quick and dirty hack to get the discography list from an artist in wikipedia :D

discograph-qtip.js

var _       = require('underscore')._;
var casper  = require('casper').create({
    clientScripts: [
        'bower_components/jquery/dist/jquery.min.js',
        'bower_components/underscore/underscore.js'
    ],
    verbose: true,
    logLevel: 'debug'
});

casper.start('http://en.wikipedia.org/wiki/Q-Tip_(musician)', function() {
        var discographyList = this.evaluate(function() {
            var k = /(d|D)(iscography)/g; // quick and dirty
            var contentText = $('#mw-content-text');
            var headlines = $('h2', contentText);
            var matchingHeadline = _.find(headlines, function(headline) {
                return headline.innerHTML.match(k);
            });

            var table = null;
            if (matchingHeadline) {
                matchingHeadline = $(matchingHeadline);
                var next = matchingHeadline.next();
                while (next) {
                    if (next[0].nodeName.toLowerCase() !== 'ul') {
                        next = next.next();
                    } else {
                        table = next;
                        next = null;
                    }
                }
            }

            var discos = [];

            if (table) {
                var childElements = $('li', table);
                _.each(childElements, function(element) {
                    discos.push($(element).text());
                });
            }

            return discos;
        });

        utils.dump(discographyList);
    });

casper.run();
