That's my JSON:

I have more than 1000 XML files that probably have the same structure. I want to create a database using data in all the files. I have never known how an XML file looked before yesterday. With the help of Google, I tried using the r-packages to load a single XML file in RStudio. But when I'm trying to convert that into a data frame, an error is occurring.

This is how file looks like: File A

I have the following document for which I need to do mapping for elasticsearch

I want to scrape a website which has a list of products and each product has a specific page with more data. I wanted to do it using MAP ASYNC + PROMISE.ALL instead of FOR-OF, however I couldn't make it Work properly.

Working sample with for-of:

I have a data set that I want to run a number of univariate regressions with 20 variables or so. Listed below is a truncated data frame showing just two of the variables of interest (Age and Anesthesia). The regression works fine but the issue I am running into is how to store the data. Since Age has only coefficient but Anesthesia has >4 and the error I get is:

I have a json coming back from an API that I am appending to a list. After I finish making that call I need to flatten that data using pandas. I'm not sure how to do.

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

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")

I am making a GUI using PyQt5 that displays data in table. I want to get the item at a specific cursor position when 'Right-Click" is pressed. This is achieved using the contextMenuEvent function and works for all rows except the last. When clicking the last row of the table, it prints "None" instead of the QTableWidgetItem Object.

I'm confused as to why its returning None when it should return the last QTableWidgetItem.

I've tried tinkering with the event.pos() and changing it to globalPos(), thinking maybe the coordinates are wrong, but nothing has worked.

I'm having trouble debugging why I can't drop columns in my python file, whereas in my notebook I can drop the columns from my dataframe just fine.

Here is my code for my notebook:
