Very simplistically remove HTML tags from strings.

gistfile1.java

public static String stripTags(String input) {
    return input.replaceAll("\\<.*?>","");
}

stripTags.groovy

// In Groovy we can add a stripTags method to the String class:
String.metaClass.stripTags() {
    delegate.replaceAll("<(.|\n)*?>", '')
}

stripTags.js

String.prototype.stripTags = function() { return this.replace(/<.+?>/g, ''); };
