My problem is regarding using PHP to access data from a YouTube XML feed. The truncated feed is like this:
<?xml version="1.0" encoding="UTF-8"?>
<entry xmlns="http://www.w3.org/2005/Atom" xmlns:gd="http://schemas.google.com/g/2005" xmlns:media="http://search.yahoo.com/mrss/" xmlns:yt="http://gdata.youtube.com/schemas/2007">
<id>http://gdata.youtube.com/feeds/api/users/AaiKcIfHEzUZl34U980sNA</id>
<yt:firstName>wahbanana</yt:firstName>
<yt:googlePlusUserId>118419787126790739507</yt:googlePlusUserId>
<yt:location>SG</yt:location>
<yt:statistics lastWebAccess="1970-01-01T00:00:00.000Z" subscriberCount="353936" videoWatchCount="0" viewCount="0" totalUploadViews="40288085" />
<media:thumbnail url="http://yt3.ggpht.com/-ukikCGaaWTw/AAAAAAAAAAI/AAAAAAAAAAA/zmPZoDtJEK0/s88-c-k-no/photo.jpg" />
<yt:username>wahbanana</yt:username>
</entry>
I wrote a function to get subscribeCount iinside yt:statistics:
$url = 'http://gdata.youtube.com/feeds/api/users/'.$yt_username;
$xml = file_get_contents($url);
$feed = simplexml_load_string($xml);
$ns=$feed->getNameSpaces(true);
$yt = $entry->children($ns['yt']);
$yt_statistics = $yt->statistics->attributes();
$yt_subscribers = $yt_statistics['subscriberCount'];
But it returns this error:
PHP Fatal error: Call to a member function children() on a non-object in /home/digitali/public_html/wp-content/plugins/OCG-socialintegration/ocg_si.php on line 111
Can someone point out to me what is wrong? Thanks!
you dont have $entry, change to:
$feed = simplexml_load_string($xml);
$ns = $feed->getNamespaces(true);
$yt = $feed->children($ns['yt']);

I'm using $data = file_get_contents('php://input'); when a service is posting xml data to my url. It's giving me an xml string, but I can't figure out how to turn it into a php array. I've tried every solution I can find here on Stack, and it always gives me an empty array. Here's the xml:
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">

I've replaced some words with "blank" for obscurity.
I've tried the recursive xml2array() functions floating about (here, for instance). Returns empty array.
I've tried:
$xml = simplexml_load_string($string, "SimpleXMLElement", LIBXML_NOCDATA);
$array = json_decode(json_encode((array)$xml), TRUE);
Empty array.
What am I missing?
UPDATE
I am now getting this string:
<?xml version="1.0"?>

