taks is to pasrse the given html page and evaluate the
contents of scirpt tags using rhino.

first please let me know where can i find some good
examples for working with httpunit in mauplating the
dom of a html page.

Then if a script tag in the page has 4 or 5 functions
<script>
f1()
f2() {}
f3( ){f4(){}}
f5() {}
</script>

indivudula function as per need 
when i get the contents with tag name script from DOM

but from this can i acess the indivudual function
using httpunit
