I want to print values inside elemnts of xml file but i have a problem.
This xml sitemap:
<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl" href="/sitemap.xsl"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
<url><loc>https://www.example.com/1</loc></url>
<url><loc>https://www.example.com/2</loc></url>
</urlset>
and this is my code:
$url_sitemap = "file.xml";
$xml_sitemap = simplexml_load_file($url_sitemap);
foreach($xml_sitemap-> urlset -> url as $url){
$link= $url->loc;
print_r($link);
}
but i have this error: Warning: Invalid argument supplied for foreach() in
If you print_r($xml_sitemap); you'll see that it doesn't contain the urlset:
SimpleXMLElement Object
(
[url] => Array
(
[0] => SimpleXMLElement Object
(
[loc] => https://www.example.com/1
)
[1] => SimpleXMLElement Object
(
[loc] => https://www.example.com/2
)
)
)
You can then use
foreach ($xml_sitemap as $url) {
echo $url->loc;
}
to output all locs

This should be am easy task, but I just didn't get it working:
In the below code snippet, I would like to select the <WebFilterCategory> node which has a <Name> child that has a value of "Categoryname2":
<?php
$xmlstring = <<<XML
<?xml version="1.0" encoding="UTF-8"?>
<Request>
<Login>
<UserName>admin</UserName>
<Password>admin</Password>
</Login>
<Set Operation="get">
<WebFilterCategory transactionid="">
<Name>Categoryname1</Name>
<Classification>Objectionable</Classification>
<DomainList>
<Domain>example1.com</Domain>
<Domain>example2.com</Domain>
</DomainList>
</WebFilterCategory>
<WebFilterCategory transactionid="">
<Name>Categoryname2</Name>
<Classification>Objectionable</Classification>
<DomainList>
<Domain>example1.org</Domain>
<Domain>example2.org</Domain>
</DomainList>
</WebFilterCategory>
</Set>
</Request>
XML;
$xml = simplexml_load_string( $xmlstring ) or die("Error: Cannot create object");
foreach ($xml->query('//WebFilterCategory/Name[contains(., "Categoryname2")]') as $category) {
print_r($xmlstring);
}
?>
Probably, there's a much leaner query to get the desired result, too.
The method you are looking for is not query but xpath
Then you could update the path to match the WebFilterCategory where the Name contains Categoryname2
//WebFilterCategory[Name[contains(., "Categoryname2")]]'
Updated code
$xml = simplexml_load_string( $xmlstring ) or die("Error: Cannot create object");
foreach ($xml->xpath('//WebFilterCategory[Name[contains(., "Categoryname2")]]') as $category) {
print_r($category);
}
Output
SimpleXMLElement Object
(
[#attributes] => Array
(
[transactionid] =>
)
[Name] => Categoryname2
[Classification] => Objectionable
[DomainList] => SimpleXMLElement Object
(
[Domain] => Array
(
[0] => example3.org
[1] => example2.org
)
)
)

I have a large XML with the following:
<?xml version="1.0" encoding="UTF-8"?>
<valasz xmlns="" verzio="1.0">
<arak>
<ar>
<cikkid>439902</cikkid>
<cikkszam>DVDV-16Z10</cikkszam>
<listaar>1225,0000000</listaar>
<ar>1157,6200000</ar>
<akcios_ar>1157,6200000</akcios_ar>
<devizanem>HUF</devizanem>
</ar>
<ar>
..
<ar>1157,6200000</ar>
...
</ar>
</arak>
What i want is to remove arak->ar->ar child because its causing in the import it looks like duplicates, and slowing down the process.
I have tried the following:
$node = readfile($arlista[0]);
$nodes = simplexml_load_string($node);
$arnode = $nodes->xpath("/valasz/arak/ar/ar");
foreach ($arnode as &$ar){
$nodes->removeChild($ar);
}
echo $nodes;
And this only returns me the original xml, without removing the arak->ar->ar child nodes.
What am i doing wrong?
There is no such thing as ::removeChild() in SimpleXML.
What you want do do in your foreach loop is this:
foreach ($arnode as $ar){
unset($ar->{0});
}
Please note: The posted XML is not valid but I am sure that is just some kind of copy&paste flaw
Complete code:
$xml = '<?xml version="1.0" encoding="UTF-8"?>
<valasz xmlns="" verzio="1.0">
<arak>
<ar>
<cikkid>439902</cikkid>
<cikkszam>DVDV-16Z10</cikkszam>
<listaar>1225,0000000</listaar>
<ar>1157,6200000</ar>
<akcios_ar>1157,6200000</akcios_ar>
<devizanem>HUF</devizanem>
</ar>
<ar>
<ar>1157,6200000</ar>
</ar>
</arak>
</valasz>';
$nodes = simplexml_load_string($xml);
$arnode = $nodes->xpath("/valasz/arak/ar/ar");
foreach ($arnode as $ar){
unset($ar->{0});
}
print_r($nodes);
Returns this
SimpleXMLElement Object
(
[#attributes] => Array
(
[verzio] => 1.0
)
[arak] => SimpleXMLElement Object
(
[ar] => Array
(
[0] => SimpleXMLElement Object
(
[cikkid] => 439902
[cikkszam] => DVDV-16Z10
[listaar] => 1225,0000000
[akcios_ar] => 1157,6200000
[devizanem] => HUF
)
[1] => SimpleXMLElement Object

