9. XPath examples and demonstrations in XML

[@lhxperimental]

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

Excellent! Glad it helped. I occasionally go back to this video so I'll remember to use the sites. :)

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?

@Ronan Sullivan instablaster :)

[@ronansullivan5036]

@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.

[@ronansullivan5036]

@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!

This is the video I needed! Could not get my head around xpath until now. Thanks you 😊

[@discospiff]

Awesome! XPATH is a very powerful way to get what you want out of an XML document. I'm glad this video helped you!

[@wasabulldog7755]

Can i use this for text or its only for numbers?

[@discospiff]

What do you want to do with the text?

Woah.. thanks a lot..you saved my college exams. and please Keep Uploading : )))

a backslash \ points backwards (left), forward slash / points forward (right)

[@discospiff]

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. :)

[@pawemotylski9278]

I say division/not division sign, to clarify😀

Thanks! XPath is great for getting information quickly and accurately out of an XML document.
