 Andrew
I amended your xml for better readability and control of the result after
transformation.
<?xml version="1.0" encoding="UTF-8?>
<Root>
<head head-level="1">head title A1</head>
<p>paragraph of A1</p>
<head head-level="2">sub-head title A1.1</head>
<p>paragraph of A1.1</p>
<head head-level="2">sub-head title A1.2</head>
<p>paragraph of A1.2</p>
<head head-level="3">sub-sub-head title A1.2.1</head>
<p>paragraph of A1.2.1</p>
<head head-level="3">sub-sub-head title A1.2.2</head>
<p>paragraph of A1.2.2</p>
<head head-level="1">head title B1</head>
<p>paragraph of B1</p>
</Root>
A similar question has been answered, please see ' flat XML to normal
XML' in this list.
If you know the highest value for @head-level, the xslt is straight forward.
Note, that the <xsl:apply-template
select="followin-sibling::head[1][@head-level='3']"/>
in the last template of the stylesheet is placed *after* the </level>
because head elements with @head-level='3' must not be nested.
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<!-- Created:2005-06-07 Author:rudolf.weinmann@xxxxxxxxxxxx
http://www.assentis.com -->
<xsl:output method="xml" encoding="UTF-8" indent="yes"/>
<xsl:template match="/">
<NewDataSet>
<!-- select all top level head elements -->
<xsl:apply-templates select="Root/head[@head-level='1']"/>
</NewDataSet>
</xsl:template>
<xsl:template match="head[@head-level='1']">
<level>
<title>
<xsl:value-of select="."/>
</title>
<xsl:copy-of select="following-sibling::p[1]"/>
<!-- select all adjaicent head elements with the next higher @head-level
-->
<xsl:apply-templates select="following-sibling::head[@head-level='2']"/>
</level>
</xsl:template>
<xsl:template match="head[@head-level='2']">
<level>
<title>
<xsl:value-of select="."/>
</title>
<xsl:copy-of select="following-sibling::p[1]"/>
<!-- select the adjaicent head element, if it is the next higher @head-level
-->
<xsl:apply-templates select="following-sibling::head[1][@head-level='3']"/>
</level>
</xsl:template>
<xsl:template match="head[@head-level='3']">
<level>
<title>
<xsl:value-of select="."/>
</title>
<xsl:copy-of select="following-sibling::p[1]"/>
</level>
<!-- select the adjaicent head element, if it is the next higher @head-level
-->
<!-- this apply-templates is *after* </level>, because @head-level='3'
elements must not be nested -->
<xsl:apply-templates select="following-sibling::head[1][@head-level='3']"/>
</xsl:template>
</xsl:stylesheet>
And the result:
<?xml version='1.0' encoding='UTF-8' ?>
<NewDataSet>
<level>
<title>head title A1</title>
<p>paragraph of A1</p>
<level>
<title>sub-head title A1.1</title>
<p>paragraph of A1.1</p>
</level>
<level>
<title>sub-head title A1.2</title>
<p>paragraph of A1.2</p>
<level>
<title>sub-sub-head title A1.2.1</title>
<p>paragraph of A1.2.1</p>
</level>
<level>
<title>sub-sub-head title A1.2.2</title>
<p>paragraph of A1.2.2</p>
</level>
</level>
</level>
<level>
<title>head title B1</title>
<p>paragraph of B1</p>
</level>
</NewDataSet>
Hope this helps,
Rudolf
