yes, should be as easy as this:

 library(XiMpLe)
 # parse the .pluginmap
 some.plugin <- parseXMLTree("<path_to>/some.pluginmap")
 # extract the <component> nodes, returns a list
 some.plugin.comp <- XMLScan(some.plugin, "component")
 # get the values of all "file" attributes
 sapply(some.plugin.comp, function(x) XMLAttrs(x)[["file"]])

this could be condensed into a one-liner, but then it's harder to read ;-)

some things to be aware of: parseXMLTree() might either abort or produce 
rubbish if the .pluginmap includes erroneous XML (e.g., a missing "/" or an 
invalid "&"), even if RKWard gracefully ignores it. see that as a bug tracking 
feature ;-) also, i've just commited a new boolean argument to XMLScan(), 
"as.list", because if there's exactly one result, it will directly return the 
single XiMpLe node, not a list of length one. the latter can now be forced by 
"as.list=TRUE" -- but this shouldn't matter here, i guess.
