DOMDocument::loadHTMLFile — Load HTML from a file
The function parses the HTML document in the file named
filename
. Unlike loading XML, HTML does not have
to be well-formed to load.
This function parses the input using an HTML 4 parser. The parsing rules of HTML 5, which is what modern web browsers use, are different. Depending on the input this might result in a different DOM structure. Therefore this function cannot be safely used for sanitizing HTML.
As an example, some HTML elements will implicitly close a parent element when encountered. The rules for automatically closing parent elements differ between HTML 4 and HTML 5 and thus the resulting DOM structure that DOMDocument sees might be different from the DOM structure a web browser sees, possibly allowing an attacker to break the resulting HTML.
filename
The path to the HTML file.
options
Bitwise OR
of the libxml option constants.
If an empty string is passed as the filename
or an empty file is named, a warning will be generated. This warning
is not generated by libxml and cannot be handled using libxml's error handling
functions.
Anche se un HTML malformato potrebbe essere caricato con successo, questa funzione può generare errori E_WARNING
quando incontra un markup errato. le funzioni di gestione errore di libxml possono essere usate per gestire questi errori.
