2010-10-29 06:51:21
Hi, Martin

Below are the inputs. I need to generate sequential ID for all the sect element including any nesting element sec/sec/sec for sec2 sec 3 sec4

XML
====
<?xml version="1.0" encoding="UTF-8"?>
<body>
   <sect>
       <title>Section Head1</title>
       <para>Paragraph text</para>
<para>Element para or some other any element and any no.of element may come here</para>
   <sect>
       <title>Section Head2</title>
       <para>Paragraph text</para>
   </sect>
   </sect>
<para>Element para or some other any element and any no.of element may come here</para>
   <sect>
       <title>Section Head3</title>
       <para>Paragraph text</para>
   </sect>
</body>

XSLT
=====
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; version="2.0"> <xsl:output method="xml" encoding="us-ascii" indent="no" omit-xml-declaration="no" include-content-type="no" />
   <xsl:template match="body">
       <article><xsl:apply-templates/></article>
   </xsl:template>
   <xsl:template match="sect">
       <xsl:variable name="pos"><xsl:number/></xsl:variable>
       <xsl:choose>
<xsl:when test="ancestor-or-self::body/sect"><sec1 id="sec{$pos}"><xsl:apply-templates/></sec1></xsl:when> <xsl:when test="ancestor-or-self::body/sect/sect"><sec2 id="sec{$pos}"><xsl:apply-templates/></sec2></xsl:when> <xsl:when test="ancestor-or-self::body/sect/sect/sect"><sec3 id="sec{$pos}"><xsl:apply-templates/></sec3></xsl:when> <xsl:when test="ancestor-or-self::body/sect/sect/sect/sect"><sec4 id="sec{$pos}"><xsl:apply-templates/></sec4></xsl:when> </xsl:choose> </xsl:template> <xsl:template match="sect/title"><title><xsl:apply-templates/></title></xsl:template> <xsl:template match="para"><p><xsl:apply-templates/></p></xsl:template> </xsl:stylesheet>

Current Output
===========
<?xml version="1.0" encoding="us-ascii"?>
   <sec1 id="sec1">
       <title>Section Head1</title>
       <p>Paragraph text</p>
<p>Element para or some other any element and any no.of element may come here</p>
   <sec1 id="sec1">
       <title>Section Head2</title>
       <p>Paragraph text</p>
   </sec1>
   </sec1>
<p>Element para or some other any element and any no.of element may come here</p>
   <sec1 id="sec2">
       <title>Section Head3</title>
       <p>Paragraph text</p>
   </sec1>

Expected:
=======
<?xml version="1.0" encoding="us-ascii"?>
   <sec1 id="sec1">
       <title>Section Head1</title>
       <p>Paragraph text</p>
<p>Element para or some other any element and any no.of element may come here</p>
   <sec2 id="sec2">
       <title>Section Head2</title>
       <p>Paragraph text</p>
   </sec2>
   </sec1>
<p>Element para or some other any element and any no.of element may come here</p>
   <sec1 id="sec3">
       <title>Section Head3</title>
       <p>Paragraph text</p>
   </sec1>
