是否有可能在此XSLT上构建转换为CSV格式的文件？

我目前正在使用xslt将xml转换为我可以使用的格式的xml。我有一个新的要求，即在csv格式的文件中提供转换后的输出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：

<?xml version="1.0"?>

我有一个紧急需求，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

我可以在这一个上面堆叠另一个模板来实现这一目标吗？

我可以在这个上面堆叠另一个模板来完成   此？

是。但“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。

如果您遇到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，以便新模板将其用于将其转换为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>

然后添加模板以将<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>
