I've got an XML output that produces code such as:
<loadavg>
<one>0.00</one>
<five>0.02</five>
<fifteen>0.02</fifteen>
</loadavg>
<!-- whostmgrd -->
I would like to know how I can use PHP to parse that file, and grab the contents between <one>,<five> and <fifteen>. It would be useful if it were to be stored as $loadavg[1] an array.
Thanks
Yep, SimpleXML can do it:
$xml = <<<XML
<loadavg>
<one>0.00</one>
<five>0.02</five>
<fifteen>0.02</fifteen>
</loadavg>
XML;
$root = new SimpleXMLElement($xml);
$loadavg = array((string) $root->one,
(string) $root->five,
(string) $root->fifteen);
print_r($loadavg);
prints
Array (
[0] => 0.00
[1] => 0.02
[2] => 0.02
)
The easiest way to parse an XML file is using SimpleXML. It should be easy to load the XML as a SimpleXML object and get the data using that. If you could post a sample of a complete XML file I could offer some sample code.

I am parsing XML strings using simplexml_load_string(), but I noticed that i don't get the name of the very first tag.
For example, I have these two xml strings:
$s = '<?xml version="1.0" encoding="UTF-8"?>
<ParentTypeABC>
<chidren1>
<children2>1000</children2>
</chidren1>
</ParentTypeABC>
';
$t = '<?xml version="1.0" encoding="UTF-8"?>
<ParentTypeDEF>
<chidren1>
<children2>1000</children2>
</chidren1>
</ParentTypeDEF>
';
NOTICE that they are nearly identical, the only difference being that one has the first node as <ParentTypeABC> and the other as <ParentTypeDEF>
then I just convert them to SimpleXML objects:
$o = simplexml_load_string($s);
$p = simplexml_load_string($t);
but then i have two equal objects, none of them having the "top" node's name appearing, either ParentTypeABC or ParentTypeDEF (I examine the objects using print_r()):
// with top node "ParentTypeABC"
SimpleXMLElement Object
(
[chidren1] => SimpleXMLElement Object
(
[children2] => 1000
)
)
// with top node "ParentTypeDEF"
SimpleXMLElement Object
(
[chidren1] => SimpleXMLElement Object
(
[children2] => 1000
)
)
So how I am supposed to know the top node's name? If I parse unknown XMLs and I need to know what's the top node name, what can I do?
Is there an option in simplexml_load_string() I could use?
I know there are MANY ways to parse XML's with PHP, but I'd like it to be as simple as posible, and to get a simple object or array I could navigate easily.
I made a simple example here to fiddle with.
SimpleXML has a getName() method.
echo $xml->getName();
This should return the name of the respective node, no matter if root or not.

I'm working with a web service that is submitting an HTTP POST to a PHP page as follows:
FORM/POST PARAMETERS:
None
HEADERS:
Content-Type: text/xml
BODY:
<?xml version="1.0"?>
<mogreet>
<event>message-in</event>
<type>command_sms</type>
<campaign_id>12345</campaign_id>
<shortcode>123456</shortcode>
<msisdn>15552345678</msisdn>
<carrier><![CDATA[T-Mobile]]></carrier>
<carrier_id>2</carrier_id>
<message><![CDATA[xxxx testing]]></message>
</mogreet>
I need to be able to convert each of the XML elements into PHP variables so I can update a database. I've never had to work with an incoming POST with XML data before and not sure where to starT - I am familiar with processing incoming GET/POST requests but not raw xml.
I think you'll need to use $HTTP_RAW_POST_DATA. After that then you could use SimpleXMLElement as #ChristianGolihardt suggested.
Note that HTTP_RAW_POST_DATA is only available if the always_populate_raw_post_data setting has been enabled in php.ini. Otherwise, it may be easiest to do this:
$postData = file_get_contents("php://input");
...
$xml = new SimpleXMLElement($postData);
...
