预期的输出 XML 文件应该是:

推荐答案

看来我已经通过额外的实现解决了这个问题..
以下是新代码:-<代码>

It seems I have resolved this issue with an additional implementation..
Below is the new code:-

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:strip-space elements="*"/>
    <xsl:template match="*|@*">
        <xsl:copy-of select="preceding-sibling::node()[1]/self::comment()"/>
        <xsl:copy>
            <xsl:apply-templates select="@*"/>
            <xsl:apply-templates select="node()">
                <xsl:sort select="name()"/>
                <xsl:sort select="@*"/>
            </xsl:apply-templates>
        </xsl:copy>
    </xsl:template>
</xsl:stylesheet>
