[英]Grouping output using XSLT 1.0
I've been given the follow XML (produced by someone from an Excel spreadsheet) 我得到了以下XML(由Excel电子表格中的某人生成)
<Records>
<record>
<Domain>Domain 1</Domain>
<Section>Section A</Section>
<label>Option X 1</label>
<Keyword>Unique KW 1</Keyword>
<Control>Checkbox</Control>
<Default>TRUE</Default>
</record>
<record>
<Domain>Domain 1</Domain>
<Section>Section B</Section>
<label>Option X 2</label>
<Keyword>Unique KW 2</Keyword>
<Control>Checkbox</Control>
<Default>TRUE</Default>
</record>
<record>
<Domain>Domain 2</Domain>
<Section>Section A</Section>
<label>Option X 3</label>
<Keyword>Unique KW 3</Keyword>
<Control>Checkbox</Control>
<Default>TRUE</Default>
</record>
<record>
<Domain>Domain 1</Domain>
<Section>Section A</Section>
<label>Option X 4</label>
<Keyword>Unique KW 4</Keyword>
<Control>Checkbox</Control>
<Default>FALSE</Default>
</record>
<record>
<Domain>Domain 1</Domain>
<Section>Section B</Section>
<label>Option X 5</label>
<Keyword>Unique KW 5</Keyword>
<Control>Checkbox</Control>
<Default>TRUE</Default>
</record>
<record>
<Domain>Domain 2</Domain>
<Section>Section B</Section>
<label>Option X 6</label>
<Keyword>Unique KW 6</Keyword>
<Control>Checkbox</Control>
<Default>TRUE</Default>
</record>
<record>
<Domain>Domain 1</Domain>
<Section>Section A</Section>
<label>Option X 7</label>
<Keyword>Unique KW 7</Keyword>
<Control>Checkbox</Control>
<Default>TRUE</Default>
</record>
</Records>
And I've been asked to transform it into the following using XSLT 1.0 我被要求使用XSLT 1.0将其转换为以下内容
<Configuration>
<Domain name="Domain 1">
<Section name="Section A">
<Option keyword="Unique KW 1" name="Option X 1">
<Control type="Checkbox" default="True" />
</Option>
<Option keyword="Unique KW 3" name="Option X 3">
<Control type="Checkbox" default="True" />
</Option>
<Option keyword="Unique KW 7" name="Option X 7">
<Control type="Checkbox" default="True" />
</Option>
</Section>
<Section name="Section B">
<Option keyword="Unique KW 2" name="Option X 2">
<Control type="Checkbox" default="True" />
</Option>
<Option keyword="Unique KW 5" name="Option X 5">
<Control type="Checkbox" default="True" />
</Option>
</Section>
</Domain>
<Domain name="Domain 2">
<Section name="Section A">
<Option keyword="Unique KW 3" name="Option X 3">
<Control type="Checkbox" default="True" />
</Option>
</Section>
<Section name="Section B">
<Option keyword="Unique KW 6" name="Option X 6">
<Control type="Checkbox" default="True" />
</Option>
</Section>
</Domain>
</Configuration>
I've used XSLT in a limited capacity in the past but I'm struggling getting a single element out (eg Domain and Section), the output I get is one per element in the source where I need 1 per value in the source (if that makes sense). 过去,我曾以有限的容量使用XSLT,但我一直在努力获取单个元素(例如Domain和Section),我得到的输出是源中每个元素一个,而我需要源中每个值一个(如果有道理)。 I just seem to get lots of
我似乎得到很多
Domain instead of just two (Domain 1 and Domain 2), same with the Section 域而不是两个(域1和域2),与Section相同
Is there any way of doing this with XSLT 1.0 or am I just wasting my time? 使用XSLT 1.0可以做到这一点吗?还是我只是在浪费时间?
(Also, the data I've given is an example, edited to remove sensitive data and size, there are far more Domains and Section etc) (此外,我提供的数据是一个示例,经过编辑以删除敏感数据和大小,还有更多的Domains和Section等)
(The little I've got so far) (到目前为止我所获得的很少)
<xsl:stylesheet version="1.0"

EDIT: After looking at Michaels link (thanks) I'm getting closer. 编辑:看了迈克尔斯的链接后(谢谢),我越来越近了。 The outer group (Domain) is working but the inner group isn't
外部组(域)正在工作,但是内部组没有
<xsl:key name="domain-name" match="record" use="Domain" />
<xsl:key name="section-name" match="record" use="Section" />
<xsl:template match="/Records">
<Configuration>
<xsl:for-each select="record[count(. | key('domain-name', Domain)[1]) = 1]">
<xsl:sort select="Domain" />
<Domain name="{Domain}">
<xsl:for-each select="record[count(. | key('section-name', Section)[1]) = 1]">
<xsl:sort select="Section" />
<Section name="{Section}">
<Option keyword="{Keyword/text()}">
<Control type="{Control/text()}"/>
</Option>
</Section>
</xsl:for-each>
</Domain>
</xsl:for-each>
</Configuration>
</xsl:template>
Is giving me 给我
<Configuration>
<Domain name="Domain 1" />
<Domain name="Domain 2" />
</Configuration>
For your inner grouping, you are grouping Section
elements within Domain
, so both elements need to be within the key 对于内部分组,您是将
Domain
元素中的Section
元素分组,因此两个元素都必须在键中
<xsl:key name="section-name" match="record" use="concat(Domain, '|', Section)" />
The inner xsl:for-each
then needs to be changed to use they new key format. 然后需要更改内部的
xsl:for-each
以使用新的密钥格式。 But also because you are doing xsl:for-each select="group...."
which won't work because you are currently positioned on a record
and so the inner xsl:for-each
is looking for a child element also called record
. 而且还因为您正在执行
xsl:for-each select="group...."
,该操作将不起作用,因为您当前位于record
,因此内部xsl:for-each
正在寻找一个子元素,该元素也称为record
。 It should look like this, which only consider record
elements for the current Domain
value 它看起来应该像这样,它只考虑当前
Domain
值的record
元素
<xsl:for-each select="key('domain-name', Domain)[count(. | key('section-name', concat(Domain, '|', Section))[1]) = 1]">
Try this XSLT 试试这个XSLT
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output method="xml" indent="yes" />
<xsl:key name="domain-name" match="record" use="Domain" />
<xsl:key name="section-name" match="record" use="concat(Domain, '|', Section)" />
<xsl:template match="/Records">
<Configuration>
<xsl:for-each select="record[count(. | key('domain-name', Domain)[1]) = 1]">
<xsl:sort select="Domain" />
<Domain name="{Domain}">
<xsl:for-each select="key('domain-name', Domain)[count(. | key('section-name', concat(Domain, '|', Section))[1]) = 1]">
<xsl:sort select="Section" />
<Section name="{Section}">
<Option keyword="{Keyword/text()}">
<Control type="{Control/text()}"/>
</Option>
</Section>
</xsl:for-each>
</Domain>
</xsl:for-each>
</Configuration>
</xsl:template>
</xsl:stylesheet>
It looks like you also then need a third level of grouping, on Keyword
, but you should be able to work that out now (you will need the key to consider Domain
, Section
and Keyword
) 看来您还需要在
Keyword
上进行第三级分组,但是您现在应该可以解决这个问题(您需要使用Key来考虑Domain
, Section
和Keyword
)
