Following is my XML file i want to update the doller and cent values which are inside latestBid. I first tried the doller values but it's not working. i even tried to update the description ('//item[id="4"]/description') even that didn't work. Please tell me what i'm doing wrong here.
XML file
<?xml version="1.0"?>
<items>
<item>
<itemNumber>4</itemNumber>
<latestBid>
<latestCustomerId>1</latestCustomerId>
<bidPrice>
<doller>2342</doller>
<cent>23</cent>
</bidPrice>
</latestBid>
</item>
<item>
<itemNumber>5</itemNumber>
<latestBid>
<latestCustomerId>1</latestCustomerId>
<bidPrice>
<doller>35345</doller>
<cent>78</cent>
</bidPrice>
</latestBid>
</item>
</items>
PHP file
<?php
$url = '../../data/auction2.xml';
$itemNumber ="4";
$bidDoller = 45;
$bidCent=55;
$doc = new DomDocument();
$xml=simplexml_load_file($url);
//echo "came 1";working
foreach ($xml->xpath('//item[#itemNumber="4"]/latestBid/bidPrice/doller') as $desc) {
echo "came 2";//nt working
$dom=dom_import_simplexml($desc);
$dom->nodeValue = $bidDoller;
}
file_put_contents($url, $xml->asXML());
?>
edited. Still not working
thank you every one for the support by editing and answering I finally did it. since it wasn't easy for me to do this i'm posting the answer to help someone like me :).
i didn't change the xml.
php file
$url = '../../data/auction2.xml';
$itemNumber ="4";
$bidDoller = 85;
$bidCent=95;
$xml=simplexml_load_file($url);
$resultDoller= $xml->xpath('//item[itemNumber="'.$itemNumber.'"]/latestBid/bidPrice/doller');
$resultCent= $xml->xpath('//item[itemNumber="'.$itemNumber.'"]/latestBid/bidPrice/cent');
$resultDoller[0][0]=$bidDoller;
$resultCent[0][0]=$bidCent;
print $xml->asXML();
file_put_contents($url, $xml->asXML());
Following worked for me,
//XML
<?xml version="1.0"?>
<items>
<item id="4">
<itemNumber>4</itemNumber>
<latestBid>
<latestCustomerId>1</latestCustomerId>
<bidPrice>
<doller>2342</doller>
<cent>23</cent>
</bidPrice>
</latestBid>
</item>
<item>
<itemNumber>5</itemNumber>
<latestBid>
<latestCustomerId>1</latestCustomerId>
<bidPrice>
<doller>35345</doller>
<cent>78</cent>
</bidPrice>
</latestBid>
</item>
</items>
//PHP
<?php
$url = '../../data/auction2.xml';
$itemNumber ="4";
$bidDoller = 45;
$bidCent=55;
$doc = new DomDocument();
$xml=simplexml_load_file($url);
$result = $xml->xpath('//item[#id="4"]/latestBid/bidPrice/doller');
echo "<pre>";
print_r($result);
//echo "came 1";working
foreach ($xml->xpath('//item[#id="4"]/latestBid') as $desc) {
echo "came 2";//nt working
$dom=dom_import_simplexml($desc);
$dom->nodeValue = $bidDoller;
}
//file_put_contents($url, $xml->asXML());

I have this XML:
<destinos>
<destino>
<location>Spain</location>
<programas>
<item></item>
<item></item>
</programas>
</destino>
<destino>
<location>France</location>
<programas>
<item></item>
<item></item>
</programas>
</destino>
</destinos>
I need to include or copy the value of "Location" within each "item" and I am not able to do so.
<destinos>
<destino>
<location>Spain</location>
<programas>
<item>
<location>Spain</location>
</item>
<item>
<location>Spain</location>
</item>
</programas>
</destino>
<destino>
<location>France</location>
<programas>
<item>
<location>France</location>
</item>
<item>
<location>France</location>
</item>
</programas>
</destino>
</destinos>
I have no knowledge of PHP and I have been reading but I can't find the solution.
If someone could help me and explain I would be very grateful.
