Using string replacement ($& and $+) with findReplaceRegex (Confluence CLI tool)

Maarten van Hee

Hello!

I've been using CLI for a few days now and it has greatly sped up the wiki migration i'm doing. Today i've been doing a lot of findReplace and findReplaceRegex to replace common things throughout very similiar articles, but i ran into a little problem wich i can't seem to figure out.

What i'm trying to achieve is this: i need to find strings that start with '@' and have all capital letters and then, with the match, i want to put <span class='myclass'> </span> around it to get some simple syntax highlighting. I'm not a big expert on regular expressions, but from what i can remember shouldn't it be possible to use string replacement on the right hand part of the findReplaceRegex action call parameter in order to re-use the matched string?

I've found this example at the documentation:

--findReplaceRegex "(a )(test)(.*):\$1\$3#\$2#"

Which seems to be doing something similiar to what i want, using the matched strings again to replace the existing ones. However, i can't get this to work. When i do it like this it just prints \$1\$3#\$2# as string in my article.

Any idea if it's possible to get it working? Would again be a great time saver. This is what i have so far:

--findReplaceRegex "(@)([A-Z)$&"

Thanks in advance!

1. It helps a lot to get your regex working using this tool: http://www.regexplanet.com/advanced/java/index.html
2. You need to watch out for special characters (command line and regex) - it can get confusing when you have to escape things and it depends on your OS what needs to be escaped (the example \$ is an escaped $ on unix)
3. Quick look at your regex shows a few problems
   1. Don't you want [A-Z]* ? You are missing the closing ] and the * (0 or more characters)
   2. You need $1 on the replace
   3. I suspect you need some like:

      (@[A-Z]*):some text\$1some other text
