xpath - 信息路径组合框选择项目，除了在其他组合框中选择的项目

Question

我有一个 InfoPath 表单，其中部门作为重复表输入，所有部门都在此处输入。

然后我有第二个重复表，其中输入了用户。该行由 3 列组成：用户名字符串、UserDepartmentCombo1（可从查找部门的下拉列表中选择）和 CoveragePathCombo2 下拉列表（再次从部门列表中查找）。

Infopath 输出的 XML 如下：

<?xml version="1.0" encoding="UTF-8"?>
<?mso-infoPathSolution solutionVersion="1.0.0.6" productVersion="15.0.0" PIVersion="1.0.0.0" href="file:///C:\Users\user\Desktop\test.xsn" name="urn:schemas-microsoft-com:office:infopath:test:-myXSD-2012-10-21T13-16-52" ?>
<?mso-application progid="InfoPath.Document" versionProgid="InfoPath.Document.4"?>

  <my:group1>
    <my:Departments>
      <my:DeptName>Accounts</my:DeptName>
      <my:field3>false</my:field3>
    </my:Departments>
    <my:Departments>
      <my:DeptName>Sales</my:DeptName>
      <my:field3>false</my:field3>
    </my:Departments>
    <my:Departments>
      <my:DeptName>Support</my:DeptName>
      <my:field3>false</my:field3>
    </my:Departments>
    <my:Departments>
      <my:DeptName>Reception</my:DeptName>
      <my:field3>false</my:field3>
    </my:Departments>
  </my:group1>
  <my:group2>
    <my:Users>
      <my:UserDepartment>Sales</my:UserDepartment>
      <my:Username>Chris</my:Username>
      <my:CoveragePath>Reception</my:CoveragePath>
    </my:Users>
    <my:Users>
      <my:UserDepartment>Sales</my:UserDepartment>
      <my:Username>Jon</my:Username>
      <my:CoveragePath>Accounts</my:CoveragePath>
    </my:Users>
  </my:group2>
</my:myFields>

我的CoveragePath组合框 XPath 如下：/my:myFields/my:group1/my:Departments/my:DeptName

我希望组合框CoveragePath下拉列表不包括在行UserDepartment组合框中选择的部门，我将如何执行此操作？

Answer 1

使用：

/my:myFields/my:group1/my:Departments/my:DeptName[not(. = $selected)]

where you need to substitute $selected by whatever was selected in the first combo box.
