Xml XSLT 1.0嵌套分组、总和和计数

在XSLT1.0中，需要按地址分组，然后按部分和全部分组。当前，如果第一个地址元素中未包含该部分，则忽略该部分。这是很新的

输出为-

Total Units 7

name1address1
part1 Total Pallets : 1
part2 Total Pallets : 2

name2address2
part1 Total Pallets : 2
part2 Total Pallets : 1

应为-注意地址2中的第3部分

Total Units 7

name1address1
part1 Total Pallets : 1
part2 Total Pallets : 2

name2address2
part1 Total Pallets : 2
part2 Total Pallets : 1
part3 Total Pallets : 1

XML是-

<?xml version="1.0" encoding="UTF-8"?>
<dispatch>
    <delivery>
        <name>name2</name>
        <address>address2</address>
        <pallet>
            <part>part1</part>
        </pallet>
        <pallet>
            <part>part2</part>
        </pallet>
    </delivery>
    <delivery>
        <name>name1</name>
        <address>address1</address>
        <pallet>
            <part>part1</part>
        </pallet>
        <pallet>
            <part>part2</part>
        </pallet>
        <pallet>
            <part>part2</part>
        </pallet>
    </delivery>
    <delivery>
        <name>name2</name>
        <address>address2</address>
        <pallet>
            <part>part1</part>
        </pallet>
        <pallet>
            <part>part3</part>
        </pallet>
    </delivery>
</dispatch>

XSLT是-

您仅将托盘模板应用于名称/地址组中第一次交货的子项。尝试更改此选项：

<xsl:apply-templates
    select="pallet[generate-id(.)=generate-id(key('delivery_detail_part',concat(../name,../address,part))[1])]"> 
</xsl:apply-templates>

致：

<xsl:apply-templates
    select="key('delivery_detail', concat(name, address))/pallet[generate-id(.)=generate-id(key('delivery_detail_part',concat(../name,../address,part))[1])]">
</xsl:apply-templates>
