目標：讀取兩個字符串，拆分csv並比較xslt中的值1.0

Question

我想弄明白這一點，但已經過了一個星期。任何人都有如何繼續的建議？

我想： splitOne（逗號分隔的任意長度的字符串）的foreach條目，與每個splitTwo（任何長度的逗號分隔的字符串）進行比較。如果匹配，則顯示該節點。如果不是，不要。

如果這是C＃，這將已經結束。但是在XSLT1.0（和僅有的XSLT 1.0）中，這對我來說是個大問題。

splitOne是外環，splitTwo是INNERLOOP。

對於XSLT來說，我可以採用其他方式來執行此操作，但最終產品必須是XML。

這是我運行這個對XML。

我只需要上述其中assocGroup值也是$ Groups_From_Logged_In_User

Answer 1

程序節點我會做一個恆等變換，只有專門處理<Program>元素。我遞歸地分割出第一個CSV並查看它是否出現在assocGroups屬性中。

<?xml version="1.0" encoding="UTF-8"?> 
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
    version="1.0"> 

    <xsl:param name="Groups_From_Logged_In_User"/> 

    <xsl:template match="node()|@*"> 
    <xsl:copy> 
     <xsl:apply-templates select="node()|@*"/> 
    </xsl:copy> 
    </xsl:template> 

    <xsl:template match="Program"> 
    <!-- We have to append a ',' to $Groups_From_Logged_In_User so that we still get 
     something back from substring-before(...,',') in the last iteration --> 
    <xsl:param name="list" select="concat($Groups_From_Logged_In_User,',')"/> 
    <!-- We also add commas around @assocGroups because we want to check for appearances of ",1," 
     rather than "1", as this would also be found in "11", which is not what we want to find --> 
    <xsl:param name="assocGroups" select="concat(',',@assocGroups,',')"/> 
    <xsl:choose> 
     <!-- We we've chipped everything off the list, we quit --> 
     <xsl:when test="$list=''"/> 
     <!-- Now we chip off the first bit of the list, wrap it in commas and see whether it appears in $asscoGroups --> 
     <xsl:when test="contains($assocGroups,concat(',',substring-before($list,','),','))"> 
     <xsl:copy-of select="."/> 
     </xsl:when> 
     <!-- If we didn't find anything, we drop the first value and recurse. --> 
     <xsl:otherwise> 
     <xsl:apply-templates select="."> 
      <xsl:with-param name="list" select="substring-after($list,',')"/> 
      <xsl:with-param name="assocGroups" select="$assocGroups"/> 
     </xsl:apply-templates> 
     </xsl:otherwise> 
    </xsl:choose> 
    </xsl:template> 
</xsl:stylesheet>
