XPath recommendations?

[Pete]

To extract something from HTML I currently use regex via ASObjC. XPath is probably the correct way to do it, right? Do you have recommendations (links, tips, do & don’t do) how to start to get my head around XPath?

Searching the forum I found …

@ShaneStanley

Here’s that link to an introduction to XPath again:

https://www.w3schools.com/xml/xpath_intro.asp

… and …

@ComplexPoint

In addition to the following-sibling::* axis, and the // all descendants abbreviation we also have the ‘axes’ listed at:

Axes

For further information on using XPath expressions, please see the For Further Reading section at the end of Transforming XML with XSLT document. Also see the ‘axes’ section in the xpath spec.

… but didn’t check them yet.

As XPath seems complex, I figured it’s better to ask before I waste time with (potentially) bad introductions.

I use XPathQuery4ObjC for XPath processing.

GitHub - cybergarage/XPathQuery4ObjC: XPathQuery for Objective-C is a wrapper...

Sample script is here.

@Piyomaru you’re now on a very good way to become my favorite user I will check this out!

I re-checked XPath script in macOS Ventura and I found it does not work now.

Hmm…XPath is the essential technology. So, we have to find the replacement.
