[xsl] RE: Counting preceding elemets of similar node, but in different branch

I have requirement to display certain id's in a sequential numbering
order. My xml is something like [and pls ignore any spell / case
mistakes]

        <root>
                <something>
                        <assessQ>
                                <header/>
                                <Block>
                                        <blockID>xxxx</blockID>
                                        <questions>
                                                <QUESTION ID="1" />
                                                <QUESTION ID="2" />
                                                <QUESTION ID="3"/>
                                        </questions>
                                </Block>
                        </assessQ>
                        <assessQ>
                                <header/>
                                <Block>
                                        <blockID>yyy</blockID>
                                        <questions>
                                                <QUESTION ID="1" />
                                                <QUESTION ID="2" />
                                        </questions>
                                </Block>
                        </assessQ>
                </something>
        </root>         
        
And in my xslt (Ver 1), I have something like <xsl:apply-templates
select="something/assessQ/Block/questions"/> [I think I cannot change
this due to various other elements]
        
And what I am do is something like
1= 1
2= 2
3= 3
4= 1
5= 2 and so on....

so, i tried to use position, 

<xsl:template match="QUESTION">
        <xsl:value-of select="position()"/> = <xsl:value-of
select="@ID"/><br/>
</xsl:template> 

but I released the mistake after seeing the result, 3=3 is being
followed by again by 1=1, ... instead of 4=1.

So, i think i must use preceding-sibling and/or some other logic to
calculate how many <QUESTION/> elements are there before it. Pls can you
suggest the best way to handle this? Hope there might be some solution?

Thanks,
karl
