My XML is the following: http://api.napiarfolyam.hu/?valuta=eur
I would like to get only the 'vetel' value where the 'bank' is mnb.
My PHP is the following:
<?php
$xml=simplexml_load_file("http://api.napiarfolyam.hu/?valuta=eur") or die("Error: Cannot create object");
$vetel = (string) $xml->valuta->bank->vetel;
?>
This one should be the solution but the problem is, according to your xml file, bank mnb has no vetel. So the iterator can't see bank mnb.
$xml=simplexml_load_file("http://api.napiarfolyam.hu/?valuta=eur") or die("Error: Cannot create object");
foreach($xml->valuta->item as $item){
if($item->bank == "mnb"){
echo $item->vetel;
break;
}
}
As has already been said, there's no such node in the XML you've provided. The only <item> where <bank> is equal to "mnb" is as follows, without a <vetel> tag.
<item>
<bank>mnb</bank>
<datum>2016-09-07 11:25:32</datum>
<penznem>EUR</penznem>
<kozep>309.3500</kozep>
</item>
Using the kozep tag as an example though, you can easily use SimpleXML's xpath() method to find the matching value, e.g.
$xml = file_get_contents('http://api.napiarfolyam.hu/?valuta=eur');
$sxml = simplexml_load_string($xml);
echo (float) $sxml->xpath('/arfolyamok/deviza/item[bank = "mnb"]/kozep/text()')[0];
// 309.35

I want to change node value, sfa:TIN and save the xml in a new file. How can this be accomplished in PHP? I got examples but none used namespaces.
One way you could do this is using DOMDocument and DOMXPath and find your elements using for example an xpath expression which will find the 'TIN' elements in the sfa namespace.
/ftc:FATCA_OECD/ftc:FATCA/ftc:ReportingFI/sfa:TIN
To update the value of the first found elemement you could take the first item from the DOMNodeList which is returned by query.
$doc = new DOMDocument();
$doc->loadXML($data);
$xpath = new DOMXPath($doc);
$res = $xpath->query("/ftc:FATCA_OECD/ftc:FATCA/ftc:ReportingFI/sfa:TIN");
if ($res->length > 0) {
$res[0]->nodeValue = "test";
}
$doc->save("yourfilename.xml");
Demo
You can use the following solution, using DOMDocument::getElementsByTagNameNS:
<?php
$dom = new DOMDocument();
$dom->load('old-file.xml');
//get all TIN nodes.
$nodesTIN = $dom->getElementsByTagNameNS('urn:oecd:ties:stffatcatypes:v2', 'TIN');
//check for existing TIN node.
if (count($nodesTIN) === 1) {
//update the first TIN node.
$nodesTIN->item(0)->nodeValue = 'NEWVALUE_OF_TIN';
}
//save the file to a new one.
$dom->save('new-file.xml');
Given the XML and related PHP, below how can I get the namespaced values in the same way that I'm able to get the non-namespaced values? I've been referring to a number of other SE QAs about this, but can't seem to get it right. An help is appreciated. :)
<?xml version="1.0" encoding="UTF-8"?>
<rss version="2.0" xmlns:psg="http://b3000.example.net:3000/psg_namespace/">
<channel>
<title>Example</title>
<description>example stuff</description>
<item>
<psg:eventId>406589</psg:eventId>
<psg:duration>3482</psg:duration>
</item>
</channel>
</rss>
$xml = new SimpleXMLElement($source, null, true);
foreach($xml->channel->item as $entry){
echo $entry->title; // This works
echo $entry->description; // This works
echo $entry->item->duration // Pseudo of what I need
}
How to get Duration? My attempts with variations such as this have failed
$namespaces = $item->getNameSpaces(true);
$psg = $item->children($namespaces['psg']);
Update
While it wasn't the answer I was actually looking for, I have to accept the first answer that got me trying things leading to the actual problem - "operator error"! This DOES work....my problem was in trying to figure it out, I was debugging with echo print_r($psg, true). That was showing the result as a SimpleXmlObject, which then got me chasing how to get those properties - All I had to do was assign the property instead of echoing it.
foreach($xml->channel->item as $entry){
$psg = $item->children($ns['psg']);
$title = (string) $item->title;
$duration = (string) $psg->duration;
}
One way to achieve this is to use a combination of XPath with namespaces:
$xml = new SimpleXMLElement($source, null, true);
$xml->registerXPathNamespace('psg', 'http://b3000.example.net:3000/psg_namespace/');
foreach ($xml->xpath('//item/psg:duration') as $duration) {
echo $duration, PHP_EOL;
}
If you don't want to declare the namespace literally, you can retrieve it from the document and add it/them dynamically:
foreach ($xml->getDocNamespaces() as $key => $namespace) {
$xml->registerXPathNamespace($key, $namespace);
}
I am have two xml files.. I first get one and loop through it then I need to take an id from the first xml file and find it in the second one and echo out the results associated with that id. If I were to do this with SQL I would simply do this:
$query = (SELECT * FROM HotelSummary WHERE roomTypeCode = '$id') or die();
while($row=mysql_fetch_array($query)){
$name = $row['Name'];
}
echo $name;
How can I do this is in xml and php??
I recommend you to read the DOMDocument documentation.
It's quite heavy but also powerful (not always clear what happens, but the Internet shold always give you a solution)
You can simply walk through your first document, finding your Id and then find your DOMElement via an XPath.
<?php
$dom = new DOMDocument();
$dom->load('1.xml');
foreach ($dom->getElementsByTagName('article') as $node) {
// your conditions to find out the id
$id = $node->getAttribute('id');
}
$dom = new DOMDocument();
$dom->load('2.xml');
$xpath = new DOMXPath($dom);
$element = $xpath->query("//*[#id='".$id."']")->item(0);
// would echo "top_2" based on my example files
echo $element->getAttribute('name');
Based on following test files:
1.xml
<?xml version="1.0" encoding="UTF-8"?>
<articles>
<article id="foo_1">
<title>abc</title>
</article>
<article id="foo_2">
<title>def</title>
</article>
</articles>
2.xml
<?xml version="1.0" encoding="UTF-8"?>
<tests>
<test id="foo_1" name="top_1">
</test>
<test id="foo_2" name="top_2">
</test>
</tests>
Use SimpleXML to create an object representation of the file. You can then loop through the elements of the Simple XML object.
Depending on the format of the XML file:
Assuming it is:
<xml>
<roomTypeCode>
<stuff>stuff</stuff>
<name>Skunkman</name>
</roomTypeCode>
<roomTypeCode>
<stuff>other stuff</stuff>
<name>Someone Else</name>
</roomTypeCode>
</xml>
It would be something like this:
$xml = simplexml_load_file('xmlfile.xml');
for($i = 0; $i < count($xml->roomTypeCode); $i++)
{
if($xml->roomTypeCode[$i]->stuff == "stuff")
{
$name = $xml->roomTypeCode[$i]->name;
}
}
That connects to the XML file, finds how many roomTypeCode entries there are, searches for the value of "stuff" within and when it matches it correctly, you can access anything having to do with that XML entry.
Hello I know there is many questions here about those three topics combined together to update XML entries, but it seems everyone is very specific to a given problem.
I have been spending some time trying to understand XPath and its way, but I still can't get what I need to do.
Here we go
I have this XML file
<?xml version="1.0" encoding="UTF-8"?>
<storagehouse xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="schema.xsd">
<item id="c7278e33ef0f4aff88da10dfeeaaae7a">
<name>HDMI Cable 3m</name>
<weight>0.5</weight>
<category>Cables</category>
<location>B3</location>
</item>
<item id="df799fb47bc1e13f3e1c8b04ebd16a96">
<name>Dell U2410</name>
<weight>2.5</weight>
<category>Monitors</category>
<location>C2</location>
</item>
</storagehouse>
What I would like to do is to update/edit any of the nodes above when I need to. I will do a Html form for that.
But my biggest conserne is how do I find and update a the desired node and update it?
Here I have some of what I am trying to do
<?php
function fnDOMEditElementCond()
{
$dom = new DOMDocument();
$dom->load('storage.xml');
$library = $dom->documentElement;
$xpath = new DOMXPath($dom);
// I kind of understand this one here
$result = $xpath->query('/storagehouse/item[1]/name');
//This one not so much
$result->item(0)->nodeValue .= ' Series';
// This will remove the CDATA property of the element.
//To retain it, delete this element (see delete eg) & recreate it with CDATA (see create xml eg).
//2nd Way
//$result = $xpath->query('/library/book[author="J.R.R.Tolkein"]');
// $result->item(0)->getElementsByTagName('title')->item(0)->nodeValue .= ' Series';
header("Content-type: text/xml");
echo $dom->saveXML();
}
?>
Could someone maybe give me an examples with attributes and so on, so one a user decides to update a desired node, I could find that node with XPath and then update it?
