OK - this is a fine candidate for 'how many ways can it be done?'. My
contribution [NB untested]:
http://waterdata.usgs.gov/ny/nwis/uv?format=rdb&period=1&site_no=01420500

$current = $content{count($content)-2};
Use count to find the number of elements and use count-2 to select the
second-to-last element. Recall that the first element is [0].
