I have the following string:
"You have selected: 7 Year Fixed Price 8.25¢/item"
How do I extract only "8.25" from this string in C#?
I have tried the following regex options:
(\d+)(?:\.(\d{1,2}))? and -?\d+(?:\.\d+)? but both extract only "7", which is the first number it finds.
For this specific example you can use a named capturing group and try something like this:
(?<float>\d+\.\d+)
Here is a quick demo: https://dotnetfiddle.net/Dm78d7
Use
\d+(?:\.\d+)?(?=\p{Sc}/item)
See proof.
Explanation
--------------------------------------------------------------------------------
\d+ digits (0-9) (1 or more times (matching
the most amount possible))
--------------------------------------------------------------------------------
(?: group, but do not capture (optional
(matching the most amount possible)):
--------------------------------------------------------------------------------
\. '.'
--------------------------------------------------------------------------------
\d+ digits (0-9) (1 or more times (matching
the most amount possible))
--------------------------------------------------------------------------------
)? end of grouping
--------------------------------------------------------------------------------
(?= look ahead to see if there is:
--------------------------------------------------------------------------------
\p{Sc} a currency sign
--------------------------------------------------------------------------------
/item '/item'
--------------------------------------------------------------------------------
) end of look-ahead
