输出几乎是好的。我需要在grossVolume节点中获得所有＆＃34; Gross＆＃34;的总和。同一ArticleNr的节点。所以，我的输出将是：

 <grossVolume>6500;500</grossVolume>
 <product>316442;316495</product>

因为对于ArticleNr - 89CMID - ，我们的总和值为2700 + 1700 + 2100 = 6500。

基本上，对于所有＆＃34; ArticleNr＆＃34;如果节点具有相同的值，我需要将它们各自的所有数字相加＆＃34; Gross＆＃34;节点，然后生成一个输出，我们连接这些总和。对于Product节点输出，我连接了所需的值，并且它可以工作，我需要在grossVolume节点中也有类似的信息。

谢谢！

您不能在同一条指令中执行sum()和concat()，因为它会为字符串和数字组合引发错误。总和必须存储在局部变量中，然后用于与其他总和连接以形成<grossVolume>的值。

请更改for-each

的TL循环

<xsl:for-each select="TL[generate-id() = generate-id(key('Article', .//ArticleNr)[1])]">
    <grossVolume>
        <xsl:value-of select="sum(concat(.,';'))"/>
    </grossVolume>
</xsl:for-each>

到以下代码段

<grossVolume>
    <xsl:for-each select="TL[generate-id() = generate-id(key('Article', ./ArticleNr)[1])]">
        <xsl:variable name="sumGross" select="sum(key('Article', ./ArticleNr)/Gross)" />
        <xsl:value-of select="$sumGross" />
        <xsl:if test="position() != last()">
            <xsl:value-of select="';'" />
        </xsl:if>
    </xsl:for-each>
</grossVolume>

输出

<grossVolume>6500;500</grossVolume>

XSLT按名称和总和值分组
