Regular expression to replace tags

Does anyone have a regular expression that will remove any tag and the content between the tags and replace it with the blank tag value? For instance if I want to remove the "<head></head>" tags and any character and/or nested tags between them and replace them with "<head><title>My Title</title></head>".

You could do it in two steps.

Step 1) Replace <head>....</head> with <head></head>

You could use a regular expression similar to:
<head>*</head>

Step 2) Then you can replace <head></head> with what you want using a simple replace.

You could probably combine into one step, up to you.

Ok, that didn't work. When I ran that example the page "<HEAD></HEAD>" tags were not removed and the content in between them was not removed of which there is a ton (javascripts, meta tags etc.).

Here is the code I was running:

<CFTRY>
<cfhttp method="get" url="http://www.someurl.com" resolveurl="yes">
</cfhttp>
<CFCATCH>
<CFSET ThrowError = true>
</CFCATCH>
</CFTRY>
<cfset ApScriptEdit = #ReReplaceNoCase(cfhttp.FileContent, "<head>*</head>", "", "ALL")#>
<Cfoutput>#ApScriptEdit#</Cfoutput>

Hi

Almost there try this:

<cfset ApScriptEdit = rereplacenocase(cfhttp.FileContent, "<head>.*?</head>","","ALL")>

Whoops. Probably want to remove the htmlCodeFormat() from that output, was doing that for debugging.

Works great, just what I was looking for.

It looks so simple when I see the solution but some how I never seem to get the regular expressions right.

Thanks for the help!
