Generate numbers in incremental order, the number of times condition met?

Question

I have tried explaining my problem here also.
http://saloon.javaranch.com/cgi-bin/ubb/ultimatebb.cgi?ubb=get_topic&f=31&t=007531&p=1
But trying to put in other words now.
I have a NO tag which appears many times in xml. and alwyas have some random numbers displaying.
output looks something similar to this
something......<NO>1</NO>
something......<NO>1</NO>
something......<NO>2</NO>
something......<NO>1</NO>
something......<NO>3</NO>
something......<NO>1</NO>
something......<NO>5</NO>
something......<NO>1</NO>
something......<NO>1</NO>
something...... & so on.
Now instead of these numbers coming in this order i prefer to display in final output file as
1 2 3 4 5 .................... n
Is it possible in any ways using xslt.
DO we need to ignore the values given in input file and then generate output values for same.
it can be like the number of times NO tag appears in xml, it should start from 1 and keep increasing value by 1, until NO tag finishes appearance.
But next time when other xml transforms it again should be able to start from 1 till n.
is there a possibility of using java code for this situation or xslt is capaable enough to handle this.
Thanks

I'm guessing you are looking for something like this. I used a pull approach but it could be done with a push (xsl:for-each).
Sample XML
<?xml version="1.0" encoding="UTF-8"?>
<root>
     <NO>1</NO>
     <NO>1</NO>
     <NO>2</NO>
     <NO>1</NO>
     <NO>3</NO>
     <NO>1</NO>
     <NO>5</NO>
     <NO>1</NO>
     <NO>1</NO>
</root>
Sample XSLT
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
     <xsl:output method="xml" version="1.0" omit-xml-declaration="yes" encoding="UTF-8" indent="yes"/>
     <xsl:template match="root">
          <output>
               <xsl:apply-templates select="NO"/>
          </output>
     </xsl:template>
     <xsl:template match="NO">
          <row>
               <xsl:value-of select="position()"/>
          </row>
     </xsl:template>
</xsl:stylesheet>
Sample Output
<output>
     <row>1</row>
     <row>2</row>
     <row>3</row>
     <row>4</row>
     <row>5</row>
     <row>6</row>
     <row>7</row>
     <row>8</row>
     <row>9</row>
</output>