This will eliminate all the SimpleXMLElement objects and return your array:
from an xml string:
<?php
$xml='<?xml version="1.0"?>
<mogreet>
<event>message-in</event>
<type>command_sms</type>
<campaign_id>12345</campaign_id>
<shortcode>123456</shortcode>
<msisdn>15552345678</msisdn>
<carrier><![CDATA[T-Mobile]]></carrier>
<carrier_id>2</carrier_id>
<message><![CDATA[xxxx testing]]></message>
</mogreet>';
$xml = simplexml_load_string($xml);
$xml_array = json_decode(json_encode((array) $xml), 1);
print_r($xml_array);
?>
from an xml file:
$xml = simplexml_load_file("mogreet.xml");
$xml_array = json_decode(json_encode((array) $xml), 1);
print_r($xml_array);
output:
Array
(
[event] => message-in
[type] => command_sms
[campaign_id] => 12345
[shortcode] => 123456
[msisdn] => 15552345678
[carrier] => Array
(
)
[carrier_id] => 2
[message] => Array
(
)
)
Take a look at SimpleXMLElement:
http://php.net/manual/de/class.simplexmlelement.php
$xmlstr = $_POST['key'];
$xml = new SimpleXMLElement($xmlstr);
//work with $xml like this:
$event = $xml->mogreet->event;
You can see the key if you do this:
print_r($_POST);
Most times, we work with this kind of api, we want to log it, because we can not see it:
$debugFile = 'debug.log'
file_put_contents($debugFile, print_r($_POST, true), FILE_APPEND);
Take also a look at the Answer from Matt Browne, for getting Raw Input.
I've come across a weird but apparently valid XML string that I'm being returned by an API. I've been parsing XML with SimpleXML because it's really easy to pass it to a function and convert it into a handy array.
The following is parsed incorrectly by SimpleXML:
<?xml version="1.0" standalone="yes"?>
<Response>
<CustomsID>010912-1
<IsApproved>NO</IsApproved>
<ErrorMsg>Electronic refunds...</ErrorMsg>
</CustomsID>
</Response>
Simple XML results in:
SimpleXMLElement Object ( [CustomsID] => 010912-1 )
Is there a way to parse this in XML? Or another XML library that returns an object that reflects the XML structure?
That is an odd response with the text along with other nodes. If you manually traverse it (not as an array, but as an object) you should be able to get inside:
<?php
$xml = '<?xml version="1.0" standalone="yes"?>
<Response>
<CustomsID>010912-1
<IsApproved>NO</IsApproved>
<ErrorMsg>Electronic refunds...</ErrorMsg>
</CustomsID>
</Response>';
$sObj = new SimpleXMLElement( $xml );
var_dump( $sObj->CustomsID );
exit;
?>
Results in second object:
object(SimpleXMLElement)#2 (2) {
["IsApproved"]=>
string(2) "NO"
["ErrorMsg"]=>
string(21) "Electronic refunds..."
}
You already parse the XML with SimpleXML. I guess you want to parse it into a handy array which you not further define.
The problem with the XML you have is that it's structure is not very distinct. In case it does not change much, you can convert it into an array using a SimpleXMLIterator instead of a SimpleXMLElement:
$it = new SimpleXMLIterator($xml);
$mode = RecursiveIteratorIterator::SELF_FIRST;
$rit = new RecursiveIteratorIterator($it, $mode);
$array = array_map('trim', iterator_to_array($rit));
print_r($array);
For the XML-string in question this gives:
Array
(
[CustomsID] => 010912-1
[IsApproved] => NO
[ErrorMsg] => Electronic refunds...
)

what i want to do is : i have an CRM API which produce data in xml format,
i am using DOMDocument() to fetch the data into pieces. The problem is when i tried to load the data like : $dom->loadXML($data);
i got the error :
DOMDocument::loadXML() [domdocument.loadxml]: Input is not proper UTF-8
i google i got an alternative solution to use with file_get_contents() but still i am getting warning like:
here is the code that i am using to fetch the xml data:
$text = file_get_contents(stripslashes(utf8_decode($data)));
$doc = new DOMDocument();
$doc->loadXML($text);
and here i put my XML return data, not complete but just a small piece:
<?xml version="1.0" encoding="utf-8"?>
<whmcsapi version="5.0.3">
<action>getticket</action>
<result>success</result>
<ticketid>5767</ticketid>
<tid>409865</tid>

can anyone please tell me where is the problem? or any alternative ??
