XSLT - 選擇最小值，最大值和平均屬性值 - 需要來自不同級別的數據

-1

我的問題是，該屬性位於需要選擇的節點下方的幾個節點上。另外，我需要從不同層面提取價值。不知道如何構建XPath。XSLT - 選擇最小值，最大值和平均屬性值 - 需要來自不同級別的數據

我需要選擇在Linux（平臺）運行所有圖形軟件（類別），我需要的最低，最高和平均價格（版本/ @價格）。這對我來說似乎很複雜，我真的需要一些幫助。

感謝，

好吧，這裏是爲我工作的最終XSLT。

你可以發佈你試過的'xslt'嗎？ – 2015-02-06 04:32:36

請說出您的XSLT版本的習慣。 – 2015-02-06 05:27:35

嗨邁克爾。對不起，我正在學習XSLT。我正在開發與VS 2013.我想看看我剛剛發佈的XSLT，它會是V1？ – 2015-02-07 00:31:29

，我需要選擇在Linux上（平臺）運行所有圖形軟件（類別），我需要的最低，最高和平均價格（版本/ @價格）。

如果像我懷疑，你正在使用XSLT 1.0，與EXSLT擴展功能的支持，試圖沿着線的東西：1.0

<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="/software_inventory"> 
    <xsl:variable name="selected-versions" select="software[category='Graphics' and support_platforms/platform='Linux']/Approved_Versions/Version" /> 
    <table border="1"> 
     <tr> 
      <th>Minimum</th> 
      <th>Maximum</th> 
      <th>Average</th>    
     </tr> 
     <tr> 
      <xsl:for-each select="$selected-versions"> 
       <xsl:sort select="@Price" data-type="number" order="ascending"/> 
       <xsl:if test="position()=1"> 
        <td><xsl:value-of select="@Price"/></td> 
       </xsl:if> 
       <xsl:if test="position()=last()"> 
        <td><xsl:value-of select="@Price"/></td> 
       </xsl:if> 
      </xsl:for-each> 
      <td><xsl:value-of select="sum($selected-versions/@Price) div count($selected-versions)"/></td> 
     </tr> 
    </table> 
</xsl:template> 

</xsl:stylesheet>

適用於

XSLT你的例子，結果將;

<?xml version="1.0" encoding="UTF-8"?> <table border="1"> <tr> <th>Minimum</th> <th>Maximum</th> <th>Average</th> </tr> <tr> <td>399</td> <td>1000000</td> <td>500199.5</td> </tr> </table>

不錯的XSLT代碼+1。 – 2015-02-06 16:28:01

XSLT - 選擇最小值，最大值和平均屬性值 - 需要來自不同級別的數據
