Question

在给定的xml中，当ItemtypeCode值为＆＃39; S＆＃39;时，它应该检查重复＆＃39;原始顺序 - 否＆＃39;价值，如果找到，则删除相应的订单＆＃39; node，当ItemtypeCode值为＆＃39; R＆＃39;时，它可以允许重复。

请为此方案建议XSLT。在此先感谢！

XML

<orders> 
<order order-no="5000003324123">
<original-order-no>5000003324892</original-order-no>

  <custom-attribute attribute-id="itemTypeCode">S</custom-attribute>

这是一个分组问题，请参阅http://www.jenitennison.com/xslt/grouping/muenchian.xml，在XSLT 2.0中，您可以使用

解决它

<xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0">

    <xsl:key name="dupes"
        match="order[custom-attributes/custom-attribute[@attribute-id = 'itemTypeCode'] = 'S']"
        use="original-order-no"/>

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

    <xsl:template match="order[custom-attributes/custom-attribute[@attribute-id = 'itemTypeCode'] = 'S'][not(. is key('dupes', original-order-no)[1])]"/>

</xsl:transform>

使用XSLT 1.0，您需要将最后一个模板更改为

    <xsl:template match="order[custom-attributes/custom-attribute[@attribute-id = 'itemTypeCode'] = 'S'][not(generate-id() = generate-id(key('dupes', original-order-no)[1]))]"/>

使用XSLT删除特定于值的重复节点
