// Extract every other digit from a string using XRegExp.forEach
XRegExp.forEach('1a2345', /\d/, function(match, i) {
    if (i % 2) this.push(+match[0]);
}, []); // -> [2, 4]

// Get numbers within <b> tags using XRegExp.matchChain
XRegExp.matchChain('1 <b>2</b> 3 <b>4 a 56</b>', [
    XRegExp('(?is)<b>.*?</b>'),
    /\d+/
]); // -> ['2', '4', '56']
