If you notice at Google main page, there is a link called "more" right at the top, and the down arrow key is next to it, which is reflected in the ruby output as
Code:
-->http://www.google.com/intl/en/options/, more »

The down arrow key is itself a url link.

Thanks Kurumi, it was because of event definitions in the tag.
Code:
awk -F'>' '/[ \t]href=/{N=split($1,F,"\""); i=1; while(F[i++]!~/[ \t]href=/); print F[i],$NF}' RS='<'

This because there are underline tags with angular brackets in the description. I give up without a library Smilie
