I have a problem. I wrote this code but I can't read <![CDATA[Epsilon Yayınları]]>. Items with cdata, when I get them it's empty. Is there an alternative solution?
XML:
<urunler>
<urun>
<stok_kod>9789753314930</stok_kod>
<urun_ad><![CDATA[Kırmızı Erik]]></urun_ad>

$xml = new XMLReader;
$xml->open(DIR_DOWNLOAD . 'xml/'.$xml_info['xml_file_name']);
$doc = new DOMDocument;
$product_data = array();
$i=0;
while ($xml->read() && $xml->name !== 'urun');
while ($xml->name === 'urun') { $i++;
$node = simplexml_import_dom($doc->importNode($xml->expand(), true));
var_dump($node->urun_ad); die();
Dump print:
object(SimpleXMLElement)#143 (1) {
[0]=>
object(SimpleXMLElement)#145 (0) {
}
}
It just comes down to how your printing out the value. If you change the var_dump to either of the following, you will get what your after...
//var_dump($node->urun_ad)
echo $node->urun_ad.PHP_EOL;
echo $node->urun_ad->asXML().PHP_EOL;
outputs...
Kırmızı Erik
<urun_ad><![CDATA[Kırmızı Erik]]></urun_ad>
One thing to note is that if you want to use the value in another method, you may have to cast it to a string (echo does this automatically). So the first one would be (for example)...
$urun_ad = (string)$node->urun_ad;

I've been trying unsuccessfully with PHP to loop through two XML files and print the result to the screen. The aim is to take a country's name and output its regions/states/provinces as the case may be.
The first block of code successfully prints all the countries but the loop through both files gives me a blank screen.
The countries file is in the format:
<row>
<id>6</id>
<name>Andorra</name>
<iso2>AD</iso2>
<phone_code>376</phone_code>
</row>
And the states.xml:
<row>
<id>488</id>
<name>Andorra la Vella</name>
<country_id>6</country_id>
<country_code>AD</country_code>
<state_code>07</state_code>
</row>
so that country_id = id.
This gives a perfect list of countries:
$xml = simplexml_load_file("countries.xml");
$xml1 = simplexml_load_file("states.xml");
foreach($xml->children() as $key => $children) {
print((string)$children->name); echo "<br>";
}
This gives me a blank screen except for the HTML stuff on the page:
$xml = simplexml_load_file("countries.xml");
$xml1 = simplexml_load_file("states.xml");
$s = "Jamaica";
foreach($xml->children() as $child) {
foreach($xml1->children() as $child2){
if ($child->id == $child2->country_id && $child->name == $s) {
print((string)$child2->name);
echo "<br>";
}
}
}
Where have I gone wrong?
Thanks.
I suspect your problem is not casting the name to a string before doing your comparison. But why are you starting the second loop before checking if it's needed? You're looping through every single item in states.xml needlessly.
$countries = simplexml_load_file("countries.xml");
$states = simplexml_load_file("states.xml");
$search = "Jamaica";
foreach($countries->children() as $country) {
if ((string)$country->name !== $search) {
continue;
}
foreach($states->children() as $state) {
if ((string)$country->id === (string)$state->country_id) {
echo (string)$state->name . "<br/>";
}
}
}
Also, note that naming your variables in a descriptive manner makes it much easier to figure out what's going on with code.
You could probably get rid of the loops altogether using an XPath query to match the sibling value. I don't use SimpleXML, but here's what it would look like with DomDocument:
$search = "Jamaica";
$countries = new DomDocument();
$countries->load("countries.xml");
$xpath = new DomXPath($countries);
$country = $xpath->query("//row[name/text() = '$search']/id/text()");
$country_id = $country[0]->nodeValue;
$states = new DomDocument();
$states->load("states.xml");
$xpath = new DomXPath($states);
$states = $xpath->query("//row[country_id/text() = '$country_id']/name/text()");
foreach ($states as $state) {
echo $state->nodeValue . "<br/>";
}
I am trying to get elements from this XML content but returns empty:
<results>
<error>
<string>i</string>
<description>Make I uppercase</description>
<precontext></precontext>
<suggestions>
<option>I</option>
</suggestions>
<type>grammar</type>
</error>
</results>
And this is my code to extract element type of grammar :
$dom = new DOMDocument();
$dom->loadXml($output);
$params = $dom->getElementsByTagName('error'); // Find Sections
$k=0;
foreach ($params as $param) //go to each section 1 by 1
{
if($param->type == "grammar"){
echo $param->description;
}else{
echo "other type";
}
Problem is the script returns empty.
you can use simplexml_load_string()
$output = '<results>
<error>
<string>i</string>
<description>Make I uppercase</description>
<precontext></precontext>
<suggestions>
<option>I</option>
</suggestions>
<type>grammar</type>
</error>
</results>';
$xml = simplexml_load_string($output);
foreach($xml->error as $item)
{
//echo (string)$item->type;
if($item->type == "grammar"){
echo $item->description;
}else{
echo "other type";
}
}
You apparently haven't configured PHP to report errors because your code triggers:
Notice: Undefined property: DOMElement::$type
You need to grab <type> the same way you grab <error>, using DOM methods like e.g. getElementsByTagName(). Same for node value:
if ($param->getElementsByTagName('type')->length && $param->getElementsByTagName('type')[0]->nodeValue === 'grammar') {
// Feel free to add additional checks here:
echo $param->getElementsByTagName('description')[0]->nodeValue;
}else{
echo "other type";
}
Demo
I think is this what you want.
