r - GET {httr} returns a Bad Request response -

-

i trying scrape html elements of url stored insearchlink. method worked me ishtmltreeparse {xml}.however it's not returning elements i'm looking for. example:img[@title='add compare'] 

searchlink <- "http://www.realtor.ca/map.aspx#cultureid=1&applicationid=1&recordsperpage=9&maximumresults=9&propertytypeid=300&transactiontypeid=2&sortorder=a&sortby=1&longitudemin=-114.52066040039104&longitudemax=-113.60536193847697&latitudemin=50.94776904194829&latitudemax=51.14246522072541&pricemin=0&pricemax=0&bedrange=0-0&bathrange=0-0&parkingspacerange=0-0&viewstate=m&longitude=-114.063011169434&latitude=51.0452194213867&zoomlevel=11&currentpage=1"   doc <- htmltreeparse(searchlink,useinternalnodes = t)      classes <- xpathsapply(doc,"//img[@title='add compare']",function(x){xmlgetattr(x,'class')})

the result of running classes above:

list()

i have tried readlines , get {httr} both returned error in reading url. guessing it's because of special characters in url don't know how go fixing it. response given below:

try removing 1 # in url, replaced ?

library("httr") url <- "http://www.realtor.ca/map.aspx?cultureid=1&applicationid=1&recordsperpage=9&maximumresults=9&propertytypeid=300&transactiontypeid=2&sortorder=a&sortby=1&longitudemin=-114.52066040039104&longitudemax=-113.60536193847697&latitudemin=50.94776904194829&latitudemax=51.14246522072541&pricemin=0&pricemax=0&bedrange=0-0&bathrange=0-0&parkingspacerange=0-0&viewstate=m&longitude=-114.063011169434&latitude=51.0452194213867&zoomlevel=11&currentpage=1" res <- get(url) tt <- content(res)
