我的XML数据中有一个名为这个节点的节点,它包含一个唯一的值,比如45678。通过XSLT,如果在完整的数据集中不止一次(1)找到45678,我只想包含该节点的数据。最终结果可以修改现有节点,或者创建一个名为“新节点”的节点。此数据的最终结果将创建“带子的父”产品。productId值将所有类似的产品组合在一起,问题是,有时只有一个具有该键的产品,而我不应该创建一个父产品。
重要注意:为什么我这么挣扎,第一,我仍然是全新的XSL,第二,当前版本的引擎不允许我使用EXSLT,但它似乎我可以使用PHP,如果必要。
样本数据集
<productId>0243176820</productId> --您可以看到这个值被多次使用,在这种情况下,它应该包含在结果数据中,<productId>1136194258</productId>,但是这个值只包含一次。

要检查XSLT1.0中值的唯一性,可以使用对门窗群的稍微修改。
下面是一个最小示例:
XSLT1.0
<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:key name="part-by-product" match="part" use="productId" />
<xsl:template match="/root">
<items>
<xsl:for-each select="part[supplierNumber/text() and partStatusDescription != 'DISCONTINUED']">
<item>
<xsl:copy-of select="partNumber | productId"/>
<!-- check productId uniqueness -->
<xsl:if test="count(key('part-by-product', productId)) > 1">
<configurable_id>
<xsl:value-of select="productId"/>
</configurable_id>
</xsl:if>
</item>
</xsl:for-each>
</items>
</xsl:template>
</xsl:stylesheet>应用于输入示例,这将返回:
结果
<?xml version="1.0" encoding="UTF-8"?>
<items>
<item>
<partNumber>06012660</partNumber>
<productId>0243176820</productId>
<configurable_id>0243176820</configurable_id>
</item>
<item>
<partNumber>06012663</partNumber>
<productId>0243176820</productId>
<configurable_id>0243176820</configurable_id>
</item>
<item>
<partNumber>06011482</partNumber>
<productId>0635669078</productId>
</item>
