Regex to extract text between two strings The approach we've worked out for pulling out text between two characters will also work for extracting text between two strings. For example, to get everything between "test 1" and "test 2", use the following regular expression. Pattern: test 1(....
In the test1 function, I’m creating a regular expression that matches either a capital or lowercase S, followed by one or zero single characters followed by e. In other words, I’m matching Se and se, possibly with a single character between the two letters. I then create the string th...

but only that part of it does. For this exposition, consider the problem of a programmer who expects to have forgotten one or two calls to delete in his program. Although he realizes that

and anything following is ignored; in that case, the third string will match the pattern. Or a system can be told that the string must not have any characters after the pattern, in which case our third string will not match the pattern. The default rule with the Boost library I’ll be...
Aboundis `{' followed by an unsigned decimal integer, possibly followed by `,' possibly followed by another unsigned decimal integer, always followed by `}'. The integers must lie between 0 and RE_DUP_MAX (255(!)) inclusive, and if there are two of them, the first may not exceed the...
parts thereof in the replacement. This website also includes a completereplacement strings tutorialthat explains this syntax. While replacement strings are fairly simple compared with regular expressions, there is still great variety between the syntax used by various applications and their actual ...
To find strings that do NOT contain a certain character, you can use negated character classes [^ ] that match anything NOT in brackets. For example: [^13] will match any single character that is not 1 or 3. [^1-3] will match any single character that is not 1, 2 or 3 (i.e...
So instead of remembering anything above, you should just switch to always safely escaping regex syntax via regex. Interpolating partial patterns As an alternative to interpolating RegExp instances, you might sometimes want to interpolate partial regex patterns as strings. Some example use cases: ...