How do you parse and process HTML/XML in PHP?
(31 answers)
Closed 7 years ago.
I have php code connecting to an API:
require(dirname(__FILE__) . '/MadMimi.class.php');
$mailer = new MadMimi('XXX.org', '000');
$lists = $mailer->Lists();
var_dump($lists);
foreach ($lists as $list) {
echo $list['name']; }
var_dump shows a XML doc in the form:
`string '<?xml version="1.0" encoding="UTF-8"?>
<lists>
<list id="8" name="#1" subscriber_count="210" display_name="Display name"/>
<list id="9" name="#2" subscriber_count="2242" display_name="Display name"/>`
...(length=2726)
but it only shows the first few lines. How do I make it show all the values?
Also I'm trying to print specific values using the foreach loop but it isn't working and I'm getting the error: Invalid argument supplied for foreach()
If foreach doesn't work how else can I obtain values from the XML doc?
If I do
$xml=simplexml_load_string($lists) or die("Error: Cannot create object");
print_r($xml);
I get:
SimpleXMLElement Object ( [list] => Array ( [0] => SimpleXMLElement Object ( [#attributes] => Array ( [id] => 8 [name] => #1 [subscriber_count] => 210 [display_name] => Display name ) ) [1] => SimpleXMLElement Object ( [#attributes] => Array ( [id] => 9 [name] => #2 [subscriber_count] => 2242 [display_name] => Display name ) )
how do I write a foreach loop for this?
It will help you.
$lists = '<?xml version="1.0" encoding="UTF-8"?>
<lists>
<list id="8" name="#1" subscriber_count="210" display_name="Display name"/>
<list id="9" name="#2" subscriber_count="2242" display_name="Display name"/>
</lists>';
$xml = simplexml_load_string($lists) or die("Error: Cannot create object");
foreach ($xml->children() as $child) {
// List all the tags
echo '<pre>';print_r($child);echo '</pre>';
foreach($child->attributes() as $a => $b) {
// list all the attributes
echo $a,'="',$b,"\"\n";
}
}
I'm not sure how your XML looks like but you can read XML in php:
$file = "path to XML";
$xml=simplexml_load_file($file) or die("Error: Cannot create object");
print_r($xml);
This will return a simple XML object.
If your XML contains sub-children then you can use a foreach loop to traverse it.
i have xml/gpx file:
<?xml version="1.0" encoding="utf-8"?>
<gpx xsi:schemaLocation="http://www.topografix.com/GPX/1/1">
<metadata>
....
</metadata>
<trk>
<trkseg>
<trkpt lat="50.04551333333333" lon="14.434101666666667">
<ele>282</ele>
<time>2014-06-30T20:56:03.92</time>
<extensions>
<gpxtpx:TrackPointExtension>
<gpxtpx:hr>100</gpxtpx:hr>
</gpxtpx:TrackPointExtension>
</extensions>
</trkpt>
...
</gpx>
Load:
$xml=simplexml_load_file($gpx_file);
parse witch
foreach($xml->trk->trkseg->trkpt as $point){}
Thats fine. But i cant get content of /extension//extension/
print_r($point) is
SimpleXMLElement Object
(
[#attributes] => Array
(
[lat] => 50.04527
[lon] => 14.433993333333333
)
[ele] => 280.5
[time] => 2014-06-30T20:57:21.71
[extensions] => SimpleXMLElement Object
(
)
)
and i cannot get SimpleXMLElement Object.
Print_r($point->extension is:
SimpleXMLElement Object
(
)
I try Converting a SimpleXML Object to an Array and other similiar way, but i have failed - output is empty array.
Any idea/way to get into string/array ?
Sample gpx is on www.vovcinec.net/gpx/e.gpx (~700kB)
You can't get them directly since they are in namespaces, you need to use getNamespaces() method first. Consider this example:
$xml = simplexml_load_file('e.gpx');
foreach($xml->trk->trkseg->trkpt as $trkpt) {
$namespaces = $trkpt->getNamespaces(true);
$gpxtpx = $trkpt->extensions->children($namespaces['gpxtpx']);
$hr = (string) $gpxtpx->TrackPointExtension->hr;
echo '<pre>';
print_r($hr);
echo '</pre>';
}
I hope you help following code
foreach($gpx->trk->trkseg->children() as $trkpts) {
echo (string)$trkpts->extensions->children('gpxtpx',true)->TrackPointExtension->hr;
}
no need to use getNamespaces() method
I have a some problem with get value from xml.
XML look like
<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl" href="http://crd.gov.pl/xml/schematy/UPO/2008/05/09/UPO.xsl"?>
<pos:Document xmlns:pos="SOMEURL"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<pos:DescribeDoc/>
<pos:UPD>
<pos:IdDoc>procotol-UPD2198338</pos:IdDoc>
<pos:IdCases>221872</pos:IdCases>
<pos:additionalInfo TypeInfo="Source">Some string</pos:additionalInfo>
</pos:UPD>
...
I general try to get to pos:IdCases.
I try this code:
$domContent = new SimpleXMLElement(((string) $content), LIBXML_COMPACT);
$test = $domContent->xpath('/pos:Document/pos:UPD/*');
foreach($test as $node){
print_r($node)
}
I get a some object such as
SimpleXMLElement Object
(
[0] => procotol-UPD2198338
)
SimpleXMLElement Object
(
[0] => 221872
)
SimpleXMLElement Object
(
[#attributes] => Array
(
[TypeInfo] => Source
)
[0] => Some string
)
But I must get to pos:IdCases. I can't use index [1] because order can change.
My question is:
How can I get to value in node: pos:IdCases
I can't add id or another info to node because this xml was signed (XADES).
Can you give me some advice? Thanks for help
Simply change the XPath to match the <Pos:IdCases/> node:
$test = $domContent->xpath('/pos:Document/pos:UPD/pos:IdCases');
