binary expression with fixed and variable fields
Tue Jun 29 19:22:01 CEST 2010
I have a string composed of several fixed and variable fields. I would like to parse this string as binary expression.
I checked the example with an IP datagram (the variable fields are to the end ...):
If the size3 of the field3 is variable,how to parse the string ?
<<field1:size1,field2:size2,Rest/binary>> but after ?
If a field is empty, how to detect it ?
If a char (e.g comma) is between each field, is it always possible to use the binary syntax ?
Does exist a general approach in Erlang ?
