How to XML to Php - php

How to write php so I know the link here?
There will always be different links
<response>
<redirect>
http://www.example.com/
</redirect>
<code>0</code>
<description>OK</description>
</response>


try simplexml
$xml ='<response>
<redirect>
http://www.example.com/
</redirect>
<code>0</code>
<description>OK</description>
</response>';
$xml = simplexml_load_string($xml);
echo $xml->redirect; // http://www.example.com/


simplexml_load_string
This should answer all your questions...
http://www.php.net/manual/en/function.simplexml-load-string.php


Use DOM+Xpath:
$xml = <<<'XML'
<response>
<redirect>http://www.example.com/</redirect>
<code>0</code>
<description>OK</description>
</response>
XML;
$dom = new DOMDocument();
$dom->loadXml($xml);
$xpath = new DOMXpath($dom);
var_dump($xpath->evaluate('string(/response/redirect)'));
Output:
string(23) "http://www.example.com/"

php DOMDocument get part of xml as xml

i have the following xml
<HEAD>
<Body attribute3="3" attribute1="1" attribute2="2">
<Response id="4" status="OK">
<Token c="c" b="b" a="a" e="e" d="d">
</Token>
</Response>
</Body>
</HEAD>
and i used simplexml to manipulate it.The problem is that i have to Canonicalize XML nodes which is supported by DOMDocument.
With simplexml i used $xml->Body->Response->asXML(); to get the Response node as XML.
I am trying to get Response node as XML with DOMDocument but i don't know how
so far i have
$xmlDoc = new DOMDocument();
$xmlDoc->loadXML($Response);
$xmlDoc->C14N();
$xmlDoc->formatOutput = true;
$xml_string = $xmlDoc->saveXML();
an in $xml_string i have the xml
i want to get Response node as XML with DOMDocument
<Response id="4" status="OK">
<Token c="c" b="b" a="a" e="e" d="d">
</Token>
</Response>
can anyone help me how to do that
Any help appreciated

If I understand you correctly, this should get you there:
$XMLDoc = new DOMDocument();
$XMLDoc->loadXML($response);
$xpath = new DOMXPath($XMLDoc);
$target = $xpath->query('//Response');
echo $XMLDoc->saveXML($target[0]);
Output:
<Response id="4" status="OK">
<Token c="c" b="b" a="a" e="e" d="d">
</Token>
</Response>

PHP Xpath return zero match

Considering this XML
<?xml version="1.0" encoding="UTF-8"?>
<Assertion xmlns="urn:oasis:names:tc:SAML:2.0:assertion" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="urn:oasis:names:tc:SAML:2.0:assertion http://docs.oasis-open.org/security/saml/v2.0/saml-schema-assertion-2.0.xsd" ID="_a75adf55-01d7-40cc-929f-dbd8372ebdfc" IssueInstant="2009-09-09T00:46:02Z" Version="2.0">
<Subject>
<NameID>801234567890</NameID>
</Subject>
....
</Assertion>
PHP
$dom = new DOMDocument();
$ret = $dom->loadXML($data);
$xp = new DOMXPath($dom);
$node_list = $xp->query('/Assertion');
$node_list->length return 0 element. I want to extract the DOMElement but somehow it didn't work.

As stated on the comments by Sami Kuhmonen you may need to register the namespaces, here is an example:
<?php
$string= <<<XML
<?xml version="1.0" encoding="UTF-8"?>
<Assertion xmlns="urn:oasis:names:tc:SAML:2.0:assertion" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="urn:oasis:names:tc:SAML:2.0:assertion http://docs.oasis-open.org/security/saml/v2.0/saml-schema-assertion-2.0.xsd" ID="_a75adf55-01d7-40cc-929f-dbd8372ebdfc" IssueInstant="2009-09-09T00:46:02Z" Version="2.0">
<Subject>
<NameID>801234567890</NameID>
</Subject>
</Assertion>
XML;
$dom = new DOMDocument();
$dom->loadXML($string);
$xp = new DOMXPath($dom);
// registering the namespaces
$xp->registerNamespace('a','urn:oasis:names:tc:SAML:2.0:assertion');
$xp->registerNamespace('b','http://www.w3.org/2001/XMLSchema-instance');
// using the prefix of the registered namespace in the xpath expression
$node_list = $xp->query('/a:Assertion');
print $node_list->length
?>

Missing formatting after adding childnode?

