Re: [xsl] automatic creation of nested elements

["Vasu Chakkera" <vasucv@xxxxxxxxx>]

Try the below. ( i just carried it along the way of creating the
children recursively from your target. add your attributes etc as
necessary ). just changed from where you had a for-each. Dint check
the other parts of your code. The below produces the result you
wanted.

<xsl:template match="map">
		<xsl:if test="count(child::*) &gt; 3 and not(starts-with(source,'@'))">
			<mac:template match="{source[1]}">
				<xsl:variable name="nestedele"
select="tokenize(target[1],'/')"/>
				<xsl:call-template name="buildtree">
					<xsl:with-param name="position" select="1"/>
				</xsl:call-template>
			</mac:template>
		</xsl:if>
	</xsl:template>
	<xsl:template name="buildtree">
		<xsl:param name="position"/>
		<xsl:variable name = "element" select="tokenize(target[1],'/')[$position]"/>
		<xsl:if test = "string($element)">
			<mac:element name="{$element}">
				<xsl:if test="not($position = 1) and exists(source[2])">
					<mac:attribute name="{substring-after(target[$position],'@')}">
						<mac:value-of select="{source[$position]}"/>
					</mac:attribute>
				</xsl:if>
				<xsl:call-template name="buildtree">
					<xsl:with-param name="position" select="$position +1"/>
				</xsl:call-template>
				 <mac:apply-templates/>
			</mac:element>
		</xsl:if>
	</xsl:template>
