 """Initialize an XmlObject from a string. If an xmlclass is specified, construct an instance of that class instead of :class:`~eulxml.xmlmap.XmlObject`. It should be a subclass of XmlObject. The constructor will be passed a single node. If validation is requested and the specified subclass of :class:`XmlObject` has an XSD_SCHEMA defined, the parser will be configured to validate against the specified schema. Otherwise, the parser will be configured to use DTD validation, and expect a Doctype declaration in the xml content. :param string: xml content to be loaded, as a string :param xmlclass: subclass of :class:`~eulxml.xmlmap.XmlObject` to initialize :param validate: boolean, enable validation; defaults to false :rtype: instance of :class:`~eulxml.xmlmap.XmlObject` requested """
