B4J Question regex.split help

[raphipps2002]

I have a spinner/combobox object with items made of two parts separated with '|'

The combobox's ID is cmbBankID

e.g. Bank|123

Paypal|345

Savings|987

I want to identify each part i.e. Payal and 345 or Savings and 987

Dim BID() As String
BID = Regex.Split("|",cmbBankID.Value)

Using Payal|345 But using the regex is get in Bid(0) = P and bid(1) = a

And not 'Payal' and '345' as expected.....

what am i doing wrong?

thanks

'|' is a special char in regular expressions used for 'or'. Therefore you must escape it, try '\|'.

I see....so how many special characters are there? Is it possible and safe therefore to put then escape all the time so cover all eventualities

The special characters are called "metacharacters", read this https://en.wikipedia.org/wiki/Regular_expression.
The escape cancels the special meaning of the special character when used in regex.
