Notes and Potential Issues

The following notes and warnings highlight missing or conflicting information which caused the validator to perform some guesswork prior to validation, or other things affecting the output below. If the guess or fallback is incorrect, it could make validation results entirely incoherent. It is highly recommended to check these potential issues, and, if necessary, fix them and re-validate the document.

  1. Warning Unable to Determine Parse Mode!

    The validator can process documents either as XML (for document types such as XHTML, SVG, etc.) or SGML (for HTML 4.01 and prior versions). For this document, the information available was not sufficient to determine the parsing mode unambiguously, because:

    • the MIME Media Type (text/html) can be used for XML or SGML document types
    • No known Document Type could be detected
    • No XML declaration (e.g <?xml version="1.0"?>) could be found at the beginning of the document.
    • No XML namespace (e.g <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en">) could be found at the root of the document.

    As a default, the validator is falling back to SGML mode.

  2. Warning No DOCTYPE found! Checking with default HTML 4.01 Transitional Document Type.

    No DOCTYPE Declaration could be found or recognized in this document. This generally means that the document is not declaring its Document Type at the top. It can also mean that the DOCTYPE declaration contains a spelling error, or that it is not using the correct syntax.

    The document was checked using a default "fallback" Document Type Definition that closely resembles “HTML 4.01 Transitional”.

    Learn how to add a doctype to your document from our FAQ.

  3. Info No Character encoding declared at document level

    No character encoding information was found within the document, either in an HTML meta element or an XML declaration. It is often recommended to declare the character encoding in the document itself, especially if there is a chance that the document will be read from or saved to disk, CD, etc.

    See this tutorial on character encoding for techniques and explanations.

Validation Output: 3 Errors

  1. Error Line 1, Column 1: no document type declaration; implying "<!DOCTYPE HTML SYSTEM>" 
    <html>

    ✉

    The checked page did not contain a document type ("DOCTYPE") declaration. The Validator has tried to validate with a fallback DTD, but this is quite likely to be incorrect and will generate a large number of incorrect error messages. It is highly recommended that you insert the proper DOCTYPE declaration in your document -- instructions for doing this are given above -- and it is necessary to have this declaration before the page can be declared to be valid.

  2. Warning Line 3, Column 41: NET-enabling start-tag requires SHORTTAG YES 
    <meta name="robots" content="noarchive" />

    ✉

    For the current document, the validator interprets strings like <FOO /> according to legacy rules that break the expectations of most authors and thus cause confusing warnings and error messages from the validator. This interpretation is triggered by HTML 4 documents or other SGML-based HTML documents. To avoid the messages, simply remove the "/" character in such contexts. NB: If you expect <FOO /> to be interpreted as an XML-compatible "self-closing" tag, then you need to use XHTML or HTML5.

    This warning and related errors may also be caused by an unquoted attribute value containing one or more "/". Example: <a href=http://w3c.org>W3C</a>. In such cases, the solution is to put quotation marks around the value.

  3. Error Line 3, Column 42: character data is not allowed here 
    <meta name="robots" content="noarchive" />

    ✉

    You have used character data somewhere it is not permitted to appear. Mistakes that can cause this error include:

    • putting text directly in the body of the document without wrapping it in a container element (such as a <p>aragraph</p>), or
    • forgetting to quote an attribute value (where characters such as "%" and "/" are common, but cannot appear without surrounding quotes), or
    • using XHTML-style self-closing tags (such as <meta ... />) in HTML 4.01 or earlier. To fix, remove the extra slash ('/') character. For more information about the reasons for this, see Empty elements in SGML, HTML, XML, and XHTML.
  4. Warning Line 4, Column 44: NET-enabling start-tag requires SHORTTAG YES 
    <meta name="googlebot" content="nosnippet" />

  5. Error Line 5, Column 7: end tag for "HEAD" which is not finished 
    </head>

    ✉

    Most likely, you nested tags and closed them in the wrong order. For example <p><em>...</p> is not acceptable, as <em> must be closed before <p>. Acceptable nesting is: <p><em>...</em></p>

    Another possibility is that you used an element which requires a child element that you did not include. Hence the parent element is "not finished", not complete. For instance, in HTML the <head> element must contain a <title> child element, lists require appropriate list items (<ul> and <ol> require <li>; <dl> requires <dt> and <dd>), and so on.
