How can I extract all text from XML data using PHP (i.e. SimpleXmlElement)?
Here\'s my XML data:
$data = \'Report of the <org reg=\"International Foo and Bar Conference, 5th\">Fifth International Foo and Bar Confe
<script async src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script>
<ins class="adsbygoogle"
style="display:block"
data-ad-client="ca-pub-5408099190056760"
data-ad-slot="7305827575"
data-ad-format="auto"
data-full-width-responsive="true"></ins>
<script>
(adsbygoogle = window.adsbygoogle || []).push({});

<p>the docs for <code>__toString</code> on SimpleXMLElement says: "Returns text content that is directly in this element. Does not return text content that is inside this element's children."</p>
<p>The <code>asXML</code> method seems to be better for what you want: http://php.net/manual/en/simplexmlelement.asxml.php</p>
<p>it will return a string:</p>
<p><code>"<?xml version="1.0"?>
<title>Report of the <org reg="International Foo and Bar Conference, 5th">Fifth International Foo and Bar Conference</org>, <org>Foobar Hall</org>, London, July 14 to 16, 1908.</title>
"</code></p>

<p>You'd have to strip out the opening XML tag though, but it's much better.</p>

<p>This can be easily done in DOM. DOM element nodes have a property $textContent, that will return its text content including all descendant text nodes.</p>
<pre><code>$document = new DOMDocument();
$document->loadXml($data);
var_dump($document->documentElement->textContent);
</code></pre>
<p>Output:</p>
<pre><code>string(99) "Report of the Fifth International Foo and Bar Conference, Foobar Hall, London, July 14 to 16, 1908."
</code></pre>
<p>If you do not have the element node already in a variable, it will be more convenient to use XPath.</p>
<pre><code>$document = new DOMDocument();
$document->loadXml($data);
$xpath = new DOMXpath($document);
var_dump($xpath->evaluate('string(/title)'));
</code></pre>
<p>It is even possible to convert a <code>SimpleXMLElement</code> into a DOM element node.</p>
<pre><code>$element = new SimpleXMLElement($data);
$node = dom_import_simplexml($element);
var_dump($node->textContent);
</code></pre>
