当时间戳 = 00:00 时需要中断。我曾尝试使用位置、变量等，但我对此太陌生了，不知道我做错了什么！这是我的代码：

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:template match="node()">
    <xsl:copy>
        <xsl:copy-of select="@*"/>
        <xsl:apply-templates/>
    </xsl:copy>
</xsl:template>
<xsl:template match="Data">
    <xsl:copy-of select="@*"/>
    <xsl:variable name="cutoff"/>
    <xsl:if test="Reading[contains(@TimeStamp,'01:00')]">
        <xsl:value-of select="Reading[@TimeStamp]"/>
    </xsl:if>
    <xsl:apply-templates select="Reading[position() mod 24 = 1]">
        <xsl:with-param name="pos" select="$cutoff"/>
    </xsl:apply-templates>
</xsl:template>
<xsl:template match="Reading">
    <xsl:param name="pos"/>
    <Data>
        <xsl:copy-of select=".|following-sibling::*[position() &lt; pos]"/>
    </Data>
</xsl:template>

请帮忙！
