In particular, note that white space around the document element is ignored by the parser.
Sémantique et XHTML | Les petites cases
They are, at this point, in the Document of the aforementioned outer browsing context. The tree construction stage can affect the state of the tokenization stage, and can insert additional characters into the stream. Process the token using the rules for the ” in head ” insertion mode.
After the attributes, or after the tag name if there are no attributes, there may be one or more space characters.
If node is a head element and last is false, then switch the insertion mode to ” in head ” and abort these steps. This handling is, by necessity, spread across both the tokenization stage and the tree construction stage.
Switch to the comment less-than sign bang dash dash state.
The common ancestor is the body element. Text is allowed inside elements, attribute values, and comments. In the following example, the tree construction stage will be called upon to handle a ” p ” start tag token while handling the ” script ” end tag token: Consider the following markup, which for this example we will assume is the document with URL https: For each of the characters in the temporary buffer in the order they were added to the liateemit the character as a character token.
Le langage HTML/Structure de base d’un document HTML
However, if the user agent delays too long to obtain data to determine the encoding, then the cost of the delay could outweigh any performance improvements from the preparse.
When lists end tag token is emitted with its self-closing flag set, that is a parse error. Switch the insertion mode to ” in template “.
There must never be two or more attributes on the same start tag whose names are an ASCII case-insensitive match for each other.
Extra constraints are placed on what is and what is not allowed in text based oiste where the text is to be put, as described in the other sections. Tree structures that do not roundtrip a serialize and reparse step can also be produced by the HTML parser itself, although such cases are typically non-conforming.
Otherwise, treat it as per the “anything else” entry below. Insert an HTML element for the token for which the element entry was created, to obtain new element. Balise there is a template element on the stack of open elementsthen ignore the token. If charset is x-user-definedthen set charset to windows In general preparsing the source to find the encoding improves performance, as it reduces the need to throw away the data structures used when parsing upon finding the encoding information.
In general, moving script elements between Document s is considered a bad practice. This is a simple case, in that the formatting element baliss the b element, and there is no furthest block. If it is true, then the tokenizer must abort the processing of any nested invocations of the tokenizer, yielding control back to the caller.
If this parser has been aborted in the meantime, abort these steps. Let last template be the last template element in the stack of open elementsif any. User agents are therefore encouraged to use the prescan algorithm below as invoked by these steps on the first bytes, but not to stall beyond that.
Implementations must act as if they used the following state machine to tokenize HTML. There are also further restrictions described below. Block the tokenizer for this instance of the HTML parsersuch that the event loop will not run tasks that invoke the tokenizer.
Even though the is attribute governs the creation of a customized built-in elementit is not present during the execution of the relevant custom element constructor ; it is appended in this step, along with all other attributes. Switch the insertion mode to ” after head “. Otherwise, let adjusted insertion location be the appropriate place for inserting a node. This fixes the use of namespaced attributes, in particular XLink. Elements must not contain content that their content model disallows.
Nothing happens if at any time any of the elements in the stack of open dees are moved to a new location in, or removed from, the Document tree. Let element be the result of creating an element given documentlocal namegiven namespacenull, and is. If the stack of open elements does not have a p element in button scopethen this is a parse error ; insert an HTML element for a “p” start tag token with no attributes. If need pragma is null, then jump to the step below labeled Next byte.
The template contents of any template elements. Set the current document readiness to ” interactive ” and the insertion point to undefined. Process the token according to the rules given in the section for parsing tokens in foreign content. Now, if the current node is not a valises element, then this is a parse error.
Let the adjusted insertion location be the appropriate place for inserting a node. Reconsume in the script data escaped state. While the parser is processing a token, it can enable or disable balisse parenting.
Upon receiving the end tag token with the tag name “b”, the ” adoption agency algorithm ” is invoked.
