how to handle errors while reading xml files R

I have a list of multiple xml files which have the same structure. Some of them have structural errors in them so they can't be read, i'm not capable of controlling them manually because there are too many files. I know that i need to imply the try or trycatch functions, i tried to understand them but i'm not understanding how to use them proberly on my case. To make the example easy i just want to transform them all into a csv.

library(XML)
k <- 1
Initial.files<- list.files("/My/Initial/Folder")
for(i in initial.files){
data<-dataTable(xmlToDataFrame(xmlParse(i)))
write.csv(data, file = paste("data",(k)".csv"))
k <- k+1
}

The error i get usually looks like:

Start tag expected, '<' not found
Error in xmlToDataFrame(xmlParse(i)) :
error in evaluation the argument 'doc' in selecting a method for function 'xmlToDataFrame': Error 1: Start tag expected, '<' not found

To handle my problem i have to rewrite my 5th line of code(i know that it is wrong):

data<- if(try(dataTable(xmlToDataFrame(xmlParse(i)))!= "try-error")
else{ haven't looked close to this because i didn't got that far...}...

I would like it to read the files and give me a list of the files path which didn't work to be read.
