QUESTION
ok, so I'm new to web scraping. I followed a tutorial I found on the internet and it works a treat for a specific website. so I tried to change it up to work for another site. I think I have figured out the headers as I get a 200 response, But when I'm targeting a div to pull its value I am just met with null. So my question is am I doing something wrong here? I have tried to follow other tuts to see if it would answer my question, But I guess because I am new I'm not really sure what to look for?!
EDIT: I should be a bit more specific. so as you can see in my code, I am trying to scrape data from Chaos cards website, I think I have the search function sorted (could be wrong?) but what I'm trying to achieve is when I inspect the page I would like to take the data from
Out of stock
Specifically the "Out of stock" part. as I know this div will contain "in stock" assuming it is. But when I target this div I am just met with null
All I am trying to do is set up a scrapper that when a user in discord types a specific product it will search the website, if it is in stock or not, it will return saying in stock or not in stock. But for now I'm trying to take baby steps, and just get it to firstly print the data I'm after

This is how Chrome render this page:
The font size is set to 100% in the whole table.
And here the render in Firefox Developer Edition
...ANSWER
Answered 2022-Jan-07 at 21:55Every browsers have different default values, even though most of them are same.
Designers usually tackle this problem by normalizing/reseting the default browser values using a Normalize Script.
You can read about this more in this article.
Also you can use a CSS reset like the one from YUI. It will make your pages more consistent across all browsers, including font rendering.

QUESTION
I'm trying to create a plot with ggplot()
and geom_text()
, to have a text annotation at the very right end of the plot, but still have the text aligned left. I've tried many combinations of x
positioning and hjust
, but so far to no avail.
Let's create a boxplot based on ToothGrowth
built-in dataset. At the initial stage, I want to have a geom_hline()
specific to each facet mean as follows:
ANSWER
Answered 2021-Sep-11 at 20:58I believe ggtext's geom_textbox()
can do what you're looking for. In introduces a seperation of hjust
and halign
to seperately align the box and the text.
QUESTION
I have a character string of 400 URLs called URLs. I have a loop that has been working for a while but now it takes way too long. It used to just report the url as an error and then I would omit but its is getting hung up.
...ANSWER
Answered 2021-Sep-08 at 18:55I think the issue I am running into is due to the open connections. The script would get progressively slower and I feel it was due to the old connections. Here is a simple loop that closes out all of the connections. I will know when I run a particular report again if this is the solution but it has seemed to help so far.
QUESTION
I am trying to move my web site to use ES2015 including the use of export and import to control access to shared resources. This means that javascript files which formerly were explicitly included using HTML tags are now accessed using import statements. So I am moving from pages which include the following:
...ANSWER
Answered 2021-Mar-15 at 07:58It's not clear which module your initializeMaps()
function is defined in, but that particular Google API requires that it be a global symbol so Google can find it when that script executes. And, it will have to be defined before the Google script executes too.
With ES6 modules, nothing in the script is automatically defined as globally available. So, unlike the older script files, top level variables in your script only have module scope and are not available globally. This is an important change with ES6 modules. You have to either export
a symbol to make it available to other scripts or you have to explicitly make it global by assigning it to the window
object (in the browser) like this:

QUESTION
I recently came to know of the ICC profile format. As part of a broader project I am working on, I need some source code of a few .icc files and their corresponding parse trees (or alternatively a .icc file parser).
I have searched the internet looking for the same and now I am thoroughly confused about the following concepts:
(1) Does a .icc file have source code? It's hard to enough to find a sample .icc file on the net, and the ones I found on github cannot open without the "Microsoft Color Control Panel" and that doesn't mention the source code.
(2) Once I have the source code, is their an existing parser to generate a parse tree for such a file?
By 'source code' I mean: Following link displays an html file: https://en.wikipedia.org/wiki/Pythagorean_theorem
And it's source code looks sth like:
...ANSWER
Answered 2021-Feb-04 at 22:00.icc files do not have a "source code" in the sense in which people normally use the term "source code". You might say, the .icc file is the source code, and it is interpreted by software that does something about images.
So if you have the .icc file, then you have the source code.
You probably have some .icc files on your computer, e.g. (from www.colourmanagement.net):
- ubuntu:
/usr/share/color/icc
- windows:
\system32\spool\drivers\color
- mac:
/Library/ColorSync/Profiles
or/Users//Library/ColorSync/Profiles
The ICC file format is ... well, a file format, like JPG or WAV. It's a sequence of bytes. I found the ICC Specification here on the page ICC Specifications.
To load and inspect a .icc file from an own program, I assume there are libraries for some programming languages. It seems that the ICC provides some themselves.
