I am parsing through the following XML file:

I am interested in only a handful of attributes, namely the node id, data key which I am able to get with the code below. However, when I move into the y: namespace I get nothing.
xmlparser.php
<?php
$xml = simplexml_load_file("testxml.xml")
or die("Error: Cannot create object - check that the XML file exists and is
not corrupted"); print_r($xml);
echo $xml->node[0]['id']; // This works
echo $xml->node[0]->data[0]['key']; // This works
echo $xml->children('y', true)->GenericNode->attributes()->configuration; // Nothing
echo $xml->children('y', true)->GenericNode->NodeLabel; // Nothing
?>
I've read through previous answers on similar issues, based on which I adopted the children approach. However I can't get this to work, and I have no idea how to implement some of the other approaches such as declaring namespaces and the xpath approach.
Any help would be greatly appreciated.
That's because y:GenericNode isn't direct child of the root element, so you shouldn't be accessing it directly from $xml :
$xml->node->data->children('y', true)->GenericNode->attributes()->configuration;

I have done a bit of searching on this, but am just not sure I am searching for the right thing. Examples and things I have found have just confused me and possibly sent me in the wrong direction.
I am trying to figure out a php while statement, or if statement to return the results of XML output. The thing is the row/section I need may not always be the same number of results returned. For example there are ShoutCast streams, some have 1 mount point, and some have 3 mount points. Each mount point can have a different amount of listeners tuned in to that particular mount.
My Goal: To get the integer from all mount points returned in the XML, add them together to make a grand total of listeners.
The XML
<centovacast version="3.1.2" host="host.net">

</mountpoints>
</data>
</response>
</centovacast>
So on the above I know how to pull the listeners for each mount individually using the following code.
$countlisteners->response->data->mountpoints->row[0]->listenercount;
That gives me the result for the first mount, and switching the 0 to a 1 gives me the second mount, so on and so forth.
What I need is for php that will count how many of those mounts exist, and assign each result to a variable I can then use to add together to get a grand total. Is there a way to do this?
What about doing something like this?
$countlisteners = simplexml_load_file('http://urltoxml.com');
foreach($countlisteners->response->data->mountpoints->row->listenercount as $result){
$total = $result;
echo $total;
}
You can use DOMDocument for extracting all mountpoint tags
<?php
$xml="Your xml document content here";
$dom = new DOMDocument;
$dom->loadXML($xml);
$books = $dom->getElementsByTagName('mountpoints');
foreach ($mountpoints as $mountpoints) {
echo $mountpoints->nodeValue;
//you can add your count variable here
//nodeValues can be assigned to varables
}
?>
I figured it out. So simplistic, yet hard to figure out.
$total = 0;
foreach($countlisteners->response->data->mountpoints->row as $result){
$total += $result->listenercount;
$items++;
}
echo $total;
You normally do that with Xpath. It's a query language for XML documents.
You're interested in all listenercount elements, the Xpath expression for these elements could be as simple as:
//listenercount
When you now use SimpleXML to parse the document, the following line of code gives you three SimpleXMLElements inside an array that represent the three values you want to create the sum of:
$array = simplexml_load_string($buffer)->xpath('//listenercount');
As you need the sum of the integer values of these three elements, it can be easily processed with array_map and array_sum:
$sum = array_sum(array_map('intval', $array));
And this gives you in $sum what you're looking for:
var_dump($sum); # int(62)
I hope this sheds you some light why it's often better to get the information you're looking for with an xpath query from the document instead of writing many lines of code to traverse the document "on your own".

$buffer = <<<XML

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)

