Attribute selectors not fully parsed

[cvrebert]

Currently, the parse tree doesn't include full details for attribute selectors. For example, [att*=val] is parsed into:

{"type":"selectors","nodes":[
  {
    "type":"selector",
    "nodes":[
      {
        "type":"attribute",
        "content":"att*=val"
      }
    ]
  }
]}

It would be better if the "content" was further parsed, so we could get something like:

{"type":"selectors","nodes":[
  {
    "type":"selector",
    "nodes":[
      {
        "type":"attribute",
        "name":"att",
        "operator":"*=",
        "content":"val"
      }
    ]
  }
]}

The ASCII-case-insensitive attribute value flag (e.g. [type=radio i]) also needs to be accounted for.

Any progress with this?

Here is a RegExp that I've been working on to parse attribute selectors.

/^\s*((?:\\.|[A-Za-z_\-\u{00a0}-\u{10ffff}])(?:\\.|[A-Za-z_\-0-9\u{00a0}-\u{10ffff}])*)(?:\s*(=|~=|\|=|\^=|\$=|\*=)\s*"?(.+?)"?)?\s*(i)?\s*$/u

$1 - name
$2 - operator (i.e =)
$3 - value
$4 - ASCII-case-insensitive attribute value flag

BUGS

• can work with syntax errors
• when omitting quotes captures everything before whitespace and i as value
