I stared at my code for a solid 5 mins trying to figure out what I screwed up (19:35) I created my own XML file, and by this point knew it was working just fine. Turns out...i did not capitalize the nodes in the XML file, but I did capitalize them in the code. It's amazing how "Name" is totally different from "name". No sarcasm, it's flexible.
Nicely explained the concept of how to approach an XML file. Thanks for all those details. I searched your videos and couldn't find anything else about how to use XML files for data analysis. I mean: get needed attributes, nodes and export them into data-frame or CSV file for a further convenient use. There are plenty of 'simple' samples of XML to CSV transformations online, but none with a real 'complex' structured XML with attributes in sub-child and such. Would it be possible for you to create such 'in demand' tutorial? BTW, bought your book '3 in 1' and hope to learn a lot on data science. Cheers,
How to extract values from a tag that has multiple child. For example, if the had multiple tags with then it only gives the first element not the second one.
How are you supposed to know that these 3 functions are getting called in the original class? In your code it is not obvious that they are getting called at all.
Hi. In the dom section of your tutorial when you used getElementByTagName you used the index [0] for each of the name, age, weight and height. May I ask you to explain that? I thought since we have a for loop which can take care of getting first index. Please explain
Thank you for this, it was actually easy to understand. But I replicated the last line where you wrote to the XML file, and it didn't work... help please.
@@NeuralNine Yes of course it's very good, but I have another question how do you read more than 1 xml file? I hear that have to use the glob function like a said I'm starting.
This is not a intermideate level. Its a beginner level. I mean come on the xml you chose is sooo simple. Choose the words of your title carefully. otherwise you might invite some dislikes like i am disliking your video right now.
I've done a few paid python courses, from beginner to intermediate, and none of them taught how to work with xml. The file he used might be simple, but the python code itself isn't

I cant see ur XML file in the description...
Very good explanation. Finally I understood how to deal with XML files.
You just saved me a day of work ! Keep up the good content ... +1 sub 👍
glad to hear that appreciate it :)
Very well explained, thank you, can you please also suggest how to get the outputs as a separate dataframe/file (especially from the first method).
BEST XML TUTORIAL FOR PYTHON THANK YOU !!!

Can yu tell how can i extract xml file in python to csv for data analysis
Thanks Mate

Can you make a vid of the top 5 best things you can make in Python?
I will make some project videos and project idea videos in the future but currently I am working on the data science playlist! :)
Awesome video I am impress just one question how to pass all this info to a data base or a mean a SQlite database?,,, very nice code again
Have you watched the tutorial about databases? :)

this example is a little too simple could you do one with a more complex site like yahoo finance? How would i go about parsing the table on it
very amazing! + 1 sub
What if i wanted to count how many times each age pops up.
From which college you learned all that.
I didn't learn Python in college at all. But I currently study at the Technical University of Vienna
