Re:  position matching
Hai

Based on Michael points i have updated the XSL but I am not getting
any output. Please help me.
<xsl:template match="map">
<xsl:if test="count(child::source) = count(child::target) and
count(child::*) != 2">
				<xsl:variable name="pos"><xsl:value-of
select="target[position()]"/></xsl:variable>
				<mac:template match="{source[$pos]}">
					<mac:element name="{target[$pos]}">
						<xsl:for-each select="target[$pos > 1]">
						<mac:attribute name="substring-after({target[$pos]},'@')">
							<mac:value-of
select="(preceding-sibling::source)[$pos]"/>
							</mac:attribute>
						</xsl:for-each>
					<mac:apply-templates select="@*|node()"/>
					</mac:element>
				</mac:template>
			</xsl:if>
</xsl:template>

Regards,
Ganesh
