rereplace for removing repeating characters
Hi, i need to replace all repeating commas in a string with only one comma, plus remove the trailing comma, have tried a few different routes unsuccessfully and would appreciate any input: for example i would the the string: 'Genns,,DrBish Stratford,,,' to become: 'Genns,Dr,Bish Stratford' thanks ~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:338747 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
Re: rereplace for removing repeating characters
I am sure there are some nice slick regular expressions to do this, but I just simply do this a very dumbed down way. cfset myVar = ReplaceNoCase(myVar , ,, ,, ALL) cfset myVar = ReplaceNoCase(myVar , , ,, ALL) cfset myVar = ReplaceNoCase(myVar , ,, ALL) cfset myVar = ReplaceNoCase(myVar , ,,, ,, ALL) You could also write a loop to run until FindNoCase(myVar, ,,) EQ FALSE, so you keep turning double commas, into single commas which will continue to reduce the commas, until there are no matches. Again, there is probably a RegEx way to do this, but I don't know RegEx off the top of my head.

Re: rereplace for removing repeating characters
thanks for the reply, i actually just found a shortcut! i converted the string to an array which removed any empty array elements, and then converted back to a list and therefore deleted all the duplicate, and trailing commas I am sure there are some nice slick regular expressions to do this, but I just simply do this a very dumbed down way. cfset myVar = ReplaceNoCase(myVar , ,, ,, ALL) cfset myVar = ReplaceNoCase(myVar , , ,, ALL) cfset myVar = ReplaceNoCase(myVar , ,, ALL) cfset myVar = ReplaceNoCase(myVar , ,,, ,, ALL) You could also write a loop to run until FindNoCase(myVar, ,,) EQ FALSE, so you keep turning double commas, into single commas which will continue to reduce the commas, until there are no matches.

try this: cfset string = rereplace(rereplace(string, ,+$, ), ,+, ,, all) Azadi On 02/11/2010 20:34 , Richard White wrote: Hi, i need to replace all repeating commas in a string with only one comma, plus remove the trailing comma, have tried a few different routes unsuccessfully and would appreciate any input: for example i would the the string: 'Genns,,DrBish Stratford,,,' to become: 'Genns,Dr,Bish Stratford' thanks ~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:338751 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
