Overriding HTML::StripScripts to allow DDTs (Document Type Declarations)
------------------------------------------------------------------------
A Document Type Declaration is the first line of an HTML (or X-HTML) document
which describes the particular version of HTML that will be used in the
For instance, strict HTML 4.01 has this declaration:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
By default, DTDs are rejected by HTML::StripScripts. If you would like to
accept them, you will need to subclass HTML::StripScripts
(or HTML::StripScripts::Parser) to allow them.
IMPORTANT: More than just allowing them, you should also check the values that
are passed in.
--------------------------------------------------------------------------------
To run the example:
- change to the examples/declaration directory:
cd examples/declaration
- then type:
perl declaration.pl
The example parses the same HTML, first with HTML::StripScripts::Parser, then
with MyStripScripts (a subclass of HTML::StripScripts::Parser) and prints out
the two versions.
No checking of the values is done.
The example script requires HTML::StripScripts::Parser to work.
