HTML parser and lang node to send to lang parser. (only has html ast)

any lang node would be send and the lang ast would be seperate for that node

{
  type: 'element',
  tagName: 'div',
  properties: {className: ['foo'], id: 'some-id'},
  children: [
    {
      type: 'element', // element, text, comment, lang
      tagName: 'span',
      properties: {},
      children: [
      {
        type: "InstanceVariableReadNode",
        location: [[1,0],[1,6]]
        type: 'text',
        value: '<%= @posts %>'
      },
      {
        type: "InstanceVariableReadNode",
        location: [[1,0],[1,6]]
        type: 'text',
        value: '<%= @posts %>'
      }
	  ]
    },
  ]
}
<span <% if true %> class="mt-2 <%= post.title %>" <% end %> >
  <%= post.description %>
</span>

<% @posts.each do |post| %>
  <h1>
    <%= post.title %> -- <%= post.description %>
  </h1>
<% end %>

1. ide send file data to lsp server

2. lsp server parse html file data and send language nodes to be parsed/evaluated

3. ide use html tree to provide html autocomplete and language nodes to provide language autocomplete

{{}}


<div data-controller="autocomplete-works">
	<%= @posts %>
	<%= tag.div "Click", data: { controller: "autocomplete-doesn't-work"} %>
	<%= content_tag(:span, "Click", data: { controller: "autocomplete-doesn't-work"} %>
</div>
