Yes. I have noticed that there two sorts of xml that pubmed will
provide. The kind I had hooked into was an rss feed which provides a
lot of the information simply as a formatted table for viewing in a
rss reader. There is another way to get the xml to come out with more
tags. However, I found the best way to do this is probably through the
bioconductor annotate package
x <- pubmed("18046565", "17978930", "17975511")
a <- xmlRoot(x)
numAbst <- length(xmlChildren(a))
absts <- list()
for (i in 1:numAbst) {
absts[[i]] <- buildPubMedAbst(a[[i]])
}
I am now trying to work through that approach to see what I can come up with.
