Simple regex help in coldfusion -

i have string wish remove characters based on underscores in string. instance.

i wish change

2_master bedroom_cfm 

to

master bedroom 

or

2734923ie_bedroom 2_cfm 

to

bedroom 2 

any recomendations on how coldfusion?

coldfusion has gettoken() function, makes manipulating string delimiter (virtually delimiter) easy. assuming each string you're looking parse 2 sets of strings output master bedroom

<cfset string1 = '2_master bedroom_cfm'> <cfset firstword = listfirst(string1,' ')> <cfset firstword = gettoken(firstword,2,'_')> <cfset secondword = listlast(string1,' ')> <cfset secondword = gettoken(secondword,1,'_')>  <cfoutput>   #firstword# #secondword# </cfoutput> 

could simplify down just

<cfset string1 = '2_master bedroom_cfm'> <cfoutput>   #gettoken(listfirst(string1,' '),2,'_')# #gettoken(listlast(string1,' '),1,'_')# </cfoutput> 

edit leigh points out in comments use

gettoken("2_master bedroom_cfm", 2, "_") 

this treats string list elements 2, master bedroom, , cfm
