Question

I'm looking to scrape some Houston Dynamo stats from this season into a CSV and then visualize that data with R.

How can I scrape both the tr and td elements using lxml? Is there an easier selector I should be looking at?

Answer 1

For (reasonably) well formed HTML tables, the XML package in R makes this sort of thing pretty stupidly easy:

library(XML)
> url <- "http://www.houstondynamo.com/stats/season?page=0"
> tbl <- readHTMLTable(url)
> head(tbl[[1]])
