Extracting a text from a webpage

I need the HTML code as text (not an image) that covers all of the above, plus one node level above that.

To enter the HTML as text in a Markdown Code Block, see:

How to Put Script in a Forum Code Block

Just insert your script/code/text between the lines with the triple backquotes:

See Markdown for Code Blocks

To get syntax highlighting, then use the keyword in lower case for that language, like:
applescript
javascript
html

Here is a macro that will paste the script on the clipboard into the forum in the proper format:
