java - 使用 XSLT 转换 XML 时如何防止 fatal error

Question

我有以下 XSLT，使用此 XSLT 转换 XML 时会引发以下错误

<xsl:stylesheet>    
    <xsl:output method="xml" indent="yes" />

    <xsl:key name="k1" match="*" use="."/>
    <!-- <xsl:param name="string-value" select="'STRING_TO_FIND'"/> -->

    <xsl:template match="*">
        <rss>
            <xsl:copy-of select="key('k1', 'STRING_TO_FIND')"/>
        </rss>
    </xsl:template>
</xsl:stylesheet>

错误

ERROR:  'Could not compile stylesheet'
FATAL ERROR:  'The string "--" is not permitted within comments.'
           :The string "--" is not permitted within comments.

我在 XSLT 中替换了以下字符串来代替“STRING_TO_FIND”。该字符串可以动态生成。抛出上述错误的示例字符串如下。

                                    <description><![CDATA[                                          <p>LANSING, MI -- An unusual photo and an "off-the-cuff remark" in the Michigan House on Thursday sparked a war of words about the "war on women" that stretched far beyond the walls of the state Capitol.</p> <p>Republican state Reps.

如何消除这个错误？

Answer 1

您有一条格式为 <!-- <xsl:param name="string-value" select="'STRING_TO_FIND'"/> --> 的评论在样式表中，这是语法正确的注释。但是，如果您有 <!-- <xsl:param name="string-value" select="'--'"/> --> ，您有语法错误，请参阅 http://www.w3.org/TR/xml/#sec-comments其中说

For compatibility, the string " -- " (double-hyphen) MUST NOT occur within comments.

我不知道你为什么注释掉 xsl:param但然后尝试操纵它，最简单的方法是删除 xsl:param而不是将其注释掉。

如果这个问题是 How to get XML element based on given value 的后续问题但是，看起来您想要查找具有复杂内容的元素，这与我在答案中提出的建议不符。
