在xslt1.0中查找每个节点的不同值

Question

我想在每个节点中找到不同的值。但当我使用muenchian方法时，它将只在顶级选择不同的值。

目前我得到的输出为：

Bag 20
Tray 30

但我想为每个项目分组类型和数量

<!--for 1st item-->
Bag 20
Tray 30
<!--for 2nd item-->
Bag 20
Box 20
Tray 30

我正在做一些研究以使它发挥作用，但没有成功。

XML:

<?xml version="1.0" encoding="UTF-8"?>
<Test>
<Items>
<Item>
<name>A</name>
<type>Bag</type>
<input quantity="20"/>

</Item>
<Item>
<name>A</name>
<type>Bag</type>
<input quantity="20"/>

</Item>
<Item>
<name>B</name>
<type>Metal</type>
<input quantity="20"/>

</Item>
<Item>
<name>A</name>
<type>Tray</type>
<input quantity="30"/>

</Item>

</Items>
<Items>
<Item>
<name>A</name>
<type>Bag</type>
<input quantity="20"/>

</Item>
<Item>
<name>A</name>
<type>Box</type>
<input quantity="20"/>

</Item>
<Item>
<name>B</name>
<type>Metal</type>
<input quantity="20"/>

</Item>
<Item>
<name>A</name>
<type>Tray</type>
<input quantity="30"/>

</Item>

</Items>
</Test>

感谢你的帮助！

Answer 1

如果您想为每个Items分别找到name和type为A的不同Item，则需要在键中包含父Items'id。下面是一个简化的示例：

XSLT 1.0

<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="k" match="Item[name='A']" use="concat(type, '|', generate-id(..))"/>
<xsl:template match="/Test">
<root>
<xsl:for-each select="Items">
<xsl:comment>
<xsl:value-of select="position()" />
</xsl:comment>
<xsl:for-each select="Item[name='A'][count(. | key('k', concat(type, '|', generate-id(..)))[1]) = 1]">
<item>
<type>
<xsl:value-of select="type"/>
</type>
<quantity>
<xsl:value-of select="input/@quantity"/>
</quantity>
</item>
</xsl:for-each>
</xsl:for-each>
</root>
</xsl:template>
</xsl:stylesheet>

应用于您的输入示例，结果将是：

结果

<?xml version="1.0" encoding="UTF-8"?>
<root>
<!--1-->
<item>
<type>Bag</type>
<quantity>20</quantity>
</item>
<item>
<type>Tray</type>
<quantity>30</quantity>
</item>
<!--2-->
<item>
<type>Bag</type>
<quantity>20</quantity>
</item>
<item>
<type>Box</type>
<quantity>20</quantity>
</item>
<item>
<type>Tray</type>
<quantity>30</quantity>
</item>
</root>
