here is my code
function parsexml($xml)
{
$xmlparse=simplexml_load_string($xml)
var_dump($xmlparse);
}
You won't get all nodes because they use namespaces, for exmple: pl:id. To parse these you could use Xpath. first example grabs all pl:added second one gets media:hash.
You can only use the following if you know the file will always use the same prefix. If not, you have to register the namespace for each simpleXMLElement object you use.
<?
$str = '*your string here*';
$xml = simplexml_load_string($str);
// to get pl:added
foreach($xml->xpath('//media:content') as $element) {
$added = $element->xpath('//pl:added');
}
//output $added
echo "<pre>";
var_dump($added);
// to get media:hash
foreach($xml->xpath('//media:thumbnail') as $element) {
$hash = $element->xpath('//media:hash');
}
//output $hash
echo "<pre>";
var_dump($hash);
?>
When you need to register namespaces you can do the following. First you can var dump the namespaces so you know which url you need to use.
["os"]=>string(36) "http://a9.com/-/spec/opensearch/1.1/" So for os you need that url.
<?
$str = '*your string here*';
$xml = simplexml_load_string($str);
// to get the namespaces uncomment the next 3 lines
// $namespaces = $xml->getNamespaces(true);
// echo "<pre>";
// var_dump($namespaces);
$xml->registerXPathNamespace('media', 'http://search.yahoo.com/mrss/');
foreach($xml->xpath('//media:content') as $element) {
$element->registerXPathNamespace('pl', 'http://xml.theplatform.com/data/object');
$added = $element->xpath('//pl:added');
}
echo "<pre>";
var_dump($added);
$xml->registerXPathNamespace('media', 'http://search.yahoo.com/mrss/');
foreach($xml->xpath('//media:thumbnail') as $element) {
$element->registerXPathNamespace('media', 'http://search.yahoo.com/mrss/');
$hash = $element->xpath('//media:hash');
}
echo "<pre>";
var_dump($hash);
?>

You can use XPath:
$brazil = $usdXML->xpath('/channel/item[targetCurrency="BRL"]');
print($brazil[0]->description . "\n");
print($brazil[0]->pubDate . "\n");
Get category from wordpress rss [php]
Hi i need help to get all categories from rss. This is ex. of my rss feed: <item> <title>Coca-Cola</title> <link>https://www.tralaaa.com/coca-cola/</link> <comments></comments> <pubDate>Fri, 01 Dec 2017 11:36:40 +0000</pubDate> <dc:creator><![CDATA[Admin]]></dc:creator> <category><![CDATA[cat1]]></category> <category><![CDATA[cat2]]></category> <category><![CDATA[cat3]]></category> <category><![CDATA[cat4]]></category> <description><![CDATA[]]></description> <content:encoded><![CDATA[]]></content:encoded> </item> I try with $cat = $item->category(0); but give me the error Call to undefined method SimpleXMLElement::category()
You cant access category using () parenthesis, you need to use [], like this: $xml = new SimpleXMLElement( '<item> <title>Coca-Cola</title> <link>https://www.tralaaa.com/coca-cola/</link> <comments></comments> <pubDate>Fri, 01 Dec 2017 11:36:40 +0000</pubDate> <dc:creator><![CDATA[Admin]]></dc:creator> <category><![CDATA[cat1]]></category> <category><![CDATA[cat2]]></category> <category><![CDATA[cat3]]></category> <category><![CDATA[cat4]]></category> <description><![CDATA[]]></description> <content:encoded><![CDATA[]]></content:encoded> </item>'); $cat_name1 = $xml->category[0]->__toString(); $cat_name2 = $xml->category[1]->__toString(); $cat_name3 = $xml->category[2]->__toString(); $cat_name4 = $xml->category[3]->__toString(); echo "<pre>"; print_r($cat_name1); echo "</pre>"; echo "<pre>"; print_r($cat_name2); echo "</pre>"; echo "<pre>"; print_r($cat_name3); echo "</pre>"; echo "<pre>"; print_r($cat_name4); echo "</pre>"; this will output: you can just: $xml->category->__toString(); it will assume you want the first category.
PHP XML why I can't read the first attribute with SimpleXML?
The XML file I want to read looks like this:
<issues aaa="444" exportTime="Tue Jul 28 23:54:39 CEST 2015">
<issue>
<name>Testing</name>
I use this code:
$simple = file_get_contents('/url/test3.xml');
$test = new SimpleXMLElement($simple);
I can read the issue name children:
echo $test->issue[1]->name;
How can I read issues ExportTime value?
echo $test->issues[exportTime]
doesn't do anything.
Try <?php $str = <<<XML <issues aaa="444" exportTime="Tue Jul 28 23:54:39 CEST 2015"> <issue> <name>Testing</name> </issue> </issues> XML; $xml = new SimpleXMLElement($str); var_dump($xml['exportTime']); ?> OUTPUT object(SimpleXMLElement)[2] public 0 => string 'Tue Jul 28 23:54:39 CEST 2015' (length=29)
Random Number in RSS feed
This is what I currently have for my PHP file:
<?php header("Content-type: text/xml"); ?>
<?php echo "<?xml version=\"1.0\" encoding=\"UTF-8\"?>"; ?>
<rss version="2.0">

