W3C::XHTML::HTMLCompatChecker - The W3C XHTML/HTML Compatibility Checker
Checks XHTML documents (online or local) for compatibility with legacy HTML User-Agents.
W3C::XHTML::HTMLCompatChecker can be used to check whether some content written in XHTML can safely be served as HTML (text/html) to User-Agents that can process HTML, but not XML.
W3C::XHTML::HTMLCompatChecker
text/html
This checker follows the guidelines for compatibility found in the XHTML 1.0 Specification, for XHTML 1.0 content served "as HTML" (i.e with the media type text/html). http://www.w3.org/TR/xhtml1/#guidelines
This checker also has a "any xhtml" mode, where any XHTML document, regardless of its media type, will be checked.
use W3C::XHTML::HTMLCompatChecker; my $checker = W3C::XHTML::HTMLCompatChecker->new(); my @messages = $checker->check_uri("http://... ");
$checker = W3C::XHTML::HTMLCompatChecker->new
$checker->check_uri("http://... ")
Check an online XHTML 1.0 document, served as "text/html" media type, for incompatibilities with legacy HTML.
$checker->check_uri("http://... ", any_xhtml=>1)
Check any online XHTML document, regardless of doctype and media type for incompatibilities with legacy HTML.
$checker->check_content("<!DOCTYPE html ...")
Check an XHTML 1.0 document (as string), for incompatibilities with legacy HTML.
$checker->check_content("<!DOCTYPE html ...", any_xhtml=>1)
Check any XHTML document (as string), for incompatibilities with legacy HTML.
The checker will return an array of hashes, each hash representing an error/warning/info, as follows:
Severity of message: Error, Warning, Info, Hint or Abort
line where observation was made
(may be undefined for Abort messages)
column/offset where observation was made
Explanation of the message
Identifier for the relevant compatibility guideline
Example: 1 is http://www.w3.org/TR/xhtml1/#C_1
Title of the relevant guideline
Example: Element Minimization and Empty Element Content
If the any_xhtml parameter is not set, the checker will return a single Abort message if:
any_xhtml
the document is not served as text/html (N/A for check_content), or
check_content
the document is not identifiable as XHTML 1.0, or
the document is not well-formed XML
If the any_xhtml parameter is set, the checker will return a single Abort message if the document is not well-formed XML.
