总结两个数组中的XML数据

我对XSL和XML非常陌生，希望有一个简单的问题。我有一个XML文件，其中有两个数组，我需要总结。这里是XML文件的一部分总结两个数组中的XML数据

我真正想要的是来自两个Intensity数组的要素的总和加起来。因此，这将是这样的：

FirstArray [0] + SecondArray [0] =总和[0]，这是真的

105.84667205810547 + 1.0229243040084839 = 106.8696 和

FirstArray [1] + SecondArray [1] =总和[1]

105.83854675292969+ 48.868541717529297 = 154.7071等等...

有在这两个，我需要忽略现在之间的一些其他物品。

谢谢！

更新：

看sum功能，例如：

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> 
    <xsl:output omit-xml-declaration="yes" indent="yes"/> 

    <xsl:key name="k" match="Intensity" use="count(preceding-sibling::Intensity)"/> 

    <xsl:template match="/"> 
    <root> 
     <xsl:apply-templates select="//Intensity[generate-id(.) = 
          generate-id(key('k', count(preceding-sibling::Intensity)))]"/> 
    </root> 
    </xsl:template> 

    <xsl:template match="Intensity"> 
    <sum> 
     <xsl:value-of select="sum(key('k', count(preceding-sibling::Intensity)))"/> 
    </sum> 
    </xsl:template> 

</xsl:stylesheet>

这个模板总结两个IntensityArrayIntensity元素。

输出：

基里尔喜 - 我想我并不清楚。我需要每个元素的总和，而不是整个数组。所以105.8466721 + 1.022924304然后105.8385468 + 48.86854172等... – user918967

@ user918967，我已经更新了我的答案。 –

@downvoter，小心点评？ –

执行以下操作做你需要它？

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> 
    <xsl:output omit-xml-declaration="yes" indent="yes"/> 

    <xsl:template match="/"> 
    <root> 
     <xsl:apply-templates select="//ItemCollection"/> 
    </root> 
    </xsl:template> 

    <xsl:template match="ItemCollection"> 
    <xsl:variable name="itemCollection" select="." /> 
    <xsl:variable name="itemsCount" select="count((.//IntensityArray)[1]//Intensity)" /> 

    <xsl:for-each select="1 to $itemsCount"> 
     <xsl:variable name="itemIndex" select="." /> 
     <sum position="{$itemIndex}"> 
     <xsl:value-of select="sum($itemCollection//IntensityArray//Intensity[$itemIndex])" /> 
     </sum> 
    </xsl:for-each> 
    </xsl:template> 

</xsl:stylesheet>

我得到了下面的输出，当我跑在你的样本数据：

Hi Luke，在EditX 2010中运行您的代码我在表达式1中获得以下错误$ itemsCount：意外的令牌超出表达式 – user918967

奇怪的是，它在撒克逊的工作很好。由于EditiX 2010明显支持XPath 2.0，如果将''元素的'version'属性更改为'2.0'，会有帮助吗？ –

嗨卢克 - 是的伎俩！ – user918967

这种转变产生想要的结果，即使在珊瑚礁两个节点集有不同数量的节点和/或一些在第二节点集合中的节点的不具有值，该值是可浇注到一个号码：

<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> 
<xsl:output omit-xml-declaration="yes" indent="yes"/> 
<xsl:strip-space elements="*"/> 

<xsl:variable name="vArr1" select= 
    "/*/*/*/Item[1]/*/IntensityArray/*"/> 
<xsl:variable name="vArr2" select= 
    "/*/*/*/Item[2]/*/IntensityArray/*"/> 

<xsl:variable name="vShorterArr" select= 
    "$vArr1[not(count($vArr1) > count($vArr2))] 
    | 
    $vArr2[not(count($vArr2) >= count($vArr1))] 
    "/> 

<xsl:variable name="vLongerArr" select= 
    "$vArr2[not(count($vArr1) > count($vArr2))] 
    | 
    $vArr1[not(count($vArr2) >= count($vArr1))] 
    "/> 

<xsl:template match="/"> 
    <summedIntensities> 
     <xsl:apply-templates select="$vLongerArr"/> 
    </summedIntensities> 
</xsl:template> 

