我目前正在使用 xslt 将我的 xml 转换为我可以使用的格式的 xml。我有一个新要求，即以 csv 格式的文件提供转换后的输出 xml。

这是 xslt 之前的 xml：

<?xml version='1.0' encoding='UTF-8'?>
<bb:Report_Data xmlns:bb="urn:com.playdate.report/Absence_Balances-Outbound">
   <bb:Report_Entry>
      <bb:projectedBalanceTotal.principalId>1040182074</bb:projectedBalanceTotal.principalId>
      <bb:All_Eligible_Time_Off_Plans_for_Worker>
         <bb:projectedBalanceTotal.planCodeId>Sick</bb:projectedBalanceTotal.planCodeId>
         <bb:projectedBalanceTotal.leaveDescription>Sick</bb:projectedBalanceTotal.leaveDescription>
         <bb:projected_balance_accrual_amount_for_the_pay_period>0</bb:projected_balance_accrual_amount_for_the_pay_period>
      </bb:All_Eligible_Time_Off_Plans_for_Worker>
      <bb:All_Eligible_Time_Off_Plans_for_Worker>
         <bb:projectedBalanceTotal.planCodeId>Vacation</bb:projectedBalanceTotal.planCodeId>
         <bb:projectedBalanceTotal.leaveDescription>Vacation</bb:projectedBalanceTotal.leaveDescription>
         <bb:projected_balance_accrual_amount_for_the_pay_period>3.323077</bb:projected_balance_accrual_amount_for_the_pay_period>
      </bb:All_Eligible_Time_Off_Plans_for_Worker>
      <bb:All_Eligible_Time_Off_Plans_for_Worker>
         <bb:projectedBalanceTotal.planCodeId>Winter Recess</bb:projectedBalanceTotal.planCodeId>
         <bb:projectedBalanceTotal.leaveDescription>Winter Recess</bb:projectedBalanceTotal.leaveDescription>
         <bb:projected_balance_accrual_amount_for_the_pay_period>0</bb:projected_balance_accrual_amount_for_the_pay_period>
      </bb:All_Eligible_Time_Off_Plans_for_Worker>
      <bb:projectedBalanceTotal.effectiveDate1>08122012</bb:projectedBalanceTotal.effectiveDate1>
      <bb:projectedBalanceTotal.effectiveDate2>08262012</bb:projectedBalanceTotal.effectiveDate2>
      <bb:projectedBalanceTotal.effectiveDate3>09092012</bb:projectedBalanceTotal.effectiveDate3>
                <bb:projectedBalanceTotal.employeeId>0260971</bb:projectedBalanceTotal.employeeId>
   </bb:Report_Entry>

</bb:Report_Data>

这是在 @Tim C 的帮助下使用的 XSLT：

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:bb="urn:com.playdate.report/Absence_Balances-Outbound">
   <xsl:output method="xml" indent="yes"/>

   <xsl:template match="/">
      <bb:Report_Data>
         <xsl:apply-templates select="bb:Report_Data/bb:Report_Entry"/>
      </bb:Report_Data>
   </xsl:template>

   <xsl:template match="bb:Report_Entry">
      <xsl:apply-templates select="*[starts-with(local-name(),'projectedBalanceTotal.effectiveDate')]"/>
   </xsl:template>

   <xsl:template match="*[starts-with(local-name(),'projectedBalanceTotal.effectiveDate')]">
      <xsl:apply-templates select="../bb:All_Eligible_Time_Off_Plans_for_Worker">
         <xsl:with-param name="date" select="."/>
      </xsl:apply-templates>
   </xsl:template>

   <xsl:template match="bb:All_Eligible_Time_Off_Plans_for_Worker">
      <xsl:param name="date"/>
      <projectedBalanceTotal>
         <xsl:copy-of select="../bb:projectedBalanceTotal.principalId"/>
         <xsl:copy-of select="*"/>
         <bb:projectedBalanceTotal.effectiveDate>
            <xsl:value-of select="$date"/>
         </bb:projectedBalanceTotal.effectiveDate>
         <xsl:copy-of select="../bb:projectedBalanceTotal.employeeId"/>
      </projectedBalanceTotal>
   </xsl:template>
</xsl:stylesheet>

这是输出：

我有一个紧急要求，需要 csv 格式的每条记录，例如：

projectedBalanceTotal.principalId, projectedBalanceTotal.planCodeId, projectedBalanceTotal.leaveDescription, projected_balance_accrual_amount_for_the_pay_period, projectedBalanceTotal.effectiveDate, projectedBalanceTotal.employeeId
1040182074, Sick, Sick, 0, 08122012, 0260971
1040182074, Vacation, Vacation, 3.323077, 0260971
1040182074, Winter Recess, Winter Recess, 0, 0260971

等等等等

我可以在这个模板上堆叠另一个模板来完成这个吗？

我可以在这个模板上堆叠另一个模板来完成这个吗？

是的。但是“怎么样？” 是一个稍微棘手的问题。

如果您可以使用 XSLT 2.0，只需从现有模板中获取输出，并将其视为另一个输出 CSV 模板的输入文档。

如果您坚持使用 XSLT 1.0，则需要使用 nodeset() 扩展（非标准，但在 XSLT 实现中很常见）。使用此函数将现有模板的输出从结果树片段 (RTF) 转换为节点集，以便新模板可以使用它来将其转换为 CSV。

更新

好的，所以将 XSLT 版本 =“1.0”更改为“2.0”。现在将输出方法从“xml”更改为“text”。

然后修改 match="/" 模板说：

<xsl:template match="/">
   <xsl:variable name="reportData">
      <bb:Report_Data>
         <xsl:apply-templates select="bb:Report_Data/bb:Report_Entry"/>
      </bb:Report_Data>
   </xsl:variable>
   <xsl:text>projectedBalanceTotal.principalId, projectedBalanceTotal.planCodeId, projectedBalanceTotal.leaveDescription, projected_balance_accrual_amount_for_the_pay_period, projectedBalanceTotal.effectiveDate, projectedBalanceTotal.employeeId</xsl:text>
   <xsl:apply-templates select="$reportData//projectedBalanceTotal" mode="xml2csv" />
</xsl:template>

然后添加一个模板将 a<projectedBalanceTotal>转换为 CSV 记录：

<xsl:template match="projectedBalanceTotal" mode="xml2csv">
   <xsl:value-of select="bb:projectedBalanceTotal.principalId" />
   <xsl:text>, </xsl:text>
   ...
   <xsl:text>&#10;</xsl:text> <!-- end of line -->
</xsl:template>