from this method:
$response = preg_replace("/(<\/?)(\w+):([^>]*>)/", "$1$2$3", $string);
$xml = new SimpleXMLElement($response);
$body = $xml->xpath('//soapBody')[0];
$array = json_decode(json_encode((array)$body), TRUE);
$data = $array['TransferDataString']['data'];
var_dump($data);
But I cannot figure out how to convert that string to a PHP array.
To access the inner data elements...
$xml = simplexml_load_string($data);
$xml->registerXPathNamespace("soap", "http://schemas.xmlsoap.org/soap/envelope/");
$data = $xml->xpath("//soap:Body");
$innerData = (string)$data[0]->TransferDataString->children("urn:www.blank.com:blank:services:2:0:wsdl")->data;
// Convert data to array
$xml2 = simplexml_load_string(trim($innerData));
$array = json_decode(json_encode($xml2), true);
print_r($array);
You can then process the data either as XML, or convert it to an array.
The first part extracts the soap:Body and then it manipulates that to get at the final inner content.
Example:
$dom = new DOMDocument("1.0", "UTF-8");
$dom->preserveWhiteSpace = false;
$dom->loadXml($source);
$xpath = new DOMXPath($dom);
$xpath->registerNamespace("xsd", "http://www.w3.org/2001/XMLSchema");
$xpath->registerNamespace("xsi", "http://www.w3.org/2001/XMLSchema-instance");
$xpath->registerNamespace("soap", "http://schemas.xmlsoap.org/soap/envelope/");
$xpath->registerNamespace("xmlns", "urn:www.blank.com:blank:services:2:0:wsdl");
// Read the data element
$data = $xpath->query('//soap:Body/xmlns:TransferDataString/xmlns:data')->item(0)->nodeValue;
$data = trim($data);
echo $data;
I have a problem composing XML sitemap using simple xml PHP function, having almost equal situation and when sitemap tag, it is not working:
$xml = simplexml_load_string('<?xml version="1.0" encoding="UTF-8"?><sitemapindex xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"></urlset>');
$sitemap = $xml->addChild("sitemap");
$sitemap->addChild("loc", "http://www.example.com/sitemap-1.xml");
Fatal error: Call to a member function addChild() on boolean
This is working reliably:
$xml = simplexml_load_string('<?xml version="1.0" encoding="utf-8"?><urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"></urlset>');
$url = $xml->addChild("url");
$url->addChild("loc", "http://www.example.com/sitemap-2.xml");
Your issue is caused by simple mistake.
(you have - maybe forgot to change - closing tag from urlset to sitemapindex):
$xml = simplexml_load_string('<?xml version="1.0" encoding="UTF-8"?><sitemapindex xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"></urlset>');
Correct:
$xml = simplexml_load_string('<?xml version="1.0" encoding="UTF-8"?><sitemapindex xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"></sitemapindex>');
I am trying to parse XML with PHP. The XML is a response from ebay getsellerlist api, and is structured like so:
<!--?xml version="1.0" encoding="UTF-8"?-->
<getsellerlistresponse xmlns="urn:ebay:apis:eBLBaseComponents">
<timestamp>2016-08-11T14:17:39.869Z</timestamp>
<ack>Success</ack>
<version>967</version>

<galleryurl>url1</galleryurl>
<photodisplay>thumbnail1</pictureurl>
<pictureurl>picture1</pictureurl>
</picturedetails>
</item>
</itemarray>
</getsellerlistresponse>
My php is as follows:
<?
$xml = '<!--?xml version="1.0" encoding="UTF-8"?--><getsellerlistresponse xmlns="urn:ebay:apis:eBLBaseComponents"><timestamp>2016-08-11T14:17:39.869Z</timestamp><ack>Success</ack><version>967</version><build>E967_CORE_APISELLING_17965876_R1</build><itemarray><item><itemid>itemid1</itemid><listingdetails><viewitemurl>itemurl1</viewitemurl></listingdetails><primarycategory><categoryid>categoryid1</categoryid><categoryname>categoryname1</categoryname></primarycategory><title>title1</title><picturedetails><galleryurl>url1</galleryurl><photodisplay>thumbnail1</pictureurl><pictureurl>picture1</pictureurl></picturedetails></item><item><itemid>itemid2</itemid><listingdetails><viewitemurl>itemurl2</viewitemurl></listingdetails><primarycategory><categoryid>categoryid2</categoryid><categoryname>categoryname2</categoryname></primarycategory><title>title1</title><picturedetails><galleryurl>url2</galleryurl><photodisplay>thumbnail2</pictureurl><pictureurl>picture2</pictureurl></picturedetails></item></itemarray></getsellerlistresponse>';
$dom = new DOMDocument();
$dom->loadXML($xml);
$title_nodes = $dom->getElementsByTagName('title');
$titles = array();
foreach ($title_nodes as $node) {
$titles[] = $node->nodeValue;
echo $node->nodeValue;
}
echo $titles[0];
echo count($titles);
?>
When I run it, I get a blank page, no errors, nothing.
If I check $titles length using count(), it comes back as zero.
For some reason it is not getting the title node (or any other nodes) and I can't figure out how to parse the xml string with php and get the node values.
Any help most appreciated, if the question is vague or lacking detail, please let me know and I will correct it.
The XML isn't valid:
Unable to parse any XML input. org.jdom2.input.JDOMParseException: Error on line 2: The element type "photodisplay" must be terminated by the matching end-tag "".
And that's only after you remove the comments in your XML declaration:
<!--?xml version="1.0" encoding="UTF-8"?-->
shoud be
<?xml version="1.0" encoding="UTF-8"?>
Working demo:
<?php
$xml = '<?xml version="1.0" encoding="UTF-8"?>

