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.

Hi all,

 

Is the some way to stop the following behaviour of the "sub" function in the
"regexp" module

 

Str1 = "String with & character"

Str2 = "Replace the following tag <replace> with str1"

 

regexp:sub(Str2, "<replace>", Str1).

 

 

{ok, NewStr, Count} = regexp:gsub(Str1, ["<ad2>"], Ad2). 

NewStr.

"Replace the following tag String with <replace> character with str1"

 

The <replace> is replaced by the content of Str1, but the & character in
Str1 has been replaced by the 

replaced character set <replace>. is there some way to stop this from
happening.

 

Thanx

Shehan