My code:
$url = file_get_contents("archive.xml");
$xml = simplexml_load_string($url);
$changes = $xml->xpath("//*[starts-with(local-name(), 'item')]");
foreach ($changes as $change)
$change[0] = $xml->destinos->destino->location;
header('Content-Type: application/xml');
echo $xml->asXML();
One option could be to use xpath with addChild with with the value of the location:
$url = file_get_contents("archive.xml");
$xml = simplexml_load_string($url);
$changes = $xml->xpath("/destinos/destino");
foreach ($changes as $change) {
$text = (string)$change->location;
foreach ($change->xpath("programas/item") as $i) {
$i->addChild("location", $text);
}
}
header('Content-Type: application/xml');
echo $xml->asXML();
Output
<destinos>
<destino>
<location>Spain</location>
<programas>
<item><location>Spain</location></item>
<item><location>Spain</location></item>
</programas>
</destino>
<destino>
<location>France</location>
<programas>
<item><location>France</location></item>
<item><location>France</location></item>
</programas>
</destino>
</destinos>
Php demo
Using SimpleXML, you can just use object notation to access the various elements of the document, this stops the need for XPath and can also make the code more readable...
$url = file_get_contents("archive.xml");
$xml = simplexml_load_string($url);
foreach ($xml->destino as $destino) {
// Process each item
foreach ( $destino->programas->item as $item ) {
// Set the location from the destino location value
$item->location = (string)$destino->location;
}
}
header('Content-Type: application/xml');
echo $xml->asXML();
One thing to note is that when using SimpleXML, the root node (<destinos> in this case) is the $xml object. This is why $xml->destino is accessing the <destino> elements.
With DOM you can append clones of the location nodes to the respective item elements.
$document = new DOMDocument();
$document->load($url);
$xpath = new DOMXpath($document);
// iterate the location child of the destino elements
foreach($xpath->evaluate('//destino/location') as $location) {
// iterate the item nodes inside the same parent node
foreach ($xpath->evaluate('parent::*/programas/item', $location) as $item) {
// append a copy of the location to the item
$item->appendChild($location->cloneNode(TRUE));
}
}
echo $document->saveXML();
I am trying to parse XML with PHP. The XML is a response from ebay getsellerlist api, and is structured like so:
<!--?xml version="1.0" encoding="UTF-8"?-->
<getsellerlistresponse xmlns="urn:ebay:apis:eBLBaseComponents">
<timestamp>2016-08-11T14:17:39.869Z</timestamp>
<ack>Success</ack>
<version>967</version>
<build>E967_CORE_APISELLING_17965876_R1</build>
<itemarray>
<item>
<itemid>itemid1</itemid>
<listingdetails>
<viewitemurl>itemurl1</viewitemurl>
</listingdetails>
<primarycategory>
<categoryid>categoryid1</categoryid>
<categoryname>categoryname1</categoryname>

<title>title1</title>
<picturedetails>
<galleryurl>url1</galleryurl>
<photodisplay>thumbnail1</pictureurl>
<pictureurl>picture1</pictureurl>
</picturedetails>
</item>
</itemarray>
</getsellerlistresponse>
My php is as follows:
<?
$xml = '<!--?xml version="1.0" encoding="UTF-8"?--><getsellerlistresponse xmlns="urn:ebay:apis:eBLBaseComponents"><timestamp>2016-08-11T14:17:39.869Z</timestamp><ack>Success</ack><version>967</version><build>E967_CORE_APISELLING_17965876_R1</build><itemarray><item><itemid>itemid1</itemid><listingdetails><viewitemurl>itemurl1</viewitemurl></listingdetails><primarycategory><categoryid>categoryid1</categoryid><categoryname>categoryname1</categoryname></primarycategory><title>title1</title><picturedetails><galleryurl>url1</galleryurl><photodisplay>thumbnail1</pictureurl><pictureurl>picture1</pictureurl></picturedetails></item><item><itemid>itemid2</itemid><listingdetails><viewitemurl>itemurl2</viewitemurl></listingdetails><primarycategory><categoryid>categoryid2</categoryid><categoryname>categoryname2</categoryname></primarycategory><title>title1</title><picturedetails><galleryurl>url2</galleryurl><photodisplay>thumbnail2</pictureurl><pictureurl>picture2</pictureurl></picturedetails></item></itemarray></getsellerlistresponse>';
$dom = new DOMDocument();
$dom->loadXML($xml);
$title_nodes = $dom->getElementsByTagName('title');
$titles = array();
foreach ($title_nodes as $node) {
$titles[] = $node->nodeValue;
echo $node->nodeValue;
}
echo $titles[0];
echo count($titles);
?>
When I run it, I get a blank page, no errors, nothing.
