numbering across different elements

[Mike Dickens]

hi,
suppose i have:

<a>
<b i="Y" j="aaaa"/>
<c i="N" j="bbbb"/>
<d i="Y" j="cccc"/>
<e i="N" j="dddd"/>
<f i="N" j="eeee"/>
<g i="Y" j="ffff"/>
</a>

and i want to extract the elements where i="Y" such that i get something like
<x>
<y>1. aaaa</y>
<y>2. cccc</y>
<y>3. gggg</y>
</x>

how would i get the numbering to work across the different elements?

thanks,
mike

If you can compile a Bash shell, then

start () {
local "$@" # b i=Y j=aaaa
[ "$i" = Y ] && echo $((++count)). $j
}
xml -s start "`< file.xml`"

will print

1. aaaa
2. cccc
3. ffff
