Hi! I would start by looking at "A Short Introduction to the XML package for R". The xPath part of the document seems relevant to your problem. http://www.omegahat.org/RSXML/shortIntro.html I'm not exactly sure of what you are trying to do, but here's a start: foo <- xmlInternalTreeParse("yourfile.xml") nodes <- getNodeSet(foo, "//node[@id]") sapply(nodes, xmlGetAttr, "id") sapply(nodes, xmlValue)
