Parse string in javascript using regular expressions

I have html fragment on my page and it looks like this: 

...
    <address>
       6231 Leesburg Pike Ste 100A<br>
       Falls Church, VA 22041-2102
    </address>
...

How can I parse this string using jQuery to get data below:

1. Address: 6231 Leesburg Pike Ste 100A
2. City: Falls Church
3. State: VA
4. ZIP: 22041

Thanks!

Regex:

(.*)\n(.*?),\s([A-Z]{2})\s(\d{5})

Javascript:

var str = $("address").text()
var extract = str.match(/(.*)\n(.*?),\s([A-Z]{2})\s(\d{5})/);

var address = extract[1];
var city = extract[2];
var state = extract[3];
var zip = extract[4];

console.log(address) // 6231 Leesburg Pike Ste 100A
console.log(city)    // Falls Church
console.log(state)   // VA
console.log(zip)     // 22041
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<address>
6231 Leesburg Pike Ste 100A<br>
Falls Church, VA 22041-2102
</address>

Most pragmatic, assuming no other commas in the state/zip - much easier to read and more maintainable than a oneliner regexp

jQuery is only used to get and set the HTML - innerHTML can be used to not need jQuery at all

$(function() {
  var addr = $("address").html(),
    parts1 = addr.replace(/\s+/g, " ").split(/<br>/i),
    parts2 = parts1[1].split(","),
    parts3 = parts2[1].trim().split(" "),

    address = parts1[0].trim(),
    city = parts2[0].trim(),
    state = parts3[0].trim(),
    zip = parts3[1].trim(); // spirit on - if you need first part only 
  $("ol").after("<ol><li>Address: "+address+
     "</li><li>City: "+city+
     "</li><li>State: "+state+
     "</li><li>Zip: "+zip+"</li>");
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<address>
       6231 Leesburg Pike Ste 100A<br>
       Falls Church, VA 22041-2102
    </address>

<ol>
  <li>Address: 6231 Leesburg Pike Ste 100A</li>
  <li>City: Falls Church</li>
  <li>State: VA</li>
  <li>ZIP: 22041-2102</li>
</ol>

<address>[^\d]*(\d{1,4}[^<,]*)(?:<br\/?>|,)\s*([^,]*),\s*([A-Z]{2})\s*(\d{3,5})[^<]*<\/address>

Breakdown

<address> = start anchor
[^\d]* = eat all non digits
(\d{1,4}[^<,]*) Capture address
(?:<br\/?>|,)\s* eat to a <br> or comma
([^,]*) = Capture city
([A-Z]{2}) = capture state code
(\d{3,5}) = capture zip
[^<]* = eat rest too anchor
<\/address> = end anchor


var str = "<address>\
   6231 Leesburg Pike Ste 100A<br>\
   Falls Church, VA 22041-2102\
</address>";
console.log(str.match(/<address>[^\d]*(\d{1,4}[^<,]*)(?:<br\/?>|,)\s*([^,]*),\s*([A-Z]{2})\s*(\d{3,5})[^<]*<\/address>/))

    console.log(`<address>
           6231 Leesburg Pike Ste 100A<br>
           Falls Church, VA 22041-2102
        </address>`.match(/(\d+.*)<br>\n\t?(.*), (\w+) ([\d-]+)/))

No jQuery needed
