Question

已经在计数之前发布了问题;在寻找如何拿出与国际，以及高功能低显示从最高到最小高度的平均高度的方式...

<?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>

Answer 1

这种转变：

<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> 

当所提供的XML文档施加：

<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> 

产生想要的，正确的结果：

 Average height: 5.633333333333333 

    Height high to low: 
     5.9 
     5.5 
     5.5