No need to include the parent, just start with the ->item:
echo $xml->item->responseData->message_data->message->bill_codes;
Sample Output
This is my XML file named: full.xml
I need your help. I need a PHP script that open "full.xml"
and only display all values of the nodes that have .email
Example of the Output I want:
sales#company1.com
sales#company2.com
sales#company3.com
Thanks! I will thank you so much!
EDIT
$Connect = simplexml_load_file("full.xml");
return $Connect->table[0]->*.email;
The design of your XML is not very smart. With this xpath expression, you select all nodes with .email at the end of their name:
$xml = simplexml_load_string($x); // assume XML in $x
$results = $xml->xpath("//*[substring(name(),string-length(name())-" . (strlen('.email') - 1) . ") = '.email']");
--> result is an array with the selected nodes.
BTW: if you have any chance of CHANGING the structure of the XML, AVOID combining information within node names like <company1.email>, but do it like this:
...
<companies>
<company id="1">
<email>info#company1.com</email>
<tel>+498988123456</tel>
<name>somename</name>
</company>
<company id="2">
<email>info#company2.com</email>
<tel>+498988123457</tel>
<name>someothername</name>
</company>
</companies>
....
It will be much easier to read and parse.
I am retrieving some similar XML from the Yahoo API -
<ResultSet version="1.0">
<Error>0</Error>
<ErrorMessage>No error</ErrorMessage>
<Locale>us_US</Locale>
<Quality>99</Quality>
<Found>1</Found>
<Result>
<quality>99</quality>
<latitude>51.501690</latitude>
<longitude>-0.125442</longitude>
<offsetlat>51.501690</offsetlat>
<offsetlon>-0.125442</offsetlon>
<radius>500</radius>
<name>51.501690392606974, -0.1254415512084961</name>
<woeid>26352062</woeid>
</Result>
</ResultSet>
How would I go about accessing the child woeid for example?
I can access quality, longitude etc but I am a little unsure as to how to access a child of a child - is this even the correct terminology?
Any help appreciated.
Thanks
<?php
$xml = simplexml_load_file("XML.xml");
//echo woeid
echo $xml->Result->woeid;
?>
That's just an easy example of how to do it with the xml-file you provided.
You might also run into files where there's more than one <Result> child, in which case you can access them all like this:
<?php
$xml = simplexml_load_file("XML.xml");
//echo all woeid's
foreach($xml->Result as $result) {
echo $result->woeid;
}
?>

The aim is adding a child straight under the document root node and "pushing" the "original" children under the new child:

This php script does that
<?php
header("Content-type: text/xml");
// Create dom document
$doc = new DOMDocument();
$doc->load("myfile.xml");
$doc->preserveWhiteSpace = false;
$doc->formatOutput = true;
// Get first child (blabla)
$blablaNode = $doc->firstChild;
// Crete magic element to hold all children in blabla
$magicElement = $doc->createElement('magic');
while($blablaNode->hasChildNodes()) {
// Remove child from blablaNode and append it into magicElement
$magicElement->appendChild($blablaNode->removeChild($blablaNode->firstChild));
}
// Append magicElement to blablaNode
$magicElement = $blablaNode->appendChild($magicElement);
echo $doc->saveXML();
?>
however the output is

</blabla:sometag>
</magic>
</blabla>
So every node (that is in the "default" namespace) has "blaba" prefix attached to it
<blabla:title />
How to avoid that?
When inspecting the ongoings if changing the PHP to
while($blablaNode->hasChildNodes()) {
$removedChild = $blablaNode->removeChild($blablaNode->firstChild);
echo "(prefix for removed:".$removedChild->prefix.")";
$magicElement->appendChild($removedChild);
echo "(prefix for added:".$magicElement->lastChild->prefix.")";
}
echo is ...(prefix for removed:)(prefix for added:)(prefix for removed:)(prefix for added:default)...
Many thanks in advance!
P.S. This is sequel to this question thus "Or maybe someone has a much better solution in general for achieving the desirable result [adding magic node and pushing everything in it]" still applies...
Indeed, if "putting default namespace declaration first", as Josh Davis notes, the lookup prefix goes away. +1. But that's it as in the output...
...
<metadata xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
xmlns:cc="http://creativecommons.org/ns#">
...
... the declarations still are there.
A clarification. I'm not the creator of those XML docs. Therefore checking the position of default namespace declaration... even if implemented it still wouldn't give the desirable result. And even if those declarations added by libxml should be there by standard, my task is not to validate conformance, but
- simply put all original childnodes, intact in their content (declarations, names values, attributes etc.), under that extra newly created container.
When you append those children, I guess that libxml looks for the first namespace declaration for "http://www.w3.org/2000/blabla" and finds "blabla". Now if you put your default namespace declaration first, it will find that the default namespace works and it will not prefix those nodes with blabla.

Update
The issue is entirely cosmetic, but if you want to remove redundant namespace declarations, you can dump and reload your XML:
$xml = $doc->saveXML();
$doc = new DOMDocument;
$doc->loadXML($xml, LIBXML_NSCLEAN);
echo $doc->saveXML();
Attention if you reuse the $doc variable, it doesn't mean that stuff like $blablaNode will remain functional, it won't. The new $doc is a new document.
Oh, and it will also clean up redundant namespaces from the original document, possibly breaking that "keeping it intact" rule.
Oh, and I forgot to mention that you have to explicitely declare which namespace <magic/> is to be created into:
$magicElement = $doc->createElementNS('http://www.w3.org/2000/blabla', 'magic');
