[erlang-questions] regexp behaviour

[Robert Virding]

Hi,

If you quote the '&' character with \ then you will get a & in the out put
string. So

Str1 = "String with \\& character"

N.B. you need an extra \ because it is in a string and the string parsing
converts \\ into \ in the resultant string.
