You know how to do that kind of thing.but what if you want to (for example) replace any and all occurences of ' NATURALSIZEFLAG=[0-9]' with *nothing*? (Where [0-9] means *any* single digit number. The you would do this in the BBedit find/replace diolog box: SEARCH FOR: NATURALSIZEFLAG=[0-9] REPLACE WITH: (thats replace with *nothing*) turn on grep hit the replace all button.There are many other things you can do with regular expressions (grep). It means searching/replacing but while using *variables*. Now webcat can do this kind of 'smart searching/replacing' via [grep].I don't know how accurate the techno terms I used are, but you get the idea :-)-John Kim Ingram wrote:> Sorry for the stupidity if I missed something, but what the heck is Grep? > > > -----Original Message----- > > From: WebCatalog Talk [mailto:WebDNA-Talk@talk.smithmicro.com]On > > Behalf Of WebDNA Support > > Sent: Tuesday, July 04, 2000 1:51 AM > > To: WebCatalog Talk > > Subject: Re: How do I specify a & character in Grep? > > > > > > >And then some more hours trying to get around the ampersand thing. > > >I know Ampersand is not allowed in browser stuff, but, webcat source > > >never gets to the browser so I thought, since it is called grep I > > >could use the standard \ to delimit a reserved character.
