pmcOAI: Download Open Access articles from PMC

In cstubben/pmcXML: Tools to parse full text XML documents from PMC Open Access

Description

Download and save XML documents from the PMC OAI service

Usage

pmcOAI(id, local = TRUE, dir = "~/downloads/pmc", ...)

Arguments

id	PMC id
local	use local copy if available
dir	name of local directory to save file
...	other options passed to readLines

Details

XML documents in the Open Access (OA) subset are downloaded from the OAI service. The namespace is removed for easier XPath queries and carets (^) are added to superscript tags and hyperlinked footnotes for displaying text. The document is parsed using xmlParse in the XML package to generate the XML tree within the R session, so objects are stored as an XMLInternalDocument class and can be queried using XPath expressions. Finally, a local copy is saved using saveXML for reloading

Value

An XML internal document
