Re: [xsl] Converting siblings to children of a node.

[Mukul Gandhi <mukulw3@xxxxxxxxx>]

Hi Shawn,
  i tried to solve the problem.. Below is the complete
XSL --

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:xalan="http://xml.apache.org/xalan";
exclude-result-prefixes="xalan">
   <xsl:output method="xml" version="1.0"
encoding="UTF-8" indent="yes"/>
   <xsl:template match="longdesc">
   <xsl:for-each select="para">
     <xsl:if test="@style = 'Normal'">
      <p>
	<xsl:value-of select="."/>
      </p>
     </xsl:if>
   <xsl:if test="((@style = 'LS1') and
(preceding-sibling::para[1][@style = 'Normal'])) ">
     <ul>
	<li>
	  <xsl:value-of select="."/>
	</li>
	<xsl:call-template name="printLI">
	   <xsl:with-param name="node_set"
select="xalan:nodeset(following-sibling::para)"/>
	</xsl:call-template>
      </ul>
   </xsl:if>
</xsl:for-each>
</xsl:template>

<xsl:template name="printLI">
  <xsl:param name="node_set"/>
  <xsl:if test="$node_set[1][@style = 'LS1']">
    <li>
      <xsl:value-of select="$node_set[1]"/>
     </li>
  </xsl:if>
  <xsl:variable name="ns">
    <xsl:for-each select="$node_set[position() &gt;
1]">
      <para style="{@style}">
        <xsl:value-of select="."/>
       </para>
     </xsl:for-each>
  </xsl:variable>
  
  <xsl:for-each select="xalan:nodeset($ns)//para">
    <xsl:if test="(position() = 1) and (@style =
'LS1')">
    <xsl:call-template name="printLI">
	<xsl:with-param name="node_set"
select="xalan:nodeset($ns)//para"/>
    </xsl:call-template>
    </xsl:if>
  </xsl:for-each> 
</xsl:template>
</xsl:stylesheet>

i have tested the XSL on Xalan and its working fine..
i have used a nodeset extension.. You may change the
specifics arrording to your processor..

Mukul
