I'm trying to get the entry->id and entry->cap:parameter->value for every entry in the RSS feed.... below is the code I'm using. It is displaying the id correctly however it is not displaying the value field.... please help.
$url = 'http://alerts.weather.gov/cap/us.php?x=1';
$cap = simplexml_load_file($url);
foreach($cap->entry as $entry){
echo 'ID: ', $entry->id, "\n";
echo 'VTEC: ', $entry->children('cap', true)->parameter->value, "\n";
echo "<hr>";
}
Thanks for the help in advance.
The <value> element is not in the same namespace as <cap:parameter>:
<cap:parameter>
<valueName>VTEC</valueName>
<value>/O.CON.KMPX.FL.W.0012.000000T0000Z-110517T1800Z/</value>
</cap:parameter>
So you have to call children() again.
Code (demo)
$feed = simplexml_load_file('http://alerts.weather.gov/cap/us.php?x=1');
foreach ($feed->entry as $entry){
printf(
"ID: %s\nVTEC: %s\n<hr>",
$entry->id,
$entry->children('cap', true)->parameter->children()->value
);
}

I need help with this XML located here.
I want get attributes JMENO and HLASY_PROC_1KOLO of the KANDIDAT element:
What I've tried so far:
$xml = simplexml_load_file("https://volby.cz/pls/prez2018/vysledky");
foreach($xml as $item) {
echo $item['CR'],"<br>";
}
See this playground for an example:
$xml = simplexml_load_file("https://volby.cz/pls/prez2018/vysledky");
foreach($xml->CR->KANDIDAT as $item) {
$jmeno = $item->attributes()['JMENO'];
$hlasy = $item->attributes()['HLASY_PROC_1KOLO'];
echo $jmeno, ' : ', $hlasy, '<br />';
}
I'm trying to display values from this xml feed:
http://www.scorespro.com/rss/live-soccer.xml
In my PHP code I have the following loop but it does not display the results on my page:
<?php
$xml = simplexml_load_file("http://www.scorespro.com/rss/live-soccer.xml");
echo $xml->getName() . "<br>";
foreach($xml->children() as $item)
{
echo $item->getName() . ": " . $item->name . "<br>";
}
?>
For some reason it only shows:
rss
channel:
I'm fairly new to how XML works so any help would be much appreciated.
You can get actual data from $xml->channel->item so use like below
$items = $xml->channel->item;
foreach($items as $item) {
$title = $item->title;
$link = $item->link;
$pubDate = $item->pubDate;
$description = $item->description;
}
DEMO.
you can use below code
$dom = new DOMDocument;
$dom->loadXML($url);
if (!$dom) {
echo 'Error while parsing the document';
exit;
}
$xml = simplexml_import_dom($dom);
$data = $xml->channel->item;
how to retrieve both instances of element in an xml file
here is how i have been getting the others
$LargeImage = $xml->Items->Item->LargeImage->URL;
$author = $xml->Items->Item->ItemAttributes->Author;
echo ($author);
however for $author, there are 2 authors and the element is like this
Items->Item->ItemAttributes->
<Author>Ralph Bravaco</Author>
<Author>Shai Simonson</Author>
so my current code is only able to get back the first author
Try this:
foreach($xml->Items->Item->ItemAttributes->Author as $author) {
echo (string)$author.'<br>';
}
It will echo all authors irrespective of no. of authors.
$xml = new SimpleXMLElement($string);
$result = $xml->xpath('/Items/Item/ItemAttributes/Author');
while(list( , $node) = each($result)) {
echo $node,"\n";
}
I think you are asking for this --
echo $author = $xml->Items->Item->ItemAttributes->Author[0];
echo $author = $xml->Items->Item->ItemAttributes->Author[1];

