'externalptr' error in R using XML data
The XML package works by making pointer document of the XML document your trying to manipulate.
The 'externalptr' are simply external pointers to the data within the xml document.
To access the data you need to use
Parsed.xml <- xmlTreeParse(xml) ## should be string with xml text## get value of the first nodexmlValue(xml[[1]])## get value of the third grandchild of the first nodexmlValue(xml[[1]][[45]][[3]])
You need to access each node of the xml as a list.
