Method Detail

### getParserFactory

    public static javax.xml.parsers.SAXParserFactory getParserFactory()
                                                               throws BuildException

  Returns the parser factory to use. Only one parser factory is ever created by this method and is then cached for future use.

  Returns:
    a SAXParserFactory to use.
  Throws:
    `BuildException` - on error.
  Since:
    Ant 1.5

### getNSParserFactory

    public static javax.xml.parsers.SAXParserFactory getNSParserFactory()
                                                                 throws BuildException

  Returns the parser factory to use to create namespace aware parsers.

  Returns:
    a SAXParserFactory to use which supports manufacture of namespace aware parsers.
  Throws:
    `BuildException` - on error.
  Since:
    Ant 1.6

### newParserFactory

    public static javax.xml.parsers.SAXParserFactory newParserFactory()
                                                               throws BuildException

  Returns a new parser factory instance.

  Returns:
    the parser factory.
  Throws:
    `BuildException` - on error.
  Since:
    Ant 1.5

### getParser

    public static org.xml.sax.Parser getParser()
                                        throws BuildException

  Returns a newly created SAX 1 Parser, using the default parser factory.

  Returns:
    a SAX 1 Parser.
  Throws:
    `BuildException` - on error.
  Since:
    Ant 1.5

    `getParserFactory()`

### getXMLReader

    public static org.xml.sax.XMLReader getXMLReader()
                                              throws BuildException

  Returns a newly created SAX 2 XMLReader, using the default parser factory.

  Returns:
    a SAX 2 XMLReader.
  Throws:
    `BuildException` - on error.
  Since:
    Ant 1.5
  See Also:
    `getParserFactory()`

### getNamespaceXMLReader

    public static org.xml.sax.XMLReader getNamespaceXMLReader()
                                                       throws BuildException

  Returns a newly created SAX 2 XMLReader, which is namespace aware

  Returns:
    a SAX 2 XMLReader.
  Throws:
    `BuildException` - on error.
  Since:
    Ant 1.6
  See Also:
    `getParserFactory()`

### getSystemId

    public static java.lang.String getSystemId(java.io.File file)

  This is a best attempt to provide a URL.toExternalForm() from a file URL. Some parsers like Crimson choke on uri that are made of backslashed paths (ie windows) as it is does not conform URI specifications.

  Parameters:
    `file` - the file to create the system id from.
  Returns:
    the systemid corresponding to the given file.
  Since:
    Ant 1.5.2

### getDocumentBuilder

    public static javax.xml.parsers.DocumentBuilder getDocumentBuilder()
                                                                throws BuildException

  Returns a newly created DocumentBuilder.

  Returns:
    a DocumentBuilder.
  Throws:
    `BuildException` - on error.
