Here we take a node and extract the match. Note that we have to call first on the result of <code>html/select</code> because <code>html/select</code> always returns a sequence of nodes and not a single node. <code>zipmap</code> is a handy function, it allows us to take two sequences and zip them up into a hash-map.
