You can use the XML package to parse the page and extract the contents
of the table:
index <- "^DJI"
url <- paste("http://uk.finance.yahoo.com/q/cp?s=", index, sep="")
symbols <- readHTMLTable(url, as.data.frame=FALSE)[]$Symbol
You should check the size of the result: large indices may be split
across several pages, and the layout of the page may change.
