XSLT对每4个相邻元素进行分组 [英] XSLT grouping every 4 adjacent elements
本文介绍了XSLT对每4个相邻元素进行分组的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我有一个如下所示的xml.
I have a xml like below.
源XML:
<?xml version="1.0" encoding="Windows-1252"?>
<XML>
<Attributes>
<Attribute>
<Name>Collection</Name>
<Value />
</Attribute>
<Attribute>
<Name>A</Name>
<Value>Testing</Value>
</Attribute>
<Attribute>
<Name>B</Name>
<Value>Blank</Value>
</Attribute>
<Attribute>
<Name>C</Name>
<Value>11</Value>
</Attribute>
<Attribute>
<Name>D</Name>
<Value>NA</Value>
</Attribute>
<Attribute>
<Name>A</Name>
<Value>Testing1</Value>
</Attribute>
<Attribute>
<Name>B</Name>
<Value>Red</Value>
</Attribute>
<Attribute>
<Name>C</Name>
<Value>12</Value>
</Attribute>
<Attribute>
<Name>D</Name>
<Value>NAT</Value>
</Attribute>
</Attributes>
</XML>
从上面的xml中,我该怎么做.我只想将它们分为4组.因此,在源xml中的前4个元素中,/attribute/Name ='A'-/attribute/Name ='D'将在第一组中.接下来的4个,其中/attribute/Name ='A'-/attribute/Name ='D'将在第二个组中....如下所示
From the above xml how I can I do this. I only want to group them in groups of 4. So first 4 (in the source xml) element where /attribute/Name='A' - /attribute/Name='D' will be in the first group. and next 4 where /attribute/Name='A' - /attribute/Name='D' will be in the second group .... like below
预先感谢
输出
<Collection name="Collection" >
<ComplexAttr>
<Attr name="A" value="Testing" />
<Attr name="B" value="Blank" />
<Attr name="C" value="11" />
<Attr name="D" value="NA" />
</ComplexAttr>
<ComplexAttr >
<Attr name="A" value="Testing1" />
<Attr name="B" value="Red" />
<Attr name="C" value="12" />
<Attr name="D" value="NA" />
</ComplexAttr>
</Collection>
推荐答案
这是常见问题解答.请参阅我对您问题的评论中的链接.这是根据您的输入和所需输出量身定制的样式表:
This is a FAQ. See my link in the comments to your question. Here is a stylesheet tailored to your input and desired output:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<!-- the number of items to include in each group -->
<xsl:variable name="group" select="4" />
<xsl:template match="/">
<Collection name="Collection">
<xsl:apply-templates
select="XML/Attributes/Attribute[not(Name='Collection')]
[position() mod $group = 1]" />
</Collection>
</xsl:template>
<xsl:template match="Attribute" mode="inner">
<Attr name="{Name}" value="{Value}" />
</xsl:template>
<xsl:template match="Attribute">
<ComplexAttr>
<xsl:apply-templates
select=".|following-sibling::Attribute[position() < $group]"
mode="inner" />
</ComplexAttr>
</xsl:template>
</xsl:stylesheet>
产生:
<Collection name="Collection">
<ComplexAttr>
<Attr name="A" value="Testing" />
<Attr name="B" value="Blank" />
<Attr name="C" value="11" />
<Attr name="D" value="NA" />
</ComplexAttr>
<ComplexAttr>
<Attr name="A" value="Testing1" />
<Attr name="B" value="Red" />
<Attr name="C" value="12" />
<Attr name="D" value="NAT" />
</ComplexAttr>
</Collection>
