PHP DOM XML not printing out line breaks after tags

So my problem is that the tags in my xml file aren't being properly formatted with line breaks after them when I use the php XML DOM parser to save.

$xdoc = new DOMDocument();
$xdoc->formatOutput = true;
$xdoc->preserveWhiteSpace  = false;
$xdoc->load($file);

$new_topic=$xdoc->createElement("topicref", "");
$new_topic->setAttribute("navtitle", $new_node);

$new_topichead=$xdoc->createElement("topichead", "");
$new_topichead->setAttribute("navtitle", $parent_node->getAttribute("navtitle"));
$new_topichead->appendChild($new_topic);
$parent_node->parentNode->replaceChild($new_topichead, $parent_node);

$xdoc->save($file);

Here's a snippet of my output:

<topichead>
    <topichead navtitle="blarg blarg"><topicref navtitle="another blarg blarg" href="another blarg blarg"></topicref></topichead>
</topichead>

This is just the ending of my file, but for the tag i'm replacing - the topichead navtitle="blarg blarg", with the appended topicref, it gets tacked on next to it rather than going to the next line. And I can't read it like this.

As you see above I have tried " $xdoc->formatOutput = true; $xdoc->preserveWhiteSpace = false;"

but these don't seem to work - they format with the tabs, but it's not giving me the right line breaks.

Thanks =)

It's a common issue, very annoying. This is a bit brute-force, but it should work:

// Reload XML to cause format output and/or preserve whitespace to take effect
$xdoc->loadXML($xdoc->saveXML());

$xdoc->save($file);