These are player sales from a browser game. I want to save some fields from these sales. I am fetching that xml with curl and storing on my server. Then do the following:
$xml_str = file_get_contents('salespage.xml');
$xml = new SimpleXMLElement($xml_str);
$items = $xml->xpath('*/transfer');
print_r($items);
foreach($items as $item) {
echo $item['buyerTeamname'], ': ', $item['sellerTeamname'], "\n";
}
The array is empty and i cant seem to get anything from it. What am i doing wrong?
There is no reason to use cURL or XPath for that. You can do
$url = 'http://www.managerleague.com/export_data.pl?data=transfers&output=xml&hide_header=0';
$transfers = new SimpleXMLElement($url, NULL, TRUE);
foreach($transfers->transfer as $transfer) {
printf(
"%s transfered from %s to %s\n",
$transfer->playerName,
$transfer->sellerTeamname,
$transfer->buyerTeamname
);
}
Live Demo
You forgot a slash in your xpath:
$xml_str = file_get_contents('salespage.xml');
$xml = new SimpleXMLElement($xml_str);
$items = $xml->xpath('/*/transfer');
print_r($items);
foreach($items as $item) {
echo $item->buyerTeamname, ': ', $item->sellerTeamname, "\n";
}
<?php
$xml = simplexml_load_file("test.xml");
echo $xml->getName() . "<br />";
foreach($xml->children() as $child)
{
echo $child->getName() . ": " . $child . "<br />";
}
?>
Is this what you want?
I'm learning how to parse XML with PHP's simple XML. My code is:
<?php
$xmlSource = "<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"no\"?> <Document xmlns=\"http://www.apple.com/itms/\" artistId=\"329313804\" browsePath=\"/36/6407\" genreId=\"6507\"> <iTunes> myApp </iTunes> </Document>";
$xml = new SimpleXMLElement($xmlSource);
$results = $xml->xpath("/Document/iTunes");
foreach ($results as $result){
echo $result.PHP_EOL;
}
print_r($result);
?>
When this runs it returns a blank screen, with no errors. If I remove all the attributes from the Document tag, it returns :
myApp SimpleXMLElement Object ( [0] => myApp )
Which is the expected result.
What am I doing wrong? Note that I don't have control over the XML source, since it's coming from Apple.
Your xml contains a default namespace. In order to get your xpath query to work you need to register this namespace, and use the namespace prefix on every xpath element you are querying (as long as these elements all fall under the same namespace, which they do in your example):
$xml = new SimpleXMLElement( $xmlSource );
// register the namespace with some prefix, in this case 'a'
$xml->registerXPathNamespace( 'a', 'http://www.apple.com/itms/' );
// then use this prefix 'a:' for every node you are querying
$results = $xml->xpath( '/a:Document/a:iTunes' );
foreach( $results as $result )
{
echo $result . PHP_EOL;
}
For the part about the default namespace, read fireeyedboy's answer. As mentionned, you need to register a namespace if you want to use XPath on nodes that are in the default namespace.
However, if you don't use xpath(), SimpleXML has its own magic that selects the default namespace automagically.
$xmlSource = "<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"no\"?> <Document xmlns=\"http://www.apple.com/itms/\" artistId=\"329313804\" browsePath=\"/36/6407\" genreId=\"6507\"> <iTunes> myApp </iTunes> </Document>";
$Document = new SimpleXMLElement($xmlSource);
foreach ($Document->iTunes as $iTunes)
{
echo $iTunes, PHP_EOL;
}
this is general example
foreach ($library->children() as $child)
{
echo $child->getName() . ":\n";
foreach ($child->attributes() as $attr)
{
echo $attr->getName() . ': ' . $attr . "\n";
}
foreach ($child->children() as $subchild)
{
echo $subchild->getName() . ': ' . $subchild . "\n";
}
echo "\n";
}

This line:
print_r($result);
is outside the foreach loop. Maybe you should try
print_r($results);
instead.
Seems if you use the wildcard (//) on xpath it will work. Also, not sure why but if you remove the namespace attribute (xmlns) from the Document element, your current code will work. Maybe because a prefix isn't defined? Anyway, following should work:
$results = $xml->xpath("//iTunes");
foreach ($results as $result){
echo $result.PHP_EOL;
}
