I have a document that it's structure is like below.
There are a lot of <entry>. My question is how can I output the <uri> of each entry? And another question, how can I output only the USERNAME?
This is the file I want to get the usernames http://search.twitter.com/search.atom?q=yankees
<?xml version="1.0" encoding="UTF-8"?>
<feed xmlns:google="http://base.google.com/ns/1.0" xml:lang="en-US" xmlns:openSearch="http://a9.com/-/spec/opensearch/1.1/" xmlns="http://www.w3.org/2005/Atom" xmlns:twitter="http://api.twitter.com/" xmlns:georss="http://www.georss.org/georss">
<entry>
<author>
<name></name>
<uri>http://twitter.com/USERNAME</uri>
</author>
</entry>
<?php
$xml = new DOMDocument;
// link to ur file
$xml->load('');
foreach ($xml->getElementsByTagName('entry') as $product )
{
$append = array();
foreach($product->getElementsByTagName('uri') as $name ) {
// Stick $name onto the array
$append[] = $name;
}
}
$result = $xml->saveXML();
print_r(str_replace('http://twitter.com/','',$result));
?>
You can use Xpath queries
http://www.php.net/manual/en/simplexmlelement.xpath.php
or
http://php.net/manual/en/domxpath.query.php
You should use SimpleXML some kind of a loop which goes trough all the s.
(foreach($xml->entry as $entry) loop should work fine, I think.)
And for the second: if it is always http://twitter.com/USERNAME, simply count the prefix's length than use a substr.
Resources to use: substr, SimpleXML, SimpleXML

I have an XML like below
<entries>
<entry>
<title lang="en">Sample</title>
<entrydate>0</entrydate>
<contents>0</contents>
<entrynum>0</entrynum>
</entry>
<entry>
<title lang="fr">Sample</title>
<entrydate>1</entrydate>
<contents>1</contents>
<entrynum>1</entrynum>
</entry>
</entries>
Is there a way in PHP to delete the parent node (entry) based on the title lang attribute? I need to keep only the en ones, so in this case I would need to get the XML without the second entry node.
I tried looking around but couldn't find any solution...
You need to use DOMDocument class to parse string to XML document. Then use DOMXpath class to find target element in document and use DOMNode::removeChild() to remove selected element from document.
$doc = new DOMDocument();
$doc->loadXML($xml);
$xpath = new DOMXpath($doc);
// select target entry tag
$entry = $xpath->query("//entry[title[#lang='fr']]")->item(0);
// remove selected element
$entry->parentNode->removeChild($entry);
$xml = $doc->savexml();
You can check result in demo
You could also read your file and generated new one with your modification
<?php
$entries = array('title' => "What's For Dinner",
'link' => 'http://menu.example.com/',
'description' => 'Choose what to eat tonight.');
print "<entries>\n";
foreach ($entries as $element => $content) {
print " <$element>";
print htmlentities($content);
print "</$element>\n";
}
print "</entries>";
?>
Use the method described in this answer, i.e.
<?php
$xml = simplexml_load_file('1.xml');
$del_items = [];
foreach ($xml->entry as $e) {
$attr = $e->title->attributes();
if ($attr && $attr['lang'] != 'en') {
$del_items []= $e;
}
}
foreach ($del_items as $e) {
$dom = dom_import_simplexml($e);
$dom->parentNode->removeChild($dom);
}
echo $xml->asXML();
Output
<?xml version="1.0" encoding="UTF-8"?>
<entries>
<entry>
<title lang="en">Sample</title>
<entrydate>0</entrydate>
<contents>0</contents>
<entrynum>0</entrynum>
</entry>
</entries>
The items cannot be removed within the first loop, because otherwise we may break the iteration chain. Instead, we collect the entry objects into $del_items array, then remove them from XML in separate loop.
I am have two xml files.. I first get one and loop through it then I need to take an id from the first xml file and find it in the second one and echo out the results associated with that id. If I were to do this with SQL I would simply do this:
$query = (SELECT * FROM HotelSummary WHERE roomTypeCode = '$id') or die();
while($row=mysql_fetch_array($query)){
$name = $row['Name'];
}
echo $name;
How can I do this is in xml and php??