<?php
$output = '<results>
<error>
<string>i</string>
<description>Make I uppercase</description>
<precontext></precontext>
<suggestions>
<option>I</option>
</suggestions>
<type>grammar</type>
</error>
</results>';
$dom = new DOMDocument();
$dom->loadXml($output);
$params = $dom->getElementsByTagName('error'); // Find Sections
$k=0;
foreach ($params as $param) //go to each section 1 by 1
{
$string = $param->getElementsByTagName( "string" )->item(0)->nodeValue;
$description = $param->getElementsByTagName( "description" )->item(0)->nodeValue;
$option = $param->getElementsByTagName( "option" )->item(0)->nodeValue;
$type = $param->getElementsByTagName( "type" )->item(0)->nodeValue;
echo $type;
if($type == "grammar"){
echo $description ;
}else{
echo "other type";
}
}
?>
You're mixing DOM with SimpleXML. This is possible, but you would need to convert the DOM element node into a SimpleXML instance with simplexml_import_dom().
Or you use Xpath. getElementsByTagName() is a low level DOM method. Using Xpath expressions allows for more specific access with a lot less code.
$document = new DOMDocument();
$document->loadXML($xml);
$xpath = new DOMXpath($document);
foreach ($xpath->evaluate('//error') as $error) {
var_dump(
[
'type' => $xpath->evaluate('string(type)', $error),
'description' => $xpath->evaluate('string(description)', $error)
]
);
}
Output:
array(2) {
["type"]=>
string(7) "grammar"
["description"]=>
string(16) "Make I uppercase"
}
Xpath expressions allow for conditions as well, for example you could fetch all grammar errors using //error[#type = "grammar"].
Using the following xml: http://www.bnr.ro/nbrfxrates.xml
How can I get the EUR value?
Been trying like this ... but no luck.
$xmlDoc = new DOMDocument();
$xmlDoc->load('http://www.bnr.ro/nbrfxrates.xml');
$searchNode = $xmlDoc->getElementsByTagName("Cube");
var_dump($searchNode);
foreach ($searchNode as $searchNode) {
$valueID = $searchNode->getAttribute('Rate');
echo $valueID;
}
Check this
<?php
$xmlDoc = new DOMDocument();
$xmlDoc->load('http://www.bnr.ro/nbrfxrates.xml');
foreach ($xmlDoc->getElementsByTagName('Rate') as $searchNode) {
if($searchNode->getAttribute('currency') === 'EUR') {
echo $searchNode->nodeValue;
}
}
?>
First Rate is not an attribute but an element. So you would need another getElementsByTagName('Rate') and loop over it. However the XML uses a default namespace so getElementByTagNameNS('http://www.bnr.ro/xsd', 'Rate') would be the correct way.
An easier way is to use Xpath to fetch the value directly:
$document = new DOMDocument();
$document->load('http://www.bnr.ro/nbrfxrates.xml');
$xpath = new DOMXpath($document);
$xpath->registerNamespace('r', 'http://www.bnr.ro/xsd');
var_dump(
$xpath->evaluate('number(//r:Cube/r:Rate[#currency="EUR"])')
);
Output:
float(4.4961)
Xpath does not have a default namespace, so you have to register your own alias for it (I used r in the example.).
The Xpath expression
fetch any {http://www.bnr.ro/nbrfxrates.xml}Cube
//r:Cube
fetch all {http://www.bnr.ro/nbrfxrates.xml}Rate children
//r:Cube/r:Rate
filter by the currency attribute
//r:Cube/r:Rate[#currency="EUR"]
cast the first found node into a number
number(//r:Cube/r:Rate[#currency="EUR"])
<?php
$xmlDoc = new DOMDocument();
$xmlDoc->load('http://www.bnr.ro/nbrfxrates.xml');
foreach($xmlDoc->getElementsByTagName("Rate") as $node)
{
$currency = $node->getAttribute('currency');
if($currency == 'EUR')
{
$value = $node->nodeValue;
}
}
echo 'value for EUR is - '. $value;
?>
I am doing some xpath, and I can't get any result,
My code:
$html = file_get_contents($url);
$doc = new DOMDocument;
#$doc->loadHTML($html);
$xpath = new DOMXpath($doc);
$qq = ('/html/head');
$result_rows = $xpath->query($qq);
var_dump ($result_object);
echo '<br>debug begin<br>';
foreach ($result_rows as $result_object)
{
echo 'for each foreach<br>';
echo $result_object->nodeValue;
}
echo '<br>debug end<br>';
Result:
object(DOMNodeList)#3 (1) { ["length"]=> int(0) }
debug begin
debug end
He doesn't step in on foreach cycle, because he's on the result there is no "for each foreach"
Result that it should be:
debug begin
<meta charset="UTF-8">
debug end
1. Remove the # in front of #$doc->loadHTML($html);
2. Fix the 99999 of errors (as per your comment). (read the error messages! Tell us what they are.)
3. Only then will $html actually hold html data that can then be read into a XML/DOM document.
Now you are failing in getting the HTML. And you are reading in an empty string into the XML/DOM document. And that on its turn is why your XPATH is returning empty... because the entire HTML is not there.
edit:
For more info why your site isn't loaded into XML/DOM, change #$doc->loadHTML($html); into this:
if (!$doc->loadHTML($html)) {
foreach (libxml_get_errors() as $error) {
print_r($error);
}
libxml_clear_errors();
}
Anyway, it is expecting HTML. So if you already know it's not HTML, then there is your problem.
