Question

我坚持在XSLT1.0中使用数组。我从未在XSLT中使用过数组。我需要将值存储在Array中并在以后使用它。事实上，我们需要使用数组位置

输入XML

<document>
<party>
    <gtin>1000909090</gtin>
    <pos>
        <attrGroupMany name="temperatureInformation">
            <row>
                <attr name="temperatureCode">STORAGE</attr>
                <attrQualMany name="temperature">
                    <value qual="FAH">10</value>
                </attrQualMany>
                <attrGroupMany name="temperatureStats">
                    <row>
                        <attr name="StatsCode">CODE1</attr>
                    </row>
                    <row>
                        <attr name="StatsCode">CODE2</attr>
                    </row>
                </attrGroupMany>
            </row>
            <row>
                <attr name="temperatureCode">HANDLING</attr>
                <attrQualMany name="temperature">
                    <value qual="FAH">30</value>
                </attrQualMany>
                <attrGroupMany name="temperatureStats">
                    <row>
                        <attr name="StatsCode">CODE3</attr>
                    </row>
                    <row>
                        <attr name="StatsCode">CODE4</attr>
                    </row>
                </attrGroupMany>
            </row>
        </attrGroupMany>
    </pos>
</party>
</document>

预期输出

我正在使用下面的XSLT。我编写了代码，除了代码在第一个数组中存储值，在第二个数组中从数组中检索。

<xsl:stylesheet 
version="1.0"

<xsl:output indent="yes"/>



<xsl:template match="document">

Answer 1

您可以创建一个命名模板来输出您尝试“存储”的值

<xsl:template name="ref">
    <xsl:value-of select="concat('temperatureInformation_details','-',attr[@name='temperatureCode'],'-',attrQualMany/@name,'-',attrQualMany/value/@qual,'-',attrQualMany/value,'-', position()    )"/>
</xsl:template>

然后在你的第二个xsl:for-each中，你可以将它存储在一个变量中，以便在内循环中使用

<xsl:variable name="data">
   <xsl:call-template name="ref" />
</xsl:variable>

试试这个XSLT

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes"/>

<xsl:template match="document"> 
    <CatalogItem>
        <RelationshipData>
            <Relationship>
                <RelationType>temperatureInformation_details</RelationType>  
                <RelatedItems>      
                    <xsl:for-each select="party/pos/attrGroupMany[@name ='temperatureInformation']/row">                        
                        <RelatedItem>
                            <xsl:attribute name="referenceKey">
                                <xsl:call-template name="ref" />
                            </xsl:attribute>

                        <xsl:variable name="data">
                            <xsl:call-template name="ref" />

                            <RelatedItem>
                                <xsl:attribute name="referenceKey">
                                    <xsl:value-of select="concat('temperatureStats','-',attr[@name='StatsCode'],'-', position(),'-', $v_temperatureInformation_position    )"/>
                                </xsl:attribute>    
                                <Attribute name="temperatureInformationreferenceKey">

        </RelationshipData>
    </CatalogItem>
</xsl:template> 

<xsl:template name="ref">
    <xsl:value-of select="concat('temperatureInformation_details','-',attr[@name='temperatureCode'],'-',attrQualMany/@name,'-',attrQualMany/value/@qual,'-',attrQualMany/value,'-', position()    )"/>