I recommend you to read the DOMDocument documentation.
It's quite heavy but also powerful (not always clear what happens, but the Internet shold always give you a solution)
You can simply walk through your first document, finding your Id and then find your DOMElement via an XPath.
<?php
$dom = new DOMDocument();
$dom->load('1.xml');
foreach ($dom->getElementsByTagName('article') as $node) {
// your conditions to find out the id
$id = $node->getAttribute('id');
}
$dom = new DOMDocument();
$dom->load('2.xml');
$xpath = new DOMXPath($dom);
$element = $xpath->query("//*[#id='".$id."']")->item(0);
// would echo "top_2" based on my example files
echo $element->getAttribute('name');
Based on following test files:
1.xml
<?xml version="1.0" encoding="UTF-8"?>
<articles>
<article id="foo_1">
<title>abc</title>
</article>
<article id="foo_2">
<title>def</title>
</article>
</articles>
2.xml
<?xml version="1.0" encoding="UTF-8"?>
<tests>
<test id="foo_1" name="top_1">
</test>
<test id="foo_2" name="top_2">
</test>
</tests>
Use SimpleXML to create an object representation of the file. You can then loop through the elements of the Simple XML object.
Depending on the format of the XML file:
Assuming it is:
<xml>
<roomTypeCode>
<stuff>stuff</stuff>
<name>Skunkman</name>
</roomTypeCode>
<roomTypeCode>
<stuff>other stuff</stuff>
<name>Someone Else</name>
</roomTypeCode>
</xml>
It would be something like this:
$xml = simplexml_load_file('xmlfile.xml');
for($i = 0; $i < count($xml->roomTypeCode); $i++)
{
if($xml->roomTypeCode[$i]->stuff == "stuff")
{
$name = $xml->roomTypeCode[$i]->name;
}
}
That connects to the XML file, finds how many roomTypeCode entries there are, searches for the value of "stuff" within and when it matches it correctly, you can access anything having to do with that XML entry.
I have a XML file. Here is a small version of that.

First I would like to know how do we call something like opensearch:totalResults in XML terms.
And I need your help with obtaining following values with PHP.
<opensearch:totalResults>2338</opensearch:totalResults> I need to get 2338 to a PHP variable.
Thank you.
Thank you all for your answers.
I could fix it with following way.
$xml = simplexml_load_string($xmltext);
$val = $xml->xpath('opensearch:totalResults');
echo $val[0];
parse all of this information into PHP using DOM. Ex.
$doc = new DOMDocument;
$doc->loadXML($xml); //$xml is your xml string
echo $doc->getElementsByTagName("totalResults")->item(0)->nodeValue;
For your first question, opensearch:totalResults is the qualified name of a start tag. It is called a qualified name (you might come across this as QName) because it contains the namespace (opensearch) for the tag.
For your second question, you can easily parse your XML into a DOMDocument and then query it for the value of the relevant tag. There are lots of examples on SO and of course on Google; a basic one from PHP.net is here.
