String Replace and Search with Regular Expressions
Text used for string.replace() and string.search() methods:

Whether ‘tis nobler in the mind to suffer
The slings and arrows of outrageous fortune,
Or to take arms against a sea of troubles,
And by opposing end them.
Enter a regular expression to match:
Case-sensitive
Enter a string to replace the matching strings:
Result:
string.search(regExpression)
