我尝试过孟奇式分组，但没有成功。
根据属性@htn进行分组的正确方式是什么XSLT？
定义xsl:key以根据@htn值对data元素进行分组：
<xsl:key name="data-by-htn" match="data" use="@htn" />
然后，您可以使用以下XPath表达式来检索@htn值的唯一列表：
data[count(. | key('data-by-htn', @htn)[1]) = 1]
这个XPath表达式也可以：
data[generate-id(.) = generate-id(key('data-by-htn', @htn)[1])]
应用于样式表：
<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output indent="yes" />
<xsl:key name="data-by-htn" match="data" use="@htn" />
<xsl:template match="search">
<data-grouped-by-htn>
<xsl:for-each select="data[
count(. | key('data-by-htn', @htn)[1])
= 1]">
<xsl:sort select="@htn" />
<!--Construct an element using the name of the @htn,
translate spaces into "_" in order to make it an allowable
element name -->
<xsl:element name="{translate(@htn, ' ','_')}">
<!--perserve the @htn for the new element -->
<xsl:copy-of select="@htn"/>
<!--Iterate over the list of rows
grouped for this @htn value -->
<xsl:for-each select="key('data-by-htn', @htn)">
<xsl:sort select="@id" />
<!--copy the data element into the output -->
<xsl:copy-of select="."/>
</xsl:for-each>
</xsl:element>
</xsl:for-each>
</data-grouped-by-htn>
</xsl:template>
</xsl:stylesheet>
当应用于示例XML时，它会生成以下输出，列出按@htn值分组的data元素：
<?xml version="1.0" encoding="UTF-16"?>
<data-grouped-by-htn>
