我有一个类似的xml
d
我的xslt,
<DESIGN-FUNCTION-PROTOTYPE>
<SHORT-NAME>xxx</SHORT-NAME>
<TYPE-TREF TYPE="DESIGN-FUNCTION-PROTOTYPE">ABC/DEF/123</TYPE-TREF>
</DESIGN-FUNCTION-PROTOTYPE>
<DESIGN-FUNCTION-PROTOTYPE>
<SHORT-NAME>yyy</SHORT-NAME>
<TYPE-TREF TYPE="DESIGN-FUNCTION-PROTOTYPE">LMN/OPQ/123</TYPE-TREF>
</DESIGN-FUNCTION-PROTOTYPE>
<DESIGN-FUNCTION-PROTOTYPE>
<SHORT-NAME>mmm</SHORT-NAME>
<TYPE-TREF TYPE="DESIGN-FUNCTION-PROTOTYPE">XYZ/GHY/456</TYPE-TREF>
</DESIGN-FUNCTION-PROTOTYPE>
<DESIGN-FUNCTION-PROTOTYPE>
<SHORT-NAME>nnn</SHORT-NAME>
<TYPE-TREF TYPE="DESIGN-FUNCTION-PROTOTYPE">AJK/UTL/456</TYPE-TREF>
</DESIGN-FUNCTION-PROTOTYPE>
我的目的是要迭代所有'DESIGN-FUNCTION-PROTOTYPE'元素并显示'TYPE-TREF'值的子字符串,但是如果已经读取'TYPE-TREF'值的子字符串..i必须跳过该元素。
预期的输出
<xsl:template name="substring-after-last">
<xsl:param name="string" />
<xsl:param name="delimiter" />
<xsl:choose>
<xsl:when test="contains($string, $delimiter)">
<xsl:call-template name="substring-after-last">
<xsl:with-param name="string"
select="substring-after($string, $delimiter)" />
<xsl:with-param name="delimiter" select="$delimiter" />
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$string" />
</xsl:otherwise>
</xsl:choose>
</xsl:template>
<xsl:for-each select="select="//DESIGN-FUNCTION-PROTOTYPE/ea:TYPE-TREF[@TYPE='DESIGN-FUNCTION-TYPE']">
<xsl:variable name="myVar" select="current()"/>
<xsl:variable name="taskName" select="../ea:SHORT-NAME"/>
<xsl:variable name="Var7">
<xsl:call-template name="substring-after-last">
<xsl:with-param name="string" select="$myVar" />
<xsl:with-param name="delimiter" select="'/'" />
</xsl:call-template>
</xsl:variable>
<varoutput>
<xsl:value-of select="$Var7"/>
</varoutput>
</xsl:for-each>
不是,
123
456
通常,我应该只考虑第一次出现的情况,而忽略其余的情况。

假设您使用Xalan,则应该可以使用EXSLT str:split
函数(http://xalan.apache.org/xalan-j/apidocs/org/apache/xalan/lib/ExsltStrings.html#split(java.lang.String,%20java.lang.String):
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:str="http://exslt.org/strings" exclude-result-prefixes="str" version="1.0">
<xsl:key name="group" match="DESIGN-FUNCTION-PROTOTYPE/TYPE-TREF"
use="str:split(., '/')[last()]"/>
<xsl:template match="Root">
<xsl:for-each select="DESIGN-FUNCTION-PROTOTYPE/TYPE-TREF[generate-id() = generate-id(key('group', str:split(., '/')[last()])[1])]">
<varoutput>
<xsl:value-of select="str:split(., '/')[last()]"/>
</varoutput>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
转换
<?xml version="1.0" encoding="UTF-8"?>
<Root>
<DESIGN-FUNCTION-PROTOTYPE>
<SHORT-NAME>xxx</SHORT-NAME>
<TYPE-TREF TYPE="DESIGN-FUNCTION-PROTOTYPE">ABC/DEF/123</TYPE-TREF>
</DESIGN-FUNCTION-PROTOTYPE>
<DESIGN-FUNCTION-PROTOTYPE>
<SHORT-NAME>yyy</SHORT-NAME>
<TYPE-TREF TYPE="DESIGN-FUNCTION-PROTOTYPE">LMN/OPQ/123</TYPE-TREF>
</DESIGN-FUNCTION-PROTOTYPE>
<DESIGN-FUNCTION-PROTOTYPE>
