xbrlfiles's Issues

Schema file does not exist in XBRL file

I've posted a problem on stackoverflow. There are two fundamental issues:

1. Does XBRL.R support inline XBRL files
2. Can the package be updated to use a URL library, as per the current answer on the stackoverflow post.

Hoping you could take a look and offer any thoughts.

Thanks

error : Unknown IO error I/O warning : failed to load external entity

From both RStudio and console R version 3.3.0 (2016-05-03) I am getting an IO error from the high and low level XBRL library commands that ends up locking my R session.

Code used is the example code from the CRAN pdf, and tested with multiple different xbrl xml files on SEC site as well as stored locally.

The level 1 function, xbrlDoAll, fails straight away with an IO error and then R hangs.
The level 2 functions work until you get to xbrl$openInstance(inst), which throws the I/O error.
If you continue to then ecexute xbrl$processSchema(xbrl$getSchemaName()) you will hang R - possibly what is happening when calling the level 1 function.

The level 3 function xbrlParse(inst) throws the same IO error. For convenience here is the example code:

## Setting stringsAsFactors = FALSE is highly recommended
## to avoid data frames to create factors from character vectors.
options(stringsAsFactors = FALSE)
## Load the library
library(XBRL)
## XBRL instance file to be analyzed, accessed
## directly from SEC website:
inst <- "http://www.sec.gov/Archives/edgar/data/21344/000002134413000050/ko-20130927.xml"

## Level 1: Function that does all work and returns
## a list of data frames with extracted information:
## Not run:
xbrl.vars <- xbrlDoAll(inst, verbose=TRUE)

## Level 2: Using the XBRL() "mutable state" function:
xbrl <- XBRL()
xbrl$setCacheDir("XBRLcache")
xbrl$openInstance(inst)
## Perform a discovery of the taxonomy:
xbrl$processSchema(xbrl$getSchemaName())
## Process instance file:
xbrl$processContexts()
xbrl$processUnits()
xbrl$processFacts()
xbrl$processFootnotes()
xbrl$closeInstance()
xbrl.vars <- xbrl$getResults()

inst <- "~/R/StockTickers/XBRLdocs/ph-20160331.xml"
xbrl$setCacheDir("~/R/StockTickers/XBRLdocs")
## End(Not run)

## Level 3: Using specialized functions that call C++ code directly:
## Parse the instance (doc is an pointer to external memory that needs to be freed):
doc <- xbrlParse(inst)
## Get a data frame with facts:
fct <- xbrlProcessFacts(doc)
## Get a data frame with contexts:
cts <- xbrlProcessContexts(doc)
## Get a data frame with units:
unt <- xbrlProcessUnits(doc)
## Free the external memory used:
xbrlFree(doc)