<xsl:template match="Intensity"> 
    <xsl:variable name="vPos" select="position()"/> 
    <Intensity> 
    <xsl:variable name="vVal2" select="$vShorterArr[position()=$vPos]"/> 
    <xsl:value-of select= 
    ". 
    + 
     concat('0', 
      substring($vVal2, 
         1 div (number($vVal2) = number($vVal2)) 
         ) 
      ) 
    "/> 
    </Intensity> 
</xsl:template> 
</xsl:stylesheet>

    </Root> 
</out_xml>

想要的，正确的结果产生：

    <Intensity>105.37964630126953</Intensity> 
</summedIntensisites>

说明：

定义了两个变量，每个变量都包含编译“数组”的节点。
定义了另外两个变量：$vShorterArr，包含较短的节点集和$vLongerArr包含较长的节点集。
模板适用于较长的节点集。
较长节点集合中的每个节点与较短节点集合中相应（如果存在）节点相加，或与0相加，否则为0。

二， XSLT 2.0溶液：

<xsl:stylesheet version="2.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
xmlns:xs="http://www.w3.org/2001/XMLSchema"> 
<xsl:output omit-xml-declaration="yes" indent="yes"/> 
<xsl:strip-space elements="*"/> 

<xsl:variable name="vArr1" select= 
    "/*/*/*/Item[1]/*/IntensityArray/*/number()"/> 
<xsl:variable name="vArr2" select= 
    "/*/*/*/Item[2]/*/IntensityArray/*/number()"/> 

<xsl:variable name="vShorterArr" select= 
    "if(count($vArr1) lt count($vArr2)) 
    then $vArr1 
    else $vArr2 
    "/> 
<xsl:variable name="vLongerArr" select= 
    "if(count($vArr1) ge count($vArr2)) 
    then $vArr1 
    else $vArr2 
    "/> 

<xsl:template match="/"> 
    <summedIntensities> 
     <xsl:for-each select="$vLongerArr"> 
      <xsl:variable name="vPos" select="position()"/> 
      <Intensity> 
      <xsl:variable name="vVal2" select= 
       "$vShorterArr[$vPos]"/> 
      <xsl:sequence select= 
      ". 
      + 
       (if($vVal2 castable as xs:double) 
       then $vVal2 
       else 0 
       ) 
      "/> 
      </Intensity> 
     </xsl:for-each> 
    </summedIntensities> 
</xsl:template> 
</xsl:stylesheet>

III。使用FXSL：

这是很容易使用的FXSL的f:zip-with()功能/模板来解决这个问题。

下面是一个使用FXSL 2一个解决方案：

<xsl:stylesheet version="2.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
xmlns:f="http://fxsl.sf.net/" 
exclude-result-prefixes="f" 
> 
    <xsl:import href="../f/func-zipWithDVC.xsl"/> 
    <xsl:import href="../f/func-Operators.xsl"/> 

    <!-- To be applied on numList.xml --> 
    <xsl:output omit-xml-declaration="yes" indent="yes"/> 

    <xsl:template match="/"> 
    <summedIntensities> 
     <xsl:for-each select= 
     "f:zipWith(f:add(), 
       /*/*/*/Item[1]/*/IntensityArray/*/number(), 
       /*/*/*/Item[2]/*/IntensityArray/*/number() 
       )" 
     > 
     <Intensity> 
     <xsl:sequence select="."/> 
     </Intensity> 
     </xsl:for-each> 
    </summedIntensities> 
    </xsl:template> 
</xsl:stylesheet>

我真正的XML文档比较复杂。有几个运行产生我需要总结的数组对。所有这些都可以嵌套在for-each循环中吗？ – user918967

@ user918967：不需要'xsl：for-each'只是推动你的函数'zip-with（）'，或者使用FXSL提供的函数。 –

我正在查看代码，Dimitre我认为你更容易使用，当我正在寻找一对称为Item name =“BaseLineOffSet”和Item name =“DispIntervalsMaxValues”的Intensity数组并忽略所有Intensity数组时。 Dmimitre，我将如何修改变量以仅获取这两个数组？ – user918967
