XML can handle complex formats, such as 7z format. The 7z format is as follow: $7z$0$19$0$1122$8$d1f50227759415890000000000000000$1412385885$ data_length $112$ data The valid() function require strlen(data) == data_length * 2. Complex hash formats like 7z can be handled with XML. But it's impossible for the expression like "$siemens-s7$1$%40h$%40h". I think the expression is good but it can handle complex hash format. If we want to fuzz valid(), the expression like "$siemens-s7$1$%40h$%40h" is ok. If we want to fuzz functions after valid(), the expression can not do that. Thank you, sincerely Kai Content of type "text/html" skipped
