R: nested list from JSON/XML (clinicaltrials.gov) to data.frame (tidy)

How to change STDIN stream to binary

QUESTION

R: nested list from JSON/XML (clinicaltrials.gov) to data.frame (tidy)

Asked 2021-Feb-28 at 16:05

The purpose

For university research I try to process data of clinical studies publicly available here.

For reproducibility, I would like to directly use the downloaded JSON or XML files (and not to retrieve the data via the web API, which has been described: how-to-get-data-out-of-nested-xml-structure).

Update 1: The structure of the JSON file is published here

Update 2: The structure of the XML file is published here

Update 3:

I think tidyjson::read_json and tidyjson::spread_all do the trick! See the answer section.

What I need

For my workflow, I need to convert the data to data.frames (tidy data.frames would be even better). I prefer JSON, hoever, if there was a solution for the XML format I would be very glad.

Test data

A nested list that I generated of one of the downloaded JSON files with jsonlite::fromJSON("NCT0455805.json")

The package tidyjson works perfectly:

It is imortant to read the JSON file directly with tidyjson::read_json to get the right format (tbl_json (S3: tbl_json/tbl_df/tbl/data.frame) for further processing.

QUESTION

How to change STDIN stream to binary

Asked 2017-Apr-18 at 21:04

I'm making an upload form via a CGI interface. I'm writing it in C and don't want to use any outside libraries (ie. cgic).

I thought the program was complete, as the first test files uploaded correctly. But they were ASCII files. When I tested with a binary file (JPG). It seems that STDIN is trying to read the binary data as ASCII which creates a problem for characters like \0 which is present at the end of an ASCII file, but is a common character in binary files. The results of uploading a 1.9MB file end up with a 38kB file.

When searching how to change the STDIN stream to binary, I was referred to the command freopen and told to use NULL as the argument for the file. example 1

It says:

If filename is a null pointer, the freopen() function shall attempt to change the mode of the stream to that specified by mode, as if the name of the file currently associated with the stream had been used. In this case, the file descriptor associated with the stream need not be closed if the call to freopen() succeeds. It is implementation-defined which changes of mode are permitted (if any), and under what circumstances.

But when I check the man page on my system with man 3 freopen, it doesn't say any of this at all. Furthermore, reading the man page, I find out the the option for binary (adding 'b' to the mode) is no longer recognized and only exists for archaic compliancy:

The mode string can also include the letter 'b' either as a last character or as a character between the characters in any of the two-character strings described above. This is strictly for compatibility with C89 and has no effect; the 'b' is ignored on all POSIX conforming systems, including Linux.

So right now I'm completely lost. How can I change the STDIN stream to read binary input?

Here is the code:

'stdin' is a macro of STDIN_FILENO, which is egal to 0. See also 'unistd.h'. You are not showing your code, but I think you stop when you encounter a '\0' or a non-ascii char, since you said you were using 'fread()'.

You have to stop when fread() function returns 0, which means it stopped to read : it encountered EOF.
