重複網格Orbeon形式：確定相同迭代的字段值

我使用Form Builder（版本4.9）創建包含重複網格的表單。我還定義了一個Process按鈕，以便將表單的數據發送到Servlet（使用send（）方法）。我的目標是將表格數據保存在數據庫表中。重複網格Orbeon形式：確定相同迭代的字段值

我能夠在servlet中接收表單的數據作爲XML，但我注意到在不同的迭代中具有相同值的字段在XML中每個值只出現一次，'for'屬性具有多個值（表示值重複的次數）。但是，我一直無法找到匹配同一迭代的所有字段（表示一個錶行）的方法，所以我無法正確地將數據存儲在數據庫中。

例如，當我下表

HEADERS : FIELD_B  - FIELD_C  - 
ITER_1 : FIELD_B_1 - FIELD_C_1 - 
ITER_2 : FIELD_B_2 - FIELD_C_2 - 
ITER_2 : FIELD_B_3 - FIELD_C_1 -

後，我得到以下XML

<?xml version="1.0" encoding="UTF-8"?> 
<metadata> 
    <control for="e7d2bb4ac261e77159fc236e7fd922c3540756f8" name="section-1" 
     type="section"> 
     <resources lang="en"> 
      <label>Untitled Section</label> 
     </resources> 
    </control> 
    <control for="69ec5abdeb2df55c97bf5b1db46cce6bc841aed8" name="FIELD_A" 
     type="input"> 
     <resources lang="en"> 
      <label>FIELD_A</label> 
      <hint />

     <value>FIELD_A_V</value> 
    </control> 
    <control for="9749b7620379db1e8f86eeceaf52c60fa19484d2" name="FIELD_B" 
     type="input">

      <label>FIELD_B</label> 
      <hint /> 
     </resources> 
     <value>FIELD_B_1</value> 
    </control> 
    <control 
     for="89761405fd9de1a147bdda4d2c9279062b806016 9fa491ba6b72e86919e8a02226e28572c7309311" 
     name="FIELD_C" type="input"> 
     <resources lang="en"> 
      <label>FIELD_C</label> 
      <hint /> 
     </resources> 
     <value>FIELD_C_1</value> 
    </control> 
    <control for="9cf502968950de2af58236fe0aaaab2a4fa5ac6d" name="FIELD_B" 
     type="input"> 
     <resources lang="en"> 
      <label>FIELD_B</label> 
      <hint /> 
     </resources> 
     <value>FIELD_B_2</value> 
    </control> 
    <control for="46337304c26fca5cf9d5e91cdf393e3d39c0fbde" name="FIELD_C" 
     type="input"> 
     <resources lang="en"> 
      <label>FIELD_C</label> 
      <hint /> 
     </resources> 
     <value>FIELD_C_2</value> 
    </control> 
    <control for="1155463007588b06b3842c534ca678aa6f5cf665" name="FIELD_B" 
     type="input"> 
     <resources lang="en"> 
      <label>FIELD_B</label> 
      <hint /> 
     </resources> 
     <value>FIELD_B_3</value> 
    </control> 
</metadata>

正如你所看到的，迭代1和3，FIELD_C包含值FIELD_C_1。解析XML時，我無法找到該字段的值的順序。我結束了不正確的表格：

HEADERS : FIELD_B  - FIELD_C  - 
ITER_1 : FIELD_B_1 - FIELD_C_1 - 
ITER_2 : FIELD_B_2 - FIELD_C_1 - 
ITER_2 : FIELD_B_3 - FIELD_C_2 -

迭代2和3在FIELD_C中有錯誤的值。

如何找到重複字段值的正確順序？

我正在尋找一種解決方案，不需要在表單構建器之外操作表單定義，因爲表單將由最終用戶在不知曉XForms的情況下創建。

中屬性-那個local.xml提交按鈕是：

<property 
    as="xs:string" 
    name="oxf.fr.detail.process.OrbeonFormsPortlet.*.*"> 
    validate-all 
    then send(
     property = "oxf.fr.detail.send.success", 
     uri = "http://localhost:8080/web/guest/testlang/-/oaed-form-requests/pop_up/{xxf:get-request-header('Orbeon-Liferay-User-Id')}", 
     content = "metadata", 
     prune = "false" 
    ) 
</property>

完整形式定義是（形式包含一個字段 - FIELD_A - 外重複網格，其是不相關的問題）：

我確實重現了這一點，這似乎是一個疏忽。控制數據被分組以優化輸出大小，但我現在看到這可能會導致問題！

我不確定是否有可能根據當前結構正確推斷訂單。我添加了一個關於這個的issue。
