String splitting without loosing punctuation marks
 

Hi,
I need a little help on performing string manipulation:
I want to take a given string, and make certain words hyperlinks.
For example:
"Hello world, this is a wonderful day!"
I'd like the words world & and day to be hyperlinks, therefore
after my manipulation it should be:
"Hello <a href=...>world</a>, this is a wonderful <a href=...>day</a>!"
Using split method is not good, because splitting with regex each
punctuation mark causes the commas and other punctuation marks to
disappear.
Instead of displaying
"Hello <a href=...>world</a>, this is a wonderful <a href=...>day</a>!"
I will display
"Hello <a href=...>world</a> this is a wonderful <a href=...>day</a>"
(note that the comma and exclamation mark are gone).
Any ideas on how I can locate words, replace them but not loose
punctuation marks on the way?
Thanks a lot!!!
Anat.

The words are "losing" and "lose", not "loosing" and "loose".
Split on whitespace and then handle punctuation separately.

.... and these words were chosen because they are just before
punctuation, I guess.

If you want to replace parts of a string ... use the replace function:

string.replace(/\b(\w+)([.,!?])/g, "<a href=\"...\">$1<\/a>$2")

Replace and keep the punctuation mark in the replacement.
