x/net/html: ParseFragment fails to parse sub-table elements in the root position #7232
Description
by algorithmicimperative:
1. Use `html.ParseFragment` to parse a fragment of HTML where the root elements are
`<tbody>`, `<tr>` or `<td>` (and probably other table sub-elements)
For example:
s := `<td>first</td>
<td>second</td>
<td>third</td>
`
doc, err := html.ParseFragment(strings.NewReader(s), &html.Node{
Type: html.ElementNode,
Data: "body",
DataAtom: atom.Body,
})
2. Check the result `fmt.Printf("%#v\n", doc)`
What is the expected output?
`[]*html.Node` of 3 `td` elements
What do you see instead?
`[]*html.Node` of a single text node containing the `first second third` text.
Which operating system are you using? Linux
Which version are you using? 1.2
ParseFragment works fine with other semantically incorrect structures, like
`<option>` elements. Has trouble with table sub-elements though.
If this isn't a bug and is failing by design, perhaps we need something like
`atom.DocumentFragment` that will receive any arbitrary HTML.
