I'm tryig to scrape an specific location of a web page using XPath to find it. 
The path seems to be "hidden" as other parts of the web page are easily reachable, but this section returns a `NULL` value.

I've tried using several packages, but i'm really not an expert in the subject so i can't really assess what's going on and if the is a way to solve it.

This is what i've tried.

```
require("XML")
require("scrapeR")
require("httr")

url <- "http://www.claro.com.ar/portal/ar/pc/personas/movil/eq-new/?eq=537"
xp <- '//*[@id="dv_MainContainerEquiposResumen"]/div[1]/h1'

page <- scrape(url)
xpathApply(page[[1]], xp, xmlValue)
# NULL

url.get = GET(url)
xpathSApply(content(url.get), xp)
# NULL

webpage = getURL(url)
doc = htmlTreeParse(webpage, error=function(...){}, useInternalNodes = TRUE)
xpathSApply(doc, xp)
# NULL

```
