## Method Details

### getParserFactory

public static 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 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 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 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 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 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 String getSystemId(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 DocumentBuilder getDocumentBuilder() throws BuildException
Returns a newly created DocumentBuilder.

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