I'm trying to add a childnode in an XML document with PHP and got it OK so far except one thing. Can't get it formatted correct?
Here is the script:
$xmldoc = new DOMDocument();
$xml->formatOutput = true;
$xml->preserveWhiteSpace = false;
$xmldoc->loadXML('<?xml version="1.0" encoding="ISO-8859-1"?>
<data>
<udate>1347730639</udate>
<userid>3</userid>
</data>');
echo "<xmp>OLD:\n". $xmldoc->saveXML() ."</xmp>";
$root = $xmldoc->firstChild;
$newElement = $xmldoc->createElement('popup');
$root->appendChild($newElement);
$newText = $xmldoc->createTextNode("0");
$newElement->appendChild($newText);
echo "<xmp>NEW:\n". $xmldoc->saveXML() ."</xmp>";
After adding the node I get this:
<data>
<udate>1347730639</udate>
<userid>3</userid>
<popup>0</popup></data>
I want it to be like this:
<data>
<udate>1347730639</udate>
<userid>3</userid>
<popup>0</popup>
</data>
Where do I go wrong?
Please help and thanks in advance :-)

createElement will break formatOutput this is a general issue
See PHP BUG Report
formatOutput does not work with saveHTML
DOMDocument->formatOutput = true does not work
But you can have a work around by reloading and formatting it.
$xmldoc = new DOMDocument();
$xmldoc->loadXML('<?xml version="1.0" encoding="ISO-8859-1"?>
<data>
<udate>1347730639</udate>
<userid>3</userid>
</data>');
echo "<xmp>OLD:\n". $xmldoc->saveXML() ."</xmp>";
$root = $xmldoc->firstChild;
$newElement = $xmldoc->createElement('popup');
$root->appendChild($newElement);
$newText = $xmldoc->createTextNode("0");
$newElement->appendChild($newText);
$xml = new DOMDocument();
$xml->preserveWhiteSpace = false;
$xml->formatOutput = true;
$xml->loadXML( $xmldoc->saveXML());
echo "<xmp>NEW:\n". $xml->saveXML()."</xmp>";
Output
OLD:
<?xml version="1.0" encoding="ISO-8859-1"?>
<data>
<udate>1347730639</udate>
<userid>3</userid>
</data>
NEW:
<?xml version="1.0" encoding="ISO-8859-1"?>
<data>
<udate>1347730639</udate>
<userid>3</userid>
<popup>0</popup>
</data>

You might want to try removing all whitespace before and then formatting.
force it to remake the xml from scratch.
$xml->preserveWhiteSpace = false;
$xml->formatOutput = true;

SimpleXML PHP - Why DOM functions don't work, cdata trouble

Ive been trying every way possible to create cdata entries in my xml. My latest attempt is as follows. I can't even get passed for the first statement where im creating a new DOMDocument. Any ideas?
<?php
$xml = '
<?xml version="1.0" encoding="ISO-8859-1"?>
<cars>
<make name="Ford">
<model>Mustang</model>
</make>
<make name="Honda">
<model>Accord</model>
</make>
</cars>
';
$dom = new DOMDocument;
$dom->loadXML($xml);
$xml = simplexml_import_dom($dom);
print "working";
?>

You should not have any characters before the XML declaration. Remove the line break at $xml = '.
The neatest solution would be to use heredoc syntax:
$xml = <<<XML
<?xml version="1.0" encoding="ISO-8859-1"?>
<cars>
<make name="Ford">
<model>Mustang</model>
</make>
<make name="Honda">
<model>Accord</model>
</make>
</cars>
XML;

Have a look at: DOMDocument::createCDATASection
$xml = '<?xml version="1.0" encoding="ISO-8859-1"?>
<cars>
<make name="Ford">
<model>Mustang</model>
</make>
<make name="Honda">
<model>Accord</model>
</make>
</cars>
';
$dom = new DOMDocument;
$dom->loadXML($xml);
$cdataNode = $dom->createCDATASection('<&>');
$dom->documentElement->appendChild($cdataNode);
echo $dom->saveXml();
Output:
<?xml version="1.0" encoding="ISO-8859-1"?>
<cars>
<make name="Ford">
<model>Mustang</model>
</make>
<make name="Honda">
<model>Accord</model>
</make>
<![CDATA[<&>]]></cars>

Removing a node from xml file

I have an xml file
<?xml version="1.0"?>
<category>
<name>SWEATERS</name>
<name>WATCHES</name>
<name>PANTS</name>
<name>test</name>
<name>1</name>
</category>
How i can remove the node <name>test</name> using xpath ,xquery and php. I used this code
$name='test;
$xmlfile="config/shop_categories.xml";
$xml = simplexml_load_file($xmlfile);
$target = $xml->xpath('/category[name="'.trim($name).'"]');
print_r($target[0]);
if($target == false)
return;
$domRef = dom_import_simplexml($target[0]); //Select position 0 in XPath array
$domRef->parentNode->removeChild($domRef);
$dom = new DOMDocument('1.0');
$dom->preserveWhiteSpace = false;
$dom->formatOutput = true;
$dom->loadXML($xml->asXML());
$dom->save($xmlfile);
But it is not working.

Pretty sure this is a duplicate, but am too lazy to find it. Here you go:
$xml = <<< XML
<?xml version="1.0"?>
<category>
<name>SWEATERS</name>
<name>WATCHES</name>
<name>PANTS</name>
<name>test</name>
<name>1</name>
</category>
XML;
$dom = new DOMDocument;
$dom->loadXML($xml);
$xPath = new DOMXPath($dom);
foreach($xPath->query('//name[text() = "test"]') as $node) {
$node->parentNode->removeChild($node);
}
echo $dom->saveXML();
Output:
<?xml version="1.0"?>
<category>
<name>SWEATERS</name>
<name>WATCHES</name>
<name>PANTS</name>
<name>1</name>
</category>
