Let's say my XML is like this:
<?xml version="1.0"?>
<lists>
<list
path=".">
<entry
kind="dir">
<name>Assignment1.1</name>
<commit
revision="1668">
<author>netid</author>
<date>2011-09-07T03:03:58.367692Z</date>
</commit>
</entry>
<entry
kind="file">
<name>Assignment1.1/.classpath</name>
<size>397</size>
<commit
revision="1558">
<author>netid</author>
<date>2011-09-06T17:00:52.998920Z</date>
</commit>
.
.
.
</list>
</lists>
And I store it in a SimpleXML object using
$xml_list = simplexml_load_file(dirname(__FILE__).'/svn_list.xml');
How would I access for example, the revision variable containing 1558?
I can't seem to figure it out using a combination of echo and print_r.
SimpleXML uses a set of classes which implement iterators to work through them, so you can loop through each node using foreach, however the easiest way to navigate the XML once it's loaded is by using SimpleXMLElement::xPath(). To get revision 1558, you can make the following call:
$commit = $xml_list->xpath('//list/entry/commit[#revision="1558"]');
This will return you the nodes underneath <commit revision="1558">, and you can then access them from the $commit variable, which extends ArrayObject.
To get the actual content of the <author> element, you must do the following:
print((string)$commit[0]->author);
SimpleXMLElement instances need to be cast to a type to expose their actual values.
Also, if you want to dump the content of $commit to see its child nodes, the easiest way is to call the asXml() method as follows:
print($commit[0]->asXml());
You are facing difficulties because you have error on your XML file , The </entry> tag was not closed.
You could traverse like this.
<?php
$xml='<lists>
<list>
<entry
kind="dir">
<name>Assignment1.1</name>
<commit
revision="1668">
<author>netid</author>
<date>2011-09-07T03:03:58.367692Z</date>
</commit>
</entry>
<entry
kind="file">
<name>Assignment1.1/.classpath</name>
<size>397</size>
<commit
revision="1558">
<author>netid</author>
<date>2011-09-06T17:00:52.998920Z</date>
</commit>
</entry>
</list>
</lists>';
$xml = simplexml_load_string($xml);
foreach ($xml->list->entry[0]->commit->attributes() as $a=>$v)
{
echo $v;
}
OUTPUT :
1668

I am trying to read the value for 3 specific XML nodes (bill_codes, sent_total, clicked_unique_total) I have done a lot of testing and I feel like I need someone with fresh eyes to look at this and help me find out what I no longer see..
I am using the simplexml_load_string function to load the XML into an array..
Here is the code that I have so far:
$xml = simplexml_load_string($content);
echo $xml->methodResponse->item->responseData->message_data->message->bill_codes;
This is the XML that I am using (comes from an API Call so I have no access to modifying/updating the structure of the XML)
<?xml version="1.0" encoding="utf-8"?>
<methodResponse>
<item>
<methodName>
<![CDATA[legacy.message_stats]]>
</methodName>
<responseData>
<message_data>
<message id="2345456">
<message_subject>

Now the above type of XML is stored in variable named $zillow_data
First I load it using SimpleXML using the code
$xml = simplexml_load_string($zillow_data);
Now, I want to get the "message" value as shown in the XML data above.
When I try
foreach($xml->message[0]->text[0] as $response)
It does not work.
When I try something like the below code I get an error in Netbeans IDE
foreach($xml->SearchResults:searchresults[0]->message[0]->text[0] as $response)
The error I get is "unexpected : "
How do I correctly fetch the message in above XML data?
Also how do I parse through all the "result" elements, one by one?
If You use the code:
$xml = simplexml_load_string($string);
while the $string variable contains the XML, the first element <SearchResults:searchresults> becomes the main $xml SimpleXMLElement object, while the child tags <request>, <message> and <response> are its properties.
Thus, forgetting about the undefined namespace warnings, You should be able to do e.g.:
foreach($xml->response->results->result as $result) {
echo (string) $result->zpid;
}
There is only one message with only one text element, thus if You want to echo this one, You should only do:
echo (string) $xml->message->text;
Do a var_dump($xml); to understand the XML structure being transformed into objects and arrays after loading it with SimpleXML.