Important note: Your current XML document does not contain an XML namespace declaration for the opensearch namespace, and will not parse as a result. You need to add such a declaration by making a modification:
<feed xmlns="http://www.w3.org/2005/Atom" xml:lang="fr"
xmlns:opensearch="http://a9.com/-/spec/opensearch/1.1/">
If you need more powerful querying you can also use XPath. A minimal example would look like:
$doc = new DOMDocument();
$doc->loadXML($xml);
$xpath = new DOMXPath($doc);
$nodes = $xpath->query('//opensearch:totalResults');
foreach ($nodes as $node) {
echo $node->nodeValue;
}
opensearch is a namespace, so you can try to access it like:
$yourXml->children('openSearch', true)->totalResults
Hope it helps
Check this out the exact result in PHP
<?php
$xml ='<?xml version="1.0" encoding="UTF-8"?>
<feed xmlns="http://www.w3.org/2005/Atom" xml:lang="fr">
<title>Liste des ebooks</title>

<opensearch:totalResults>2338</opensearch:totalResults>
<opensearch:itemsPerPage>100</opensearch:itemsPerPage>
<entry>
<category term="Romans" label="Romans"/>
<category term="Aventures" label="Aventures"/>
</entry>
</feed>';
$dom = new DOMDocument();
$dom->loadXML($xml);
$xmlD = simplexml_import_dom($dom);
echo $xmlD->totalResults;
?>
Read your xml file with simplexml_load_file as an object
Then get your variable like this:
$object->{'opensearch:totalResults'};
I was tesing with a simple example of how to display XML in browser using PHP and found this example which works good
<?php
$xml = new DOMDocument("1.0");
$root = $xml->createElement("data");
$xml->appendChild($root);
$id = $xml->createElement("id");
$idText = $xml->createTextNode('1');
$id->appendChild($idText);
$title = $xml->createElement("title");
$titleText = $xml->createTextNode('Valid');
$title->appendChild($titleText);
$book = $xml->createElement("book");
$book->appendChild($id);
$book->appendChild($title);
$root->appendChild($book);
$xml->formatOutput = true;
echo "<xmp>". $xml->saveXML() ."</xmp>";
$xml->save("mybooks.xml") or die("Error");
?>
It produces the following output:
<?xml version="1.0"?>
<data>
<book>
<id>1</id>
<title>Valid</title>
</book>
</data>
Now I have got two questions regarding how the output should look like.
The first line in the xml file '', should not be displayed, that is it should be hidden
How can I display the TextNode in the next line. In total I am exepecting an output in this fashion
<data>
<book>
<id>1</id>
<title>
Valid
</title>
</book>
</data>
Is that possible to get the desired output, if so how can I accomplish that.
Thanks
To skip the XML declaration you can use the result of saveXML on the root node:
$xml_content = $xml->saveXML($root);
file_put_contents("mybooks.xml", $xml_content) or die("cannot save XML");
Please note that saveXML(node) has a different output from saveXML().
First question:
here is my post where all usable threads with answers are listed: How do you exclude the XML prolog from output?
Second question:
I don't know of any PHP function that outputs text nodes like that.
You could:
read xml using DomDocument and save each node as string
iterate trough nodes
detect text nodes and add new lines to xml string manually
At the end you would have the same XML with text node values in new line:
<node>
some text data
</node>
I am trying to parse an individual element from an XML string using PHP. The issue is that this individual element occurs before the entries start. The XML is below:
<?xml version="1.0" encoding="UTF-8"?>
<feed gd:kind="shopping#products" gd:etag=""lm_25heFT8yiumci9EH1kItJBpg/Sj5O9aXZ82PKpx3N2C3uQYMhNYE"" xmlns="http://www.w3.org/2005/Atom" xmlns:gd="http://schemas.google.com/g/2005" xmlns:openSearch="http://a9.com/-/spec/opensearchrss/1.0/" xmlns:s="http://www.google.com/shopping/api/schemas/2010">

<openSearch:startIndex>1</openSearch:startIndex>
<openSearch:itemsPerPage>25</openSearch:itemsPerPage>
<entry >...</entry>
<entry >...</entry>
</feed>
I am trying to parse out the "64" in the opensearch:totalResults tag. How do I this and assign it to a variable in php? I tried:
$url = 'url of xml feed';
$xml = simplexml_load_file($url);
$entries =$xml->entry[0]->openSearch:totalResults;
// also tried $entries =$xml->openSearch:totalResults;
echo $entries;
but it's not working. Any advice?
You need to register namespace in order to access these nodes:
$xml = simplexml_load_file('file.xml');
$xml->registerXPathNamespace('os', 'http://a9.com/-/spec/opensearchrss/1.0/');
$nodes = $xml->xpath('os:totalResults');
$totalResults = (string)$nodes[0];
You can also use http://it1.php.net/manual/en/simplexmlelement.children.php (using the $ns parameter)
that is less resource intensive.
