    Returns a string representation as XML document from this element and all it's children (recursively).
    The charset used in the xml header is the current page encoding; but the result is still a string. You have to make sure to use the correct (in fact the same) encoding if you write this to a file.
    This serializes the current state of the DomTree - this implies that the content of noscript tags usually serialized as string because the content is converted during parsing (if js was enabled at that time).
    
    Returns:
    
    the XML string

```
    INTERNAL API - SUBJECT TO CHANGE AT ANY TIME - USE AT YOUR OWN RISK.
    
    Returns the JavaScript object that corresponds to this node, lazily initializing a new one if necessary.
    
    The logic of when and where the JavaScript object is created needs a clean up: functions using a DOM node's JavaScript object should not have to check if they should create it first.
    
    Type Parameters:
    
    T - the object type
    
    Returns:
    
    the JavaScript object that corresponds to this node

```
    Specified by:
    
    replaceChild in interface Node
  - replace
```
public void replace(DomNode newNode)
```
    Replaces this node with another node. If the specified node is this node, this method is a no-op.
    
    Parameters:
    
    newNode - the node to replace this one
  - quietlyRemoveAndMoveChildrenTo
```
public void quietlyRemoveAndMoveChildrenTo(DomNode destination)
```
    INTERNAL API - SUBJECT TO CHANGE AT ANY TIME - USE AT YOUR OWN RISK.
    Quietly removes this node and moves its children to the specified destination. "Quietly" means that no node events are fired. This method is not appropriate for most use cases. It should only be used in specific cases for HTML parsing hackery.
    
    Parameters:
    
    destination - the node to which this node's children should be moved before this node is removed
  - checkChildHierarchy
```
protected void checkChildHierarchy(Node newChild)
                            throws DOMException
```
    Check for insertion errors for a new child node. This is overridden by derived classes to enforce which types of children are allowed.
    
    Parameters:
    
    newChild - the new child node that is being inserted below this node
    
    Throws:
    
    DOMException - HIERARCHY_REQUEST_ERR: Raised if this node is of a type that does not allow children of the type of the newChild node, or if the node to insert is one of this node's ancestors or this node itself, or if this node is of type Document and the DOM application attempts to insert a second DocumentType or Element node. WRONG_DOCUMENT_ERR: Raised if newChild was created from a different document than the one that created this node.
  - onAddedToPage
```
protected void onAddedToPage()
```
    Lifecycle method invoked whenever a node is added to a page. Intended to be overridden by nodes which need to perform custom logic when they are added to a page. This method is recursive, so if you override it, please be sure to call super.onAddedToPage().
  - onAllChildrenAddedToPage
```
public void onAllChildrenAddedToPage(boolean postponed)
```
    Lifecycle method invoked after a node and all its children have been added to a page, during parsing of the HTML. Intended to be overridden by nodes which need to perform custom logic after they and all their child nodes have been processed by the HTML parser. This method is not recursive, and the default implementation is empty, so there is no need to call super.onAllChildrenAddedToPage() if you implement this method.
    
    Parameters:
    
    postponed - whether to use PostponedAction or no
  - onAddedToDocumentFragment
```
protected void onAddedToDocumentFragment()
```
    Lifecycle method invoked whenever a node is added to a document fragment. Intended to be overridden by nodes which need to perform custom logic when they are added to a fragment. This method is recursive, so if you override it, please be sure to call super.onAddedToDocumentFragment().

  - getDescendants
```
public final Iterable<DomNode> getDescendants()

    an Iterable that will recursively iterate over all of this node's descendants
  - getHtmlElementDescendants
```
public final Iterable<HtmlElement> getHtmlElementDescendants()
```
    Returns an Iterable that will recursively iterate over all of this node's HtmlElement descendants. If you want to iterate over all descendants (including DomText elements, DomComment elements, etc.), please use getDescendants().
    
    Returns:
    
    an Iterable that will recursively iterate over all of this node's HtmlElement descendants
    
    See Also:
    
    getDomElementDescendants()
  - getDomElementDescendants

  - getByXPath
```
public <T> List<T> getByXPath(String xpathExpr)
```
    Evaluates the specified XPath expression from this node, returning the matching elements.
    Note: This implies that the ',' point to this node but the general axis like '//' are still looking at the whole document. E.g. if you like to get all child h1 nodes from the current one you have to use './/h1' instead of '//h1' because the latter matches all h1 nodes of the# whole document.
