Is there a way to convert HTML to XHTML within VBA Excel?

After some days of research, I've found that other tools outside Excel/VBA use XHTML to be able to use Xpath.

Selenium is not an option since for security reasons is not allowed to install programs (.exe), then I was wondering if somebody knows if there is a microsoft library or how to convert from the HTML response in code below in line htmlDoc.body.innerHTML = .responseText to XHTML to be able to use Xpath expressions with SelectNodes() like in line Set elements = xhtmlDoc.SelectNodes("//body/div/div/div]")

Sub Html2Xhtml()
    Dim htmlDoc As New HTMLDocument
    Dim elements As MSXML2.IXMLDOMNodeList
    Dim url as String

    url = "https://www.example.com"

    With New ServerXMLHTTP60
        .Open "Get", url, False
        .send
        htmlDoc.body.innerHTML = .responseText
    End With
    
    xhtmlDoc = SomeFunction(htmlDoc.body.innerHTML)
    
    Set elements = xhtmlDoc.SelectNodes("//body/div/div/div]")
    
End Sub
