I have the following code in ColdFusion 8
<cfcase value = "envelope, addrfile">
This works fine and all is correct when the value is envelope, but when the value is addrfile the case is not executing. When I remove envelope and just write
<cfcase value = "addrfile">
the case is executed and everything is correct. The documentation says, and I quote: One cfcase tag can match multiple expression values. To do this, separate the matching values with the default value of the delimiter character. For example the following line matches "red", "blue", or "green":
<cfcase value="red,blue,green">
Can anyone suggest a reason this might not be working for me? Or a workaround that doesn't involve duplicating all the code in the case?
I suggest removing the spaces between the elements.
<cfcase value="envelope,addrfile">

I'm trying to figure out a way to implement text qualifiers (surrounding quotes) in cfloop lists. cfloop list doesn't seem to have an option for ignoring text between certain characters. Of course I could just change the delimiter but I'm surprised I can't figure out a more elegant way to do this and now it's got me curious...
Here is the list I'm looping through:
Mockup_"/docs/R0001/Mockup_2014-07-10.pdf"_MDEXTER_2014-07-10
And of course this is the loop:
<cfloop list="#list#" delimiters="_" index="i">
#i#
</cfloop>
So it is treating
"/docs/R0001/Mockup
and
2014-07-10.pdf"
as separate elements whereas they need to form one URL. Any suggestions?
If the line of text is going to be relatively constant why not do this?
strList1 = listGetat('Mockup_"/docs/R0001/Mockup_2014-07-10.pdf"_MDEXTER_2014-07-10',2,'"');
writeDump(strList1);
The above will produce this without quotes: "/docs/R0001/Mockup_2014-07-10.pdf"
Again this assumes a standard format.
I'm building a form through which users will be able to submit articles. my current regex allows only certain characters and works as it should, though I do not know how to allow quotes as well. here is the code
<cfif refind ("[^A-Z a-z 0-9\\+\-\?\!\.\,\(\)]+", trim(form.articleText)) and len (trim(form.articleText)) gte 15>
<cfset msg = "The article can not contain special characters.">
</cfif>
I tried using " as in c# but it does not work!
Add quotes in your character class:
<cfif refind ("[^A-Za-z0-9 +?!.,()\\""'-]+", trim(form.articleText)) ...
anubhava's answer gives you what you've asked for, but the solution you probably need is actually something completely different: to use the ESAPI encodeForX functions in CF10 to encode the output appropriately for its context, such as encodeForHtml, instead of trying to restrict what characters can be written and constantly having to update it.
At most, you might want something such as:
<cfif refind('[[:cntrl:]]',form.articleText) >
<cfset msg = "The article can not contain control characters.">
</cfif>
Which will block unprintable control characters, whilst not preventing perfectly reasonable characters such as accented letters, currency symbols, and so on.
I want to get string between em tag , including other html also.
for example:
<em>UNIVERSALPOSTAL UNION - International Bureau Circular<br />
By: K.J.S. McKeown</em>
output should be as:
UNIVERSALPOSTAL UNION - International Bureau Circular<br />
By: K.J.S. McKeown
please help me.
Thanks
Use the regular expression function like this:
REMatch("(?s)<em>.*?</em>", html)
See also: http://livedocs.adobe.com/coldfusion/8/htmldocs/help.html?content=regexp_01.html
The (?s) sets the mode to single line, so that the input text is interpreted as one line even if it contains line feeds. This is probably the default (I'm not sure) so it can be omitted. As Peter pointed out in a comment, this is not the default and therefore must be set.
The .*? matches all characters inbetween <em> and </em>. The questionmark after the multiplier makes it "non-greedy", so that as few as possible characters are matched. This is needed in case the input html contains something like <em>foo</em><em>bar</em> where otherwise only the outermost <em></em> tags are considered.
The returned array contains all matches found, i.e. all texts including html that was in <em> tags.