That right there is correctly showing one entry in the RSS feed. However, I need it to show 30 entries, each with a random number entered in the three places where NUMBER is shown in the item.
Each RSS item should have a different number between 1 and 2779503 entered in the three places that say NUMBER. I know that PHP has http://php.net/manual/en/function.rand.php but what I don't know how to do is have it loop through 30 random numbers each time the feed is loaded...
<?php
foreach( range( 1, 30 ) as $i ):
$number = mt_rand( 1, 2779503 );
?>
<item>
<title>Website Directory - Page <?php echo $number; ?></title>
<pubDate><?echo date('Y/m/d H:i:s');?></pubDate>
<link>http://www.mywebsite.com/directory/<?php echo $number; ?></link>
<description>New update to page <?php echo $number; ?> in the Website Directory.</description>
</item>

Parsing a foursquare KML venue feed with simpleXML
I am trying to parse a KML venue feed from foursqare with simpleXML but I cannot get the nested-in-desctription venue url. It looks like simpleXML strips it. In detail: The foursqare kml feed looks like this: <kml> <Folder> <name>foursquare checkin history for X</name> <description>foursquare checkin history for X</description> <Placemark> <name>somevenuename</name> <description>#somevenuename- a foursqareshout!</description> <updated>Wed, 02 Nov 11 17:00:05 +0000</updated> <published>Wed, 02 Nov 11 17:00:05 +0000</published> <visibility>1</visibility> <Point> <extrude>1</extrude> <altitudeMode>relativeToGround</altitudeMode> <coordinates>xx.xxxxxx,yy.yyyyyy</coordinates> </Point> </Placemark> etc ... My call to simpleXMl is ... well, simple: $venue_items = simplexml_load_file($venue_kml_file); Any ideas who to preserve the html in description?
They're right. This is invalid XML. However, I wrote a workaround for you using regex. It may be a bit hacky, but you can only make due with what you've been given, so here it is:
$xml_string = <<<XML_STRING
<kml>
<Folder>
<name>foursquare checkin history for X</name>
<description>foursquare checkin history for X</description>
<Placemark>
<name>somevenuename</name>
<description>#somevenuename- a foursqareshout!</description>
<updated>Wed, 02 Nov 11 17:00:05 +0000</updated>

<Point>
<extrude>1</extrude>
<altitudeMode>relativeToGround</altitudeMode>
<coordinates>xx.xxxxxx,yy.yyyyyy</coordinates>
</Point>
</Placemark>
</Folder>
<Folder>

</Placemark>
</Folder>
</kml>
XML_STRING;
preg_match_all( '%<Placemark>(.*?)</Placemark>%s', $xml_string, $placemarks, PREG_SET_ORDER );
for( $x = 0; $x < sizeof($placemarks); $x++ ){
preg_match_all('%<description>(.*?)</description>%s', $placemarks[$x][1], $descriptions, PREG_SET_ORDER );
for( $y = 0; $y < sizeof($descriptions); $y++ ){
echo $descriptions[$y][1];
}
}
Hope that helps...
