echo simplexml object

Question

This question has two parts.

Part 1. Yesterday I had some code which would echo the entire content of the XML from an RSS feed. Then I deleted it fr

Answer 1

According to the php manual:

$xml = new SimpleXMLElement($string);
.
.
.

then if you want to echo the result:

echo $xml->asXML();

or save the xml to a file:

$xml->asXML('blog.xml');

Answer 2

The simplexml_load_file returns an SimpleXMLElement, so:

print_r($xml);

will show its minor objects and arrays.

After your tweaks you can call $xml->asXML("filename.xml"); as @Tim Withers pointed out.

Answer 3

Part 1: echo $xml->asXML(); - http://www.php.net/manual/en/simplexmlelement.asxml.php

Part 2: php SimpleXML check if a child exists

$html .= "<h3 class='blog'>".($entry->title!=null?$entry->title:'No Title')
    . "<span class='pubDate'> | " .$pubDate . "</span></h3><p class='blog'>" 
    . $entry->content . "</p>";

Note I would probably load the url like this:

$feedUrl = 'http://www.blogger.com/feeds/6552111825067891333/posts/default';
$rawFeed = file_get_contents($feedUrl);
$xml = new SimpleXmlElement($rawFeed);

Based on your comment in regards to part 1, I am not sure if the XML is being loaded completely. If you try loading it this way, it should display all the XML data.

Answer 4

Part 1

This is still not exactly what I wanted, but rather a very tidy and organized way of echoing the xml data:

    $url = "http://www.blogger.com/feeds/6552111825067891333/posts/default";
$xml = simplexml_load_file($url);
echo '<pre>';
print_r($xml);

Part 2

I had to get firephp running so I could see exactly what elements php was encountering when it reached an entry without a blog title. Ultimately it is an empty array. Therefore, the simple:

if(empty($entry->title))

works perfectly. For string comparison, I found that you can simply cast it as a string. For my purposes, that was unnecessary.