The problem i was having is the Root XML was being produced every time it writes to the XML.
The Main issue was setting up Child and Defining the Root. From the help of Łza
I now understand the Root XML Node is ignored.
So then you setup and create a Child and then add your content, And example of the correct format is.
$xml = simplexml_load_file('FILENAME.xml'); // Load XML File Need to add IF Statment to create if does not exist
$result = $xml->addchild('Result'); // Ignore Root NODE and Add Child Results
$result->addChild('Time', gmdate('D-M-Y -H:i:s')); // Rest of the below adds Child to Result and outputs results
$result->addChild('Channel', $Site);
$result->addChild('Type', '**');
$result->addChild('Process', $Status);
$result->addChild('SKU', $code->SKU);
$result->addChild('item', $item);
$result->addChild('Status', '$Feedback');
$result->addChild('ErrorID', '$Error');
$result->addChild('Message', '$Message');
$xml->asXml('FILENAME.xml'); //Write to file would be
// All of the above Code is using variables from another part of the script
The output would be
<Root>
<Result>
<Time>Fri-May-2013 -09:15:22</Time>
<Channel>20</Channel>
<Type>**</Type>
<Process>Update</Process>
<SKU>98746524765</SKU>
<Item/>
<Status>Problem</Status>
<ErrorID>999-Error</ErrorID>
<Message>Unknown file format support</Message>
</Result>
<Result>
<Time>Fri-May-2013 -09:15:22</Time>
<Channel>20</Channel>
<Type>**</Type>
<Process>Update</Process>
<SKU>5412254785</SKU>
<Item/>
<Status>Problem</Status>
<ErrorID>123-Error</ErrorID>
<Message>Invalid Item</Message>
</Result>
</Root>
Thanks
Try to use SimpleXMLElement library instead hardcoded xml creation. This is maybe more complicate to use at the begining, but much more safe (I mean avoid possible errors in xml structure when you hardcode the xml) and easy to use when you just get start to use it.
And easy to add/remove nodes, childnodes.
This is an example for your code:
$xml = new SimpleXMLElement('<xml/>');
$data = $xml->addChild('data');
$result = $data->addChild('Result');
$result->addChild('Time', gmdate('D-M-Y -H:i:s'));
$result->addChild('Channel', $SiteID);
// ... and the same way create all your xml nodes.
// if you want add next <result> node witch all elements repeat the code, (or put it in loop if you want more <result> elements):
$result = $data->addChild('Result');
$result->addChild('Time', gmdate('D-M-Y -H:i:s'));
$result->addChild('Channel', $SiteID);
// and after create all nodes save the file:
$xml->asXml('DHError.xml');
above code will create xml:
<xml>
<data>
<Result>
<Time>Fri-May-2013 -12:14:39</Time>
<Channel>data</Channel>
</Result>
<Result>
<Time>Fri-May-2013 -12:14:39</Time>
<Channel>data</Channel>
</Result>
</data>
</xml>
Thats it. Then if you need to load and process the xml it would be easy:
To load the File simply use:
$xml2 = simplexml_load_file('DHError.xml');
// to add new node <Result>:
$resultNext = $xml2->data->addchild('Result');
$resultNext->addChild('Time', gmdate('D-M-Y -H:i:s'));
$resultNext->addChild('Channel', $SiteID);
//and save file
$xml2->asXml('DHError.xml');
this create a xml:
<?xml version="1.0" ?>
<xml>
<data>
<Result>
<Time>Fri-May-2013 -12:27:24</Time>
<Channel>data</Channel>
</Result>
<Result>
<Time>Fri-May-2013 -12:27:24</Time>
<Channel>data</Channel>
</Result>
<Result>
<Time>Fri-May-2013 -12:27:24</Time>
<Channel>data</Channel>
</Result>
</data>
</xml>
I have a XML file. Here is a small version of that.
<?xml version="1.0" encoding="UTF-8"?>

First I would like to know how do we call something like opensearch:totalResults in XML terms.
