Java compact2, compact3 javax.xml.parsers Class DocumentBuilder（JDK8）

Constructor Detail

• DocumentBuilder

  protected DocumentBuilder()

  Protected constructor

Method Detail

• reset

  public void reset()

  Reset this DocumentBuilder to its original configuration.

  DocumentBuilder is reset to the same state as when it was created with DocumentBuilderFactory.newDocumentBuilder(). reset() is designed to allow the reuse of existing DocumentBuilders thus saving resources associated with the creation of new DocumentBuilders.

  The reset DocumentBuilder is not guaranteed to have the same EntityResolver or ErrorHandler Objects, e.g. Object.equals(Object obj). It is guaranteed to have a functionally equal EntityResolver and ErrorHandler.

  Throws:

  UnsupportedOperationException - When implementation does not override this method.

• parse

  public Document parse(InputStream is)
                 throws SAXException,
                        IOException

  Parse the content of the given InputStream as an XML document and return a new DOM Document object. An IllegalArgumentException is thrown if the InputStream is null.

  Parameters:

  is - InputStream containing the content to be parsed.

  Returns:

  Document result of parsing the InputStream

  Throws:

  IOException - If any IO errors occur.

  SAXException - If any parse errors occur.

  IllegalArgumentException - When is is null

                 throws SAXException,
                        IOException

  Parse the content of the given InputStream as an XML document and return a new DOM Document object. An IllegalArgumentException is thrown if the InputStream is null.

  Parameters:

  is - InputStream containing the content to be parsed.

  systemId - Provide a base for resolving relative URIs.

  Returns:

  A new DOM Document object.

  Throws:

  IOException - If any IO errors occur.

  SAXException - If any parse errors occur.

• parse

  public Document parse(String uri)
                 throws SAXException,
                        IOException

  Parse the content of the given URI as an XML document and return a new DOM Document object. An IllegalArgumentException is thrown if the URI is null null.

  Parameters:

  uri - The location of the content to be parsed.

  Returns:

  A new DOM Document object.

  Throws:

  IOException - If any IO errors occur.

  SAXException - If any parse errors occur.

  IllegalArgumentException - When uri is null

• parse

  public Document parse(File f)
                 throws SAXException,
                        IOException

  Parse the content of the given file as an XML document and return a new DOM Document object. An IllegalArgumentException is thrown if the File is null null.

  Parameters:

  f - The file containing the XML to parse.

  Returns:

  A new DOM Document object.

  Throws:

  IOException - If any IO errors occur.

  SAXException - If any parse errors occur.

  IllegalArgumentException - When f is null

  public abstract Document parse(InputSource is)
                          throws SAXException,
                                 IOException

  Parse the content of the given input source as an XML document and return a new DOM Document object. An IllegalArgumentException is thrown if the InputSource is null null.

  Parameters:

  is - InputSource containing the content to be parsed.

  Returns:

  A new DOM Document object.

  Throws:

  IOException - If any IO errors occur.

  SAXException - If any parse errors occur.

• isNamespaceAware

  public abstract boolean isNamespaceAware()

  Indicates whether or not this parser is configured to understand namespaces.

  Returns:

  true if this parser is configured to understand namespaces; false otherwise.

• isValidating

  public abstract boolean isValidating()

  Indicates whether or not this parser is configured to validate XML documents.

  Returns:

  true if this parser is configured to validate XML documents; false otherwise.

• setEntityResolver

  public abstract void setEntityResolver(EntityResolver er)

  Specify the EntityResolver to be used to resolve entities present in the XML document to be parsed. Setting this to null will result in the underlying implementation using it's own default implementation and behavior.

  Parameters:

  er - The EntityResolver to be used to resolve entities present in the XML document to be parsed.

• setErrorHandler

  public abstract void setErrorHandler(ErrorHandler eh)

  Specify the ErrorHandler to be used by the parser. Setting this to null will result in the underlying implementation using it's own default implementation and behavior.

  Parameters:

  eh - The ErrorHandler to be used by the parser.

• newDocument

  public abstract Document newDocument()

  Obtain a new instance of a DOM Document object to build a DOM tree with.

  Returns:

  A new instance of a DOM Document object.

• getDOMImplementation

  public abstract DOMImplementation getDOMImplementation()

  Obtain an instance of a DOMImplementation object.

  Returns:

  A new instance of a DOMImplementation.

• getSchema

  public Schema getSchema()

  Get a reference to the the Schema being used by the XML processor.

  If no schema is being used, null is returned.

  Returns:

  Schema being used or null if none in use

  Throws:

  UnsupportedOperationException - When implementation does not override this method

  Since:

• isXIncludeAware

  public boolean isXIncludeAware()

  Get the XInclude processing mode for this parser.

  Returns:

  the return value of the DocumentBuilderFactory.isXIncludeAware() when this parser was created from factory.

  Throws:

  UnsupportedOperationException - When implementation does not override this method

  Since:

  1.5
