adding a new node in XML file via PHP
24,656
Solution 1
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");
Solution 2
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');

I just wanted to ask a question .. how can i 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 "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');
?>

MatRt over 11 yearsYou have to create a new element
$newSubTopic = $xmldoc->createElement('subtopic');
, then create a new text node$subTopicContent = $xmldoc->createTextNode('geology');
, and finally append the textnode in the new topic element, and then append te new topic element to your desire node. -
