Re: More Complicated RegEx Replace
This is the replace statement a regex guru gave me
to wrap a variable found in a string in a span tag.
Not sure you can call them a guru when the only piece of regex used is a pair
of parentheses which are entirely unnecessary. *shrug*
Here's a simpler version that does exactly the same thing:
REReplaceNoCase
( answer
, search_string
, 'span class=keyword\0/span'
, 'all'
)
However, what that isn't doing is escaping potential regex metacharacters
inside search_string (which could then result in unexpected behaviour).
If you can't guarantee there will not be any metacharacters present, you need
to do this:
REReplaceNoCase
( answer
, search_string.replaceAll('[$^*()+\[\]{}.?\\|]','\\$0')
, 'span class=keyword\0/span'
, 'all'
)
(Which prefixes the relevant characters with a backslash to escape them.)
Anyhow, as for your actual problem, regex is not a good tool for parsing HTML
(which is what you're asking to be done by excluding tag attributes from
matching).
What you need to do is use a HTML parsing library, such as jSoup, to isolate
the text segments within HTML tags, and loop through performing your replace
operation on each of those in turn (recursing down through any child tags as
required).
Using jSoup, this can be achieved with the textNodes() method, to access the
individual segments of text and child nodes:
http://jsoup.org/apidocs/org/jsoup/nodes/Element.html#textNodes()
If you're unfamiliar with using JARs in CF, Ben Nadel has a post on using jSoup
with CF10:

QUESTION IS, how do I call the makeSound() method in the feline object

I am told it is possible but I have not been able to find out exactly

I did read you need to pass a type reference to it but not sure what that

Re: Replace Question
This is a case for Regular Expressions (RegEx):
REReplaceNoCase(answer, '(#search_string#)', 'span
class=keyword\1/span', 'all')#
Heh, just seen this after the other thread, so guess I'll repeat what I said
there:
Using parentheses is completely unnecessary. Use \0 in the replacement string
instead.
If search_string is (for example) $10 or :) or a+b^c or whatever then
simply using it as a regex_pattern will cause problems.
To solve this means escaping the meta-characters, for example,
search_string.replaceAll('[$^*()+\[\]{}.?\\|]','\\$0')
Putting both those together results in:
REReplaceNoCase
( answer
, search_string.replaceAll('[$^*()+\[\]{}.?\\|]','\\$0')
, 'span class=keyword\0/span'
, 'all'
)
(Though of course, as noted in the other thread, this doesn't deal with HTML.)

Remember though - when you call a CFC in CF7, it will either be encoded in WDDX by default. That's why I said you probably want to call a CFM instead. The CFM calls your CFC, gets the result, serializes it, and outputs the JSON. My memory is a bit vague here, but if I remember right... CF6 let you call CFCs via AJAX, but you ALWAYS got WDDX back. CF7 let you get WDDX or use returnformat=plain to NOT do any translation on the result. So... actually - and I hope this isn't too confusing now. Your CFC should return qry_Metric as defined above. Your URL, the one you use in Ajax, should include returnformat=plain to tell CF Dude, don't do anything to my result. When your CFC returns the string (JSON is a string), it should be left alone then. -- === Raymond Camden, Adobe Developer Evangelist Email : raymondcam...@gmail.com Blog : www.raymondcamden.com Twitter: cfjedimaster ~| 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:351788 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm

Presumably, the feline object already extends the makeSound method of the animal object, right? Why wouldn't you just have the cat object extend the makeSound method of the feline object? Why would you want to skip a generation, so to speak? That seems like it would be poor design.

viewport tag question
My apologies for the non-CF related question (though the site is running on CF), but I know folks here are so well-rounded I'll throw it out. I'm struggling with getting a site to scale correctly on mobile devices. I have tried the viewport tag with various settings, but don't really understand the tag that well. The current code has this: meta name=viewport content=width=960, initial-scale=1, maximum-scale=1 I have tried setting the width=device-width and it didn't seem to help. Site in question: http://amaproracing.com/ In portrait mode on whatever device (seems consistent across various phones and tablets), it loads with only a portion (30%?) of the width showing. You can pinch the screen to zoom out and get the entire site. Landscape mode seems to be ok for most devices. Does anyone have a solid understanding of how to set the viewport tag up so it is good in both portrait and landscape orientations?

Re: 500 - Internal server error
RightOn you guys! Turns out that both Justin and Michael's tips were successful... either or both of the switches together made the the cferror routine that we built run properly. Yes! and Thank You! Now as for Carl's parameter limit... don't know how that might be useful unless of course we run into this again and have a zillion parameters being passed to CF ;-) I would think we would want to pass the typical IIS errors and check that in the CFAdmin settings... but it is clearly not necessary. However we do have it checked in all our other installs... both Windows and Linux and all is well everywhere except with this new install... which is apparently fixed now. So this brings up the question now of what's the full purpose of the CFAdmin setting and it's use with the IIS setting for Details vs Custom IIS error pages? Thanks!

Re: 500 - Internal server error
... So this brings up the question now of what's the full purpose of the CFAdmin setting and it's use with the IIS setting for Details vs Custom IIS error pages? Basically IIS is looking at the response codes from an application and when it sees anything other than normal 200 (OK) code (and some others, such as 30X redirects), it will look at the error handling settings to see how it should respond to the user. If the custom errors are enabled for the visitor in question, then it will use whatever is set in the IIS settings (e.g. display a static HTML file, a generic error code, redirect to a page, etc.). This is to prevent any sensitive information from leaking out of the server in the case of an error (such as the info that would normally come from a robust error handling exception in ColdFusion). IIS is helping to protect the security of the application and handle error conditions for you. The setting in the CF admin controls what status code is sent out when there is an error. Normally when CF encounters an error it will send a 500 (Internal Server Error) code which IIS then intercepts and handles as described above. If you change this setting, you can have CF send a 200 (OK) code even in the event of an error which bypasses the IIS error handling routines and allows whatever output CF generates (page, error page, custom error handler output, etc.) to get through just like any other regular content. IIS just sees it as a normal response at that point and allows it through. -Justin ~| 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:351795 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
Re: 500 - Internal server error
for CF sites it should be fine to simply enable errors in IIS as all your errors are going to be returned by CF anyway. The only exception would be if your running a mixed site with CF and other technology. In which case as long as you separate your technologies into different folders, you can put a web.config into each folder with different settings. So CF could have errors enable and asp.net disabled for example. Or you could simply create a custom error on IIS and have that displayed instead. have you tried using the sitewide error template in CF, I don't think that causes the server 500 error.
