Question

How do I insert HTML into a PHP DOM object?

Answer 1

+1 A:

loadHTML works just fine.

<?php
$dom = new DOMDocument();
$dom->loadHTML("<font color='red'>Hey there mrlanrat!</font>");
echo $dom->saveHTML();
?>

which outputs Hey there mrlanrat! in red.

or

<?php
$dom = new DOMDocument();
$bodyHTML = "here is the body, a nice body I might add";
$dom->loadHTML("<body> " . $bodyHTML . " </body>");
// this would even work as well.
// $bodyHTML = "<body>here is the body, a nice body I might add</body>";
// $dom->loadHTML($bodyHTML);
echo $dom->saveHTML();
?>

Which outputs:

here is the body, a nice body I might add and inside of your HTML source code, its wrapped inside body tags.

Will this allow me to append $DOM to a larger DOM Document?

If you are asking if you have two DOMDocument's, `$dom1` and `$dom2` could you add one into the other? The answer is no, at least not to my knowledge.

Well, I need the ability to add my body code to my head and html DOM object.

mrlanrat 2010-02-12 22:38:57

You can, as long as your body code is a string, ie. `$body = "<body><strong>this is a message for the content of my body</strong></body>"` if thats what you were referring to. If I am misunderstanding something, just correct me so I can help you further.

You can use `createElement` among other DOMDocument functions and load it into your DOMDocument.

Anthony Forloney 2010-02-12 23:21:42

`createElement` converts the data into entities.

If I had a better idea on what you'd like to achieve, I could try to demo it for you.

Answer 2

+1 A:

You use the DOMDocumentFragment objec to insert arbitrary HTML chunks into another document.

$dom = new DOMDocument();
@$dom->loadHTML($some_html_document); // @ to suppress a bajillion parse errors

$frag = $dom->createDocumentFragment(); // create fragment
$frag->appendXML($some_other_html_snippet); // insert arbitary html into the fragment

$node = // some operations to find whatever node you want to insert the fragment into

$node->appendChild($frag); // stuff the fragment into the original tree

Answer 3

+1 A:

I spent a lot of time working on Anthony Forloney's answer, But I cannot seem to get the html to append to the body without it erroring.

@Mark B: I have tried doing that, but as I said in the comments, it errored on my html.

I forgot to add the below, my solution:

I decided to make my html object much simpler and to allow me to do this by not using DOM and just use strings.
