      </Product_To_Product>
   </Package>
</Root>

在这里，如果带有任何产品的Association_End_Date过时，我想删除整个Product_To_Product元素。为此，我写了下面的代码，我通过C＃函数比较日期，但我仍然无法删除实体。请告诉我哪里出错了。 XSLT代码：

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

<msxsl:script language="C#" implements-prefix="cs">
 <![CDATA[public static long compareDate(long Asso_End_Date)
{
DateTime date1 = new DateTime(Asso_End_Date);
DateTime date2 = DateTime.Now;
long result;
result = date2.Date.CompareTo(date1.Date);
return(result);
}]]>
</msxsl:script>
<!-- TEMPLATE #1 -->
  <xsl:template match="node()|@*">
    <xsl:copy>
      <xsl:apply-templates select="node()|@*"/>
    </xsl:copy>
  </xsl:template>

<!-- TEMPLATE #2 -->
<xsl:template name="mode1">
  <xsl:apply-templates select="Product_To_Product[Association_End_Date]"/>
</xsl:template>
<xsl:template name="mode2">
<xsl:variable name="date"/><xsl:value-of select="Product_To_Product[Association_End_Date]"/>
<xsl:choose>
    <xsl:when test="cs:compareDate($date) &gt; 0">
        <xsl:call-template name='mode1'/>
    </xsl:when>
    <xsl:otherwise>
    </xsl:otherwise>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>

Answer 1

您的XSLT存在许多问题。首先，正如Lingamurthy CS在评论中所提到的，你有一个名为mode2的命名模板，但没有任何东西在调用该模板，因此它永远不会被使用。它应该真的改为模板匹配

<xsl:template match="Product_To_Product[Association_End_Date]">

其次，您对定义date变量的方式存在疑问。

 <xsl:variable name="date"/>

换句话说，你没有定义它。它实际上是空的。变量声明后面的xsl:value-of根本不会影响它。你应该这样定义

<xsl:variable name="date" select="Association_End_Date"/>

第三，您的C＃函数本身存在问题

public static long compareDate(long Asso_End_Date)

参数的类型为long，但您不是传递long，而是传递字符串。该函数应该看起来像这样，因此它可以解析字符串

public static long compareDate(string Asso_End_Date)
{
DateTime date1 = DateTime.Parse(Asso_End_Date);
DateTime date2 = DateTime.Now;
long result;
result = date2.Date.CompareTo(date1.Date);
return(result)
}

另外，在查看通话结果时，您可能需要将>替换为<。

试试这个XSLT（还要注意不需要mode1模板。

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:fo="http://www.w3.org/1999/XSL/Format" xmlns:msxsl="urn:schemas-microsoft-com:xslt" exclude-result-prefixes="msxsl" xmlns:cs="urn:cs">
<xsl:output method="xml" version="1.0" encoding="UTF‐8" indent="yes"/>
<msxsl:script language="C#" implements-prefix="cs">
 <![CDATA[public static long compareDate(string Asso_End_Date)
{
DateTime date1 = DateTime.Parse(Asso_End_Date);
DateTime date2 = DateTime.Now;
long result;
result = date2.Date.CompareTo(date1.Date);
return(result);
}]]>
</msxsl:script>

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

  <xsl:template match="Product_To_Product[Association_End_Date]">
    <xsl:variable name="date" select="Association_End_Date"/>
    <xsl:choose>
        <xsl:when test="cs:compareDate($date) &lt;= 0">
          <xsl:call-template name="identity" />
        </xsl:when>
        <xsl:otherwise>
        </xsl:otherwise>
    </xsl:choose>
  </xsl:template>
</xsl:stylesheet>

或者更好的是，将条件放在模板匹配中，以简化它：

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:fo="http://www.w3.org/1999/XSL/Format" xmlns:msxsl="urn:schemas-microsoft-com:xslt" exclude-result-prefixes="msxsl" xmlns:cs="urn:cs">
<xsl:output method="xml" version="1.0" encoding="UTF‐8" indent="yes"/>
<msxsl:script language="C#" implements-prefix="cs">
 <![CDATA[public static long compareDate(string Asso_End_Date)
{
DateTime date1 = DateTime.Parse(Asso_End_Date);
DateTime date2 = DateTime.Now;
long result;
result = date2.Date.CompareTo(date1.Date);
return(result);
}]]>
</msxsl:script>

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

  <xsl:template match="Product_To_Product[cs:compareDate(Association_End_Date) &gt; 0]" />
</xsl:stylesheet>
