我正在遍历员工并使用以下循环显示数据：

<xsl:for-each select="Timesheet/TeamMember[EmployeeNumber!='Employee No.']"></xsl:for-each>

在该循环中，我需要执行另一个循环，该循环将显示员工循环当前位置的员工的不同工作订单。以下是我一直在使用的一些代码。问题是它返回整个XML文件的所有不同工单而不是当前员工。我已经反复重复了几个小时，但我要么在XML文件中得到所有工作订单，要么就是0.有人可以给我一些帮助吗？谢谢。

我在XSLT的顶部声明了这个键

<xsl:key name="distinctWorkOrder" match="//WorkOrderNumber" use="."></xsl:key>

这是我一直试图获得员工工作订单的循环

<xsl:for-each select="..//WorkOrderNumber[generate-id() = generate-id(key('distinctWorkOrder', .)[1])][//EmployeeNumber=$empId])">

更新： 输出是HTML。为了显示员工信息，我这样做了：

<tr style="height:20px;">
                        <td class="normalBorders" style="text-align:left;">Name</td>
                        <td class="borderT" style="text-align:center;">
                            <div style="border-bottom:1px solid black;height:12px;width:200px;">
                                <xsl:value-of select="EmployeeName"></xsl:value-of>
                            </div>
                        </td>
                        <td colspan="2" class="borderT" style="text-align:right;">Emp. ID#</td>
                        <td colspan="2" class="borderT" style="text-align:center">
                            <div style="border-bottom:1px solid black;height:15px; width:100%;display:inline-block;">
                                <xsl:value-of select="EmployeeNumber"/>
                            </div>
                        </td>
                        <td colspan="2" class="borderT">&#160;</td>
                        <td rowspan="2" colspan="4" class="borderT borderR">
                            <div style="width:100%;height:27px;border-bottom:1px solid black;">
                                <img src="{../Signatures/Path}" style="width:100%;height:34px;"/>
                            </div>
                        </td>
                    </tr>
                    <tr style="height:20px;">
                        <td class="borderL" style="text-align:left;">Sign/Date</td>
                        <td style="text-align:center;">
                            <div style="border-bottom:1px solid black;height:12px;width:200px;">
                                <xsl:value-of select="EmployeeName"></xsl:value-of>
                            </div>
                        </td>
                        <td colspan="5">&#160;</td>
                        <td style="text-align:right;">Approved</td>
                    </tr>

这里我需要循环并输出与此

类似的工单数据 
<xsl:for-each select="..//WorkOrderNumber[generate-id() = generate-id(key('distinctWorkOrder', .)[1])][//EmployeeNumber=$empId])">
<tr>
                 <td class="normalBorders"><xsl:value-of select="//WorkOrderNumber"/></td>
               <td>Other data</td>
    </tr>

以下是如何操作（HTML格式留作读者练习）：

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output omit-xml-declaration="yes" indent="yes"/>
 <xsl:strip-space elements="*"/>

 <xsl:key name="kEmpOrder"
  match="TeamMember[not(EmployeeNumber='Employee No.')]/*/*/WorkOrderNumber"
  use="concat(../../../EmployeeNumber, '+', .)"/>

 <xsl:template match="TeamMember">
  <Employee>
     <xsl:copy-of select="*[starts-with(name(), 'Employee')]"/>
     <WorkOrders>
      <xsl:copy-of select=
      "*/*/WorkOrderNumber
           [generate-id()
           =
            generate-id(key('kEmpOrder',
                             concat(../../../EmployeeNumber, '+', .)
                             )[1]
                      )
         ]
      "/>
     </WorkOrders>
    </Employee>
 </xsl:template>
 <xsl:template match="text()"/>
</xsl:stylesheet>
