啟用PHP5 XML / XSL

有什么想法嗎？ 有什么明顯的東西嗎？

Answer 1

一種可能性是XSL處理器確實在抱怨  沒有被宣布為實體。 嘗試將文檔類型更改為

<!DOCTYPE xsl:stylesheet [ <!ENTITY nbsp '&#160;'> ] >

Answer 2

您的樣式表無效XSLT 1.0：模式中不能有變量/參數引用

您可以在XSLT 2.0模式中使用變量/參數引用。

按照@abc的建議，您需要在內容模板中通過該測試。

Answer 3

查看此錯誤：警告：XSLTProcessor :: importStylesheet（）[xsltprocessor.importstylesheet]：編譯錯誤：文件/protocols.xsl第24行/transform.php中的第18行元素模板

在第18行上，您具有：

<xsl：template match =“ page / section [@ id = $ sectionNumber ]”> // LINE 18

$ sectionNumber在哪里定義？ PHP無法看到它。

Answer 4

我遇到過同樣的問題，如果您使用參數調用XSL，則在XSLTProcessor中似乎是一個問題，請在`

<template match="/"><xsl:parameter name="whatever"/">

然后您可以調用xslt->setParameter ，它在apache日志中給出了錯誤，但似乎可以正常工作！

Answer 5

這里同樣的問題。 我通過將“ xsl：if”節點包含在“ xsl：template”節點中來解決此問題。 在您的情況下，它會給出：

<xsl:template match="page/section"> // LINE 18
    <xsl:if test="@id=$sectionNumber">
        <xsl:apply-templates select="protocol[@id=$protocolNumber]"/>
    </xsl:if>
</xsl:template>

<xsl:template match="protocol"> // LINE 22
    <xsl:if test="@id=$protocolNumber">
        <h4>(<xsl:value-of select="$sectionNumber"/>.<xsl:value-of select="@id"/>)&nbsp;<xsl:value-of select="@title"/></h4>
        <!-- Applies templates to all child elements -->
        <ol><xsl:apply-templates/></ol>
    </xsl:if>
</xsl:template>

Answer 6

在我看來，$ _GET ['xsl']為空。

Answer 7

您的xsl錯誤。 將其加載到XSLTProcessor對象時，它會失敗。 因此，您不能將其應用於xml。
