DomDocument->html_dump_mem Dumps the internal XML tree back into a string as HTML


string DomDocument->html_dump_mem ( void )

Creates an HTML document from the dom representation. This function usually is called after building a new dom document from scratch as in the example below.

Example #1 Creating a simple HTML document header


// Creates the document
$doc domxml_new_doc("1.0");

$root $doc->create_element("html");
$root $doc->append_child($root);

$head $doc->create_element("head");
$head $root->append_child($head);

$title $doc->create_element("title");
$title $head->append_child($title);

$text $doc->create_text_node("This is the title");
$text $title->append_child($text);


The above example will output:

<html><head><title>This is the title</title></head></html>

Clarification: DomDocument->dump_mem adds the  <?xml version="1.0"?> header, with some additional options.

header("Content-Type: application/xhtml+xml");
forces xml processing (this can also be a server setting). Idealy, both should be used for serving xhtml, though the <?xml version="1.0"?> may be dropped - on its own, it does not XML processing.

Note that DomDocument->html_dump_mem does not allow you to output valid XHTML, as you need to have valid xml tags for it.  Use DomDocument->dump_mem to output valid XHTML instead.
