I am creating xml file as below, can anybody help how to get that using php?
xml file:
<products>
<product id="123" />
</products>
Php file:
i am using following code but not getting result as above
$xml = new DomDocument('1.0', 'utf-8');
$xml->formatOutput = true;
$products= $xml->createElement('products');
$product = $xml->createElement('product');
$id = $xml->createElement('id');
$xml->appendChild($products);
$products->appendChild($product);
$product->appendChild($id);
$id->nodeValue = 123;
$xml->save("data.xml");
retrieving xml data:
$xml = new DomDocument();
$xmlFile = "data.xml";
$xml= DOMDocument::load($xmlFile);
$product = $xml->getElementsByTagName("product");
foreach($product as $node)
{
$address = $node->getElementsByAttributeName("address");
$address = $address->item(0)->nodeValue;
echo"$address";
}
You are not getting the results you want because you're adding id as a tag rather than an attribute. I just refactored your code a little and made id an attribute. I tested the code below and it produces your desired result.
<?php
$xml = new DomDocument('1.0', 'utf-8');
$xml->formatOutput = true;
$products= $xml->createElement('products');
$product = $xml->createElement('product');
$xml->appendChild($products);
$products->appendChild($product);
$product->appendChild(new DomAttr('id', '123'));
$xml->save("data.xml");
?>
If id is to be an attribute, then you need to use the DOMElement::setAttribute() method. I think this will work - according to the documentation, if an attribute doesn't already exist it will be created.
$product->setAttribute("id", "123");
Then loas the $product->appendChild( $id );

I am creating an XML file in PHP like this...
$myXML = new DOMDocument();
$myXML ->formatOutput = true;
$data = $myXML ->createElement('data');
$data->nodeValue = 'mydata';
$final->appendChild($data);
$myXML ->save('/mypath/myfile.xml');
This works, but how can I convert this to use saveXML() instead? I have tried like this but I get nothing
$myXML->saveXML();
Where am I going wrong?
I see two things:
$final is not declared. Change it.
In case saveXML() is called, the output has to be assigned to a variable or printed
Here goes the working code:
<?php
$myXML = new DOMDocument();
$myXML ->formatOutput = true;
$data = $myXML ->createElement('data');
$data->nodeValue = 'mydata';
$myXML->appendChild($data);
echo $myXML ->saveXML();
?>
Output:
<?xml version="1.0"?>
<data>mydata</data>
I have a question: I am trying to create a XML file using DomDocument and I would like to have this output:
<?xml version="1.0" encoding="UTF-8"?>
<winstrom version="1.0">
<main_tag>
<child_tag>example</child_tag>
</main_tag>
<winstrom>
The problem is with the second row - if I write it as below then the output is "Invalid Character Error". I guess it is not allowed to have space characters there... However I need it like this, so what are the options?
$dom = new DomDocument('1.0', 'UTF-8');
$root = $dom->createElement('winstrom version=1.0');
$dom->appendChild($root);
$item = $dom->createElement('hlavni_tag');
$root2->appendChild($item);
$text = $dom->createTextNode('example');
$item->appendChild($text);
$dom->formatOutput = true;
echo $dom->saveXML();
There seems to be a misunderstanding of what an XML element is and how it differs from attributes.
Try this code:
<?php
$dom = new DomDocument('1.0', 'UTF-8');
$root = $dom->createElement('winstrom');
$root->setAttribute("version","1.0");
$dom->appendChild($root);
$root2 = $dom->createElement("main_tag"); //You forgot this part
$root->appendChild($root2);
$item = $dom->createElement('hlavni_tag'); //Should it be "child_tag"?
$root2->appendChild($item);
$text = $dom->createTextNode('example');
$item->appendChild($text);
$dom->formatOutput = true;
echo $dom->saveXML();
I want this code to replace in the "platform" tag with something like "newData"
$xml = new DOMDocument();
$xml->load('myhappyfarmsave.xml');
$xpath = new DOMXPath($xml);
$elements = $xpath->query('/myhappyfarmsave/platform');
$domElement = $elements->item(0);
var_dump($domElement->textContent);
$domElement->textContent = "newData";
$xml->save('myhappyfarmsavenew.xml');
I don't know what's wrong with my code. thanks for your help
<?xml version="1.0" encoding="UTF-8"?>
<myhappyfarmsave version="3">
<platform>Bazaar</platform>
<timestamp>1356876534</timestamp>
<lastlogtime>1356823542</lastlogtime>
</myhappyfarmsave>
Well, $node->textContent is a readonly value, so you cannot modify it.
Try playing with $node->nodeValue instead:
$domElement = $elements->item(0);
$domElement->nodeValue = "newData";
$xml->save('myhappyfarmsavenew.xml');
I have the following code in my PHP script:
$str = '<item></item>';
$xml = new DOMDocument('1.0', 'UTF-8');
$xml->formatOutput = true;
$xml->load('file.xml');
$items = $addon->getElementsByTagName('items')->item(0);
$items->nodeValue = $str;
$xml->save('file.xml');
In the saved file.xml I see the following:
<item><\item>
How can I save it in the XML file without encoding HTML entities?
