How do I use a regex or other pattern match in a Confluence Velocity Macro Template

Question

I want to use a regex to test a string in a macro #if. I can't find a string method that will test a regex. #if($labelName.match('.*')) $label #end

@Dominic Lagger , thank you for the hint. I had tried something similar initially but couldn't get the .matches() method to work. When I saw your suggestion, I dug a little deeper and realized that I wasn't getting the .matches() method because my variable was of class com.atlassian.confluence.labels.Label, not a Java String. Once I added a .getName() method, I got a String and things worked as hoped. #foreach ( $labelling in $page.getLabellings() ) #set( $label = $labelling.getLabel().getName()) #if( $label.matches($paramFeaturedLabels) ) $label #end #end

Hi @Hugh Kelley Could not test it, but java gives the Matcher Class. Can you try with this? #set($regex = ".*") #set($matcher = $regex.matcher($labelName)) #if($matcher.matches()) $label #end Regards, Dominic
