String Split to array

RouterOS Scripting
1

Hi I was wondering is there is a prebuild function or a script which can split strings to arrays for a given operator?

ex: "5489->12->59->15663" this will have the split operator "->" and the output will be an array of 
{
	5489
	12
	59
	15663
}

More complex (array of array)

ex: "5489->12;59->15663" this will have the split operators ";" and "->" and the output will be an array of
{
	{
		5489
		12
	}
	{
		59
		15663
	}
}

No.

:find “->” and :pick the right parts.
For multiple array, run multiple times.

Yup, the only “built-in split()” is via :toarray which works with comma-separated values.

In generally, it best to do data parsing before it get’s to the Mikrotik, since there aren’t good primitives like splice(), split(), trim(), etc… There is just :find and :pick as @rextended explains - which is the basic building block of any of those, so possible, just tedious.
