  The interesting part is to get the right entries:

    ~/xslt/tests> cat number-ranges.xml
    <entries>
      <entry num="0"/>
      <entry num="1"/>
      <entry num="2"/>
      <entry num="3"/>
      <entry num="4"/>
      <entry num="5"/>
      <entry num="6"/>
      <entry num="7"/>
      <entry num="8"/>
    </entries>

    ~/xslt/tests> cat number-ranges.xsl
    <xsl:transform
        xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
        version="1.0">

      <xsl:output indent="yes" omit-xml-declaration="yes"/>

      <xsl:template match="/">
        <xsl:variable name="range" select="'1-5'"/>
        <xsl:variable name="down-limit" select="
            number(substring-before($range, '-'))"/>
        <xsl:variable name="up-limit" select="
            number(substring-after($range, '-'))"/>
        <xsl:copy-of select="
            entries/entry[ @num &gt;= $down-limit
                             and @num &lt;= $up-limit ]"/>
      </xsl:template>

    </xsl:transform>

    ~/xslt/tests> saxon number-ranges.xml number-ranges.xsl
    Warning: Running an XSLT 1.0 stylesheet with an XSLT 2.0 processor
    <entry num="1"/>
    <entry num="2"/>
    <entry num="3"/>
    <entry num="4"/>
    <entry num="5"/>
