Comment on ColdFusion using Java for regex replace by Jake Churchill

Thanks for the comments. The backreferencing is the exact reason I dropped back to Java for this. I did not know to use a “\1″ instead of a “$1″.

The Java regular expression engine (that you are accessing) is definitely awesome. It’s faster and more robust that the one exposed by ColdFusion (POSIX). That said, ColdFusion’s reReplace() should be able to handle this as well; you just have to be careful because the back-references use “\N” rather than “$N” notation.

Hmmm. The tags have been broken in that post - I’ll repost with them replaced by {braces}

I’m confused - you’re not using anything Java regex here - you can do everything here with CF!

{cfset contentVariable = rereplace( contentVariable , ’src=”(/.+?)”‘ , ’src=”#domainName#\1″‘ ) /}

Though you could of course have used Java’s lookbehind and possessive quantifiers, for something that is (potentially) very slightly better performance, like so:

{cfset contentVariable = contentVariable.replaceAll( ‘(?<=src=”)/[^"]++’ , ‘#domainName#$0′ )/}

But this is still using Regex to parse HTML, which has a number of pitfalls. The ideal method is using a DOM parser instead.

The ideal way is to use a DOM parser instead. (The best we’ve got for CF is XmlParse, which isn’t great; there are Java DOM parsers which I keep meaning to check out but haven’t got around to yet.)

I’m confused - whilst its useful for people to know they can use Java String functions - you’re not using anything that requires Java regex here - you can do everything you did with regular CF!

Here’s an example that uses Java’s lookbehind and possessive quantifiers, for something that is (potentially) very slightly better performance, like so:

I’ll try again:

>cfset contentVariable = ReReplace(contentVariable,’src=”(\/.+?)\”‘, ’src=”#domainName#\1″‘,’all’) /<

Hi Jake

Why not just use the ColdFusion ReReplace() function like below?

Cheers

Do you get this intermittently (the HTTP Failed:) or consistently everytime ?
