// get the lyrics page. Rhino readUrl() method is particularly
// convenient.
var rawLyrics = readUrl("http://99-bottles-of-beer.net/lyrics.html");
// the html lyrics page (http://99-bottles-of-beer.net/lyrics.html)
// is not well-formed, so we have to replace <br> with <br/>
var wellFormedRawLyrics = rawLyrics.replace(/<br>/gi, "<br/>");
var xmlLyrics = new XML(wellFormedRawLyrics);
// set the default namespace for convenience--don't hardcode
default xml namespace = xmlLyrics.namespace();
// First, we look for any elements in the page that contains an element
// whose text starts with "99 bottles of beer".
var songVerses = xmlLyrics..*.(/^99 bottles of beer/.test(p.text()));
// Then we print each verse, adding newlines as necessary
for each(var verse in songVerses.children()) {
var verseText = verse.text().toString().replace("\.", ".\n");
print(verseText + "\n");