Try echoing out the nodeValue property of the result object you're returning, e.g:
foreach ($result_rows as $result_object) {
echo $result_object->nodeValue;
}
OK, after the edit, I think you need to send each of the members of the DomNodeList into an array, and then loop through that array. E.g:
$query_result = array(); //Set up an empty array
foreach($result_rows as $result_object){
//take results of xpath query and send to this array
$query_result[] = $result_object-> nodeValue;
}
echo '<br>debug begin<br>';
foreach ($query_result as $r){
echo 'for each foreach<br>';
echo $r;
}
echo '<br>debug end<br>';
I'm having difficulty extracting a single node value from a nodelist.
My code takes an xml file which holds several fields, some containing text, file paths and full image names with extensions.
I run an expath query over it, looking for the node item with a certain id. It then stores the matched node item and saves it as $oldnode
Now my problem is trying to extract a value from that $oldnode. I have tried to var_dump($oldnode) and print_r($oldnode) but it returns the following: "object(DOMElement)#8 (0) { } "
Im guessing the $oldnode variable is an object, but how do I access it?
I am able to echo out the whole node list by using: echo $oldnode->nodeValue;
This displays all the nodes in the list.
Here is the code which handles the xml file. line 6 is the line in question...
$xpathexp = "//item[#id=". $updateID ."]";
$xpath = new DOMXpath($xml);
$nodelist = $xpath->query($xpathexp);
if((is_null($nodelist)) || (! is_numeric($nodelist))) {
$oldnode = $nodelist->item(0);
echo $oldnode->nodeValue;
//$imgUpload = strchr($oldnode->nodeValue, ' ');
//$imgUpload = strrchr($imgUpload, '/');
//explode('/',$imgUpload);
//$imgUpload = trim($imgUpload);
$newItem = new DomDocument;
$item_node = $newItem ->createElement('item');
//Create attribute on the node as well
$item_node ->setAttribute("id", $updateID);
$largeImageText = $newItem->createElement('largeImgText');
$largeImageText->appendChild( $newItem->createCDATASection($largeImgText));
$item_node->appendChild($largeImageText);
$urlANode = $newItem->createElement('urlA');
$urlANode->appendChild( $newItem->createCDATASection($urlA));
$item_node->appendChild($urlANode);
$largeImg = $newItem->createElement('largeImg');
$largeImg->appendChild( $newItem->createCDATASection($imgUpload));
$item_node->appendChild($largeImg);
$thumbnailTextNode = $newItem->createElement('thumbnailText');
$thumbnailTextNode->appendChild( $newItem->createCDATASection($thumbnailText));
$item_node->appendChild($thumbnailTextNode);
$urlB = $newItem->createElement('urlB');
$urlB->appendChild( $newItem->createCDATASection($urlA));
$item_node->appendChild($urlB);
$thumbnailImg = $newItem->createElement('thumbnailImg');
$thumbnailImg->appendChild( $newItem->createCDATASection(basename($_FILES['thumbnailImg']['name'])));
$item_node->appendChild($thumbnailImg);
$newItem->appendChild($item_node);
$newnode = $xml->importNode($newItem->documentElement, true);
// Replace
$oldnode->parentNode->replaceChild($newnode, $oldnode);
// Display
$xml->save($xmlFileData);
//header('Location: index.php?a=112&id=5');
Any help would be great.
Thanks
Wasn't it supposed to be echo $oldnode->firstChild->nodeValue;? I remember this because technically you need the value from the text node.. but I might be mistaken, it's been a while. You could give it a try?
After our discussion in the comments on this answer, I came up with this solution. I'm not sure if it can be done cleaner, perhaps. But it should work.
$nodelist = $xpath->query($xpathexp);
if((is_null($nodelist)) || (! is_numeric($nodelist))) {
$oldnode = $nodelist->item(0);
$largeImg = null;
$thumbnailImg = null;
foreach( $oldnode->childNodes as $node ) {
if( $node->nodeName == "largeImg" ) {
$largeImg = $node->nodeValue;
} else if( $node->nodeName == "thumbnailImg" ) {
$thumbnailImg = $node->nodeValue;
}
}
var_dump($largeImg);
var_dump($thumbnailImg);
}
You could also use getElementsByTagName on the $oldnode, then see if it found anything (and if a node was found, $oldnode->getElementsByTagName("thumbnailImg")->item(0)->nodeValue). Which might be cleaner then looping through them.
