Get image from XML and display with PHP? - php

Question

I'm trying to use an API with the following XML:
<movies>
<movie>
<images>
<image type="poster" url="http://cf1.imgobject.com/posters/b7a/4bc91de5017a3c57fe00bb7a/i-am-legend-original.jpg" size="original" width="675" height="1000" id="4bc91de5017a3c57fe00bb7a"/>
<image type="poster" url="http://cf1.imgobject.com/posters/b7a/4bc91de5017a3c57fe00bb7a/i-am-legend-mid.jpg" size="mid" width="500" height="741" id="4bc91de5017a3c57fe00bb7a"/>
<image type="poster" url="http://cf1.imgobject.com/posters/b7a/4bc91de5017a3c57fe00bb7a/i-am-legend-cover.jpg" size="cover" width="185" height="274" id="4bc91de5017a3c57fe00bb7a"/>
</images>
</movie>
</movies>
Can someone give me an example of the PHP code I should use to get the image url where size="cover"?
Thanks.

Answer 1

SimpleXML can do this quite, for lack of a better word, simply:
$xml = new SimpleXMLElement($str);
$xpath = $xml->xpath("/movies/movie/images/image[#size = 'cover']");
echo $xpath[0]['url'];

Answer 2

Load the xml with a XML Parser, DOMDocument, SimpleXML etc.
http://se.php.net/manual/en/refs.xml.php
Then you can use XPath to select the image.
http://www.w3schools.com/xpath/xpath_syntax.asp
XPath to grab movie with attribute size = cover
/movies/movie/images/image[#size=cover]
Looks like a good tutorial: http://ditio.net/2008/12/01/php-xpath-tutorial-advanced-xml-part-1/

<?php
$string = <<<XML
<?xml version='1.0'?>
<movies>
<movie>
<images>
<image type="poster" url="http://cf1.imgobject.com/posters/b7a/4bc91de5017a3c57fe00bb7a/i-am-legend-original.jpg" size="original" width="675" height="1000" id="4bc91de5017a3c57fe00bb7a"/>
<image type="poster" url="http://cf1.imgobject.com/posters/b7a/4bc91de5017a3c57fe00bb7a/i-am-legend-mid.jpg" size="mid" width="500" height="741" id="4bc91de5017a3c57fe00bb7a"/>
<image type="poster" url="http://cf1.imgobject.com/posters/b7a/4bc91de5017a3c57fe00bb7a/i-am-legend-cover.jpg" size="cover" width="185" height="274" id="4bc91de5017a3c57fe00bb7a"/>
</images>
</movie>
</movies>
XML;
$xml = simplexml_load_string($string);
foreach($xml->movie->images->image as $image) {
if(strcmp($image['size'],"cover") == 0)
echo $image['url'];
}
?>

Answer 4

$xml = simplexml_load_string($string2);
foreach($xml->movie->images->image as $image) {
if(strcmp($image['size'],"cover"))
// echo $image['url'];
?>
