hex to binary conversion for xml post

Hi guys,

i tried to send a simple sms with this text "12345"  (without quotes). The
request was done in XML POST  and i have received a strange sequence of
character. But  if the same request is done in GET i receive the correct
message. Smsbox when received a xml request extract the text so:

/* text */
    text = NULL;
    get_tag(*body, octstr_imm("ud"), &tmp, 0, 0);
    if(tmp) {
O_DESTROY(text);
text = octstr_duplicate(tmp);
if(octstr_hex_to_binary(text) == -1)
    octstr_url_decode(text);
O_DESTROY(tmp);
    }

with the text 12345: (but it is true for the all hex symbols)

octstr_check_range(ostr, 0, ostr->len, gw_isxdigit) is valid

and the function convert ascii data to binary values. This action compromise
my text.

I don't understand why for xml request smsbox do this check.


Please, can anyone explain the reason?!

thanks in advance
