I am trying to generate a Google Merchant RSS Feed, using PHP's SimpleXML and DOMDocument.
The actual generating code goes like that:
$dom = new DOMDocument('1.0', 'utf-8');
$dom->formatOutput = true;
$pRSS = $dom->createElement('rss');
$pRSS->setAttribute('version', '2.0');
$pRSS->setAttribute('xmlns:g', 'http://base.google.com/ns/1.0');
$dom->appendChild($pRSS);
$domnode = dom_import_simplexml($xml);
$domnode = $dom->importNode($domnode, true);
$domnode = $dom->appendChild($domnode);
$dom->save('googleproductfeed.xml');
($xml has all the data, but it's not relevant to my problem)
It all gets generated fine, but there is an XML error here:
<?xml version="1.0" encoding="utf-8"?>
<rss version="2" xmlns:g="http://base.google.com/ns/1.0"/>
According to Google Merchant, Google Chrome and validome.org, there is an error in the second line.
More precisely, Validome says that it should not end with />, but just >.
The problem is I have no control over that. That part was generated by:
$pRSS = $dom->createElement('rss');
$pRSS->setAttribute('version', '2.0');
$pRSS->setAttribute('xmlns:g', 'http://base.google.com/ns/1.0');
Shouldn't <rss> be the parent element to all the contents of the feed?
It would mean that you need to append the imported XML to $pRSS, not the parent document.
$domnode = dom_import_simplexml($xml);
$domnode = $dom->importNode($domnode, true);
$domnode = $pRSS->appendChild($domnode); // Change here
Not entirely sure right now whether this won't create an extra, unnecessary node under <rss>, but it's the right direction in any case.
You should add other nodes as children to $pRSS

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');
I am trying to export xml with CDATA tags. I use the following code:
$xml_product = $xml_products->addChild('product');
$xml_product->addChild('mychild', htmlentities("<![CDATA[" . $mytext . "]]>"));
The problem is that I get CDATA tags < and > escaped with < and > like following:
<mychild><![CDATA[My some long long long text]]></mychild>
but I need:
<mychild><![CDATA[My some long long long text]]></mychild>
If I use htmlentities() I get lots of errors like tag raquo is not defined etc... though there are no any such tags in my text. Probably htmlentities() tries to parse my text inside CDATA and convert it, but I dont want it either.
Any ideas how to fix that? Thank you.
UPD_1 My function which saves xml to file:
public static function saveFormattedXmlFile($simpleXMLElement, $output_file) {
$dom = new DOMDocument('1.0', 'UTF-8');
$dom->preserveWhiteSpace = false;
$dom->formatOutput = true;
$dom->loadXML(urldecode($simpleXMLElement->asXML()));
$dom->save($output_file);
}
A short example of how to add a CData section, note the way it skips into using DOMDocument to add the CData section in. The code builds up a <product> element, $xml_product has a new element <mychild> created in it. This newNode is then imported into a DOMElement using dom_import_simplexml. It then uses the DOMDocument createCDATASection method to properly create the appropriate bit and adds it back into the node.
$xml = new SimpleXMLElement('<?xml version="1.0" encoding="UTF-8"?><Products />');
$xml_product = $xml->addChild('product');
$newNode = $xml_product->addChild('mychild');
$mytext = "<html></html>";
$node = dom_import_simplexml($newNode);
$cdata = $node->ownerDocument->createCDATASection($mytext);
$node->appendChild($cdata);
echo $xml->asXML();
This example outputs...
<?xml version="1.0" encoding="UTF-8"?>
<Products><product><mychild><![CDATA[<html></html>]]></mychild></product></Products>
Im attempting to echo/assign a variable to the contents of the node "code" which is inside status;

$doc = new DOMDocument;
$doc->loadXML($responseXML);
echo $doc->getElementsByTagName('request-id')->item(0)->nodeValue;

