[Qgis-user] How to split string values with separator

[Alexandre Neto]

I believe you need to do a custom function for that, you can use the
function editor and add this:

@qgsfunction(args='auto', group='Custom')
def split(string, separator, index, feature, parent):
    return string.split(separator)[index]

And you use it like this:
split("FieldName",',',1) --> cat
split("FieldName",',',2) --> spider
