Hi Gunjan,
The answer depends on what kind of 'rules' you have for cleaning up the
text. Do you simply want to delete words based on their position in the
text, or are you trying to determine the meaning of the text and 'prune' it
to a simplified version? If its the latter, then the answer is quite complex
- basically you are asking how to create a language parser.
If you just want to delete words based on their position in the text, then
you do it something like this
aa="hello everyone... i am gunjan"
firstWordToDelete = 2 -- keep first word
LastWordToDelete = aa.word.count - 1 -- keep last word
if LastWordToDelete >= firstWordToDelete then
delete aa.word[firstWordToDelete..LastWordToDelete]
else
-- not enough words; the rule fails
end if
