate>
      </Detail>
      <Detail>
           <GlAccount>030</GlAccount>
           <GlAmount>252</GlAmount>
           <PostingDate>20170526</PostingDate>
      </Detail>
   </Invoice>
</Register>

我正在尝试将Register标记完全包含所有发票标记，以生成上面显示的确切XML格式。

代码分别输出寄存器标记，而不是寄存器标记包含所有发票。像这样......

    <Register>002764</Register>

    <Invoice>
          <Header>
               <InvoiceType>RI</InvoiceType>
               <Inv#>383</Inv#>
               <InvoiceDate>20170526</InvoiceDate>
               <InvoiceAmount>391</InvoiceAmount>
               <Warehouse>ICE01</Warehouse>
          </Header>
          <Detail>
               <GLAccount>020</GLAccount>
               <DetailedAmount>72</DetailedAmount>
               <PostDate>20170501</PostDate>
          </Detail>
          <Detail>
               <Account>030</Account>
               <DetailedAmount>252</DetailedAmount>
               <PostDate>20170526</PostDate>
          </Detail>
          <Detail>
               <Account>040</Account>
               <DetailedAmount>267</DetailedAmount>
               <PostDate>20170526</PostDate>
          </Detail>
    </Invoice>

    <Invoice>
      <Header>
           <InvoiceType>RI</InvoiceType>
           <InvoiceNumber>385</InvoiceNumber>
           <InvoiceDate>20170527</InvoiceDate>
           <InvoiceAmount>324</InvoiceAmount>
           <Warehouse>02</Warehouse>
      </Header>
      <Detail>

DB2 XML查询未生成预期的XML输出
