Question

Firefox告诉我“XSLT转换过程中出错：XSLT转换失败。”对于使用以下XSL文件的XML文件：

<?xml version='1.0' encoding='UTF-8'?>
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:dxp='http://schemas.google.com/analytics/2009' 
xmlns:gd='http://schemas.google.com/g/2005'
xmlns:fn='http://www.w3.org/2005/xpath-functions'>
<xsl:output method="html"/>
<xsl:template match="/">
<html><head><title>...</title></head><body>
<table frame='border' rules='all'>
<tr><th>site</th><th>week</th><th>pages</th><th>pageviews</th></tr>
<xsl:for-each select='feeds/feed/week'>
  <xsl:for-each-group select='entry' group-by='fn:concat(
    if (fn:matches(dxp:dimension[@name="ga:pagePath"]/@value, "^/sales"))
      then "/sales"
      else "non-/sales",
    " referred from ",
    if (fn:matches(dxp:dimension[@name="ga:referralPath"]/@value, "^/forsale"))
      then "/forsale"
      else "non-/forsale"
    )'>
    <tr>
      <td><xsl:value-of select='../dxp:tableName'/></td>
      <td>
        <xsl:value-of select='../dxp:startDate'/>-<xsl:value-of select='../dxp:endDate'/>
      </td>
      <td><xsl:value-of select='current-grouping-key()'/></td>
      <td><xsl:value-of select="sum(current-group()/dxp:metric/@value)"/></td>
    </tr>
  </xsl:for-each-group>
</xsl:for-each>
</table></body></html>
</xsl:template>
</xsl:stylesheet>

我无法弄清楚这可能是什么问题。有人知道吗？

（显然，如果我需要进一步的信息以便有人能够回答这个问题，我会很高兴提供这些信息：请评论要求它。我甚至不知道可能会有什么样的信息很有帮助。）

编辑：有人在答案中提到我的XML文件可能会有所帮助。它很长，但它的一般结构是：

<?xml-stylesheet type='text/xsl' href='./foo.xsl'?>

Answer 1

为什么你认为Firefox使用XSLT 2.0处理器？

AFAIK，事实并非如此。

显然，当给定包含非XSLT 1.0指令的XSLT 2.0转换时，XSLT 1.0处理器会引发某种错误，例如<xsl:for-each-group>。

Answer 2

你有一个示例xml文件在附近:) 可能有助于调查xsl的错误。

在我第一眼看到的时候，我看到了一个命名空间前缀ga，在xsl的xsl：stylesheet元素的命名空间列表中没有提到。

我还怀疑xsl：for-each-group中的group-by属性是否有效。看起来你试图通过连接一些xpath结果来动态设置group-by属性的值来组成一个xpath表达式。这是不可能的。

“XSLT转型失败”为什么？