And I need your help with obtaining following values with PHP.
<opensearch:totalResults>2338</opensearch:totalResults> I need to get 2338 to a PHP variable.
Thank you.
Thank you all for your answers.
I could fix it with following way.
$xml = simplexml_load_string($xmltext);
$val = $xml->xpath('opensearch:totalResults');
echo $val[0];
parse all of this information into PHP using DOM. Ex.
$doc = new DOMDocument;
$doc->loadXML($xml); //$xml is your xml string
echo $doc->getElementsByTagName("totalResults")->item(0)->nodeValue;
For your first question, opensearch:totalResults is the qualified name of a start tag. It is called a qualified name (you might come across this as QName) because it contains the namespace (opensearch) for the tag.
For your second question, you can easily parse your XML into a DOMDocument and then query it for the value of the relevant tag. There are lots of examples on SO and of course on Google; a basic one from PHP.net is here.
Important note: Your current XML document does not contain an XML namespace declaration for the opensearch namespace, and will not parse as a result. You need to add such a declaration by making a modification:
<feed xmlns="http://www.w3.org/2005/Atom" xml:lang="fr"
xmlns:opensearch="http://a9.com/-/spec/opensearch/1.1/">
If you need more powerful querying you can also use XPath. A minimal example would look like:
$doc = new DOMDocument();
$doc->loadXML($xml);
$xpath = new DOMXPath($doc);
$nodes = $xpath->query('//opensearch:totalResults');
foreach ($nodes as $node) {
echo $node->nodeValue;
}
opensearch is a namespace, so you can try to access it like:
$yourXml->children('openSearch', true)->totalResults
Hope it helps
Check this out the exact result in PHP
<?php
$xml ='<?xml version="1.0" encoding="UTF-8"?>
<feed xmlns="http://www.w3.org/2005/Atom" xml:lang="fr">

<opensearch:totalResults>2338</opensearch:totalResults>
<opensearch:itemsPerPage>100</opensearch:itemsPerPage>
<entry>
<category term="Romans" label="Romans"/>
<category term="Aventures" label="Aventures"/>
</entry>
</feed>';
$dom = new DOMDocument();
$dom->loadXML($xml);
$xmlD = simplexml_import_dom($dom);
echo $xmlD->totalResults;
?>
Read your xml file with simplexml_load_file as an object
Then get your variable like this:
$object->{'opensearch:totalResults'};
I am trying to parse an individual element from an XML string using PHP. The issue is that this individual element occurs before the entries start. The XML is below:
<?xml version="1.0" encoding="UTF-8"?>
<feed gd:kind="shopping#products" gd:etag=""lm_25heFT8yiumci9EH1kItJBpg/Sj5O9aXZ82PKpx3N2C3uQYMhNYE"" xmlns="http://www.w3.org/2005/Atom" xmlns:gd="http://schemas.google.com/g/2005" xmlns:openSearch="http://a9.com/-/spec/opensearchrss/1.0/" xmlns:s="http://www.google.com/shopping/api/schemas/2010">
<openSearch:totalResults>64</openSearch:totalResults>
<openSearch:startIndex>1</openSearch:startIndex>
<openSearch:itemsPerPage>25</openSearch:itemsPerPage>
<entry >...</entry>
<entry >...</entry>
</feed>
I am trying to parse out the "64" in the opensearch:totalResults tag. How do I this and assign it to a variable in php? I tried:
$url = 'url of xml feed';
$xml = simplexml_load_file($url);
$entries =$xml->entry[0]->openSearch:totalResults;
// also tried $entries =$xml->openSearch:totalResults;
echo $entries;
but it's not working. Any advice?
You need to register namespace in order to access these nodes:
$xml = simplexml_load_file('file.xml');
$xml->registerXPathNamespace('os', 'http://a9.com/-/spec/opensearchrss/1.0/');
$nodes = $xml->xpath('os:totalResults');
$totalResults = (string)$nodes[0];
You can also use http://it1.php.net/manual/en/simplexmlelement.children.php (using the $ns parameter)
that is less resource intensive.
