BlockSuite API Documentation / @blocksuite/store / Y / XmlFragment

Class: XmlFragment

Represents a list of YXmlElement.and YXmlText types. A YxmlFragment is similar to a YXmlElement, but it does not have a nodeName and it does not have attributes. Though it can be bound to a DOM element - in this case the attributes and the nodeName are not shared.
