PHP DOMDocument schemaValidate但获取类型

Sa I have two types of schemas, one for <Request> and one for <Response>. I have the schema xsd for both.

I want to be able to get the "type" of the schema, even if it is invalid. For example, <Request to2="">... should be invalid, but I want to still know that this is a Request.

The problem is $xml->schemaValidate(...) will return false for both of my schemas if the attributes are also wrong.

(this example is simplified, in reality, I can have multiple verbs for each schema types, so I don't want to iterate through the child nodes and check what the nodeType is).

Is there a way to use DOMDocument to validate the choice only (no attribute validation)?

For instance:

<Request>...</Request>                      ---> {type: 'Request', isValid: true},
<Response>...</Response>                    ---> {type: 'Response', isValid: true},

<Request to="api/action">...</Request>      ---> {type: 'Request', isValid: true},
<Request tooo="api/action">...</Request>    ---> {type: 'Request', isValid: false},

<Response type="json">...</Response>        ---> {type: 'Response', isValid: true},
<Response typeeee="json">...</Response>     ---> {type: 'Response', isValid: false},

If I juse use $xml->schemaValidate('/path/to/request.xsd'); and $xml->schemaValidate('/path/to/response.xsd'); I will not be able to determine the type of <Request tooo="api/action">...</Request> and <Response typeeee="json">...</Response> respectively because they are "invalid"

Generate a combined XSD that validates both types according to their tag name.
