[R] Memory getting eaten up with XML

Hi all. I have an issue that I cannot resolve. I am trying to read in lots of data that are stored in xml files. But after I read them in and copy the relevant data, then remove the document etc, it doesn't free up the memory. When I monitor it in windows task manager the memory usage just climbs with each iteration until R crashes. I can replicate the problem with the small example:
xx <- xmlRoot(TEMPP)
Even though I remove the root node xx and the document TEMPP, the memory usage remains the same as it was when I first read it in... Any ideas/solutions?
I am using a 32bit version of R 2.14.0 on windows XP, and the latest version of XML (3.6.1).
