I suck at regexes. I know there has to better regex for extracting all the values for a particular attribute from an of HTML string.

gistfile1.js

function getAttributeValues(html) { 
    var htmlSubstr = html,
        match = true,
        values = [],
        start = 0;

    while (match) {
        htmlSubstr = htmlSubstr.substr(start);
        match = htmlSubstr.match(/<[^>]*\s(?:some-attribute-name=["']([^"']*)["'])[^>]*>/);
        if (match) {
            values.push(match[1]);
            start = match[0].length + match.index;
        }
    }

    return values;
};
