Question

我有以下节点结构，我需要在XSLT中的所有<FTACERTEXPIRATIONDATE>中获取最大<partSupplierFTA>。有人可以帮帮我吗？

Answer 1

这将使用XSLT2找到最新日期。如果您需要找到包含<SupplierFTA>节点，这应该为您提供一个起点。

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:xs="http://www.w3.org/2001/XMLSchema"
    version="2.0">
    <xsl:variable name="a" select="//FTACERTEXPIRATIONDATE/text()"/>
    <xsl:template match="root">
        <xsl:value-of select="max(for $x in $a return xs:date(replace($x,'^([0-9]+)/([0-9]+)/([0-9]+)$','$3-$1-$2')))"/>
    </xsl:template>
</xsl:stylesheet>

Answer 2

虽然效率很低，但您可以使用xsl:for-each并按年，月和日对值进行排序，然后选择第一项：

<xsl:for-each select="
        /modelMasterHeader/modelMaster/Supplier/SupplierFTA/FTACERTEXPIRATIONDATE
        ">
    <xsl:sort order="descending" data-type="number" 
        select="substring-after(substring-after(., '/'), '/')"/>
    <xsl:sort order="descending" data-type="number" 
        select="substring-before(substring-after(., '/'), '/')"/>
    <xsl:sort order="descending" data-type="number" 
        select="substring-before(.,'/')"/>
    <xsl:if test="position()=1">
        <xsl:value-of select="."/>
    </xsl:if>
</xsl:for-each>

使用XSLT进行XML转换，需要从多个复杂类型中获取max expirationdate
