Considering this error message please send me a notification when it is fixed. I am using the validator function on my project and need to really get aware when it is gonna get fixed.


An error occurred while cleaning up markup with HTML-Tidy. The reported error was:
Can't locate HTML/Tidy.pm in <at> INC ( <at> INC contains: /etc/perl /usr/local/lib/perl/5.14.2 /usr/local/share/perl/5.14.2 /usr/lib/perl5 /usr/share/perl5 /usr/lib/perl/5.14 /usr/share/perl/5.14 /usr/local/lib/site_perl)

It is unlikely that this is a problem with the checked document, but rather a software or configuration issue with the validator.     



Many thanks,
Katia

>Install w3c-markup-validator

Hi everyone,

Ubuntu Version 12.04 (precise) 64 bits
Noyau Linux 3.2.0-77-generic
GNOME 3.4.2

I've just intalled w3c-markup-validator in local,
with the simply method from Ubuntu repository , no errors

only one thing when I reload or restart Apache it return this:

Syntax error on line 18 of /etc/apache2/mods-enabled/validator.conf:
Invalid command '<Paths', perhaps misspelled or defined by a module not 
included in the server configuration
Action 'configtest' failed.
The Apache error log may have more information.
    ...fail!

so the validator run well in  http://localhost/w3c-validator/

and another question, may be I've not enable one or everal mods, but I 
d'ont know wich of them and how to do that.

Thanks,
best regards,
jmarc

Error message when trying to install W3Validator onto Debian Wheezy.

Hello everyone. 

I just installed w3validator into a Debian Wheezy VPS machine. It looks good, but its not working. I get this message when I try to validate a page:

"
  1.  External Checker not available

    Checking the Document Type of this document requires the help of an external tool which was either not enabled in this validator, or is currently unavailable. Check in the validator's system configuration that HTML5 Validator is enabled and functional.


and validate any site you like. 

The installation was successful, without any errors what I could notice. 

I ran the standard apt-get install w3c-markup-validator

Thanks
Richard Andersson

w3c validator 401 Authorized Required Prompt not working

Good Afternoon All,

I’ve received the below error message when trying to validate a webpage that requires credentials.   The bigger issue is thatW3C Validator didn’t open a prompt window.  I have a local version installed, but is there something I could do to trigger the username/password window to open?

 

Authorization Required

Sorry, I am not authorized to access the specified URL.

The URL you specified, <http://madeupsite.com/>, returned a 401 "authorization required" response when I tried to download it.

You should have been prompted by your browser for a username/password pair; if you had supplied this information, I would have forwarded it to your server for authorization to access the resource. You can use your browser's "reload" function to try again, if you wish.

Of course, you may not want to trust me with this information, which is fine. I can tell you that I don't log it or do anything else nasty with it, and you can download the source code for this service to see what it does, but you have no guarantee that this is actually the code I'm using; you basically have to decide whether to trust me or not :-)

You should also be aware that the way we proxy this authentication information defeats the normal working of HTTP Authentication. If you authenticate to server A, your browser may keep sending the authentication information to us every time you validate a page, regardless of what server it's on, and we'll happily pass that on to the server thereby making it possible for a malicious server operator to capture your credentials.

Due to the way HTTP Authentication works there is no way we can avoid this. We are using some "tricks" to fool your client into not sending this information in the first place, but there is no guarantee this will work. If security is a concern to you, you may wish to avoid validating protected resources or take extra precautions to prevent your browser from sending authentication information when validating other servers.

Also note that you shouldn't use HTTP Basic Authentication for anything which really needs to be private, since the password goes across the network unencrypted.

 

NOTE: Whenever possible, give the address of the document you were checking.

 

 

Thank you,

Aaron L. Butler

Empty namespace example from xml-names11 fails to validate

I tried to validate the following example from section 6.1 of
http://www.w3.org/TR/xml-names11/

(Note that I removed the "illegal" line from the example, not
that it makes a difference)

<?xml version="1.1"?>
<x xmlns:n1="http://www.w3.org">
    <n1:a/>               <!-- legal; the prefix n1 is bound to
http://www.w3.org -->
    <x xmlns:n1="">
        <x xmlns:n1="http://www.w3.org">
            <n1:a/>       <!-- legal; the prefix n1 is bound again -->
        </x>
    </x>
</x>

The example fails with the error:

    Line 4, Column 18: xmlns:n1: Empty XML namespace is not allowed

But this example is from the section that explicitly allows
the empty XML namespace in xmlns: declarations.

So it appears to me that the XML validator is probably at fault here.

Could someone please confirm or deny this, please?

  cheers,
    rog.

Excessive traffic pattern blocked and validation through home page *also* blocked

I am a teacher at a university.  I require my students to validate their
HTML using the W3C validator.  Today students on campus began getting
the message "Excessive traffic pattern blocked."

It is possible that someone has installed a "validate everything"
plugin; it is also possible that 80+ students are validating a page at a
time, but all behind the same gateway: 168.28.180.30.  I understand that
I should not contact the W3C about this because the restriction will be
removed when the pattern stops.

My real problem is this: The error page says, "You should still be able
to use the form interface on the Validator Home Page to check the page
by URL."  I am happy with telling my students they must use that
mechanism and no other.  However, attempting to validate through the
validator home page *also* produces the "Excessive traffic pattern
blocked" message.  Can this be fixed to allow one-at-a-time validations?

Best regards,
Bob Brown, Ph.D.

Problem with Your Validator and SNI

Dear W3-Team,

Your validator has a problem, if he tries to validate any of my 
(sub)domains connected to "deltanet-production.de".

This domain is forced redirected to SSL as security reason and it's only 
available for all clients using SNI but if I want to
check my side there will be the following error:

403 Forbidden
Reason: The client software did not provide a hostname using Server Name 
Indication (SNI), which is required to access this server.

This can be, because your validator isn't able to use/check SNI websides 
or there is a small mistahe in my webservers configuration file.
I hope, that you can help me please, to fix this error.

Kind Regards

Marcel Petzold

[VE][libxml2-205] Confused about validation error: colon are forbidden from entities names 'CWM:ChangeableKind'


Hi,

validating http://hrview.de/measures/index.php/xml/generate/dd5ea5c4-4e48-4e9b-8d44-91a75694ef74 (i have attached the xml) i get many errors of the following kind:

colon are forbidden from entities names 'CWM:ChangeableKind' <!ENTITY % CWM:ChangeableKind '(changeable|frozen|addOnly)'>
Looking in the XMLSpec (esp. the reguarding names): http://www.w3.org/TR/xml11/#NT-Name

The colon (:) is given as valid character.

Am i misunderstanding something?

Thanks,
Friedrich Röhrs
