选择XSLT1.0或2.0后进行Concate

对于这个论坛和XSLT来说还是新的，已经搜索过了，但是找不到正确的解决方案

我试图在选择后得到正确的concat，如果我符合条件208或906仍然是get LX1234作为组合，它总是以另一个作为解决方案结束。XSLT是在2.0中构建的，因此这两种解决方案都适用于我

<xsl:for-each select="XXX/Envelope/PickingList/Line/Lot">
                <articleLine type="tag">
                    <articleCode>
                        <xsl:choose>
                            <xsl:when test="XXX/Envelope/GLN_Supplier =208">

                                 <xsl:value-of select="concat('AV',../ArticleCodeSupplier)"/> 
                            </xsl:when>
                            <xsl:when test="XXX/Envelope/GLN_Supplier =906">

                                <xsl:value-of select="concat('KR',../ArticleCodeSupplier)"/> 
                            </xsl:when>
                            <xsl:otherwise>
                                 <xsl:value-of select="concat('LX',../ArticleCodeSupplier)"/>

                            </xsl:otherwise>
                        </xsl:choose>
                    </articleCode>

说明：

<xsl:for-each select="XXX/Envelope/PickingList/Line/Lot">

将返回false，因为路径

XXX/Envelope/GLN\u供应商
未选择任何内容。如果将路径设置为绝对路径，则会得到不同的结果：

 <xsl:when test="/XXX/Envelope/GLN_Supplier =208">

请显示XML输入-请参见：。亲爱的Michael，这将起作用，但正如您所提到的，效率总是比XSLT好，我只是从XSLT开始，所以我不知道如何做到这一点。请参见我答案的补充部分。请注意，如果每条
线路
都有一个
批次
，您可以进一步简化它。我开始时每条线路都有一个批次，但客户让我惊讶的是，每条线路都可能有多个批次。谢谢你的时间和帮助，我又学到了一些东西，希望其他人也能从中学到一些东西。但是你没有从中吸取任何东西。如果一行有两个批次，结果将显示两个相同的
articleLine
双胞胎。
