finding a specific text value in a string

[admin]

I want to find the value of a specific string but cannot seem to do it, for example
mySting = "my name = goran"
i need to find the string 'my name = '
and through that i need to get the value of 'my name'

so far this is all i got:

myString = "my name = goran"
theResult = myString.indexOf("my name = ")

dont know how to get the value and remember that 'goran' changes, it dosent stay the same value...


Thanks
Goran
