WebService::Validator::HTML::W3C::Error - Error messages from the W3Cs online Validator DESCRIPTION
This is a wee internal module for WebService::Validator::HTML::W3C. It has three methods: line, col and msg which return the line number, column number and the error that occured at that location in a validated page. If you are using the soap output then you get additional information in the msgid and explanation methods. SEE ALSO

WebService::Validator::CSS::W3C - Interface to the W3C CSS Validator SYNOPSIS
use WebService::Validator::CSS::W3C; my $css = "p { color: not-a-color }"; my $val = WebService::Validator::CSS::W3C->new; my $ok = $val->validate(string => $css); if ($ok and !$val->is_valid) { print "Errors: "; printf " * %s ", $_->{message} foreach $val->errors } DESCRIPTION
This module is an interface to the W3C CSS Validation online service <http://jigsaw.w3.org/css-validator/>, based on its SOAP 1.2 support. It helps to find errors in Cascading Style Sheets. The following methods are available: my $val = WebService::Validator::CSS::W3C->new my $val = WebService::Validator::CSS::W3C->new($ua) my $val = WebService::Validator::CSS::W3C->new($ua, $url) Creates a new WebService::Validator::CSS::W3C object. A custom LWP::UserAgent object can be supplied which is then used for HTTP communication with the CSS Validator. $url is the URL of the CSS Validator, "http://jigsaw.w3.org/css-validator/validator" by default. my $success = $val->validate(%params) Validate a style sheet, takes %params as defined below. Either "string" or "uri" must be supplied. Returns a true value if the validation succeeded (regardless of whether the style sheet contains errors). string => $css A style sheet as a string. It is currently unlikely that validation will work if the string is not a legal UTF-8 string. If a string is specified, the "uri" parameter will be ignored. Note that "GET" will be used to pass the string to the Validator, it might not work with overly long strings. uri => $uri The location of a style sheet or a HTML/XHTML/SVG document containing or referencing style sheets. medium => "print" The medium for which the style sheet should apply, one of "aural", "braille", "embossed", "handheld", "print", "screen", "tty", "tv", and "presentation". A special value "all" can also be specified. The default is "undef" in which case the CSS Validator determines a value; this would currently be as if "all" had been specified. profile => "css3" The CSS Version or profile to validate against, legal values are "css1", "css2", "css21", "css3", "svg", "svgbasic", "svgtiny", "mobile", "atsc-tv", and "tv". A special value "none" can also be used. The default is "undef" in which case the CSS Validator determines a default. This would currently behave as if "css2" had been specified. warnings => 2 An integer 0 - 10 that determines how many warning messages you want to get back from the CSS Validator, 0 means no warnings, 10 would give most warnings, but is currently effectively the same as 1. The defaut is "undef" in which case the CSS Validator determines a default value; this is expected to be as if 2 had been specified. language => "de" The desired language of the supposedly human-readable messages. The string will passed as an "Accept-Language" header in the HTTP request. The CSS Validator currently supports "en", "de", "fr", "ja", "nl", "zh", and "zh-cn". my $success = $val->success Same as the return value of "validate()". my $is_valid = $val->is_valid Returns a true value if the last attempt to "validate()" succeeded and the validator reported no errors in the style sheet. my $num_errors = $val->errorcount returns the number of errors found for the checked style sheet. Get the details of the errors with $val->errors (see below). my @errors = $val->errors Returns a list with information about the errors found for the style sheet. An error is a hash reference; the example in the synopsis would currently return something like ( { context => 'p', property => 'color', expression => { start => '', end => 'not-a-color' } errortype => 'parse-error', message => 'not-a-color is not a color value', line => 0, } ) my $num_warnings = $val->warningcount returns the number of warnings found for the checked style sheet. Get the details of each warning with $val->warnings (see below). my @warnings = $val->warnings Returns a list with information about the warnings found for the style sheet. This is currently of limited use as it is broken, see <http://www.w3.org/Bugs/Public/show_bug.cgi?id=771> for details. @@example my $ua = $val->user_agent my $ua = $val->user_agent($new_ua) The LWP::UserAgent object you supplied to the constructor or a custom object created at construction time you can manipulate. # set timeout to 30 seconds $val->user_agent->timeout(30); You can also supply a new object to replace the old one. my $uri = $val->validator_uri my $uri = $val->validator_uri($validator_uri) Gets or sets the URI of the validator. If you did not specify a custom URI, "http://jigsaw.w3.org/css-validator/validator" by default. my $response = $val->response The HTTP::Response object returned from the last request. This is useful to determine why validation might have failed. if (!$val->validate(string => $css)) { if (!$val->response->is_success) { print $val->response->message, " " } } my $uri = $val->request_uri The URI object used for the last request. my $som = $val->som The SOAP::SOM object for the last successful deserialization, check the return value of "validate()" or "success()" before using the object. BUGS
This module uses the SOAP interface for the W3C CSS validatom, which still has a number of bugs, tracked via W3C's Bugzilla, <http://www.w3.org/Bugs/Public/>. Please report bugs in the W3C CSS Validator to www-validator-css@w3.org or enter them directly in Bugzilla (see above). Please report bugs in this module via RT, <http://rt.cpan.org/>. NOTE
This module is not directly associated with the W3C. Please remember that the CSS Validator is a shared resource so do not abuse it: you should sleep between requests, and consider installing the Validator locally, see <http://jigsaw.w3.org/css-validator/DOWNLOAD.html>. AUTHOR