I've tried simplexml looad string, but pulling hair out with this one, can anybody shed some light, speed of getting this info out in one process is quite important so not to stress the webserver out!
Many thanks.
Using DOM is a good idea, but the API methods are a little cumbersome. Using Xpath makes it a lot easier.
Xpath allows you to use expressions to fetch node lists or scalar values from a DOM:
$document = new DOMDocument;
$document->loadXML($responseXML);
$xpath = new DOMXpath($document);
$xpath->registerNamespace('example', 'http://www.example.com');
echo $xpath->evaluate('string(//example:request-id)'), "\n";
echo $xpath->evaluate('string(//example:status/#code)');
Output:
0000
201.0000
Xpath does not have a default namespace so if you XML has a namespace (like your example) you need to register a prefix for it and use it.
As code is an attribute of xml tag status, doing
getElementsByTagName('status code')
is wrong.
There's a special method for getting attribute value getAttribute:
echo $doc->getElementsByTagName('status')->item(0)->getAttribute('code');
Using XPath allows to access the status node very precisely.
DOMDocument + XPath:
$responseXML = '...';
$doc = new DOMDocument();
$doc->loadXML($responseXML);
$xp = new DOMXpath($doc);
$xp->registerNamespace('example', 'http://www.example.com');
// Every status node.
$statusNodes = $xp->query('//example:status');
// or a very specific one.
$statusNodes = $xp->query('/example:payment/example:statuses/example:status');
$statusNode = $statusNodes[0];
$code = $statusNode->getAttribute('code');
// $code is '201.0000'.
// To change the 'code' value.
$statusNode->setAttribute('code', '302.0000');
I am building up an xml file and need to include a segment of xml saved in a database (yeah, I wish that wasn't the case too).
// parent element
$parent = $dom->createElement('RecipeIngredients');
// the xml string I want to include
$xmlStr = $row['ingredientSectionXml'];
// load xml string into domDocument
$dom->loadXML( $xmlStr );
// add all Ingredient Sections from xmlStr as children of $parent
$xmlList = $dom->getElementsByTagName( 'IngredientSection' );
for ($i = $xmlList->length; --$i >= 0; ) {
$elem = $xmlList->item($i);
$parent->appendChild( $elem );
}
// add the parent to the $dom doc
$dom->appendChild( $parent );
Right now, I get the following error when I hit the line $parent->appendChild( $elem );
Fatal error: Uncaught exception 'DOMException' with message 'Wrong Document Error'
The XML in the string might look something like the following example. An important point is that there may be multiple IngredientSections, all of which need to be appended to the $parent element.
<IngredientSection name="Herbed Cheese">
<RecipeIngredient>
<Quantity>2</Quantity>
<Unit>cups</Unit>
<Item>yogurt cheese</Item>
<Note>(see Tip)</Note>
<MeasureType/>
<IngredientBrand/>
</RecipeIngredient>
<RecipeIngredient>
<Quantity>2</Quantity>
<Unit/>
<Item>scallions</Item>
<Note>, trimmed and minced</Note>
<MeasureType/>
<IngredientBrand/>
</RecipeIngredient>
<IngredientSection name="Cracked-Wheat Crackers">
</IngredientSection>
<RecipeIngredient>
<Quantity>2</Quantity>
<Unit>teaspoon</Unit>
<Item>salt</Item>
<Note/>
<MeasureType/>
<IngredientBrand/>
</RecipeIngredient>
<RecipeIngredient>
<Quantity>1 1/4</Quantity>
<Unit>cups</Unit>
<Item>cracked wheat</Item>
<Note/>
<MeasureType/>
<IngredientBrand/>
</RecipeIngredient>
</IngredientSection>
Here a two possible solutions:
Import From A Source Document
This works only if the XML string is a valid document. You need to import the document element, or any descendant of it. Depends on the part you would like to add to the target document.
$xml = "<child>text</child>";
$source = new DOMDocument();
$source->loadXml($xml);
$target = new DOMDocument();
$root = $target->appendChild($target->createElement('root'));
$root->appendChild($target->importNode($source->documentElement, TRUE));
echo $target->saveXml();
Output:
<?xml version="1.0"?>
<root><child>text</child></root>
Use A Document Fragment
This works for any valid XML fragment. Even if it has no root node.
$xml = "text<child>text</child>";
$target = new DOMDocument();
$root = $target->appendChild($target->createElement('root'));
$fragment = $target->createDocumentFragment();
$fragment->appendXml($xml);
$root->appendChild($fragment);
echo $target->saveXml();
Output:
<?xml version="1.0"?>
<root>text<child>text</child></root>
You need to use ->importNode() instead of ->appendChild(). Your XML snippets are coming from a completely different XML document, and appendChild will only accept nodes which are part of the SAME xml tree. importNode() will accept "foreign" nodes and incorporate them into the main tree.
I'm trying to parse an xml data that I'm getting via an api call. I can use file_get_contents to read into a string but simpleXML_load_string seems to fail to read it. I can save it to a file and then simpleXML_load_file works. But I would rather not write the contents to a file. I can't seem to understand how to use DOM or XMLParse with this either. I'm new to PHP and parsing XML. The output data from the api call is below.

Figured out that the issue was that what I was seeing in the browser was actually a php output with html_entiity encoded. I was able to process it with the code below which let me load it with simplexml.
$rawxml = html_entity_decode($rawxml);
$rawxml = str_replace(array(' ', "<pre>"), '', $rawxml);
$rawxml = utf8_encode($rawxml);
$xml = simplexml_load_string($rawxml);
If you XML is in a file use
simplexml_load_file
if you have it in a string use
simplexml_load_string
Then you can use the following code to access it.
<?php
$yourxml = simplexml_load_file('your.xml');
echo $yourxml->search[0]->DS_Rating;
?>
This would then output
DS3
to the browser via the 'echo' in your code. I hope this points you in the correct direction.
Try to use this:
$xml = new SimpleXMLElement('<?xml version="1.0" encoding="utf-8" ?>'.$yourXMLString);
In DOM you load the XML into a DOMDocument and create a DOMXpath instance for it.
$dom = new DOMDocument();
$dom->loadXml($xmlString);
//$dom->load($xmlFile);
$xpath = new DOMXpath($dom);
DOMXpath::evaluate() is used to fetch data from the DOM.
$rating = $dom->evaluate('string(/Search/DS_Rating)');
An Xpath expression like /Search/DS_rating always returns a node list. You can use foreach() to iterate it. The string() function in Xpath takes the first node from the list and casts it into a string. If here is not node in the list the result is an empty string.
$xmlString = <<<'XML'
<Search>
<DS_Rating>DS3</DS_Rating>

XML;
$dom = new DOMDocument();
$dom->loadXml($xmlString);
$xpath = new DOMXpath($dom);
var_dump(
$xpath ->evaluate('string(/Search/DS_Rating)')
);
Output: https://eval.in/118921
