我使用的XSLT是：

所需输出为：

能否请您更正此错误，无法理解我在哪里做错了。

Could you please correct this, unable to understand where i am doing wrong.

谢谢

推荐答案

我发现这些无休止的 concat（）语句不可读。我建议您将它们更改为以下形式的显式指令：

I find these endless concat() statements unreadable. I would suggest you change them to explicit instructions in the form of:

<xsl:variable name="headerText">
    <xsl:value-of select="$header/ns2:MsgId"/>
    <xsl:text>,</xsl:text>
    <!-- ... -->
</xsl:variable>

某些缩进也有助于提高可读性。

Some indentation would also be useful for improving readability.

无论如何，您的错误是在 xsl之外定义了 $ CdtTrfTxInfText 变量： -每条指令。这将使用第一个 CdtTrfTxInf 节点中的值填充变量-然后您只需为每次 CdtTrfTxInf 重复这些值

Anyway, your mistake is defining the $CdtTrfTxInfText variable outside of the xsl:for-each instruction. This populates the variable with values from the first CdtTrfTxInf node - and then you simply repeat these values for each occurrence of CdtTrfTxInf.

尝试摆脱变量，直接从 xsl：for-each 指令：

Try getting rid of the variable and getting the values directly from the current node within the xsl:for-each instruction:

<xsl:for-each select="$pmt/ns2:CdtTrfTxInf">
    <xsl:value-of select="$headerText"/>
    <xsl:text>,</xsl:text>
    <xsl:value-of select="$pmtText"/>
    <xsl:text>,</xsl:text>
    <xsl:value-of select="concat(
    ns2:PmtId/ns2:EndToEndId,',',
    ns2:Amt/ns2:InstdAmt,',',
    ns2:CdtrAgt/ns2:FinInstnId/ns2:BIC,',',
    ns2:Cdtr/ns2:Nm,',',
    ns2:Cdtr/ns2:PstlAdr/ns2:AdrLine[1],',',
    ns2:Cdtr/ns2:PstlAdr/ns2:AdrLine[2],',',
    ns2:Cdtr/ns2:PstlAdr/ns2:Ctry,',',
    ns2:CdtrAcct/ns2:Id/ns2:IBAN,',',
    ns2:RmtInf/ns2:Ustrd)"/>
    <xsl:text>&#xa;</xsl:text>
</xsl:for-each>

这篇关于对于XSLT中的每个循环，仅通过第一条记录的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
