Or, at least make this information available to the tree builder?  I implemented a very minimal proof of concept to add the information to each token and pass that along to the dom tree builder and obtain the following result:\r\n\r\n```\r\nimport html5lib\r\n\r\nhtml = '\u003cdiv\u003e\u0026amp;\u003cp\u003eb\u003cspan\u003ec\u003c/span\u003e\u003c/p\u003e cab\u003c/div\u003e'\r\n\r\nparser = html5lib.HTMLParser(tree=html5lib.getTreeBuilder(\"dom\"))\r\n\r\ndoc = parser.parse(html)\r\ndef parse(n):\r\n    for c in n.childNodes:\r\n        if hasattr(c, 'sourcepos'):\r\n            print(c.sourcepos, c)\r\n        parse(c)\r\n\r\nparse(doc)\r\n```\r\n\r\n```\r\nNone \u003cDOM Element: head at 0x10bbed0d0\u003e\r\nNone \u003cDOM Element: body at 0x10bbed1f0\u003e\r\n(1, 5) \u003cDOM Element: div at 0x10bbfb790\u003e\r\n(1, 10) \u003cDOM Text node \"'\u0026'\"\u003e\r\n(1, 13) \u003cDOM Element: p at 0x10bbfb820\u003e\r\n(1, 14) \u003cDOM Text node \"'b'\"\u003e\r\n(1, 20) \u003cDOM Element: span at 0x10bbfb8b0\u003e\r\n(1, 21) \u003cDOM Text node \"'c'\"\u003e\r\n(1, 33) \u003cDOM Text node \"' '\"\u003e\r\n(1, 36) \u003cDOM Text node \"'cab'\"\u003e\r\n```\r\n\r\nI would be willing to implement it.","author":{"url":"https://github.com/corynezin","@type":"Person","name":"corynezin"},"datePublished":"2021-04-16T15:33:37.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/533/html5lib-python/issues/533"}
