我有一个像这样的xml:
<Ownership_Shareholders_S>
<Ownership_Shareholders>
<CUSTOMER_31>A</CUSTOMER_31>
<PERCENT_NAME_OF_OWNERS_32>40%</PERCENT_NAME_OF_OWNERS_32>
</Ownership_Shareholders>
<Ownership_Shareholders COLL_ID="1">
<CUSTOMER_31>A</CUSTOMER_31>
<PERCENT_NAME_OF_OWNERS_32>30%</PERCENT_NAME_OF_OWNERS_32>
</Ownership_Shareholders>
<Ownership_Shareholders COLL_ID="2">
<CUSTOMER_31>B</CUSTOMER_31>
<PERCENT_NAME_OF_OWNERS_32>20%</PERCENT_NAME_OF_OWNERS_32>
</Ownership_Shareholders>
<Ownership_Shareholders COLL_ID="3">
<CUSTOMER_31>B</CUSTOMER_31>
<PERCENT_NAME_OF_OWNERS_32>29%</PERCENT_NAME_OF_OWNERS_32>
</Ownership_Shareholders>
</Ownership_Shareholders_S>
我需要帮助来编写一个xslt来转换以下
中的这些数据A 40%
30%
B 20%
29%
因此,我需要按客户字段对数据进行分组。怎么办呢?

以下XSLT 2.0转换将按您的要求执行:
XSLT:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0">
<xsl:output method="text"/>
<xsl:template match="@*|node()">
<xsl:apply-templates select="@*|node()"/>
</xsl:template>
<xsl:template match="Ownership_Shareholders_S">
<xsl:for-each-group select="Ownership_Shareholders" group-by="CUSTOMER_31">
<xsl:value-of select="current-grouping-key()"/>
<xsl:text> </xsl:text>
<xsl:value-of select="current-group()/PERCENT_NAME_OF_OWNERS_32"
separator="
 "/>
<xsl:text>
</xsl:text>
</xsl:for-each-group>
</xsl:template>
</xsl:stylesheet>
<强>输出:强>
A 40%
30%
B 20%
29%
如果您只能使用XSLT 1.0,请告诉我们!
这是一个XSLT 1.0转换。通常,在XSLT 2.0中使用for-each-group
时,您通常可以在XSLT 1.0中使用Muenchian grouping method执行相同的操作:
<强> XSLT:强>
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output method="text"/>
<xsl:key name="customer" match="Ownership_Shareholders" use="CUSTOMER_31"/>
<xsl:template match="Ownership_Shareholders_S">
<xsl:for-each select="Ownership_Shareholders[
generate-id() = generate-id(key('customer', CUSTOMER_31)[1])
]">
<xsl:value-of select="CUSTOMER_31"/>
<xsl:text> </xsl:text>
<xsl:for-each select="key('customer', CUSTOMER_31)">
<xsl:value-of select="PERCENT_NAME_OF_OWNERS_32"/>
<xsl:text>
</xsl:text>
<xsl:if test="position() != last()">
<xsl:text> </xsl:text>
</xsl:if>
</xsl:for-each>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>

只是为了好玩,紧凑的XSLT 1.0:
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output method="text"/>
<xsl:key name="kCustomerByValue" match="CUSTOMER_31" use="."/>
<xsl:template match="text()"/>
<xsl:template match="CUSTOMER_31[count(.|key('kCustomerByValue',.)[1])=1]">
<xsl:for-each select="key('kCustomerByValue',.)">
<xsl:value-of select="concat(substring(concat(.,' '),
1+(position()!=1),
1),
' ',
../PERCENT_NAME_OF_OWNERS_32,
'
')"/>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
一行XPath 2.0:
string-join(for $customer
in distinct-values(/Ownership_Shareholders_S
/Ownership_Shareholders
/CUSTOMER_31)
return /Ownership_Shareholders_S
/Ownership_Shareholders[CUSTOMER_31=$customer]
/PERCENT_NAME_OF_OWNERS_32
/concat(if (position()=1)
then $customer
else replace($customer,'.',' '),
' ',.),
'
')
