== Icon and Unicon == |

The {{libheader|Icon Programming Library}} provides [http://www.cs.arizona.edu/icon/library/procs/regexp.htm regexp]. Regex includes procedures to provide access to regular expressions within native string scanning and matching expressions. 'ReFind' and 'ReMatch' respectively generate the sequence of beginning and ending positions matched by a regular expression. Additionally, there is a regular expression pattern compiler 'RePat' and other supporting functions and variables. |

==={{header|Icon}}=== |
|||
<lang Icon>procedure main() |
|||
s := "A simple string" |
|||
p := "string$" # regular expression |
|||
s ? write(image(s),if ReFind(p) then " matches " else " doesn't match ",image(p)) |
|||
s[j := ReFind(p,s):ReMatch(p,s,j)] := "replacement" |
|||
write(image(s)) |
|||
end |
|||
link regexp # link to IPL regexp </lang> |
|||
Sample output:<pre>"A simple string" matches "string$" |
|||
"A simple replacement"</pre> |

The Icon solution works in Unicon. |
