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

BuildException

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

BuildException

Since:

Ant 1.6

newParserFactory

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

Returns a new parser factory instance.

BuildException

getParser

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

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.

Ant 1.5.2

getDocumentBuilder

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

Returns a newly created DocumentBuilder.

Returns:
