Say, I have the following php code:
<?php
$resultXML = "<root><book></book></root>";
$resultXML = new SimpleXMLElement($resultXML);
?>
How can I insert the following XML: <car><bmw></bmw></car> such that I get <root><car><bmw></bmw></car><book></book></root>
Basically, I want to generic solution to insert an element (with its children, grandchildren etc) in an existing XML. Any help?
Try this
$resultXML = new SimpleXMLElement('<root><book></book></root>');
$car=$resultXML->addChild('car');
$car->addChild('bmw');
$resultXML->asXML('path/to/save/abc.xml');

I know how to extract the data from between two tags or elements but I do not know how to extract the data from within the element itself for example (see this section Tax="0.0" EHF="0.0" Freight="0.0" Handling="0.0" SubTotal="0.72"). Any help would be most appreciated.
<INVTOTAL Tax="0.0" EHF="0.0" Freight="0.0" Handling="0.0" SubTotal="0.72">0.72</INVTOTAL>
There are a few ways to do it. For example, using xpath, something like
$invoice= '
<root><INVTOTAL Tax="10.0" EHF="0.0" Freight="0.0" Handling="0.0" SubTotal="0.72">0.72</INVTOTAL></root>';
$XMLDoc = new DOMDocument();
$XMLDoc->loadXML($invoice);
$xpath = new DOMXPath($XMLDoc);
$tax = $xpath->query("//INVTOTAL/#Tax");
echo($tax[0]->nodeValue);
Output:
10.0
The xml file to parse https://webassos.com/uploads/results/ffnex_performances_54059.xml
<?php
$file = 'https://webassos.com/uploads/results/ffnex_performances_54059.xml';
$xml = simplexml_load_file($file);
print_r($xml);
?>
Return a well formated array with XML elements and attributes
<?php
$meeting = $xml->MEET;
print_r($meeting);
?>
Return an empty object.
Same result with a DOM document and trying to get element MEET by tagName.
Why this method that I usually use does not work in this case, please?
Please check your structure You have a child node meets and there you find meet
var_dump($xml->MEETS->MEET);
I just wanted to ask how I can insert a new node in an XML using PHP. my XML file (questions.xml) is given below
<?xml version="1.0" encoding="UTF-8"?>
<Quiz>
<topic text="Preparation for Exam">
<subtopic text="Science" />
<subtopic text="Maths" />
<subtopic text="english" />
</topic>
</Quiz>
I want to add a new "subtopic" with the "text" attribute, that is "geography". How can I do this using PHP? Thanks in advance though.
well my code is
<?php
$xmldoc = new DOMDocument();
$xmldoc->load('questions.xml');
$root = $xmldoc->firstChild;
$newElement = $xmldoc->createElement('subtopic');
$root->appendChild($newElement);
// $newText = $xmldoc->createTextNode('geology');
// $newElement->appendChild($newText);
$xmldoc->save('questions.xml');
?>
I'd use SimpleXML for this. It would look somehow like this:
// Open and parse the XML file
$xml = simplexml_load_file("questions.xml");
// Create a child in the first topic node
$child = $xml->topic[0]->addChild("subtopic");
// Add the text attribute
$child->addAttribute("text", "geography");
You can either display the new XML code with echo or store it in a file.
// Display the new XML code
echo $xml->asXML();
// Store new XML code in questions.xml
$xml->asXML("questions.xml");
The best and safe way is to load your XML document into a PHP DOMDocument object, and then go to your desired node, add a child, and finally save the new version of the XML into a file.
Take a look at the documentation : DOMDocument
Example of code:
// open and load a XML file
$dom = new DomDocument();
$dom->load('your_file.xml');
// Apply some modification
$specificNode = $dom->getElementsByTagName('node_to_catch');
$newSubTopic = $xmldoc->createElement('subtopic');
$newSubTopicText = $xmldoc->createTextNode('geography');
$newSubTopic->appendChild($newSubTopicText);
$specificNode->appendChild($newSubTopic);
// Save the new version of the file
$dom->save('your_file_v2.xml');
You can use PHP's Simple XML. You have to read the file content, add the node with Simple XML and write the content back.
I am trying to write a code where it will find a specific element in my XML file and then change the value of the text node. The XML file has different namespaces. Till now, I have managed to register the namespaces and also echo the text node of the element, which I want to change.
<?php
$xml = simplexml_load_file('getobs.xml');
$xml->registerXPathNamespace('g','http://www.opengis.net/gml');
$result = $xml->xpath('//g:beginPosition');
foreach ($result as $title) {
echo $title . "\n";
}
?>
My question is: How can I change the value of this element using SimpleXML? I tried to use the nodeValue command but I am not able to make it work.
This is a part of the XML:
<sos:GetObservation xmlns:sos="http://www.opengis.net/sos/1.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" service="SOS" version="1.0.0" srsName="urn:ogc:def:crs:EPSG:4326">
<sos:offering>urn:gfz:cawa:def:offering:meteorology</sos:offering>
<sos:eventTime>
<ogc:TM_During xmlns:ogc="http://www.opengis.net/ogc" xsi:type="ogc:BinaryTemporalOpType">
<ogc:PropertyName>urn:ogc:data:time:iso8601</ogc:PropertyName>
<gml:TimePeriod xmlns:gml="http://www.opengis.net/gml">
<gml:beginPosition>2011-02-10T01:10:00.000</gml:beginPosition>
Thanks

In the end I managed to do it by using the PHP XML DOM.
Here is the code that I used in order to change the text node of a specific element:
<?php
// create new DOM document and load the data
$dom = new DOMDocument;
$dom->load('getobs.xml');
//var_dump($dom);
// Create new xpath and register the namespace
$xpath = new DOMXPath($dom);
$xpath->registerNamespace('g','http://www.opengis.net/gml');
// query the result amd change the value to the new date
$result = $xpath->query("//g:beginPosition");
$result->item(0)->nodeValue = 'sds';
// save the values in a new xml
file_put_contents('test.xml',$dom->saveXML());
?>
Not wanting to switch from the code I've already made for SimpleXML, I found this solution:
http://www.dotdragnet.com/forum/index.php?topic=3979.0
Specificially:
$numvotes = $xml->xpath('/gallery/image[path="'.$_GET["image"].'"]/numvotes');
...
$numvotes[0][0] = $votes;
Hope this helps!
I have source XML here: http://www.grilykrby.cz/rss/pf-heureka.xml. I want to use this xml feed and create another modified on my own server. I would like to change every node CATEGORYTEXT which contains word Prislusenstvi. I just tried something but I got only the listing of all categories without changing XML :-(
Here is the example of my code. The row $kategorie="nejaka kategorie"; doesn't work.
<?php
$file = "http://www.grilykrby.cz/rss/pf-heureka.xml";
$xml=simplexml_load_file($file);
foreach ($xml->xpath('//SHOPITEM/CATEGORYTEXT') as $kategorie) {
echo $kategorie."<br />";
$kategorie="nejaka kategorie";
}
file_put_contents('test.xml', $xml->asXML());
?>
$kategorie is just a temp variable used in the loop which contains a copy of the data returned by xpath query. You would need to actually set the value directly in the $xml object.
I would personally also consider doing a str_replace or preg_replace within the XML content itself before parsing it into a simpleXML object.
Final Accepted Answer
<?php
$xml = simplexml_load_file('http://www.grilykrby.cz/rss/pf-heureka.xml');
$i=0;
foreach($xml -> SHOPITEM as $polozka) {
if ($polozka -> CATEGORYTEXT == "Příslušenství") $xml -> SHOPITEM[$i] -> CATEGORYTEXT = "Some other text";
$i++;
}
?>
