将字符串拆分为HTML实体

Question

I'm trying to use PHP to create a JSON representation of a paragraph of text, keeping information about links/formatting etc.

Essentially, I want to convert this string:

"Hello <a href='www.google.com'>World!</a>.  How are <b>you</b> today?"

Into these 7 JSON objects:

"1": {
    "_id": "1",
    "_type": "TEXT",
    "value": "Hello "
},
"2": {
    "_id": "2",
    "_type": "TEXT",
    "value": "World!",
    "_attributes": {
        "3": {
            "_id": "3",
            "_type": "LINK",
            "src": "www.google.com"
        }
    }
},
"4": {
    "_id": "4",
    "_type": "TEXT",
    "value": " How are "
},
"5": {
    "_id": "5",
    "_type": "TEXT",
    "value": "you",
    "_attributes": {
        "6": {
            "_id": "6",
            "_type": "FORMATTING",
            "bold": true,
        }
    }
},
"7": {
    "_id": "7",
    "_type": "TEXT",
    "value": " today?"
}

I've hunted the internet/google and found plenty about splitting HTML, but can't seem to describe what I want. I need to separate the plain text from the link/formatting and create a single entity for each.

The "FORMATTING" attribute just adds "bold"/"underline"/"subscript" etc fields as appropriate.

Nested tags will simply create multiple attributes for their text entity.

I don't yet know how I'd handle a 2-word hyperlink that has one word bolded... perhaps it'll have to have 2 hyperlink attributes.

Any help MUCH appreciated!!

A DOMDocument is what you need. If you can live with slightly different names, you barely have to do any work, too.
