I'm trying to get something from a webpage using something like this

I am trying to extract pubmed abstracts and their titles to place them in a dataframe. will the help of members stackoverflow, I was able to write the code below, which works. The issue now is that the number of rows in the abstracts variable is higher than that of pmid or title, therefore I am unable to merge them correctly. Looking at the structure of the xml file I have, it appears the abstracts have more than one ?node, that's why they get extracted in > one row. Any suggestion how to overcome that and have each abstract in one row, so I can merge the variables.

Here is my code:

This is continuation for the same task I am trying to perform from this question. Working with pubmed api in R (httr) to retrieve abstracts

using the answer below, I am able to find the pubmed IDs for the abstracts of interest.

Now, I am trying to obtain the title and full text of these abstracts (as 2 columns dataframe, one for title and one for abstract text).

what I understood from the api documentation is that passing multiple IDs is possible, so I tried the code below.

I am trying to work directly with the pubmed api from R using httr. There are excellent packages available such as RISmed and easypubmed but for this particular task, I need to interact directly with the api.

Using this set of instructions (https://www.ncbi.nlm.nih.gov/books/NBK25500/), I started with this code but the returned is a list without any details or pmid. Any guidance is appreciated. or if you are aware of particular tutorials on using R in this setting.

I'm trying to pull xml data from some link with simplexml_load_file.
This one xml node I am trying to access is an array with 4 elements.
Each element has a label which I am trying to read.
I try to read each label using the attributes() function, but for some reason the function only returns the first node label.

When I try to convert an XML file (requested from an external server) to JSON, it seems to me that xml2json does convert it however, not to a correct JSON file. Is there something that needs to be adjusted. I seem to be missing quotes for the keys.

This is my current code

I'm trying to get some data using the NCBI API. I am using requests to make the connection to the API.

What I'm stuck on is how do I convert the XML object that requests returns into something that I can parse?

Here's my code for the function so far:

I have been successful at extracting affiliation data from a single pubmed record, by using easyPubMed & lots of searching (I am still very new to R). The issue with the data is that it is only reporting one part of the affiliation information, I am assuming this is due to the various types of information in a non-standardised string.

My code is as follows:

I have a xml data
