Help with regex_replace

[Joseph777]

Hi,

How do i change with regex_replace or other function

1. this 100 EUR (2.500 Kč) to this 2.500 Kč
2. this 10 EUR (250 Kč) to this 250 Kč
(amounts can be different)
3. How do i remove id="e67mde0d5_a6sd4" (in the id can be different characters)

This solution should be:
{$value|regex_replace:'anything':'anything'}

thanks

is it correct?
3. {$value|regex_replace:'/id=".*?"/':''}

1-2. {$value|regex_replace:'????????':'/\(.*?\)/'}
