xml to R dataframe

I am trying to store all the data in the below xml file as 1 or numerous data frames in R. So far, only able to parse the first SubCategory and store it in a df. Would like to store all the further data in the xml file in 1 or numerous dataframes - whichever is an easier solution. Any suggestions?

My code:

library(XML)
data<-xmlParse("http://advisory.mtanyct.info/LPUWebServices/CurrentLostProperty.aspx")
xml_data <- xmlToList(data)
SubCategory<- data.frame(as.list(xml_data[["Category"]][["SubCategory"]]))

Try xmlAttrsToDataFrame

x <- lapply(data["//Category"], XML:::xmlAttrsToDataFrame)
names(x) <- xpathSApply(data, "//Category", xmlGetAttr, "Category")
library(plyr)
ldply(x, data.frame, .id="Category")
           Category              SubCategory count