Okay, so let's strip down the problem. If $data contains invalid UTF-8, you should be thinking how to make it valid; one way (not sure if that works for you) is with utf8_encode() rather than utf8_decode() (which is used to turn UTF-8 into ISO-8859-1):
$doc = new DOMDocument();
$doc->loadXML(utf8_encode($data));
Otherwise you will need to find out which part of the text includes the bad input. I'll see what I can come up with.
Resources
Ensuring valid utf-8 in PHP
you can try simplexml_load_file php function..
$xml = simplexml_load_file("addinsrss.xml");
echo "<pre>";print_r($xml);echo "</pre>";
If you already have the xml source then dont pass it to FGC. Pass it directly to domDocument.
Or you can also use simplexml_load_string(),
<?php
$xml = '<?xml version="1.0" encoding="utf-8"?>
<whmcsapi version="5.0.3">
<action>getticket</action>
<result>success</result>
<ticketid>5767</ticketid>
<tid>409865</tid>
<c>NwLldOG6</c>
<deptid>2</deptid>
<deptname>Technical</deptname>
<userid>27476</userid>
</whmcsapi>
';
$xml = simplexml_load_string($xml);
print_r($xml);
/*
SimpleXMLElement Object
(
[#attributes] => Array
(
[version] => 5.0.3
)
[action] => getticket
[result] => success
[ticketid] => 5767
[tid] => 409865
[c] => NwLldOG6
[deptid] => 2
[deptname] => Technical
[userid] => 27476
...
...
)
*/
echo $xml->tid; //409865
?>
Or directly use $xml = simplexml_load_file('http://example.com/somexml.xml'); to load from an external url.
I have an xml file
<?xml version="1.0" encoding="utf-8"?>
<xml>
<events date="01-10-2009" color="0x99CC00" selected="true">
<event>
<title>You can use HTML and CSS</title>
<description><![CDATA[This is the description ]]></description>
</event>
</events>
</xml>
I used xpath and and xquery for parsing the xml.
$xml_str = file_get_contents('xmlfile');
$xml = simplexml_load_string($xml_str);
if(!empty($xml))
{
$nodes = $xml->xpath('//xml/events');
}
i am getting the title properly, but iam not getting description.How i can get data inside
the cdata
SimpleXML has a bit of a problem with CDATA, so use:
$xml = simplexml_load_file('xmlfile', 'SimpleXMLElement', LIBXML_NOCDATA);
if(!empty($xml))
{
$nodes = $xml->xpath('//xml/events');
}
print_r( $nodes );
This will give you:
Array
(
[0] => SimpleXMLElement Object
(
[#attributes] => Array
(
[date] => 01-10-2009
[color] => 0x99CC00
[selected] => true
)
[event] => SimpleXMLElement Object
(
[title] => You can use HTML and CSS
[description] => This is the description
)
)
)
You are probably being misled into thinking that the CDATA is missing by using print_r or one of the other "normal" PHP debugging functions. These cannot see the full content of a SimpleXML object, as it is not a "real" PHP object.
If you run echo $nodes[0]->Description, you'll find your CDATA comes out fine. What's happening is that PHP knows that echo expects a string, so asks SimpleXML for one; SimpleXML responds with all the string content, including CDATA.
To get at the full string content reliably, simply tell PHP that what you want is a string using the (string) cast operator, e.g. $description = (string)$nodes[0]->Description.
To debug SimpleXML objects and not be fooled by quirks like this, use a dedicated debugging function such as one of these: https://github.com/IMSoP/simplexml_debug
This could also be another viable option, which would remove that code and make life a little easier.
$xml = str_replace("<![CDATA[", "", $xml);
$xml = str_replace("]]>", "", $xml);
