XSLT 连接重复元素的不同值 [英] XSLT to concate distinct values for repeated elements
本文介绍了XSLT 连接重复元素的不同值的处理方法,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
我有一个要求,我将按如下方式获取 XML:
I have a requirement where i will be getting the XML as follows:
<Input>
<Record>
<EMPID>FirstEmployee</EMPID>
</Record>
<Record>
<EMPID>SecondEmployee</EMPID>
</Record>
<Record>
<EMPID>FirstEmployee</EMPID>
</Record>
<Record>
<EMPID>SecondEmployee</EMPID>
</Record>
</Input>
应用转换后我对上述 xml 的预期输出是:
My expected output for the xml above after applying transformation is:
<Output>
<Record>
<EMPID>FirstEmployee|1</EMPID>
</Record>
<Record>
<EMPID>SecondEmployee|1</EMPID>
</Record>
<Record>
<EMPID>FirstEmployee|2</EMPID>
</Record>
<Record>
<EMPID>SecondEmployee|2</EMPID>
</Record>
</Output>
当以这种方式使用其中一种解决方案时

谁能帮忙解决这个问题
推荐答案
这是一个使用 的选项xsl:number...
XML 输入
<Input>
<Record>
<EMPID>FirstEmployee</EMPID>
</Record>
<Record>
<EMPID>SecondEmployee</EMPID>
</Record>
<Record>
<EMPID>FirstEmployee</EMPID>
</Record>
<Record>
<EMPID>SecondEmployee</EMPID>
</Record>
</Input>
XSLT 1.0
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:template match="@*|node()">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="/Input">
<Output>
<xsl:apply-templates/>
</Output>
</xsl:template>
<xsl:template match="EMPID">
<xsl:variable name="current" select="."/>
<xsl:variable name="pos">
<xsl:number level="any" count="EMPID[.=$current]"/>
</xsl:variable>
<xsl:copy>
<xsl:value-of select="concat(.,'|',$pos)"/>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
XML 输出
<Output>
<Record>
<EMPID>FirstEmployee|1</EMPID>
</Record>
<Record>
<EMPID>SecondEmployee|1</EMPID>
</Record>
<Record>
<EMPID>FirstEmployee|2</EMPID>
</Record>
<Record>
<EMPID>SecondEmployee|2</EMPID>
</Record>
</Output>

编辑更新的问题...
您的 xsl:for-each
正在选择 client:Record
,因此您需要更新 current
变量以选择子 客户端:EMPID
.您还应该计算 client:Record
元素而不是 client:EMPID
.
Your xsl:for-each
is selecting client:Record
, so you need to update the current
variable to select the child client:EMPID
. You should also count the client:Record
elements instead of client:EMPID
.
示例
<xsl:template match="/">
<client:Output>
<xsl:for-each select="client:Input/client:Record">
<client:Record>
<xsl:variable name="current" select="client:EMPID"/>
<xsl:variable name="pos">
<xsl:number level="any" count="client:Record[client:EMPID=$current]"/>
</xsl:variable>
<client:EMPID>
<xsl:value-of select='concat(.,"|",$pos)'/>
</client:EMPID>
</client:Record>
</xsl:for-each>
</client:Output>
</xsl:template>
