The speed and memory results from this program should NOT be
used as the basis of parser performance comparison! Real
analytical methods should be used. For better results, perform
multiple document parses within the same virtual machine to
remove class loading from parse time and memory usage.
The "tagginess" measurement gives a rough estimate of the
percentage of markup versus content in the XML document. The
percent tagginess of a document is equal to the minimum amount
of tag characters required for elements, attributes, and
processing instructions divided by the total amount of
characters (characters, ignorable whitespace, and tag characters)
in the document.
Not all features are supported by different parsers.
