Parsing XML in Mappers

[ywen2000ge]

I need to parse some XML files into structured format. I set the input format of the mapper as make.input.format("text"). I used the following sample code. The XML library was correctly loaded. The issue is that one xml file was split to multiple mappers and the input to each map is no long in valid xml format. I am wondering if there is a way to force one mapper to process an entire file. Typical file size is around 1MB.

Also how do I make the input loaded as one string? Now the file is loaded to be a vector with each element being a row of the file. That's why I had to collapse it before parsing. Any better way?

mapper <- function(.,value)
{
value <- paste0(value,collapse=''")
doc <- xmlTreeParse(value)
...
}

Thank you!
