I had hoped that they were more clear... Any suggestions as to how to
make them more useful are welcome.
Let's pick apart DOMCount.pl for a bit:
my $parser = XML::Xerces::DOMParser->new();
$parser->setValidationScheme ($validate);
$parser->setDoNamespaces ($namespace);
$parser->setCreateEntityReferenceNodes(1);
$parser->setDoSchema ($schema);
First we create the parser object, then we set whatever parse flags we
need. Don't confuse ValidationScheme with scheme, it can take three
values:
* $XML::Xerces::DOMParser::Val_Always
* $XML::Xerces::DOMParser::Val_Never
* $XML::Xerces::DOMParser::Val_Auto
If you've set DoSchema, it will use a schema to validate the document,
if you haven't it will expect a DTD.
my $error_handler = XML::Xerces::PerlErrorHandler->new();
$parser->setErrorHandler($error_handler);
It's always a good idea to use an error handler. Otherwise parsing
just stops with no error message, not too friendly.
$parser->parse (XML::Xerces::LocalFileInputSource->new($file));
Currently, only one of the parse() methods is available, so you need
to create an InputSource. parse() does all the work.
my $doc = $parser->getDocument ();
my $element_count = $doc->getElementsByTagName("*")->getLength();
Once you're done, getDocument() will give you the Document object,
with which you can begin picking apart the information...
HTH,
jas.
