I want to use templates to reverse the different sequences of XML; For example :
<book title="Definitive XML Schema">
<author first="Priscilla" />
<chapter title="[I] ">
<section title="[I.1]" />
<section title="[I.2]">
<section title="[I.2.1]" />
<section title="[I.2.2]" />
</section>
<section title="[I.3] ">
<section title="[I.3.1]" />
</section>
</chapter>
<chapt开发者_运维知识库er title="[II]">
<section title="[II.1]" />
<section title="[II.2]">
<section title="[II.2.1]" />
<section title="[II.2.2]" />
</section>
</chapter>
</book>
I want to get the output like this:this is my xsl.
<?xml version="1.0" encoding="UTF-8"?>
<book title="Definitive XML Schema">
<author first="Priscilla"/>
<chapter title="[I]">
<section title="[I.3]">
<section title="[I.3.1]"/>
</section>
<section title="[I.2]">
<section title="[I.2.2]"/>
<section title="[I.2.1]"/>
</section>
<section title="[I.1]"/>
</chapter>
<chapter title="[II]">
<section title="[II.2]">
<section title="[II.2.2]"/>
<section title="[II.2.1]"/>
</section>
<section title="[II.1]"/>
</chapter>
</book>
Yes,the sections have been reversed but the chapters are not.
I try to use two templates to solve it,but it can not work..
<?xml version="1.0" encoding="UTF-8"?>
<xsl:transform version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema" exclude-result-prefixes="xs">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent ="yes"/>
<xsl:template match="/">
<xsl:apply-templates/>
<xsl:text> </xsl:text>
</xsl:template>
<xsl:template match="book">
<xsl:copy>
<xsl:sequence select="@title"/>
<xsl:sequence select="author"/>
<xsl:apply-templates select="chapter">
<xsl:with-param name="seq" select="section"/>
</xsl:apply-templates>
</xsl:copy>
</xsl:template>
<xsl:template match ="chapter|section" as="element()">
<xsl:param name="seq" as="element(section)*"/>
<xsl:copy>
<xsl:sequence select="@title"/>
<xsl:if test="not(empty($seq))">
<xsl:apply-templates select="chapter">
<xsl:with-param name="seq" select="$seq[position()>1]"/>
</xsl:apply-templates>
<xsl:apply-templates select="$seq[1]"/>
</xsl:if>
</xsl:copy>
</xsl:template>
</xsl:transform>
Here is a simpler XSLT 1.0 (and 2.0) solution:
<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:template match="node()|@*">
<xsl:copy>
<xsl:apply-templates select="node()|@*"/>
</xsl:copy>
</xsl:template>
<xsl:template match="*[section]">
<xsl:copy>
<xsl:copy-of select="@*"/>
<xsl:apply-templates>
<xsl:sort select="position()"
data-type="number" order="descending"/>
</xsl:apply-templates>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
when this transformation is applied on the following XML document:
<book title="Definitive XML Schema">
<author first="Priscilla" />
<chapter title="[I] ">
<section title="[I.1]" />
<section title="[I.2]">
<section title="[I.2.1]" />
<section title="[I.2.2]" />
</section>
<section title="[I.3] ">
<section title="[I.3.1]" />
</section>
</chapter>
<chapter title="[II]">
<section title="[II.1]" />
<section title="[II.2]">
<section title="[II.2.1]" />
<section title="[II.2.2]" />
</section>
</chapter>
</book>
the wanted, correct result (all sequences of section
elements reversed) is produced :
<book title="Definitive XML Schema">
<author first="Priscilla"/>
<chapter title="[I] ">
<section title="[I.3] ">
<section title="[I.3.1]"/>
</section>
<section title="[I.2]">
<section title="[I.2.2]"/>
<section title="[I.2.1]"/>
</section>
<section title="[I.1]"/>
</chapter>
<chapter title="[II]">
<section title="[II.2]">
<section title="[II.2.2]"/>
<section title="[II.2.1]"/>
</section>
<section title="[II.1]"/>
</chapter>
</book>
This XSLT 2.0 stylesheet:
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:strip-space elements="*"/>
<xsl:template match="node()|@*" name="identity">
<xsl:copy>
<xsl:apply-templates select="node()|@*"/>
</xsl:copy>
</xsl:template>
<xsl:template match="chapter|section">
<xsl:copy>
<xsl:apply-templates select="@*"/>
<xsl:apply-templates>
<xsl:sort select="tokenize(@title,'.')[last()]"
order="descending"
data-type="number"/>
</xsl:apply-templates>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
Output:
<book title="Definitive XML Schema">
<author first="Priscilla"/>
<chapter title="[I] ">
<section title="[I.3] ">
<section title="[I.3.1]"/></section>
<section title="[I.2]">
<section title="[I.2.2]"/>
<section title="[I.2.1]"/></section>
<section title="[I.1]"/>
</chapter>
<chapter title="[II]">
<section title="[II.2]">
<section title="[II.2.2]"/>
<section title="[II.2.1]"/></section>
<section title="[II.1]"/>
</chapter>
</book>
