[英]Copying tag values from one XML to another using XSLT
I have two xml files, say file1.xml which is as follows: 我有两个xml文件,比如file1.xml ,如下所示:
<?xml version="1.0"?>
<root >
<text id='a'>This is to be replaced</text>
<note>This should not be touched</note>
<text id='b'>This is intact</text>
</root>
file2.xml is as follows file2.xml如下
<?xml version="1.0"?>
<root >
<text id='a'>Replacement Text</text>
<note>This is a personal note</note>
</root>
I expect an output xml file of the form : 我期望输出xml文件的形式:
output.xml 与Output.xml
<?xml version="1.0"?>
<root>
<text id='a'>Replacement Text</text>
<note>This should not be touched</note>
<text id='b'>This is intact</text>
</root>
Please help me with a xsl to get the desired output. 请帮我用xsl来获得所需的输出。 This is not a homework and I am trying to understand xslt. 这不是作业,我试图理解xslt。
If you don't know your XSLT processor version, then run this transform and report the results... 如果您不知道自己的XSLT处理器版本,请运行此转换并报告结果...
<xsl:stylesheet version = "1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:msxsl="urn:schemas-microsoft-com:xslt">
<xsl:output method = "text" />
<xsl:template match = "/" >
<xsl:text>Version : </xsl:text><xsl:value-of select = "system-property('xsl:version')" /><xsl:text >
</xsl:text>
<xsl:text>Vendor : </xsl:text><xsl:value-of select = "system-property('xsl:vendor')" /><xsl:text >
</xsl:text>
<xsl:text>URL : </xsl:text><xsl:value-of select = "system-property('xsl:vendor-url')" /><xsl:text >
</xsl:text>
<xsl:text>MS ver : </xsl:text><xsl:value-of select = "system-property('msxsl:version')" /><xsl:text >
</xsl:text>
</xsl:template>
</xsl:stylesheet>
This is not tested, but it should work... 这没有经过测试,但应该有效......
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes" omit-xml-declaration="yes" />
<xsl:strip-space elements="*" />
<xsl:param name="url-of-file2" />
<xsl:variable name="file2" select="document($url-of-file2)" />
<xsl:template match="@*|node()" name="ident">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="*[@id]">
<xsl:variable name="ele" select="name()" />
<xsl:variable name="id" select="@id" />
<xsl:variable name="replacement-node" select="($file2//*[name()=$ele][@id=$id])[1]" />
<xsl:choose>
<xsl:when test="$replacement-node">
<xsl:copy>
<xsl:apply-templates select="@*"/>
<xsl:copy-of select="$replacement-node/text()"/>
<xsl:apply-templates select="*|comment()|processing-instruction()"/>
</xsl:copy>
</xsl:when>
<xsl:otherwise><xsl:call-template name="ident" /></xsl:otherwise>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>
This transformation : 这种转变 :
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output omit-xml-declaration="yes" indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:variable name="vReps" select="document('file:///c:/temp/delete/file2.xml')/*/*[1]"/>
<xsl:template match="node()|@*">
<xsl:copy>
<xsl:apply-templates select="node()|@*"/>
</xsl:copy>
</xsl:template>
<xsl:template match="text[@id='a']/text()">
<xsl:value-of select="$vReps"/>
</xsl:template>
</xsl:stylesheet>
when applied on this XML document (the provided file1.xml): 当应用于此XML文档 (提供的file1.xml)时:
<root>
<text id='a'>This is to be replaced</text>
<note>This should not be touched</note>
<text id='b'>This is intact</text>
</root>
and having the provided file2.xml residing in c:\\temp\\delete\\file2.xml
: 并且提供的file2.xml位于c:\\temp\\delete\\file2.xml
:
<root>
<text id='a'>Replacement Text</text>
<note>This is a personal note</note>
</root>
produces the wanted, correct result: 产生想要的,正确的结果:
<root>
<text id="a">Replacement Text</text>
<note>This should not be touched</note>
<text id="b">This is intact</text>
</root>
Explanation : 说明 :
Use and overriding of the identity rule . 使用和覆盖标识规则 。
Use of the standard XSLT function document()
. 使用标准的XSLT函数document()
