XML literal issue

[terurou]

Describe the bug

haxe-formatter breaks the XML literal.

Input file

class Test {
    function main() {
        final user = "usr";

        XmlTools.toString(
            <soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:foo="https://foo.bar/baz">
                <soap:Header>
                    <foo:Foo>
                        <foo:User>${user}</foo:User>
                    </foo:Foo>
                </soap:Header>
                <soap:Body>
                </soap:Body>
            </soap:Envelope>
        );
    }
}

Broken output

class Test {
    function main() {
        final user = "usr";

        XmlTools.toString( < soap:Envelope xmlns:soap = "http://www.w3.org/2003/05/soap-envelope"
            xmlns:foo = "https://foo.bar/baz" ><soap:Header><foo:Foo><foo:User>${user} < / foo
            :User > < / foo:Foo > < / soap:Header ><soap:Body> < / soap:Body > < / soap:Envelope >);
    }
}

Expected output
Please keep valid xml.

Optional: hxformat.json

{
    "indentation": {
        "character": "    "
    },
    "sameLine": {
        "ifBody": "keep",
        "elseIf": "keep",
        "elseBody": "keep",
        "forBody": "keep",
        "whileBody": "keep"
    }
}

Someone would have to port the current state of Haxe's "Not-XML" to haxeparser lib, so formatter can understand it and see your xml as a single token. Currently your xml is treated like code. That's why it's formatted all broken up.

Since the direction of "Not-XML" is still unclear and under consideration, I skipped trying to port it last time I touched haxeparser. I am sure if someone makes a pull request to haxeparser implementing "Not-XML", its owner will gladly accept it.

Well, it might be a bit early even for a haxeparser PR given that it's not totally clear where the feature is going.

This one is critical and I have to turn off formatter without any choice...
