[R] retrieve certain part from html

[Romain Francois]

Hi,

The R4X package can help you. (I have wrapped your td's into one tr)

 > x <- xml( "<tr><td><a href='2005-01.html'>2005-01</a></td><td><a
+ href='2006-01.html'>2006-01</a></td><td><a
+ href='2007-01.html'>2007-01</a></td><td><a
+ href='2008-01.html'>2008-01</a></td><td><a
+ href='2009-01.html'>2009-01</a></td></tr>" )

 > x["td/a/#"]
        td        td        td        td        td
"2005-01" "2006-01" "2007-01" "2008-01" "2009-01"
 > x["td/a/@href"]
             td             td             td             td             td
"2005-01.html" "2006-01.html" "2007-01.html" "2008-01.html" "2009-01.html"
