Is there any way I can insert an HTML template to existing DOMNode without content being encoded?
I have tried to do that with:
$dom->createElement('div', '<h1>Hello world</h1>');
$dom->createTextNode('<h1>Hello world</h1>');
The output is pretty much the same, with only difference that first code would wrap it in a div. I have tried to loadHTML from string but I have no idea how can I append it's body content to another DOMDocument.
In javascript, this process seems to be quite simple and obvious.
You can use
Example:
// just some setup
$dom = new DOMDocument;
$dom->loadXml('<html><body/></html>');
$body = $dom->documentElement->firstChild;
// this is the part you are looking for
$template = $dom->createDocumentFragment();
$template->appendXML('<h1>This is <em>my</em> template</h1>');
$body->appendChild($template);
// output
echo $dom->saveXml();
Output:
<?xml version="1.0"?>
<html><body><h1>This is <em>my</em> template</h1></body></html>
If you want to import from another DOMDocument, replace the three lines with
$tpl = new DOMDocument;
$tpl->loadXml('<h1>This is <em>my</em> template</h1>');
$body->appendChild($dom->importNode($tpl->documentElement, TRUE));
Using TRUE
as the second argument to importNode
will do a recursive import of the node tree.
If you need to import (malformed) HTML, change loadXml
to loadHTML
. This will trigger the HTML parser of libxml (what ext/DOM uses internally):
libxml_use_internal_errors(true);
$tpl = new DOMDocument;
$tpl->loadHtml('<h1>This is <em>malformed</em> template</h2>');
$body->appendChild($dom->importNode($tpl->documentElement, TRUE));
libxml_use_internal_errors(false);
Note that libxml will try to correct the markup, e.g. it will change the wrong closing </h2>
to </h1>
.
