Thank you very much for your help.

The APIs which our project uses are listed as follows. 
(Sorry that I just grep them from source code, but the class and method 
name should be obvious)
If you find that we used Xerces-Perl inappropreately somewhere or have 
some better suggestion, please kindly let us know.


DOM parsing:
------------

1. my $parser = XML::Xerces::XercesDOMParser->new();

2. $parser->setDoNamespaces(1);

3. $parser->setCreateEntityReferenceNodes(1);

4. $parser->setDoSchema(1);

5. $parser->setErrorHandler(...);

6. $parser->setValidationScheme($XML::Xerces::AbstractDOMParser::Val_Auto);

7. $parser->parse(XML::Xerces::MemBufInputSource->new($xmlString));

8. $parser->parse($xmlFile);

9. my $doc = $parser->getDocument();

SAX parsing:
------------

1. my $parser = XML::Xerces::XMLReaderFactory::createXMLReader();

2. $parser->setFeature("$XML::Xerces::XMLUni::fgSAX2CoreNameSpaces", 1);

3. $parser->setFeature("$XML::Xerces::XMLUni::fgSAX2CoreValidation",1);

4. $parser->setFeature("$XML::Xerces::XMLUni::fgXercesDynamic", 1);

5. $parser->setFeature("$XML::Xerces::XMLUni::fgXercesSchema", 1);

6. $parser->setErrorHandler(...);

7. $parser->setContentHandler(...);

8. $parser->parse(XML::Xerces::MemBufInputSource->new($xmlString));

9. $parser->parse(XML::Xerces::LocalFileInputSource->new($xmlFile));

XML Serialization:
------------------

1. my $domImpl = 
     XML::Xerces::DOMImplementationRegistry::getDOMImplementation('LS');

2. my $writer = $domImpl->createDOMWriter();

3. $writer->canSetFeature('format-pretty-print',1);

4. $writer->setFeature('format-pretty-print',1);

5. my $target = XML::Xerces::MemBufFormatTarget->new();

6. $writer->writeNode($target, $doc);

7. $target->getRawBuffer();