Use a DOMDocumentFragment:
<?php
$doc = new DOMDocument();
$doc->load('file.xml'); // '<doc><items/></doc>'
$item = $doc->createDocumentFragment();
$item->appendXML('<item id="1">item</item>');
$doc->getElementsByTagName('items')->item(0)->appendChild($item);
$doc->save('file.xml');
If you're appending to the root element, use $doc->documentElement->appendChild($item); instead of getElementsByTagName.
My question is best phrase as:
Remove a child with a specific attribute, in SimpleXML for PHP
except I'm not using simpleXML.
I'm new to XML for PHP so I may not be doing the best way
I have a xml created using the $dom->save($xml) for each individual user. (not placing all in one xml due to undisclosed reasons)
It gives me that xml declaration <?xml version="1.0"?> (no idea how to make it to others, but that's not the point, hopefully)
<?xml version="1.0"?>
<details>
<person>name</person>
<data1>some data</data1>
<data2>some data</data2>
<data3>some data</data3>
<category id="0">
<categoryName>Cat 1</categoryName>
<categorydata1>some data</categorydata1>
</category>
<category id="1">
<categoryName>Cat 2</categoryName>
<categorydata1>some data</categorydata1>
<categorydata2>some data</categorydata2>
<categorydata3>some data</categorydata3>
<categorydata4>some data</categorydata4>
</category>
</details>
And I want to remove a category that has a specific attribute named id with the DOM class in php when i run a function activated from using a remove button.
the following is the debug of the function im trying to get to work. Can i know what I'm doing wrong?
function CatRemove($myXML){
$xmlDoc = new DOMDocument();
$xmlDoc->load( $myXML );
$categoryArray = array();
$main = $xmlDoc->getElementsByTagName( "details" )->item(0);
$mainElement = $xmlDoc->getElementsByTagName( "details" );
foreach($mainElement as $details){
$currentCategory = $details->getElementsByTagName( "category" );
foreach($currentCategory as $category){
$categoryID = $category->getAttribute('id');
array_push($categoryArray, $categoryID);
if($categoryID == $_POST['categorytoremoveValue']) {
return $categoryArray;
}
}
}
$xmlDoc->save( $myXML );
}
Well the above prints me an array of [0]->0 all the time when i slot the return outside the if.
is there a better way? I've tried using getElementbyId as well but I've no idea how to work that.
I would prefer not to use an attribute though if that would make things easier.
Ok, let’s try this complete example of use:
function CatRemove($myXML, $id) {
$xmlDoc = new DOMDocument();
$xmlDoc->load($myXML);
$xpath = new DOMXpath($xmlDoc);
$nodeList = $xpath->query('//category[#id="'.(int)$id.'"]');
if ($nodeList->length) {
$node = $nodeList->item(0);
$node->parentNode->removeChild($node);
}
$xmlDoc->save($myXML);
}
// test data
$xml = <<<XML
<?xml version="1.0"?>
<details>
<person>name</person>
<data1>some data</data1>
<data2>some data</data2>
<data3>some data</data3>
<category id="0">
<categoryName>Cat 1</categoryName>
<categorydata1>some data</categorydata1>
</category>
<category id="1">
<categoryName>Cat 2</categoryName>
<categorydata1>some data</categorydata1>
<categorydata2>some data</categorydata2>
<categorydata3>some data</categorydata3>
<categorydata4>some data</categorydata4>
</category>
</details>
XML;
// write test data into file
file_put_contents('untitled.xml', $xml);
// remove category node with the id=1
CatRemove('untitled.xml', 1);
// dump file content
echo '<pre>', htmlspecialchars(file_get_contents('untitled.xml')), '</pre>';
So you want to remove the category node with a specific id?
$node = $xmlDoc->getElementById("12345");
if ($node) {
$node->parentNode->removeChild($node);
}
You could also use XPath to get the node, for example:
$xpath = new DOMXpath($xmlDoc);
$nodeList = $xpath->query('//category[#id="12345"]');
if ($nodeList->length) {
$node = $nodeList->item(0);
$node->parentNode->removeChild($node);
}
I haven’t tested it but it should work.
Can you try with this modified version:
function CatRemove($myXML, $id){
$doc = new DOMDocument();
$doc->loadXML($myXML);
$xpath = new DOMXpath($doc);
$nodeList = $xpath->query("//category[#id='$id']");
foreach ($nodeList as $element) {
$element->parentNode->removeChild($element);
}
echo htmlentities($doc->saveXML());
}
It's working for me. Just adapt it to your needs. It's not intended to use as-is, but just a proof of concept.
You also have to remove the xml declaration from the string.
the above funciton modified to remove an email from a mailing list
function CatRemove($myXML, $id) {
$xmlDoc = new DOMDocument();
$xmlDoc->load($myXML);
$xpath = new DOMXpath($xmlDoc);
$nodeList = $xpath->query('//subscriber[#email="'.$id.'"]');
if ($nodeList->length) {
$node = $nodeList->item(0);
$node->parentNode->removeChild($node);
}
$xmlDoc->save($myXML);
}
$xml = 'list.xml';
$to = $_POST['email'];//user already submitted they email using a form
CatRemove($xml,$to);