The following example is making use of simplexml which is a close friend of DOMDocument. The xpath shown is the same regardless which method you use, and I use simplexml here to keep the code low. I'll show a more advanced DOMDocument example later on.
So about the xpath: How to find the node and update it. First of all how to find the node:
The node has the element/tagname item. You are looking for it inside the storagehouse element, which is the root element of your XML document. All item elements in your document are expressed like this in xpath:
/storagehouse/item
From the root, first storagehouse, then item. Divided with /. You already know that, so the interesting part is how to only take those item elements that have the specific ID. For that the predicate is used and added at the end:
/storagehouse/item[#id="id"]
This will return all item elements again, but this time only those which have the attribute id with the value id (string). For example in your case with the following XML:
$xml = <<<XML
<?xml version="1.0" encoding="UTF-8"?>
<storagehouse xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="schema.xsd">
<item id="c7278e33ef0f4aff88da10dfeeaaae7a">
<name>HDMI Cable 3m</name>
<weight>0.5</weight>
<category>Cables</category>
<location>B3</location>
</item>
<item id="df799fb47bc1e13f3e1c8b04ebd16a96">
<name>Dell U2410</name>
<weight>2.5</weight>
<category>Monitors</category>
<location>C2</location>
</item>
</storagehouse>
XML;
that xpath:
/storagehouse/item[#id="df799fb47bc1e13f3e1c8b04ebd16a96"]
will return the computer monitor (because such an item with that id exists). If there would be multiple items with the same id value, multiple would be returned. If there were none, none would be returned. So let's wrap that into a code-example:
$simplexml = simplexml_load_string($xml);
$result = $simplexml->xpath(sprintf('/storagehouse/item[#id="%s"]', $id));
if (!$result || count($result) !== 1) {
throw new Exception(sprintf('Item with id "%s" does not exists or is not unique.', $id));
}
list($item) = $result;
In this example, $titem is the SimpleXMLElement object of that computer monitor xml element name item.
So now for the changes, which are extremely easy with SimpleXML in your case:
$item->category = 'LCD Monitor';
And to finally see the result:
echo $simplexml->asXML();
Yes that's all with SimpleXML in your case.
If you want to do this with DOMDocument, it works quite similar. However, for updating an element's value, you need to access the child element of that item as well. Let's see the following example which first of all fetches the item as well. If you compare with the SimpleXML example above, you can see that things not really differ:
$doc = new DOMDocument();
$doc->loadXML($xml);
$xpath = new DOMXPath($doc);
$result = $xpath->query(sprintf('/storagehouse/item[#id="%s"]', $id));
if (!$result || $result->length !== 1) {
throw new Exception(sprintf('Item with id "%s" does not exists or is not unique.', $id));
}
$item = $result->item(0);
Again, $item contains the item XML element of the computer monitor. But this time as a DOMElement. To modify the category element in there (or more precisely it's nodeValue), that children needs to be obtained first. You can do this again with xpath, but this time with an expression relative to the $item element:
./category
Assuming that there always is a category child-element in the item element, this could be written as such:
$category = $xpath->query('./category', $item)->item(0);
$category does now contain the first category child element of $item. What's left is updating the value of it:
$category->nodeValue = "LCD Monitor";
And to finally see the result:
echo $doc->saveXML();
And that's it. Whether you choose SimpleXML or DOMDocument, that depends on your needs. You can even switch between both. You probably might want to map and check for changes:
$repository = new Repository($xml);
$item = $repository->getItemByID($id);
$item->category = 'LCD Monitor';
$repository->saveChanges();
echo $repository->getXML();
Naturally this requires more code, which is too much for this answer.
my xml file:
<temporary>
<users>
<temp>
<id>1</id>
<title> Undercover</title>
<author>Wiwit</author>
</temp>
<nissi>
<confirm>3977678bce8515e8cdbfa64850904ad1</confirm>
<firstname>hi</firstname>
<lastname>hhey</lastname>
<day>1</day>
</nissi>
</users>
</temporary>
my php:
<?php
$user="nissi";
$xml = simplexml_load_file("temporary.xml")
or die("Error: Cannot create object");
unset($xml->temporary->users->$user);
?>
Why is this not working.
The unset is not working.The node ins'nt getting deleted.
It works like this :
$user="nissi";
$xml = simplexml_load_file("temporary.xml")
or die("Error: Cannot create object");
unset($xml->users->$user);
echo $xml->asXML();
You mustn't take the root of your xml in the "request" temporary here.

You cannot do it with SimpleXML alone, you have to use DOMElement conversion as explained here:
