        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.

      • 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:

        Returns:
        the systemid corresponding to the given file.
