Direct Known Subclasses:

XDOMUtil

public class DOMUtil
extends Object

Some useful utility methods. This class was modified in Xerces2 with a view to abstracting as much as possible away from the representation of the underlying parsed structure (i.e., the DOM). This was done so that, if Xerces ever adopts an in-memory representation more efficient than the DOM (such as a DTM), we should easily be able to convert our schema parsing to utilize it.

                                    String localName)

getNamespaceURI

public static String getNamespaceURI(Node node)

getInputEncoding

public static String getInputEncoding(Document doc)

Get the input encoding of the document. This uses a DOM 3 API call getInputEncoding hence it returns the correct value only if a DOM3 API is used. Otherwise it returns the default encoding

Parameters:

doc -

Returns:

the encoding (e.g. UTF-8)

getXmlEncoding

public static String getXmlEncoding(Document doc)

Get the xml encoding of the document. This uses a DOM 3 API call getXmlEncoding hence it returns the correct value only if a DOM3 API is used. Otherwise it returns the default encoding

Parameters:

doc -

Returns:

the encoding (e.g. utf-8).
