How can I use XSLT to permutate a node hierarchy? -

-

first of all: i'm total beginner xslt. in project synthesizing tree transformations in more abstract manner. proof of concept trying extend domain simple xslt.

but let's @ 1 example, have several leaves in xml document, in here:

<input>        <a>          <b>            <c>foo </c>            <c>bar </c>          </b>        </a>        <x>          <y>            <z>foobar </z>          </y>        </x> </input>

for want do, it's easier @ paths. a/b/c/foo, a/b/c/bar, /x/y/z/foobar

what want change hierarchy based on index in path. example want first have in order: third level, first level, second level. paths mentioned above: c/a/b/foo, /c/a/b/bar, /z/x/y/foobar.

my approach looked this:

<xsl:template name="leaf">   <xsl:copy>         <!-- copy attributes-->                                            <xsl:copy-of select="@*" />                                           <!-- take level-->         <xsl:copy select="../"/>     </xsl:copy>                      </xsl:template>

but apparently when i'm in <copy> cannot use "../" anymore parent element. i'm looking solution kind of transformations. either using different (my perspective on xslt narrow) or tweaking approach.

desired output:

<output>     <c>         <a>             <b>bar</b>         </a>     </c>     <c>         <a>             <b>foo</b>         </a>     </c>     <z>         <x>             <y>foobar</y>         <x>     <z>     </output>

additional information

  • the input xml has depth 3 (counted without )

second example

<input>     <one>         <two>             <three>                 bla             </three>         </two>         <two>             <three>                 blub             </three>         </two>     </one> </input>  <output>     <three>         <one>             <second>bla</second>         </one>         <one>             <second>blub</second>         </one>     </three> </output>

i'm still not sure if made clear transformation want achieve. maybe idea help: imagine totally decompose input xml: every leaf consider leaf , path leaf , transform path according rule (third, first, second).

this not elegant approach, works:

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:strip-space elements="*"/>  <xsl:template match="/input">     <output>         <xsl:apply-templates select="*/*/*/text()"/>     </output> </xsl:template>  <xsl:template match="text()">     <xsl:element name="{name(ancestor::*[1])}">         <xsl:element name="{name(ancestor::*[3])}">             <xsl:element name="{name(ancestor::*[2])}">                 <xsl:copy-of select="."/>             </xsl:element>         </xsl:element>     </xsl:element> </xsl:template>  </xsl:stylesheet>
