Dom_Document_Helper::get_root_html │ public │ WC 1.0

Serializes every top-level node of the loaded fragment back to HTML.

The document is loaded with LIBXML_HTML_NOIMPLIED (no implicit html/body wrapper), so the top-level nodes are the fragment's own roots. Useful for reading back what remains after elements have been removed.

Method of the class: Dom_Document_Helper{}

No Hooks.

Returns

string.

Usage

$Dom_Document_Helper = new Dom_Document_Helper();
$Dom_Document_Helper->get_root_html(): string;
