问题描述
您好,我正在尝试在 pdf 文件中创建分组我必须在另一个分组中使用分组.例如按日期分组,然后按名称分组,然后按城市...
Hello I'm trying to create grouping in the pdf file and I have to use grouping inside another grouping. f.e. group by date, then group by name, then by city...
xml:
<record>
<name>Palace1</name>
<info>
<date>2012-01-01</date>
<city>Random1</city>
</info>
<info>
<date>2012-01-01</date>
<city>SuperRandom</city>
</info>
<info>
<date>2012-01-02</date>
<city>Random22</city>
</info>
...
</record>
<record>
<name>Palace2</name>
<info>
<date>2012-01-01</date>
<city>Random99</city>
</info>
<info>
<date>2012-01-02</date>
<city>Random1</city>
</info>
...
</record>
...
假设我们需要按 2012-01-01 到 2012-01-01 的日期对记录进行分组,然后按名称分组
So lets say we need to group our records by date from 2012-01-01 to 2012-01-01 and the group them by name
日期 2012-01-01
Place1
随机 1
超级随机
Palace2
Random99
日期 2012-01-02
Palace1
Random22
Palace2
随机 1
所以我正在使用
<xsl:for-each-group select="dt:record" group-by="dt:info/dt:date">
<xsl:sort select="dt:date" order="ascending"/>
<fo:block font-weight="bold"> Date: <xsl:value-of select="format-dateTime(dt:date,'[Y0001].[M01].[D01]','en',(),'lt')"/></fo:block>
<xsl:for-each select="current-group()"> //here im guessing we should put another for- each-group
<xsl:for-each-group select="parent::dt:info/dt:record" group-by="dt:name">
<fo:block>Place1 <xsl:value-of select="dt:name"><fo:block>
<xsl:for-each select="current-group()">
<fo:block> <xsl:value-of select="dt:info/dt:city"></fo:block>
</xsl:for-each>
</xsl:for-each-group>
</xsl:for-each>
</xsl:for-each-group>
但这不起作用......出于某种原因,我得到了更多的记录名称
but this doesn't work... for some reason I get way more record names then I should
推荐答案
这里是如何进行这样的分组:
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xsl:output omit-xml-declaration="yes" indent="yes"/>
<xsl:template match="/*">
<xsl:for-each-group select="*/info" group-by="date">
<xsl:sort select="date"/>
Date: <xsl:value-of select="date"/>
<xsl:for-each-group select="current-group()" group-by="../name">
<xsl:value-of select="concat('
 ',../name)"/>
<xsl:for-each-group select="current-group()" group-by="city">
<xsl:value-of select="concat('
 ', city)"/>
</xsl:for-each-group>
</xsl:for-each-group>
</xsl:for-each-group>
</xsl:template>
</xsl:stylesheet>
当此转换应用于从非格式良好的提供的 XML 派生的格式良好的 XML 文档时:
<t>
<record>
<name>Palace1</name>
<info>
<date>2012-01-01</date>
<city>Random1</city>
</info>
<info>
<date>2012-01-01</date>
<city>SuperRandom</city>
</info>
<info>
<date>2012-01-02</date>
<city>Random22</city>
</info> ...
</record>
<record>
<name>Palace2</name>
<info>
<date>2012-01-01</date>
<city>Random99</city>
</info>
<info>
<date>2012-01-02</date>
<city>Random1</city>
</info> ...
</record>
</t>
产生了想要的、正确分组的结果:
Date: 2012-01-01
Palace1
Random1
SuperRandom
Palace2
Random99
Date: 2012-01-02
Palace1
Random22
Palace2
Random1
