Re: automatic creation of nested elements

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


I am getting to think that you are not thinking XSL :).. Please take your
time to get some interest in XSL coding. You will find that your question
was not difficult to solve.

Also, you did not mention any specific rule for the apply-templates. So I
assumed that you do not need for the first target.

Please make a diff between what you had with this.. And you will find some
interesting differences.

Dear All, 
 
Input XML: 
 
<map> 
<source>bib-reference</source> 
<source>@id</source> 
<source>@class</source> 
<target>reference/citation</target> 
<target>@id</target> 
<target>@type</target> 
</map> 
 
Required output: 
 
<xsl:template match="bib-reference"> 
<xsl:element name="reference"> 
<xsl:element name="citation"> 
<xsl:attribute name="id"> 
<xsl:value-of select="@id"/> 
</xsl:attribute> 
<xsl:attribute name="type"> 
<xsl:value-of select="@class"/> 
</xsl:attribute> 
<xsl:apply-templates/> 
</xsl:element> 
<xsl:element> 
</xsl:template> 
 
 
 
Stylesheet used: 
 
<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="{$element}"> 
<xsl:for-each select="target"> 
<xsl:if test="not($position = 1) and 
Exists(source[2])"> 
<mac:attribute 
name="{substring-after(target[$position],'@')}"> 
<mac:value-of 
Select="{source[$position]}"/> 
</mac:attribute> 
</xsl:if> 
</xsl:for-each> 
<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> 
 
 
Ouput with the above stylesheet: 
 
<xsl:template match="bib-reference"> 
<xsl:element name="reference"> 
<xsl:element name="citation"> 
<xsl:attribute name="id"> 
<xsl:value-of select="@id"/> 
</xsl:attribute> 
<xsl:apply-templates/> 
</xsl:element> 
<xsl:apply-templates/> 
<xsl:element> 
</xsl:template> 
 
In the resultant output I am getting template only for first attribute 
and 2nd attribute is missing. 
<xsl:apply-templates> is appearing twice resulting duplication of the 
content. Please suggest how to get the required output. 
 
Thanks & Regards, 
Ganesh
