使用XSLT幫助XML到CSV

Question

我想將xml轉換爲csv。請幫我得到正確的XSL文件

輸出我期待爲（CSV）==>

XSL我能進步是==

<?xml version="1.0"?> 
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
           xmlns:fo="http://www.w3.org/1999/XSL/Format" > 
<xsl:output method="text" omit-xml-declaration="yes" indent="no"/> 
<xsl:template match="/">GAS_DAY,CRT_DT,CRT_TM,TOT_FCAST,CNG_SNCE_LST_NM,NA_RNM_UPDTD 
<xsl:for-each select="//DTL//NRG_FCAST_DTL"> 
    <xsl:value-of select="concat(SHPR_TOT_NRG_FCAST_QRY//GAS_DAY,',',CRT_DT, ',' ,CRT_TM,',' ,TOT_FCAST,',' ,CNG_SNCE_LST_NM,',' ,NA_RNM_UPDTD,' 
    ')"/> 
     <xsl:text>&#xa;</xsl:text> <!-- Add a newline at the end of the record --> 
</xsl:for-each> 
</xsl:template> 
</xsl:stylesheet> 

Answer 1

因爲您的for-each循環正在盯着<NRG_FCAST_DTL>元素，所以需要使用..選擇兄弟元素。這適用於我：

<?xml version="1.0"?> 
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:fo="http://www.w3.org/1999/XSL/Format"> 
    <xsl:output method="text" omit-xml-declaration="yes" indent="no"/> 
    <xsl:template match="/"> 
     <xsl:text>GAS_DAY,CRT_DT,CRT_TM,TOT_FCAST,CNG_SNCE_LST_NM,NA_RNM_UPDTD&#xa;</xsl:text> 
     <xsl:for-each select="//DTL/NRG_FCAST_DTL"> 
      <xsl:value-of select="concat(../../SHPR_TOT_NRG_FCAST_QRY/GAS_DAY,',',CRT_DT, ',' ,CRT_TM,',' ,TOT_FCAST,',' ,CNG_SNCE_LST_NM,',' ,NA_RNM_UPDTD, '&#xa;')"/> 
     </xsl:for-each> 
    </xsl:template> 
</xsl:stylesheet> 

Answer 2

AFAICT，您需要更改：

SHPR_TOT_NRG_FCAST_QRY//GAS_DAY 

到：

../../SHPR_TOT_NRG_FCAST_QRY/GAS_DAY 

不知道你想要做什麼其他的變化。如果您需要重新格式化日期，那麼您需要一個可以爲此調用的命名模板。
