    You can extract the a elements and call xmlGetAttr on them.

    library(RCurl)
library(XML)
script <- getURL("www.r-bloggers.com")
doc <- htmlParse(script)
li <- getNodeSet(doc, "//ul[@class='xoxo blogroll']//a")
sapply(li, xmlGetAttr, "href")

    You can also use xpathApply directly:

    xpathSApply(doc, 
  "//ul[@class='xoxo blogroll']//a", 
  xmlGetAttr, "href"
)
