<?php
$xml = new DOMDocument();
$xml->loadXML('
<a>
<b>test</b>
</a>
');

$temp = $xml->createElement('b');
$temp->appendChild($xml->createTextNode('test'));
$xml->firstChild->appendChild($temp);

echo '<pre>';
echo htmlspecialchars($xml->saveXML());
echo '</pre>';

?>

I'd like for this to be able to return this:

<a>
<b>test</b>
<b>test</b>
</a>

Instead, it produces this:

<a>
<b>test</b>
<b>test</b></a>

ie. the indentation convention that I'm using isn't being used by
saveXML(). Setting $xml->preserveWhiteSpace and $xml->formatOutput to
true doesn't seem to help.

Any ideas as to what - if anything - I can do?

I don't think this is going to help your cause, but maybe it is
because you are not including \n. To me, this looks just fine though :)

You want preserveWhiteSpace = false and formatOutput = true (I know,
it's weird. But that's how it seems to work.) I think these options
also must be set directly after creating the new DOMDocument:

$xml = new DOMDocument;
$xml->preserveWhiteSpace = false;
$xml->formatOutput = true;

// do whatever you do

echo $xml->saveXML(); //output is indented

Maybe not so weird, now that I think about it. preserveWhiteSpace =
true tells it to preserve whitespace text nodes to avoid changing the
meaning of the document. Indenting the document does in fact add
whitespace text nodes, which is a far cry from preserving them.

Settings formatOutput before loading indeed solved the problem, or, =

strangely anough, feeding it a string without ANY whitespace outside tag=
s =

(so '<a><b>test</b></a>').
