public ValidatingXMLParser()

Method Detail

main

public static void main(java.lang.String[] args)

Parse an XML parser using a validating parser. The DTD http://ptolemy.eecs.berkeley.edu/xml/dtd/MoML_1.dtd is replaced with the value of MoMLParser.MoML_1.dtd.

Parameters:

args - A single element array that names the xml file to be parsed. The file should have <configure>...<configure> removed. One workaround is to remove the configure tags with a script before validating, see $PTII/ptolemy/moml/test/removeconfigure. See also http://ptolemy.eecs.berkeley.edu/ptolemyII/ptIIfaq.htm#MoML

parse

public static void parse(java.lang.String fileName)

Parse an XML parser using a validating parser. The DTD http://ptolemy.eecs.berkeley.edu/xml/dtd/MoML_1.dtd is replaced with the value of MoMLParser.MoML_1.dtd.

Parameters:

fileName - The xml file to be parsed. The file should have <configure>...<configure> removed.

Throws:

java.lang.Throwable - If the XML is invalid XML.
