BBCode ("Bulletin Board Code") is a lightweight markup language used to format messages in much Internet forum software, first introduced in 1998. The available "tags" of BBCode are usually indicated by square brackets (

 /code> and /code>) surrounding a keyword, and are  parsed before being translated into HTML

  Implementation 

BBCode is typically implemented by applying a series of regular expression 




A regular expression (shortened as regex or regexp; sometimes referred to as rational expression) is a sequence of  characters that specifies a  search pattern in  text. Usually such patterns are used by  string-searching algorithms for "find"  ...
 string-replace operations upon the input. Because regular expressions are limited in analyzing the structure of text input, this has the artifact that any non-hierarchical BBCode input will be transformed into invalid non-hierarchical HTML without error.

Applying traditional parsing techniques is made difficult by ambiguities in the markup, such as in , where the input can either be interpreted as "text" quoted from someone called , or the bolded text "text" surrounded by  and {{code, lang=bbcode, code= quote}, i.e.  uote=text[/quote/code>.
