使用XSLT对XML进行分组 [英] Grouping XML using XSLT

问题描述

我有以下XML

I have the following XML

  <?xml version="1.0" encoding="UTF-8" ?> 
- <Detail>
	- <Books>
		- <Book_Group>
		  60 
		  <Book_NM>Funda's of Prof Ethics</Book_NM> 
		  <PROMPT_ORD_NO>12</PROMPT_ORD_NO> 
		</Book_Group>
	</Books>
	- <Books>
		- <Book_Group>
		  60 
		  <Book_NM>Decision Making Capabilities</Book_NM> 
		  <Book_ORD_NO>17</Book_ORD_NO> 
		</Book_Group>
	</Books>
	- <Books>
		- <Book_Group>
		  70 
		  <Book_NM>OOPS Concepts</Book_NM> 
		  <Book_ORD_NO>11</Book_ORD_NO> 
		</Book_Group>
	</Books>
	<Books>
	- 	<Book_Group>
		  70 
		  <Book_NM>Power Electronics</Book_NM> 
		  <Book_ORD_NO>13</Book_ORD_NO> 
		</Book_Group>
	</Books>
  </Detail>

使用XSLT，我需要有一个XML，其唯一的Book_Group作为根元素，而与该Book_Group对应的所有子元素作为子元素，如下所示:

Using XSLT I need to have an XML with unique Book_Group as a root element and all the child elements corresponding to that Book_Group as child elements as Shown below:

<Detail>
	- <Books>
		- <Book_Group>
		  60 
		  <Book_NM>Funda's of Prof Ethics</Book_NM> 
		  <PROMPT_ORD_NO>12</PROMPT_ORD_NO> 
		  <Book_NM>Decision Making Capabilities</Book_NM> 
		  <Book_ORD_NO>17</Book_ORD_NO> 
		</Book_Group>
	</Books>
	- <Books>
		- <Book_Group>
		  70 
		  <Book_NM>OOPS Concepts</Book_NM> 
		  <Book_ORD_NO>11</Book_ORD_NO> 
		  <Book_NM>Power Electronics</Book_NM> 
		  <Book_ORD_NO>13</Book_ORD_NO> 
		</Book_Group>
	</Books>
</Detail>

请为我提供XSLT以实现结果...使用< xsl:for-each xmlns:xsl =#unknown">我无法完全做到这一点.

Kindly provide me with XSLT to achieve the result...Using <xsl:for-each xmlns:xsl="#unknown"> I m not able to do this completely

推荐答案

在w3cschool网站上查看此示例.

http://www.w3schools.com/xsl/tryxslt.asp?xmlfile=cdcatalog& xsltfile = cdcatalog [^ ]

如果您将第一个title元素的内容更改为Book_Group的内容，将会发现这将非常困难.

Check out this example on the w3cschool website.

http://www.w3schools.com/xsl/tryxslt.asp?xmlfile=cdcatalog&xsltfile=cdcatalog[^]

If you would change the content of the first title element with that of a Book_Group you''ll see that it is going to be very difficult.

<title>60
<Book_NM>Funda's of Prof Ethics</Book_NM><PROMPT_ORD_NO>12</PROMPT_ORD_NO>
</title>

结果中显示的标题是" Ethics12教授的60个Funda's "，这意味着无法进行分组，因为您将无法获得唯一的分组价值.

祝你好运！

The title shown in the result is "60 Funda''s of Prof Ethics12" meaning that grouping is not possible because you won''t get an unique value for grouping them.

Good luck!
