- Demonstrate how XPath works against a live XML document.
This video is part of a playlist that describes how to use XML, XSD, and XSLT. See the entire playlist here: • XML and XSD: How do th...
These tips are great! The free online helpful websites are exactly what i needed to validate my code-Thank you:)
Excellent! Glad it helped. I occasionally go back to this video so I'll remember to use the sites. :)
This is the video I needed! Could not get my head around xpath until now. Thanks you 😊
Awesome! XPATH is a very powerful way to get what you want out of an XML document. I'm glad this video helped you!
Thanks Brandan! I'm really learning a lot from this series!
Best regards, from Belgium!!
Excellent, glad to hear it helps! I visited Brussels two years ago!
You probably dont give a damn but does someone know a way to log back into an Instagram account..?
I somehow forgot the account password. I would love any tips you can offer me
@Ronan Sullivan instablaster :)
@Finnley Kaiden I really appreciate your reply. I got to the site through google and Im trying it out now.
I see it takes quite some time so I will reply here later when my account password hopefully is recovered.
@Finnley Kaiden It did the trick and I now got access to my account again. Im so happy!
Thank you so much, you saved my account!
Excellent and well explained sir... Thank you for the video. It was exactly what I was looking for...😊
Glad it helped! Thanks.
Good stuff, thanks a lot.
Woah.. thanks a lot..you saved my college exams. and please Keep Uploading : )))
I have disliked XML for my entire career of 13 years. Partly because I never understood how it was really meant to be used. I just saw it as bloated data container format. Also I never understood the top few lines of XML. I had never worked on a XML heavy project, so never needed to dive deep...until now. Your tutorial series was an eye opener. I now understand what wonderful things XMLs and XSDs are. Thank you!
Thanks! I appreciate the feedback.
I had a similar journey... coming from the flat file or comma separated value world, I didn't fully grasp XML, until I saw it used for data import and interchange. Then, when I saw the role that XSD can play in validating XML data (essentially, a pre-validation step), it became very clear how XML can be used to ensure you have good data coming in.
When you look at it through the glasses of HTML, it's even more interesting. There's a DTD for several HTML styles. These describe the rules of HTML which many people know from memory, but may not be aware there's an official validation file for it.
While the world has largely moved to JSON lately, and JSON does have a schema, I don't think it's fully as mature as XSD. You have to choose OpenAPI or JSON Schema format, and I rarely see anyone use it as input validation. It's more a matter of, "here's what your JSON should look like" than "this field should be a number greater than 2, less than 6" as you can do in XSD. Granted, you can do that with JSON schema; it's just not often that I see anyone use it that way. I suspect we'll get there over time.
Thanks for watching!

Brandan! This is excelent! Thanks
Glad it helped! Thanks for the comments!
Thank you. It's Exactly what I need.
I'm glad it helped! Thanks.
Hi, thanks for the video, i am getting XPath set is empty when i try>>:: xmllint --xpath "//string to fetch" filepathxml what could be the problem?
practical and helpful
Glad it helped! Thanks for the comment.
Great stuff
Thanks! XPath is great for getting information quickly and accurately out of an XML document.
@@discospiff Hi Bradan, Can we update a specific attribute value using xmllint ? if yes, I would like to know the way forward. Thanks in Advance !
Can i use this for text or its only for numbers?
What do you want to do with the text?

I got this

I only want to extrude the titles Who have the author James.
a backslash \ points backwards (left), forward slash / points forward (right)
Thanks for the explanation. I've found that, even if I understand it, my audience might not. If I say, "backslash", 1/3 wil get it right, 1/3 wil get it wrong, and 1/3 will ask which one it is. :)
I say division/not division sign, to clarify😀
