splitting columns into new columns

[nayan sharma]

I’ve a Dataframe where in some columns there are multiple values, always 
separated by ^

phone|contact|
ERN~58XXXXXX7~^EPN~5XXXXX551~|C~MXXX~MSO~^CAxxE~~~~~~3XXX5|

phone1|phone2|contact1|contact2| 
ERN~5XXXXXXX7|EPN~58XXXX91551~|C~MXXXH~MSO~|CAxxE~~~~~~3XXX5|
How can this be achieved using loop as the separator between column values
are not constant.

data.withColumn("phone",split($"phone","\\^")).select($"phon‌​e".getItem(0).as("ph‌​one1"),$"phone".getI‌​tem(1).as("phone2”))
 I though of doing this way but the problem is  column are having 100+ 
separator between the column values



Thank you,