If I check $titles length using count(), it comes back as zero.
For some reason it is not getting the title node (or any other nodes) and I can't figure out how to parse the xml string with php and get the node values.
Any help most appreciated, if the question is vague or lacking detail, please let me know and I will correct it.
The XML isn't valid:
Unable to parse any XML input. org.jdom2.input.JDOMParseException: Error on line 2: The element type "photodisplay" must be terminated by the matching end-tag "".
And that's only after you remove the comments in your XML declaration:
<!--?xml version="1.0" encoding="UTF-8"?-->
shoud be
<?xml version="1.0" encoding="UTF-8"?>

I need your help once again!
I need to read this xml file... but the problem is that it's not working!
This is the XML
<rss xmlns:media="http://search.yahoo.com/mrss/" version="2.0">
<channel>
<item>
<title>Video</title>
<media:content url="http://videourl.com/etc/" type="video/x-flv" duration="5128"/>
</item>
</channel>
</rss>
And this is my code:
<?php
$xml=simplexml_load_file("http://videourl.com/etc/");
echo $xml->getName() . "<media:content url=";
foreach($xml->children() as $child)
{
echo $child->getName() . ": " . $child . "";
}
?>
And it's not working! It's not working because nothing gets echoed, or printed! Does anyone spot the error?
<?php
$xml = '<?xml version="1.0" encoding="UTF-8" ?>
<rss>
<channel>
<item>
<title><![CDATA[Tom & Jerry]]></title>
</item>
</channel>
</rss>';
$xml = simplexml_load_string($xml);
// echo does the casting for you
echo $xml->channel->item->title;
// but vardump (or print_r) not!
var_dump($xml->channel->item->title);
// so cast the SimpleXML Element to 'string' solve this issue
var_dump((string) $xml->channel->item->title);
?>
Again i edit my code now try this
I have a small requirement where I need to create a XML file on the fly. It was no problem for me to create a normal xml file which would be looking like this:
<?xml version="1.0" encoding="UTF-8"?>
<root>
<item>
<name></name>
</item>
</root>
But my requirement is such that I need to create a XML file whose output is:
<?xml version="1.0" encoding="UTF-8"?>
<root>
<item>
<name url = "C:\htdocs\proj1\source_file1"/>
<name url = "C:\htdocs\proj1\source_file2"/>
<name url = "C:\htdocs\proj1\source_file3"/>
</item>
</root>
I have tried in this fashion:
<?php
$domtree = new DOMDocument('1.0', 'UTF-8');
$domtree->formatOutput = true;
$xmlRoot = $domtree->createElement("root");
$xmlRoot = $domtree->appendChild($xmlRoot);
$item = $domtree->createElement("item");
$item = $xmlRoot->appendChild($item);
$name= $domtree->createElement("name");
$name = $item->appendChild($name);
$sav_xml = $domtree->saveXML();
$handle = fopen("new.xml", "w");
fwrite($handle, $sav_xml);
fclose($handle);
?>
But I wanted to append/add the url="path" to my elements. I have tried declaring variables with url and path but this throws me errors like:
Uncaught exception 'DOMException' with message 'Invalid Character Error'
Any ideas how to approach this problem!
Thanks
You just have to declare that attributes via php DOM:
...
$name= $domtree->createElement("name");
$urlAttribute = $domtree->createAttribute('url');
$urlAttribute->value = 'C:\htdocs\proj1\source_file1';
$name->appendChild($urlAttribute);
$item->appendChild($name);
...
Link to DOMDocument docs
The XML
<?xml version="1.0"?>
<items version="1.5">
<item name="device">iphone</item>
<item name="affinity">testing</item>
</items>
I need to get the value 'iphone' and value 'testing' from device and affinity, how do I select them?
I've tried:
$xml = new DOMDocument();
$xml->loadXML($request);
$itemList = $xml->getElementsByTagName('item');
foreach($itemList as $install)
{
echo $install->getAttribute('device')->item(0)->nodeValue;
}
But that doesn't seem to work.
Thank you!
Something like this may do:
$Device;
$Affinity;
foreach($itemList as $install)
{
if($install->getAttribute('name') =='device'){
$Device = $install->nodeValue;
}
if($install->getAttribute('name')=='affinity'){
$Affinity = $install->nodeValue;
}
}
