match() Function

Julia provides an inbuilt match() function, which searches for the first match of the given regular expression in the specified string.
Its syntax is match(r, s, idx) where r is a regular expression, s is a specified string, and idx is an integer that specifies the point from which the searching gets started.

println(match(r"m....y", "The monkey climbed on a tree"))
println(match(r"^\w+", "This is a test"))

eachmatch() Function

Julia provides an inbuilt eachmatch() function that returns an iterator over RegexMatch objects, suitable for loops.
Its syntax is eachmatch(r, s, overlap) where r is a regular expression, s is a specified string, and overlap is a boolean value that allows matching sequence if true.

for i in eachmatch(r"(monkey|climbed)s?", "The monkey climbed on a tree")
    println("Matched $(i.match) at index $(i.offset)")
end
