我有以下输入xml:
<?xml version="1.0" encoding="UTF-8"?>
<response>
<case>
<CMEDIA>Phone</CMEDIA>
</case>
<results>
<row>
<IKEY>TestKey1</IKEY>
<OBJECTID>TestObject1</OBJECTID>
<OBJECTPHYFILEID>ObjPhyField1</OBJECTPHYFILEID>
</row>
<row>
<IKEY>TestKey1</IKEY>
<OBJECTID>TestObject2</OBJECTID>
<OBJECTPHYFILEID>ObjPhyField2</OBJECTPHYFILEID>
</row>
<row>
<IKEY>TestKey1</IKEY>
<OBJECTID>TestObject3</OBJECTID>
<OBJECTPHYFILEID>ObjPhyField3</OBJECTPHYFILEID>
</row>
<row>
<IKEY>TestKey4</IKEY>
<OBJECTID>TestObject4</OBJECTID>
<OBJECTPHYFILEID>ObjPhyField4</OBJECTPHYFILEID>
</row>
</results>
</response>
我的要求是将所有匹配的<IKEY>
行&amp;将它们移到一个<row>
下并移动<OBJECTID>
&amp; <OBJECTPHYFILEID>
节点存在于新节点<IKEY>
下的匹配<SourceInstance>
行(即同一行)中。最终我的输出xml应如下所示:
<?xml version="1.0" encoding="UTF-8"?>
<response>
<case>
<CMEDIA>Phone</CMEDIA>
</case>
<results>
<row>
<IKEY>TestKey1</IKEY>
<Sources>
<SourceInstance>
<OBJECTID>TestObject1</OBJECTID>
<OBJECTPHYFILEID>ObjPhyField1</OBJECTPHYFILEID>
</SourceInstance>
<SourceInstance>
<OBJECTID>TestObject2</OBJECTID>
<OBJECTPHYFILEID>ObjPhyField2</OBJECTPHYFILEID>
</SourceInstance>
<SourceInstance>
<OBJECTID>TestObject3</OBJECTID>
<OBJECTPHYFILEID>ObjPhyField3</OBJECTPHYFILEID>
</SourceInstance>
</Sources>
</row>
<row>
<IKEY>TestKey4</IKEY>
<Sources>
<SourceInstance>
<OBJECTID>TestObject4</OBJECTID>
<OBJECTPHYFILEID>ObjPhyField4</OBJECTPHYFILEID>
</SourceInstance>
</Sources>
</row>
</results>
</response>
我正在尝试使用以下XSLT,但无法实现所需的xml:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output method="xml" indent="yes" />
<xsl:key name="ikey" match="row" use="string(IKEY)" />
<xsl:template match="results">
<xsl:copy>
<xsl:apply-templates select="row[generate-id() = generate-id(key('ikey', string(IKEY))[1])]" mode="ikey" />
</xsl:copy>
</xsl:template>
<xsl:template match="row" mode="ikey">
<xsl:choose>
<xsl:when test="IKEY">
<row>
<IKEY>
<xsl:value-of select="//IKEY" />
</IKEY>
<Sources>
<xsl:for-each select="OBJECTID">
<SourceInstance>
<xsl:value-of select="//key('ikey', IKEY)/OBJECTID" />
</SourceInstance>
</xsl:for-each>
</Sources>
</row>
</xsl:when>
</xsl:choose>
</xsl:template>
<xsl:template match="@*|node()">
<xsl:copy>
<xsl:apply-templates select="@*|node()" />
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
我确信我在这里遗漏了一些东西。有人可以帮帮我吗?
答案 0 :(得分:1)
使用<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output method="xml" indent="yes" />
<xsl:key name="ikey" match="row" use="string(IKEY)" />
<xsl:template match="results">
<xsl:copy>
<xsl:apply-templates select="row[generate-id() = generate-id(key('ikey', string(IKEY))[1])]" mode="ikey" />
</xsl:copy>
</xsl:template>
<xsl:template match="row" mode="ikey">
<xsl:choose>
<xsl:when test="IKEY">
<row>
<xsl:copy-of select="IKEY"/>
<Sources>
<xsl:apply-templates select="key('ikey', IKEY)"/>
</Sources>
</row>
</xsl:when>
</xsl:choose>
</xsl:template>
<xsl:template match="@*|node()">
<xsl:copy>
<xsl:apply-templates select="@*|node()" />
</xsl:copy>
</xsl:template>
<xsl:template match="row">
<SourceInstance>
<xsl:apply-templates select="*[not(self::IKEY)]"/>
</SourceInstance>
</xsl:template>
</xsl:stylesheet>
