I don't think you need a regex for this. Just populate a variable with the default text and do a replace() on the incoming text before you test it for length. Something like:
crap = "default crap from SoEditor"; content = replace(content, crap, ''); This way, if the default crap is submitted, it gets removed. Of course, if they only add to the beginning or end, you might run into trouble. You can either deal with this by checking the length against the length of the default content (what I'd do) or you can write an RE to do the replace (which seems like overkill and is easier to goof up). As far as good books go, Mastering Regular Expressions from O'Reilly is pretty good, though not CF specific. Of course, if you are using CFMX (almost?) everything that works in Perl will work. If you are using CF5, between Advanced CF5 Programming and Mastering RE's, you ought to be able to figure most things out. <cfx_evangelism really_cool_thing="CF-RegEx"> And, if you need advice or have more in-depth questions, you can always go to: http://www.houseoffusion.com/cf_lists/index.cfm?method=threads&forumid=21 to read, post, or subscribe to the HoF CF-RegEx list. So far, on the CF-Regex list, we've had discussions on the differences between CF5 and MX REs, workarounds for limitations to the CF5 RE engine, a posting on what looks like a very nice UDF for stripping HTMl/CFML/XML/*ML tags (or not stripping them) via REs, and several questions asked and answered. </cfx_evangelism> --Ben Doom Programmer & General Lackey Moonbow Software : -----Original Message----- : From: Brook Davies [mailto:brook@;maracasmedia.com] : Sent: Monday, October 21, 2002 2:48 PM : To: CF-Talk : Subject: SoEditor and RegEx help : : : Hello, : : I'm using the SoEditor wyiwyg Editor and I need some help with a regular : expression. The Soeditor when it is initially loaded prepopulates : the text : area with some basic html. Head and body tags etc. : : The problem I'm having with this is that if a user does not enter : anything, : it still looks like there is content in the textarea. I would like to be : able to say <cfif not (len(trim(form.textarea))> You did not enter : anything!</cfif>, but there will always be this default HTML in the : textarea. So my question is how do I ues Regular expressions : (which I know : next to nothing about) to strip out the default content and check : for user : entered content only. I'm sure that other SoEditor users would find this : useful, or maybe one of you have already done this? : : Here is the default code: : : <HTML> : <HEAD> : <META NAME="GENERATOR" Content="Microsoft DHTML Editing Control"> : <TITLE></TITLE> : </HEAD> : <BODY style="FONT-FAMILY: "> : <DIV> </DIV> : </BODY> : </HTML> : : Thanks for the help.
