Is there any function to write a XML structure, after it was read using xmlTreeParse? Ex: library(XML) x <- xmlTreeParse("Irpf2008/aplicacao/dados/12345678901/12345678901.xml") # write it... Alberto Monteiro PS: please, brazilians, don't be offended by my foul language!

...ome elements and store everything back as an XML document. I've tryed the following: doc <- xmlTreeParse("file.xml") QTListNode<-xmlElementsByTagName(xmlRoot(doc)[[1]],"tagname") append.xmlNode(QTListNode[[1]],newXMLNode(name ="Norm", attrs = NULL)) saveXML(doc, file = "out.xml", compression = 0, indent=T) This doesn't seem to work. Can anyone help? Thanks, Steffen

I'm probably being dense but I can't work out how to add the second line: <?xml version="1.0" encoding="ISO-8859-1"?> <?xml-stylesheet type="text/xsl" href="style.xsl"?> <catalogue> ... ... I can get the first line using: saveXML(xml$value(), prefix='<?xml version="1.0"?>', encoding="ISO-8859-1") Any ideas? Thanks.

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("

Hi all, I have again noticed that the wiki does not really show up in search results and wonder if it has any impact that robots.txt on wiki.centos.org is empty. Perhaps it should at least contain User-agent: * ? Best Regards Marcus

I would like to learn how to parse a mixed text/xml document I downloaded from the sec.gov website (see example below). I would like to parse this to get the value for each xml tag and then access it within R, but I don't know much about xml so I don't even know where to start debugging the errors I am getting in this example code. Can anyone help me get started? Thanks, Roger ftp

Hi, I am working on developing a web crawler in R and I needed some help with regard to removal of javascripts and style sheets from the html document of a web page. i tried using the xml package, hence the function xpathApply library(XML) txt = xpathApply(html,"//body//text()[not(ancestor::script)][not(ancestor::style)]", xmlValue) The output comes out as text lines, without any html

Dear Listers: I have a couple of data frames to report and each corresponds to different condtions, e.g. conditions=c(10, 15, 20, 25). In this examples, four data frames need to be exported in a "pretty" report. I knew Perl has some module for exporting data to Excel and after googling, I found R does not. So I am wondering if there is a package in R for generating good reports. I

Dear all I am trying to use the ODB package to connect to an libreoffice-odb database. The libreoffice package is german, thus, decimal separator is a comma.
