Hello all,
I'd like to capitalize each word in an example set.
Source (all lower case):few major cities can claim to have a national park right on
their doorstep, but looming over central seoul, and forming a natural northern
boundary to the city, are the peaks of bukhansan national park spears and
spines of off-white granite that burst out of the undulating pine forests.
despite the park’s relatively small size at just 80 square kilometres, its
proximity to one of earth’s most populated cities makes it the world’s most
visited national park, drawing in upwards of five million visitors per year.
while an undeniably beautiful place, its popularity means that trails are often
very busy indeed – especially so on warm weekends – and some can be as crowded
as shopping mall aisles, hikers literally having to queue up to reach the
peaks.

I tried different approaches with RegEx but I couldn't achieve my goal. Maybe you can help me out? 
Kind regards,
