您可以尝试这样（使用 httr 包）。

You could try something like this (using the httr package).

# this is just to create a file with xml content - you have this already
library(XML)
txt <- '<?xml version="1.0" encoding="UTF-8"?><doc><item>text</item><item>text</item><item>text</item></doc>'
out2 <- "myfile.xml"
saveXML(xmlTreeParse(txt,useInternalNodes=T),out2)

# you start here...
library(httr)
POST(url='http://211.211.211.211:27844/ssentsvc',
     body=upload_file(out2),
     config=add_headers(c('SOAPAction'='"http://google.com"', 'Content-Type'='text/xml')))
