Ok, j’ai a peu près compris, c’est juste que je n’arrive pas à corriger mes erreurs.
Voici le début de mon code :
<?xml version="1.0"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="#LANG" lang="#LANG" dir="#LANG_DIR">
<head>
Pour les erreurs de W3C, en voici une legere liste, d’où mon incompréhension des erreurs... vu que c’est du Spip pur et dur
°
“character "#" is not allowed in the value of attribute "xml:lang"
…s="http://www.w3.org/1999/xhtml" xml:lang="#LANG" lang="#LANG" dir="#LANG_DIR">”
°
“character "" not allowed in attribute specification list
”
°
“element "INCLURE" undefined
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 "
" element),
* by using vendor proprietary extensions such as "" or "
" (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).”
Je ne vous met pas tout, car je pense que ce n’est pas nécessaire.
