Extract specific Heading from document if exists

[mmiranda]

Is there any way to check if my document has a specific Heading title? And in case there is how can I extract its section from the document?

I appreciate the help.

What I got so far was this:

        doc := gm.Parser().Parse(text.NewReader(source))
	ast.Walk(doc, func(n ast.Node, entering bool) (ast.WalkStatus, error) {
		s := ast.WalkStatus(ast.WalkContinue)
		var err error
		if n.Kind().String() == "Heading" && string(n.Text(source)) == "Title I'm filtering" {
		        // Apply any logic here

                         // gets the title
			fmt.Println(string(n.Text(source)))
                         // get block content
			fmt.Println(string(n.NextSibling().Text(source)))

                         // Stop walking
			s = ast.WalkStatus(ast.WalkStop)
		}
		return s, err
	})

Is this the right way to do it?

Thanks for sharing this! I really wanted a minimal example like this and it is just the ticket.

@mmiranda hey thanks for the example super helpful. I had another question i was hoping you could help wtih; can you please elaborate the difference between TextBlock, and Paragraph? Similarly Text vs String? I went through the docs but didnt find anything helpful there.

Thanks in advance 🙏🏾
