Allowing specific HTML tags to be displayed
All-- I've still not had any luck trying to get Replace or ReReplace to allow a set of specific codes when displaying information from a database. I'm hoping to allow for only specific sets: Italics, Bold, A HREF and IMG SRC and I'm baffled as to how to get this to work. It's a bit of a repost, but I'm really striking out.

Re: Allowing specific HTML tags to be displayed
Hey Russ -- I already know what Matt's going to recommend ant that's using cfimport with an empty prefix value which will allow you to specify a directory of CF modules to replace the html tags. It's not a bad solution, however, the problem you're going to have is that you need 1 tag for each html element someone might type into the form, so ... to avoid that kind of work-creep, you might want to check out the StripTags() function that can be found both in the open-source API in my sig and on www.cflib.org. cfset thedata = striptags(allow,a,b,i,img,thedata) This syntax will remove any xml-style tag that's not a link (or anchor), bold, italic or html image tag from the string. Note that it doesn't currently remove anything but the tags themselves, so given the string hello blinkworld/blink it would return hello world, not hello . You'll probably want to do this _before_ the data goes into the db if possible because it's a reasonably large function with a lot of string manipulation. hth s. isaac dealey954-776-0046 new epoch http://www.turnkey.to lead architect, tapestry cms http://products.turnkey.to tapestry api is opensource http://www.turnkey.to/tapi certified advanced coldfusion 5 developer http://www.macromedia.com/v1/handlers/index.cfm?ID=21816 Are you running CF5 or CFMX? - Original Message - From: Russ [EMAIL PROTECTED] To: CF-Talk [EMAIL PROTECTED] Sent: Tuesday, February 25, 2003 8:16 AM Subject: Allowing specific HTML tags to be displayed All-- I've still not had any luck trying to get Replace or ReReplace to allow a set of specific codes when displaying information from a database.

RE: Allowing specific HTML tags to be displayed
I'm having difficulty ONLY allowing the following characters: b/bi/ia href=etc/aimg src=etc Right now, I have nothing allowed, but I'd like to allow linking and images, at the very least and the others are a bonus. So, I don't want to allow things like td that isn't closed--because it can break the display. No one wants that, you know?

RE: Allowing specific HTML tags to be displayed
Since the volume will be more than a few, I'd make sure you do any data manipulation ON THE WAY IN. It will cost too much to do it on the fly while displaying. For now, we will get it working this way. But to recap. 1. pull data from db you obviously know how to do this 2. remove any tags not in the following list: b/bi/ia href=etc/aimg src=etc here, use the function from Isaac: cfset thedata = striptags(allow,a,b,i,img,thedata) 3. display the resulting data as HTML cfoutput#theData#/cfoutput That should be all there is to it.

RE: Allowing specific HTML tags to be displayed
You could always do things the way UBB et.al. do it. In other words, don't allow any HTML, but do allow certain codes with a different marker (UBB uses []) that you will replace with HTML on the fly. I can't imagine anyone hasn't encountered a UBB discussion forum yet, but for completeness, here's an example: This text is [b]bold[/b], this is [i]italic[/i] and this is [link url=http://www.m-w.com/]a link[/link].

RE: Allowing specific HTML tags to be displayed
2. remove any tags not in the following list: b/bi/ia href=etc/aimg src=etc here, use the function from Isaac: cfset thedata = striptags(allow,a,b,i,img,thedata) I love helping people. :) Incidentally, as Russ was mentioning, yes, you shouldn't do this on the fly with more than a few visitors. Particularly with the StripTags UDF as it's written, because the tag does a lot of extra validation (granted it's all regex, but still) for things like white space inside the and characters, for instance, if someone enters td or / td these will be stripped the same as td and /td, and all of the searching the string for a handfull of different tags and then removing that tag (or something that's not that tag) is rather labor intensive for the server, so since your inserts and updates will usually be on a ratio of somewhere between 1/10 and 1/1000+ to your page views, you really want to do all that before the insert or update and save somewhere between 9/10ths and all but a couple parts per million processing time.

It's not a bad solution, however, the problem you're going to have is that you need 1 tag for each html element someone might type into the form, so ... to avoid that kind of work-creep, you might want to check out the StripTags() function that can be found both in the open-source API in my sig and on www.cflib.org. cfset thedata = striptags(allow,a,b,i,img,thedata) This syntax will remove any xml-style tag that's not a link (or anchor), bold, italic or html image tag from the string. Note that it doesn't currently remove anything but the tags themselves, so given the string hello blinkworld/blink it would return hello world, not hello . You'll probably want to do this _before_ the data goes into the db if possible because it's a reasonably large function with a lot of string manipulation. hth s. isaac dealey954-776-0046 new epoch http://www.turnkey.to lead architect, tapestry cms http://products.turnkey.to tapestry api is opensource http://www.turnkey.to/tapi certified advanced coldfusion 5 developer http://www.macromedia.com/v1/handlers/index.cfm?ID=21816 Are you running CF5 or CFMX? - Original Message - From: Russ [EMAIL PROTECTED] To: CF-Talk [EMAIL PROTECTED] Sent: Tuesday, February 25, 2003 8:16 AM Subject: Allowing specific HTML tags to be displayed All-- I've still not had any luck trying to get Replace or ReReplace to allow a set of specific codes when displaying information from a database.

Re: Allowing specific HTML tags to be displayed

I'm hoping to allow for only specific sets: Italics, Bold, A HREF and IMG SRC and I'm baffled as to how to get this to work. It's a bit of a repost, but I'm really striking out. Here is how I would approach it: 1. Use the ReplaceList() function to replace all permitted tags and matching end-tags with tokens unique to each tag. The tokens will have to be fairly unique - using control characters would be a good idea to replace the brackets. cfset bmarker = Chr(2) cfset emarker = Chr(3) cfset mystring = ReplaceList(mystring, b,i,u,/b,/i,/u, #bmarker#b,#bmarker#i,#bmarker#u,/b#emarker#,/i#emarker#,/u#emarker#) 2. Invalidate all of the remaining HTML by either stripping out the entire HTML tags, or by turning the and into special lt; and gt; characters. You can do the latter with: cfset mystring = ReplaceList(mystring, ,, lt;,gt;) 3. Replace the tokens with their original tags (i.e. reversing step 1). cfset mystring = ReplaceList(mystring, #bmarker#b,#bmarker#i,#bmarker#u,/b#emarker#,/i#emarker#,/u#emarker#, b,i,u,/b,/i,/u) Jim ~| Archives: http://www.houseoffusion.com/cf_lists/index.cfm?forumid=4 Subscription: http://www.houseoffusion.com/cf_lists/index.cfm?method=subscribeforumid=4 FAQ: http://www.thenetprofits.co.uk/coldfusion/faq Signup for the Fusion Authority news alert and keep up with the latest news in ColdFusion and related topics. http://www.fusionauthority.com/signup.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4
