Question

had posted the question before concerning counting; am looking for a way of how to come up with the average height of the international and as well a high-low function displaying the height from the tallest to smallest…

<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl" href="soccer.xslt"?>
<footballclub>
    <player>
        <based>international</based>
        <height>5.5</height >
        <build>medium</build>
        <age>24</age>
    </player>
    <player>
        <based>local</based>
        <height>5.5</height >
        <build>medium</build>
        <age>24</age>
    </player>
    <player>
        <based>international</based>
        <height>5.5</height >
        <build>medium</build>
        <age>24</age>
    </player>
    <player>
        <based>local</based>
        <height>5.5</height >
        <build>medium</build>
        <age>24</age>
    </player>
    <player>
        <based>local</based>
        <height>7.5</height >
        <build>medium</build>
        <age>34</age>
    </player>
    <player>
        <based>international</based>
        <height>5.9</height >
        <build>large</build>
        <age>26</age>
    </player>
</footballclub>

This transformation:

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

 <xsl:variable name="vInter" select="/*/*[based='international']"/>

 <xsl:template match="/">
     Average height: <xsl:copy-of select="sum($vInter/height) div count($vInter)"/>

     Height high to low:<xsl:text/>

     <xsl:for-each select="$vInter/height">
       <xsl:sort data-type="number" order="descending"/>
       <xsl:value-of select="concat('&#xA;      ', .)"/>
     </xsl:for-each>
 </xsl:template>
</xsl:stylesheet>

when applied on the provided XML document:

<footballclub>
    <player>
        <based>international</based>
        <height>5.5</height >
        <build>medium</build>
        <age>24</age>
    </player>
    <player>
        <based>local</based>
        <height>5.5</height >
        <build>medium</build>
        <age>24</age>
    </player>
    <player>
        <based>international</based>
        <height>5.5</height >
        <build>medium</build>
        <age>24</age>
    </player>
    <player>
        <based>local</based>
        <height>5.5</height >
        <build>medium</build>
        <age>24</age>
    </player>
    <player>
        <based>local</based>
        <height>7.5</height >
        <build>medium</build>
        <age>34</age>
    </player>
    <player>
        <based>international</based>
        <height>5.9</height >
        <build>large</build>
        <age>26</age>
    </player>
</footballclub>

produces the wanted, correct result:

     Average height: 5.633333333333333

     Height high to low:
        5.9
        5.5
        5.5
