CSS element locator

According to your markup (and if I understand you correctly), this is the selector that you would need:

.pickup.ng-binding > i:first-of-type

Right now, you're selecting everything in .pickup.ng-binding'. What you appear to want is to use the attribute first-of-type to get the first i, which is in this case 26 Todman Ave Kensington.

Edit: I just saw that "26 Todman Ave Kensington" is not wrapped in the i class="fa fa-map-marker. Now your question has rendered me utterly confused.

I think you could try to wrap the first line with a <p>tag. So you could select them by using .pickup.ng-binding > p

You're trying to get one of the child text nodes inside dd.pickup.ng-binding, which is not in an i element but directly in the dd element. This cannot be achieved directly using just a CSS selector since selectors only look at element nodes, not text nodes. You could just select the dd itself like you have done, but you will need to getText() and then parse it and extract just the portion you need, which is cumbersome.

I recommend using XPath instead which allows you to select individual text nodes directly without having to worry about parsing what might be arbitrary text:

driver.findElement(By.xpath("//dd[@class='pickup ng-binding']/text()[1]"));

Depending on what the actual markup looks like (what you have is a DOM tree view), if text()[1] doesn't get you anything it's probably inter-element whitespace; try text()[2] and so on until you find the text that you need.
