XHTML and HTML

XHTML

HTML does not conform to XML syntax. It has unterminated tags such as <br>. XHTML is a cleanup of HTML to make it compliant to XML. Documents in XHTML can be managed using the techniques above for XML.

HTML

There is some support in the XML package to handle HTML documents even though they are not XML-compliant. The XML parser discussed earlier can handle many HTML documents if it is modified by

parser := xml.NewDecoder(r)
parser.Strict = false
parser.AutoClose = xml.HTMLAutoClose
parser.Entity = xml.HTMLEntity

Conclusion

Go has basic support for dealing with XML strings. It does not as yet have mechanisms for dealing with XML specification languages such as XML Schema or Relax NG.
