[xsl] looping in increments

[Vijay Malgari <vmalgari@xxxxxxx>]

Hello All:

I did go through the FAQ's list and I could not
find any help or to say any lead.  Please do ignore
if my question is trivial.

I have a block of code that I want to repeat for
different integer values and I have no clue how to do
the increment while looping the same block of xsl code.

Here is the code: 
I want to repeat the same block
for all Feature[] values...

<xsl:if test="descendant::Feature[1]">
               <fo:block-container reference-orientation="90" 
inline-progression-dimension.minimum="5mm" 
inline-progression-dimension.optimum="15mm" 
inline-progression-dimension.maximum="auto">
                   <fo:block>
                       <xsl:if test="descendant::Attribute">
                           <xsl:for-each 
select="descendant::Feature[1]/Attribute">
                               <fo:block-container 
reference-orientation="-90" inline-progression-dimension="35mm" 
width="1.5in">
                                   <fo:block font-size="6.5pt">
                                       <xsl:value-of select="@value"/>
                                   </fo:block>
                               </fo:block-container>
                               </xsl:for-each>
                       </xsl:if>
                   </fo:block>
               </fo:block-container>
           </xsl:if>

Any help/lead  is greatly appreciated,
Thanks,
Vijay
