Ok i am using a simple XML function to get some information from a remote database, this works fine, however it returns all of the information in an xml format, and what i want to do is just show the results of one field, so for example below is the result i want to display
<product id="9" name="Computer screwdriver" datasheet="" packshot=""/>
and below is my code
$file = 'http://computers.mysite.co.uk/vrm.xml?apikey=**********&vid=Check&vrm='.$reg;
if(!$xml = simplexml_load_file($file))
exit('Failed to open '.$file);
print_r($id);
UPDATE
ok so i have now changed my code to this:
$data = simplexml_load_file("http://test.mysite.co.uk/test.xml? apikey=********&vid=app&vrm='.$reg;");
print $data->computers->computer->products->product->name;
The xml structure is here:
<computers sid="1234">
<computer id="253406" name="computer name)" model_group="Microsofth" start_year="2005" end_year="2009">
<system id="969623" capacity="3.4"/>
<developer id="64" name="intel"/>
<machine id="8" name="P" etype="P"/>
<products>
<product id="9" name="computer screwdriver" datasheet="" packshot=""/>
<product id="16" name="Screwdriver Crosshead" datasheet="" packshot=""/>
</products>
</computer>
</computers
What i want to do is to return the name of the product in the first line of products only, in this case id = 9.
At the moment the way the code isn't showing any results though if i change it to show all results it does, so the problem is just trying to filter that one result out.
Any help would be appreciated.
Thanks
$data->xpath("you_selector")
and don't forget
header("Content-Type:text/xml");

I am parsing through the following XML file:

</y:NodeLabel>
</y:GenericNode>

</node>
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 stored below mention XML in a table(MS-SQL DB).

Now I want to fetch this record by php using the following code :
$query = "Select xml_rec from tbl_node where UserId = 12691";
$result = sqlsrv_query($this->db->conn_id, $query);
$row = sqlsrv_fetch_object($result);
//// OR
$row = sqlsrv_fetch_array($result , SQLSRV_FETCH_ASSOC);
echo $row['xml_rec'];
I am getting the following wrong XML . Please note the blank tags.

How to fix this to show the proper XML ? Thanks for your valuable time.
You don't really use any xml-processing functions here, you simply retrieve a string and display it. The most likely cause of your problem was that some time when you stored this data in your DB, the empty tags got processed from the
<tag></tag>
form into
<tag />
form.
You can check this by connecting to your DB directly (without PHP) and running the query manually.
In any case, as lad2025 pointed out, the two ways of writing empty tags are equivalent so it shouldn't matter for your application.
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">
<response type="success">
<message>Complete</message>
<data>
<status>
<mount>/stream</mount>
<sid>1</sid>
<listenercount>31</listenercount>
<genre>Blues</genre>
<url>http://www.websiteurl.com</url>
<title>Streams Name</title>
<currentsong>Artist Name - Track Name</currentsong>
<bitrate>128</bitrate>
<sourceconnected>1</sourceconnected>
<codec>audio/mpeg</codec>
<displayname>/stream</displayname>
<serverstate>1</serverstate>
<appstate>
<sctrans2>1</sctrans2>
</appstate>
<sourcestate>1</sourcestate>
<reseller/>
<useserver>1</useserver>
<ipaddress>11.11.111.111</ipaddress>
<port>8031</port>
<proxy>0</proxy>
<servertype>ShoutCast2</servertype>
<sourcetype>sctrans2</sourcetype>
</status>
<mountpoints>
<row>
<mount>/stream</mount>
<sid>1</sid>
<listenercount>31</listenercount>
<genre>Blues</genre>
<url>http://www.websiteurl.com</url>
<title>Stream Title Name</title>
<currentsong>Artist Name - Track Name</currentsong>
<bitrate>128</bitrate>
<sourceconnected>1</sourceconnected>
<codec>audio/mpeg</codec>
<displayname>/stream</displayname>
</row>
<row>
<mount>/live</mount>
<sid>2</sid>
<listenercount>0</listenercount>
<genre/>
<url/>
<title/>
<currentsong/>
<bitrate>0</bitrate>
<sourceconnected>0</sourceconnected>
<codec/>
<displayname>/live</displayname>
</row>
</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".
The full example:
$buffer = <<<XML
<centovacast version="3.1.2" host="host.net">

</centovacast>
XML;
$array = simplexml_load_string($buffer)->xpath('//listenercount');
$sum = array_sum(array_map('intval', $array));
var_dump($sum);
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 know there is already a lot of topics about simpleXML and PHP, but I need help with an specific xml code.

I need a foreach to get the data from each "product" like this:
<?
$feedUrl = 'url to xml file';
$rawFeed = file_get_contents($feedUrl);
$xml = simplexml_load_string($rawFeed);
foreach ($item ...????? ?)
{
}
How can I do this foreach to get the data. I tried all that I know without success.
Thanks.
First, you need <?xml version="1.0" encoding="UTF-8"?> as the first line in your XML, otherwise it's not valid. Then, and this will help you debug all sorts of things over your coding career, try this line:
echo "<pre>".print_r($xml,true)."</pre>";
That will give you the exact layout of the object you get back from the simplexml_load_string() call. From there, since you have a visual of the object layout, you should be able to figure out how to parse it. Incidentally, in your case, I think you'd need to do something like:
foreach($xml->vitrine as $element) {
// your code goes here
}
It seems PHP gets rid of evrything after the whitespace, because product id was changed to just product. Anyway here's the code.
<?php
$v = <<<ABC
