使用 bash 解析 HTML 片段？

Question

I want to parse out the tag name (first item) from docker hub using strictly bash.

Example: https://hub.docker.com/_/node?tab=tags (input)

Output:

latest

This image latest tag is latest whereas mine as the most recent commits (dynamic). What is the best way to do this? I was able to use wget to store the contents into a string. I see xmllint, but not quite sure how to go about it.

Answer 1

It is not possible to use basic tools such as wget or curl.

If you disable javascript in your browser, you can see that the page have no rendering content at all.

So the only one solution is to use a tool like puppeteer or selenium that are javascript capable
