Using A Visitor about commonmark-java

[robinst]

Thanks @pcj, that's right. Maybe we should change the example to something more meaningful. Maybe visiting all links and printing the destination? Any other ideas?

Paragraph nodes are not terminal nodes, they typically contain children that ultimately lead to terminals, like code and text elements. Descend down the tree as you are doing with visitChildren and override visit(Text) and get the string literal from there:

        @Override
        public void visit(org.commonmark.node.Text node) {
            System.out.println(node.getLiteral());
        }

Okay thanks. I had seen Issue #8 and thought that maybe CommonMark might work the same as Pegdown where you can get the content of the node as a string. I was hoping to use Commonmark's AST to do syntax hi-lighting as Pegdown has so many dependencies and I prefer CommonMark's renderer.

@robinst Word counting examples are pretty standard in the text mining / classification domains. Could update the example to count words in a Markdown document.

Good idea, changed the example now: https://github.com/atlassian/commonmark-java#use-a-visitor-to-process-parsed-nodes
