Parameters:

node - DOM Node

locator - Callback to find location of node. May be null.

Method Detail

getType

public int getType()

Map the Node's type to DOMWrapper's simplified concept of type.

public String[] getAttributeNames()

Description copied from interface: DOMWrapper

Returns a list of attribute names.

Specified by:

toXML

public String toXML()

Description copied from interface: DOMWrapper

Returns this node serialized as XML.

Specified by:

toXML in interface DOMWrapper

getChildren

public DOMWrapper[] getChildren()

Retrieve all children, and build an array of W3CDOMWrappers around each child that is of TEXT or ELEMENT type to return.

Specified by:

getChildren in interface DOMWrapper

getElementChildren

Retrieve all children, and build an array of W3CDOMWrappers around each ELEMENT child.

Specified by:

getElementChildren in interface DOMWrapper

getLocation

public Location getLocation()

Description copied from interface: DOMWrapper
