Hi, Why is the following retuning a nodset of length 0: > library(XML) > test <- xmlTreeParse( > "http://www.unimod.org/xml/unimod_tables.xml",useInternalNodes=TRUE) > getNodeSet(test,"//modifications_row") Thanks for any hint. Joh

...know that the html code is malformed, but for my purposes i can ignore that output. Is there a way to achieve this? ### Example: library(RCurl); library(XML) doc <- getURL('http://www.google.co.uk/search?q=%22R%20Project %22&as_qdr=d1&num=100') html.tree <- htmlTreeParse(doc, useInternalNodes = TRUE) ### Output - this is what i would like to suppress Tag nobr invalid htmlParseEntityRef: expecting ';' htmlParseEntityRef: expecting ';' ### etc. I attempted to use try(expr, silent=TRUE) but that didn't work for me: > try(htmlTreeParse(doc, useInternalNodes = TRUE...

I would like to track in which journals articles about a particular disease are being published. Creating a pubmed search is trivial. The search provides data but obviously not as an R dataframe. I can get the search to export the data as an xml feed and the xml package seems to be able to read it. xmlTreeParse("

...ry large, I mean going up to 5-10Gb, although I am using a 'small' 40M file to test my code.) My first attempt at parsing the 40M file, using the XML package, took more than 2200 seconds and left me quite disappointed. I managed to cut that down to around 40 seconds by: -using the 'useInternalNodes' option of the XML package when parsing the xml tree; -vectorizing the parsing (i.e., replacing loops like "for(node in group.of.nodes) {...}" by "sapply(group.of.node, function(node){...}") I gained another 5 seconds by making small changes to the functions used (like...

Dear all, for my diploma thesis I have to import huge XML-Files into R for statistical processing - huge means a size about 33 MB. I'm using the XML-Package version 1.9 As far as reading the complete file into R via xmlTreeParse doesn't work or is too slow, I'm trying to use xmlEventParse but I got completely stuck. I have many different type of nodes + <configuration>
