Feeling Groovy: Quick Summary of a Jersey WADL

I have a Jersey based REST service and just needed a quick API summary. Groovy to the rescue! After grabbing the WADL (http://(whatever your context is)/application.wadl) I simply fed it to this little script. I am sure it could be improved to get the WADL itself, or read from stdin (which would be more Unix like) etc…


#!/usr/bin/env groovy
if (!this.args) {
System.err.println "usage summarize_wadl <wadl file> "
return -1
}

def s = [];
def nodes = new XmlParser().parseText(new File(this.args[0]).getText())
nodes.resources.resource.resource.each {
s << "${it.method.@id} => ${it.method.@name} => ${it.@path}"
}
s.sort().each { println it };
return 0

Got a better way? Faster way? More Groovy-o-matic (idiomatic) way? Teach us all! Leave a comment. I'll credit and incorporate ideas if allowed.
