Here's the solution using FXSL:

<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
>
   <xsl:import href="maximum.xsl"/>
   
   <xsl:output method="text"/>

    <xsl:template match="/">
      <xsl:call-template name="maximum">
        <xsl:with-param name="pList" select="/books/book/price"/>
      </xsl:call-template>
    </xsl:template>
</xsl:stylesheet>


When this transformation is applied on the following source xml:

<books>
  <book>
    <price>20</price>
  </book>
  <book>
    <price>10</price>
  </book>
  <book>
    <price>30</price>
  </book>
  <book>
    <price>15</price>
  </book>
</books>

the result is:

30
