问题
I have the following input XML:
<root>
<aaa>some string aaa</aaa>
<bbb>some string bbb</bbb>
<ddd>some string ddd</ddd>
</root>
Using XSLT I want to the following output:
<root>
<aaa>some string aaa</aaa>
<bbb>some string bbb</bbb>
<ccc>some string ccc</ccc>
<ddd>some string ddd</ddd>
</root>
My XSLT is:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="3.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="@*|node()">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="root">
<root>
<ccc>some string ccc</ccc>
<xsl:apply-templates select="@*|node()"/>
</root>
</xsl:template>
</xsl:stylesheet>
But I'm not getting my desired output. How could I put the ccc
element between bbb
and ddd
elements using the identity template?
I can use XSLT 3.0 if that helps.
回答1:
Kenneth's answer is fine but as the question is tagged as XSLT 3.0 it can be written more compact so I add this answer as an alternative
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="3.0">
<xsl:output indent="yes"/>
<xsl:mode on-no-match="shallow-copy"/>
<xsl:template match="ddd">
<ccc>some string ccc</ccc>
<xsl:next-match/>
</xsl:template>
</xsl:stylesheet>
using <xsl:mode on-no-match="shallow-copy"/>
to express the identity transformation and using <xsl:next-match/>
to delegate copying of the ddd
element to it.
回答2:
Use the identity transformation with a second template that matches the element before or after the insertion point, and then insert the new element after or before copying over the matched element. To wit:
Given this input XML,
<root>
<aaa>some string aaa</aaa>
<bbb>some string bbb</bbb>
<ddd>some string ddd</ddd>
</root>
this XSLT,
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes"/>
<xsl:template match="@*|node()">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="ddd">
<ccc>some string ccc</ccc>
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
will generate this output XML:
<?xml version="1.0" encoding="UTF-8"?>
<root>
<aaa>some string aaa</aaa>
<bbb>some string bbb</bbb>
<ccc>some string ccc</ccc>
<ddd>some string ddd</ddd>
</root>