I have a small requirement where I need to create a XML file on the fly. It was no problem for me to create a normal xml file which would be looking like this:
<?xml version="1.0" encoding="UTF-8"?>
<root>
<item>
<name></name>
</item>
</root>
But my requirement is such that I need to create a XML file whose output is:
<?xml version="1.0" encoding="UTF-8"?>
<root>
<item>
<name url = "C:\htdocs\proj1\source_file1"/>
<name url = "C:\htdocs\proj1\source_file2"/>
<name url = "C:\htdocs\proj1\source_file3"/>
</item>
</root>
I have tried in this fashion:
<?php
$domtree = new DOMDocument('1.0', 'UTF-8');
$domtree->formatOutput = true;
$xmlRoot = $domtree->createElement("root");
$xmlRoot = $domtree->appendChild($xmlRoot);
$item = $domtree->createElement("item");
$item = $xmlRoot->appendChild($item);
$name= $domtree->createElement("name");
$name = $item->appendChild($name);
$sav_xml = $domtree->saveXML();
$handle = fopen("new.xml", "w");
fwrite($handle, $sav_xml);
fclose($handle);
?>
But I wanted to append/add the url="path" to my elements. I have tried declaring variables with url and path but this throws me errors like:
Uncaught exception 'DOMException' with message 'Invalid Character Error'
Any ideas how to approach this problem!
Thanks
You just have to declare that attributes via php DOM:
...
$name= $domtree->createElement("name");
$urlAttribute = $domtree->createAttribute('url');
$urlAttribute->value = 'C:\htdocs\proj1\source_file1';
$name->appendChild($urlAttribute);
$item->appendChild($name);
...
Link to DOMDocument docs
i haven't really worked with xml files before, but now i'm trying to get an xml file into a php array or object.
the xml file looks like this: (it's for translating a web app)
<?xml version="1.0" ?>
<content language="de">
<string name="login">Login</string>
<string name="username">Benutzername</string>
<string name="password">Passwort</string>
</content>
i tried the following:
$xml = new SimpleXMLElement("de.xml", 0, 1);
print_r($xml);
unfortunately, the values of the 'name' attribute are for some reason not in the php object. i'm looking for a way that allows me to retrieve the xml values by the name attribute.
for instance:
$xml['username'] //returns "Benutzername"
how can this be done?
appreciate your help :) cheers!
This one should explain the function to you:
<?php
$xml = simplexml_load_file('de.xml');
foreach($xml->string as $string) {
echo 'attributes: '. $string->attributes() .'<br />';
}
?>
The attributes() method from SimpleXMLElement class will help you - http://de.php.net/manual/en/simplexmlelement.attributes.php
$xmlStr = <<<XML
<?xml version="1.0" ?>
<content language="de">
<string name="login">Login</string>
<string name="username">Benutzername</string>
<string name="password">Passwort</string>
</content>
XML;
$doc = new DomDocument();
$doc->loadXML($xmlStr);
$strings = $doc->getElementsByTagName('string');
foreach ($strings as $node) {
echo $node->getAttribute('name') . ' = ' . $node->nodeValue . PHP_EOL;
}
You can use an xpath expression to get the element with the name you are looking for:
(string)current($xml->xpath('/content/string[#name="username"]'))
