我在尝试处理具有递归标签的 XML 时遇到了两个问题（相同的标签在标签内重复）。

问题 #1 “标题：”部分输出所有标题标签的文本连接，就好像它是从 / 而不是调用它的路径搜索。

问题 #2 @id 测试什么也没找到，这可能是同一问题的症状。

这是 XSL：

<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:cog="http://developer.cognos.com/schemas/xmldata/1/" xmlns:xs="http://www.w3.org/2001/XMLSchema-instance"> 
<xsl:template match="/">
<xsl:template match="cog:rows">
    <xsl:apply-templates select="cog:rowEdge"/>
</xsl:template>
<xsl:template match="cog:rowEdge">
    <p><b>Caption:</b> <xsl:value-of select="cog:caption"/></p>
    <xsl:if test="@id">
        <b>id:</b> <xsl:value-of select="@id"/><br/>
    </xsl:if>
    <xsl:if test="cog:rowEdge">
        <p>Looking at next rowEdge</p>
        <xsl:apply-templates select="cog:rowEdge"/>
    </xsl:if>
</xsl:template>
<html>
<head><title>%s</title></head>
<body>
    <xsl:apply-templates select="cog:dataset/cog:crosstab/cog:rows"/>
</body>
</html>
</xsl:template>
</xsl:stylesheet>

这是 XML：

<?xml version="1.0" encoding="utf-8" ?>

您的样式表无效，因为文档节点的模板包含所有其他模板。模板是 XSLT 中的顶级元素，不能嵌套。如果将它们分开，样式表应该按预期工作：

<xsl:stylesheet version="1.0" 
   xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
   xmlns:cog="http://developer.cognos.com/schemas/xmldata/1/" 
   xmlns:xs="http://www.w3.org/2001/XMLSchema-instance"> 

   <xsl:template match="/">
      <html>
         <head><title>%s</title></head>
         <body>
            <xsl:apply-templates select="cog:dataset/cog:crosstab/cog:rows"/>
         </body>
      </html>
   </xsl:template>

   <xsl:template match="cog:rows">
      <xsl:apply-templates/>
   </xsl:template>

   <xsl:template match="cog:rowEdge">
      <p><b>Caption:</b> <xsl:value-of select="cog:caption"/></p>
      <xsl:if test="@id">
         <b>id:</b> <xsl:value-of select="@id"/><br/>
      </xsl:if>
      <xsl:if test="cog:rowEdge">
         <p>Looking at next rowEdge</p>
         <xsl:apply-templates select="cog:rowEdge"/>
      </xsl:if>
   </xsl:template>
</xsl:stylesheet>