Note that this could fail for circumstances where </em> also occurs as attribute text and is incorrectly not html-encoded, for example: <em><a title="Help for </em> tag">click</a></em> or in other rare circumstances (e.g. javascript script tags etc.). A regex cannot replace a full HTML/XML parser and if you need 100% accurateness, you should consider using one: http://livedocs.adobe.com/coldfusion/8/htmldocs/help.html?content=functions_t-z_23.html
If your input is exactly in the format given above, you don't even need regex - just strip the outer tags:
<cfsavecontent variable="Input">[text from above]</cfsavecontent>
<cfset Output = mid( Input, 4 , len(Input) - 9 />
If your input is more than this (i.e. a significant piece of HTML, or a full HTML document), regex is still not the ideal tool - instead, you should be using a HTML parser, such as JSoup:
<cfset jsoup = createObject('java','org.jsoup.Jsoup') />
<cfset Output = jsoup.parse(Input).select('em').html() />
(With CF8, this code requires placing the jsoup JAR file in CF's lib directory, or using a tool such as JavaLoader.)
If you are using jquery you can do this also pretty easily.
$("em").html();
Will return all html between the em tags.

I had to remove any text that was to follow after a partiucular tag . Now the HTML content was getting generated dynamically from a database that cater to 5 different langauges. so I only had the div tag to help me. I am not sure why REMatch("(?s).*?", html) did not work for me. However Ben helped me here (http://www.bennadel.com/blog/769-Learning-ColdFusion-8-REMatch-For-Regular-Expression-Matching.htm). My code looks like tghis:
<cfset extContentArr = REMatch("(?i)<div class=""inlineBlock"" style=""margin-right:30px;"">.+?</div>",qry_getContent.colval) />
<cfif !ArrayIsEmpty(extContentArr)>
Loop the array and do whatever you need with the extract , I just deleted them.
</cfif>
I'm writing a web service in ColdFusion. The problem is that I cannot figure out how to get rid of the comma after the last element. My code looks like this:
<cfoutput query="Attachments">
#url#,
</cfoutput>
Which produces output like this (notice the trailing comma)
url1,url2,url3,
How can I get rid of the trailing comma and produce this instead?
url1,url2,url3
This is an easy method:
<cfoutput>#ValueList(Attachments.url)#</cfoutput>
Jake's answer is what's needed in this particular case.
For more generic cases, you can do this:
<cfloop ...>
<cfset myList=listAppend(myList,value)>
</cfloop>
There's also a bit of trickery you can do since ColdFusion (by default) ignores empty list elements:
<cfset myList=arrayToList(listToArray(myList))>
Heck, even this'll work:
<cfset myList=listChangeDelims(myList , "," , ",")>
Of course, if you're not outputting the list as a string, you don't need to worry about that comma on the end since ColdFusion will just ignore the empty element. If you are outputting it as a string, here's yet another way to clean up that comma. It's not as reliable as the others, though.
<cfoutput>#left(trim(mylist),len(trim(mylist))-1)#</cfoutput>
What do you use? Replace() linebreak chars with <br>? what about spaces? like maybe replace 2 spaces with ?
ParagraphFormat() sucks.
paragraphformat2()? http://www.cflib.org/udf.cfm/paragraphformat2
ReplaceNoCase(someString, "\n", "<br>","all")
One thing you may have to take into account is that different OS treat line breaks differently. Windows uses CR/LF while OS X and Unix use CR. I have used a code block effectively in the past to manage the different possibilities when it comes to reading in text files. Same principles could apply here. It's not 100% perfect, but on the rare occasions it has failed me it was because of an odd method of how the file was created. I modified it to fit the general idea of what you are going after.
<cfset variables.CRLF = findnocase(variables.textFromTextarea,"#chr(10)#") />
<cfif variables.CRLF>
<cfset variables.textFromTextarea = replaceNoCase(variables.textFromTextarea,"#chr(10)#","<br>","all") />
<cfelse>
<cfset variables.textFromTextarea = replaceNoCase(variables.textFromTextarea,"#chr(13)#","<br>","all") />
</cfif>
The idea here is that you are looking for the windows-only LF. If found, replace on it. Otherwise replace on the CR. Maybe that will work for you.
I needed to replace text from a textarea input to html when output on a webpage, and preserved the line break. So based on the accepted answer, I simply modified it to this, and it worked:
ReplaceNoCase(someString, Chr(10), "<br />","all")
Hope that helps anyone else.
