Find raw HTML blocks

Goal: Locate embedded raw HTML in a Markdown document — useful before converting to a stricter Markdown flavor (e.g. plain CommonMark) or a renderer that doesn’t allow raw HTML passthrough.

Prerequisites: None.

Query

.html

$ mq '.html' README.md

Input

# Doc

Some text.

<div class="callout">
  <strong>Note:</strong> important info.
</div>

More text.

Output

<div class="callout">
  <strong>Note:</strong> important info.
</div>

Notes

• Run across a whole docs tree (mq '.html' docs/**/*.md) as a quick audit of how much raw HTML you’d need to rewrite before switching renderers.
• Gotcha: inline HTML tags inside a paragraph (e.g. text <span>inline</span> text) are matched too, but the opening and closing tags come back as two separate .html nodes (<span class="x"> and </span>) — and the text between them is dropped entirely, since that’s a plain text node this selector doesn’t touch. .html is reliable for auditing standalone HTML blocks; for inline HTML mixed into prose, treat the count as a rough signal rather than a clean extraction.
