errore validazione pagina

**blur** · 14-06-2006, 10:45

ciao,

sto cercando di validare in locale una pagina.
mi da un errore nella prima riga

codice:

Line 1 column 0: character "" not allowed in prolog.

���

nell'editor però nella prima riga non c'è nulla di strano ( mi riferisco ai punti di domanda) e non ci sono righe vuote prima del doctype.

però il validatore mi da la seguente nota:

"The Unicode Byte-Order Mark (BOM) in UTF-8 encoded files is known to cause problems for some text editors and older browsers. You may want to consider avoiding its use until it is better supported."

che cos'è il Unicode Byte-Order Mark (BOM)?

e qual'è il problema?

Puoi postare qui il codice incriminato?

**blur** · 14-06-2006, 11:08

l'errore è nella prima riga:

codice:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">

e uso un charset= UTF-8

codice:

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />

**pierofix** · 14-06-2006, 11:15

Prova a postarci tutto il markup del documento.

**blur** · 14-06-2006, 11:21

ah ok... però posso postare solo la parte dell'header dato che uso le inclusioni delle pagine php
e cmq anche con le altre pagine l'errore è sempre e solo lì.

codice:

    </div>

va bene così?

**pierofix** · 14-06-2006, 11:34

Ma non starai mica validando la pagina con dentro il codice PHP, vero?

Stai validando l'output?

**blur** · 14-06-2006, 11:59

ovvio sto validando l'output, ma in questo caso cosa cambia?

ecco l'output

codice:

[*][img]immagini/point.gif[/img] ελλ[/list]
   </div>
    </div>

etc...il resto del codice..

l'unica cosa di "strano" è che se visualizzo l'output della pagina, ci sono un ventina di righe vuote in alto prima del doctype.... :master:

validatore html
Salve Raga volevo sapere se in giro per il web esista qualche tool che permetta di analizzare e correggere in automatico il codice html.
Io gestisco 5 siti web e in tutti e cinque quando vado a fare la scansione con il servizio di http://validator.w3.org/ mi da errori, ma siccome non ci capisco nulla e devo sbrigarmela da solo vorrei trovare qualcosa che in qualche modo mi aiuti. Grazie anticipatamente!!! Buona navigazione a tutti e complimenti a http://www.html.it
Ciao a presto

**giopalla** · 15-06-2006, 12:01

Se qualcuno mi vuole aiutare il risultato della scansione fatta è questo:
Error Line 46 column 32: required attribute "TYPE" not specified.
<SCRIPT LANGUAGE="JavaScript1.1">
The attribute given above is required for an element that you've used, but you have omitted it. For instance, in most HTML and XHTML document types the "type" attribute is required on the "script" element and the "alt" attribute is required for the "img" element.

Typical values for type are type="text/css" for <style> and type="text/javascript" for <script>.

You have used the attribute named above in your document, but the document type you are using does not support that attribute for this element. This error is often caused by incorrect use of the "Strict" document type with a document that uses frames (e.g. you must use the "Transitional" document type to get the "target" attribute), or by using vendor proprietary extensions such as "marginheight" (this is usually fixed by using CSS to achieve the desired effect instead).

This error may also result if the element itself is not supported in the document type you are using, as an undefined element will have no supported attributes; in this case, see the element-undefined error message for further information.

How to fix: check the spelling and case of the element and attribute, (Remember XHTML is all lower-case) and/or check that they are both allowed in the chosen document type, and/or use CSS instead of this attribute.

✉

Error Line 89 column 23: end tag for element "DIV" which is not open.
</div></td>
The Validator found an end tag for the above element, but that element is not currently open. This is often caused by a leftover end tag from an element that was removed during editing, or by an implicitly closed element (if you have an error related to an element being used where it is not allowed, this is almost certainly the case). In the latter case this error will disappear as soon as you fix the original problem.

If this error occured in a script section of your document, you should probably read this FAQ entry.

You have used the element named above in your document, but the document type you are using does not define an element of that name. This error is often caused by:

incorrect use of the "Strict" document type with a document that uses frames (e.g. you must use the "Frameset" document type to get the "<frameset>" element),
by using vendor proprietary extensions such as "<spacer>" or "<marquee>" (this is usually fixed by using CSS to achieve the desired effect instead).
by using upper-case tags in XHTML (in XHTML attributes and elements must be all lower-case.

Leuca: Complesso ¼/strong>?Case Salento” è il luogo ideale dove
You have used an illegal character in your text. HTML uses the standard UNICODE Consortium character repertoire, and it leaves undefined (among others) 65 character codes (0 to 31 inclusive and 127 to 159 inclusive) that are sometimes used for typographical quote marks and similar in proprietary character sets. The validator has found one of these undefined characters in your document. The character may appear on your browser as a curly quote, or a trademark symbol, or some other fancy glyph; on a different computer, however, it will likely appear as a completely different character, or nothing at all.

Your best bet is to replace the character with the nearest equivalent ASCII character, or to use an appropriate character entity. For more information on Character Encoding on the web, see Alan Flavell's excellent HTML Character Set Issues reference.

This error can also be triggered by formatting characters embedded in documents by some word processors. If you use a word processor to edit your HTML documents, be sure to use the "Save as ASCII" or similar command to save the document without formatting information.

....com<WBR>/exchange/exit.php?id=60837&q<WBR>=821&btn=on">
An entity reference was found in the document, but there is no reference by that name defined. Often this is caused by misspelling the reference name, unencoded ampersands, or by leaving off the trailing semicolon (

. The most common cause of this error is unencoded ampersands in URLs as described by the WDG in "Ampersands in URLs".

Entity references start with an ampersand (&) and end with a semicolon (

. If you want to use a literal ampersand in your document you must encode it as "&" (even inside URLs!). Be careful to end entity references with a semicolon or your entity reference may get interpreted in connection with the following text. Also keep in mind that named entity references are case-sensitive; &Aelig; and æ are different characters.

If this error appears in some markup generated by PHP's session handling code, this article has explanations and solutions to your problem.

Note that in most documents, errors related to entity references will trigger up to 5 separate messages from the Validator. Usually these will all disappear when the original problem is fixed.
