First you need to identify the <span>
element and then get the text node right after it. Since your span elements don't have anything unique, you can use the order they're found in the parent element to identify them.
You can use pseudo-selectors such as :first-child
or :nth-child
to do so.
Once you've identified the span, you need to select the next node and retrieve its value.
One example:
console.log($('span:first-child')[0].nextSibling.nodeValue)