<SHORT-NAME>mmm</SHORT-NAME>
<TYPE-TREF TYPE="DESIGN-FUNCTION-PROTOTYPE">XYZ/GHY/456</TYPE-TREF>
</DESIGN-FUNCTION-PROTOTYPE>
<DESIGN-FUNCTION-PROTOTYPE>
<SHORT-NAME>nnn</SHORT-NAME>
<TYPE-TREF TYPE="DESIGN-FUNCTION-PROTOTYPE">AJK/UTL/456</TYPE-TREF>
</DESIGN-FUNCTION-PROTOTYPE>
</Root>
进入
<?xml version="1.0" encoding="UTF-8"?><varoutput>123</varoutput><varoutput>456</varoutput>
使用Xalan Java和Xalan Java XSLTC。
或者,如注释中所建议,如果您只是想查找不同的值,则可以使用set:distinct
,例如
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:exsl="http://exslt.org/common"
xmlns:str="http://exslt.org/strings"
xmlns:set="http://exslt.org/sets"
exclude-result-prefixes="exsl str set"
version="1.0">
<xsl:template match="Root">
<xsl:variable name="split-values">
<xsl:for-each select="DESIGN-FUNCTION-PROTOTYPE/TYPE-TREF">
<xsl:copy-of select="str:split(., '/')[last()]"/>
</xsl:for-each>
</xsl:variable>
<xsl:copy-of select="set:distinct(exsl:node-set($split-values)/node())"/>
</xsl:template>
</xsl:stylesheet>

要在纯XSLT 1.0中执行此操作,而不依赖于特定于处理器的扩展,您可以执行以下操作:
XSLT 1.0
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:key name="k1" match="DESIGN-FUNCTION-PROTOTYPE" use="substring-after(substring-after(TYPE-TREF, '/'), '/')"/>
<xsl:template match="/Root">
<root>
<xsl:for-each select="DESIGN-FUNCTION-PROTOTYPE[count(. | key('k1', substring-after(substring-after(TYPE-TREF, '/'), '/'))[1]) = 1]">
<varoutput>
<xsl:value-of select="substring-after(substring-after(TYPE-TREF, '/'), '/')" />
</varoutput>
</xsl:for-each>
</root>
</xsl:template>
</xsl:stylesheet>
演示:https://xsltfiddle.liberty-development.net/bFN1y9s
这当然是假设您追求的值始终是TYPE-TREF
中的第三个“令牌”。否则,您将不得不执行与尝试类似的操作:
XSLT 1.0 + EXSLT node-set()函数
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:exsl="http://exslt.org/common"
exclude-result-prefixes="exsl" >
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:key name="k1" match="value" use="."/>
<xsl:template match="/Root">
<!-- EXTRACT VALUES -->
<xsl:variable name="values">
<xsl:for-each select="DESIGN-FUNCTION-PROTOTYPE">
<value>
<xsl:call-template name="last-token">
<xsl:with-param name="text" select="TYPE-TREF"/>
</xsl:call-template>
</value>
</xsl:for-each>
</xsl:variable>
<!-- OUTPUT -->
<root>
<xsl:for-each select="exsl:node-set($values)/value[count(. | key('k1', .)[1]) = 1]">
<varoutput>
<xsl:value-of select="." />
</varoutput>
</xsl:for-each>
</root>
</xsl:template>
<xsl:template name="last-token">
<xsl:param name="text"/>
<xsl:param name="delimiter" select="'/'"/>
<xsl:choose>
<xsl:when test="contains($text, $delimiter)">
<!-- recursive call -->
<xsl:call-template name="last-token">
<xsl:with-param name="text" select="substring-after($text, $delimiter)"/>
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$text"/>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>
