POInserting a new line using DOM

Body
copied!<p>I'm attempting to insert a new node into an XML document. I'm using simpleXML for most of the parsing but for this piece I need to use DOM. This is the function i'm using to make the addition</p> <pre><code>function simplexml_insert_after(SimpleXMLElement $sxe, SimpleXMLElement $insert, SimpleXMLElement $target) { $target_dom = dom_import_simplexml($target); $target_dom->formatOutput = true; $target_dom->preserveWhiteSpace = false; $insert_dom = $target_dom->ownerDocument->importNode(dom_import_simplexml($insert), true); if ($target_dom->nextSibling) { return $target_dom->parentNode->insertBefore($insert_dom, $target_dom->nextSibling); } else { return $target_dom->parentNode->appendChild($insert_dom); } } </code></pre> <p>And calling it like this:</p> <pre><code>$meta2 = new SimpleXMLElement("<meta/>"); $meta2->addAttribute('name', 'subject'); $meta2->addAttribute('value', $doc_id); $target = current($my_xml->xpath('//meta[last()]')); simplexml_insert_after($my_xml, $meta2, $target); </code></pre> <p>My Problem is that its inserting the new node immediately after the target rather than on a new line so the resulting XML looks like this:</p> <pre><code><meta content="a" name="ap-category"/> <meta content="bx" name="ap-format"/><meta name="subject" value="urn:blah"/> </code></pre> <p>When I'd like it to look like this:</p> <pre><code><meta content="a" name="ap-category"/> <meta content="bx" name="ap-format"/> <meta name="subject" value="urn:blah"/> </code></pre> <p>I've tried changing preserveWhiteSpace to true, but it did not help. How do i go about adding a new line before inserting that node?</p> <p><strong>edit</strong> Here is the fix that worked:</p> <pre><code> function simplexml_insert_after(SimpleXMLElement $sxe, SimpleXMLElement $insert,SimpleXMLElement $target) { $target_dom = dom_import_simplexml($target); $target_dom->formatOutput = true; $target_dom->preserveWhiteSpace = false; $insert_dom = $target_dom->ownerDocument->importNode(dom_import_simplexml($insert), true); if ($target_dom->nextSibling) { $result = $target_dom->parentNode->insertBefore($insert_dom, $target_dom->nextSibling); $target_dom->parentNode->insertBefore($target_dom->ownerDocument->createTextNode("\n"), $result); return $result } else { return $target_dom->parentNode->appendChild($insert_dom); } } </code></pre>
