## nu.xom.converters
Class DOMConverter

    Object
      nu.xom.converters.DOMConverter

public class DOMConverter
extends Object

Converts XOM `Document` objects to and from DOM `Document` objects. This class can also convert many DOM node objects into the corresponding XOM node objects. However, the reverse is not possible because DOM objects cannot live outside their containing `Document`.

Method Detail

### convert

    public static Document convert(org.w3c.dom.Document domDocument)

  Translates a DOM `org.w3c.dom.Document` object into an equivalent `nu.xom.Document` object. The original DOM document is not changed. Some DOM `Document` objects cannot be serialized as namespace well-formed XML, and thus cannot be converted to XOM.

  Parameters:
    `domDocument` - the DOM document to translate
  Returns:
    a XOM document
  Throws:
    `XMLException` - if the DOM document is not a well-formed XML document

### convert

    public static Nodes convert(org.w3c.dom.DocumentFragment fragment)

  Translates a DOM `org.w3c.dom.DocumentFragment` object into an equivalent `nu.xom.Nodes` object. The original DOM document fragment is not changed. Some DOM `DocumentFragment` objects cannot be serialized as namespace well-balanced XML, and thus cannot be converted to XOM.

  Parameters:
    `fragment` - the DOM document fragment to translate
  Returns:
    a `Nodes` containing the converted fragment members
  Throws:
    `XMLException` - if the DOM object is not a well-balanced XML fragment

### convert

    public static Comment convert(org.w3c.dom.Comment comment)

  Translates a DOM `org.w3c.dom.Comment` object into an equivalent `nu.xom.Comment` object. The original DOM object is not changed. Some DOM `Comment` objects cannot be serialized as well-formed XML, and thus cannot be converted to XOM.

  Parameters:
    `comment` - the DOM comment to translate
  Returns:
    a XOM comment
  Throws:
    `XMLException` - if the DOM comment is not a well-formed XML comment

### convert

    public static Text convert(org.w3c.dom.Text text)

  Translates a DOM `org.w3c.dom.Text` object into an equivalent `nu.xom.Text`. This method will also convert `org.w3c.dom.CDATA` objects. The original DOM object is not changed. Some DOM `Text` objects cannot be serialized as well-formed XML, and thus cannot be converted to XOM.

  Parameters:
    `text` - the DOM text to translate
  Returns:
    a XOM text
  Throws:
    `XMLException` - if the DOM text is not a well-formed XML text

### convert

    public static Attribute convert(org.w3c.dom.Attr attribute)

  Translates a DOM `org.w3c.dom.Attr` object into an equivalent `nu.xom.Attribute` object. The original DOM object is not changed. Some DOM `Attr` objects cannot be serialized as well-formed XML, and thus cannot be converted to XOM. Furthermore, DOM uses `Attr` objects to represent namespace declarations. XOM does not. Converting an `Attr` object that represents an `xmlns` or `xmlns:prefix` attribute will cause an exception.

  Parameters:
    `attribute` - the DOM `Attr` to translate
  Returns:
    the equivalent XOM `Attribute`
  Throws:
    `XMLException` - if the DOM `Attr` is a namespace declaration or is not a well-formed XML attribute

### convert

    public static ProcessingInstruction convert(org.w3c.dom.ProcessingInstruction pi)

  Translates a DOM `org.w3c.dom.ProcessingInstruction` object into an equivalent `nu.xom.ProcessingInstruction` object. The original DOM object is not changed. Some DOM `ProcessingInstruction` objects cannot be serialized as well-formed XML, and thus cannot be converted to XOM.

  Parameters:
    `pi` - the DOM `ProcessingInstruction` to convert
  Returns:
    a XOM `ProcessingInstruction`
  Throws:
    `XMLException` - if the DOM `ProcessingInstruction` is not a well-formed XML processing instruction

### convert

    public static DocType convert(org.w3c.dom.DocumentType doctype)

  Translates a DOM `org.w3c.dom.DocumentType` object into an equivalent `nu.xom.DocType` object. The original DOM object is not changed. The internal DTD subset is not converted, but the root element name, system identifier, and public identifier are. Some DOM `DocumentType` objects cannot be serialized as well-formed XML, and thus cannot be converted to XOM.

  Parameters:
    `doctype` - the DOM `DocumentType` to convert
  Returns:
    the equivalent XOM `DocType`
  Throws:
    `XMLException` - if the DOM `DocumentType` is not a well-formed XML document type declaration

### convert

    public static Element convert(org.w3c.dom.Element element)

  Translates a DOM `org.w3c.dom.Element` object into an equivalent `nu.xom.Element` object. The original DOM object is not changed. Some DOM `Element` objects cannot be serialized as namespace well-formed XML, and thus cannot be converted to XOM.

  Parameters:
    `element` - the DOM `Element` to convert
  Returns:
    the equivalent XOM `Element`
  Throws:
    `XMLException` - if the DOM `Element` is not a well-formed XML element

### convert

    public static org.w3c.dom.Document convert(Document document,
                                               org.w3c.dom.DOMImplementation impl)

  Translates a XOM `nu.xom.Document` object into an equivalent `org.w3c.dom.Document` object. The original XOM document is not changed. Since DOM2 internal subsets are read-only, the internal DTD subset is not converted. All other aspects of the document should be translated without a problem.

  Parameters:
    `document` - the XOM document to translate
    `impl` - the specific DOM implementation into which this document will be converted
  Returns:
    a DOM document
