Hi there,
I am sure there is an efficient way to extract some part of a string.
I have a string which looks like this:
...<br />% countries: <b>73%</b><br />% population: <b>98%</b><br />%
economy (GDP): ....
Now, I would like to extract the value which is to be found behind the
"population: <b>".... As the string can vary in length I can't use a
substring_number-from-left... thing. I could split the string behind
"population: ", than eliminate "<b>" etc... But that seems rather
complicated and ugly.
Can anyone give be a hint how I can achieve that nicely?
Thanks for any advice.
Stef
