聚合属性值和复制整个XML结构的问题

我有以下XML文档：

<PrintOut>
<Header DateCreated="20010101" Status="1" />
<CalcInfo NetPrice="30222" DiscountPercent="0.05"  />
<OrderRows>
    <OrderRow RowID="11297" NbrOf="1">
        <RowCalcInfo GrossProfit="33.01" ListPrice="1555"/>
        <OrderSettings>
            <OrderSetting ParameterValue="1"/>
            <OrderSetting ParameterValue="2"/>

            </ComponentData>
        </Components>
    </OrderRow>
</OrderRows>
</PrintOut>

对于每个OrderRow，我想分组和汇总唯一的PropertyID的属性值（在element属性中找到）。每个PropertyID的PropertyValue的总数应该在元素OrderRow中创建为新属性，包括后缀＆＃34; _Sum＆＃34;。 解决方案应该能够提前处理PropertyID未知。 我正在寻找的是这样的：

    </OrderRows>
</PrintOut>

在这个例子中，我要总结的PropertyID是内部，costprice1，pricecost和internalprice。 我几乎得到了一个解决方案，我的xslt但不完全，因为摘要也最终作为元素属性的属性，可能不是XML文档的整个结构。我的XSLT：

    <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
    <xsl:output method="xml" encoding="UTF-8" indent="yes"/>

    <xsl:key name="currency-key"
             match="/PrintOut/OrderRows/OrderRow/Components/ComponentData/Properties/Property"
             use="@PropertyID" />
<xsl:template match="node()|@*">
   <xsl:copy>
    <xsl:apply-templates select="node()|@*"/>
   </xsl:copy>
 </xsl:template>

    <xsl:template match="OrderRow">
        <xsl:copy>
            <xsl:apply-templates select="Components/ComponentData/Properties/Property[generate-id() = generate-id(key('currency-key', @PropertyID)[1])]" />
            <xsl:apply-templates select="node()|@*"/>
        </xsl:copy>
    </xsl:template>

    <xsl:template match="Property">
        <xsl:attribute name="{concat(@PropertyID, '_Sum')}">
            <xsl:value-of select="sum(key('currency-key', @PropertyID)/@PropertyValue)" />
       </xsl:attribute>
    </xsl:template>
</xsl:stylesheet>

解决方案应该是XSLT 1.0版（但是，我也很好奇2.0版本的解决方案） 有人对此有所了解吗？

答案 0 :(得分：0)

这样的事情对你有用吗？

XSLT 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:strip-space elements="*"/>

<xsl:key name="property" match="Property" use="concat(@PropertyID, ancestor::OrderRow/@RowID)" />

<!-- identity transform -->
<xsl:template match="@*|node()">
    <xsl:copy>
        <xsl:apply-templates select="@*|node()"/>
    </xsl:copy>
</xsl:template>

<xsl:template match="OrderRow">
    <xsl:copy>
        <xsl:copy-of select="@*"/>
        <xsl:for-each select="Components/ComponentData/Properties/Property[generate-id()=generate-id(key('property', concat(@PropertyID, ancestor::OrderRow/@RowID))[1])]">
            <xsl:attribute name="{@PropertyID}_Sum">
                <xsl:value-of select="sum(key('property', concat(@PropertyID, ancestor::OrderRow/@RowID))/@PropertyValue)" />
            </xsl:attribute>
        </xsl:for-each>
        <xsl:apply-templates/>
    </xsl:copy>
</xsl:template>

</xsl:stylesheet>

当应用于您的输入时，结果将是：

            </ComponentData>
         </Components>
      </OrderRow>
   </OrderRows>
</PrintOut>

在XSLT 2.0中，您将使用xsl:for-each-group进行分组，而不是使用Muenchian方法。
