I'm using PHP5 to create XML files. I have code like this:
$doc = new DOMDocument();
...
$xml_content = $doc->saveXML();
The problem is that created XML code starts with a root node like this one:
<?xml version="1.0"?>
But I want it to be like this:
<?xml version="1.0" standalone="yes" ?>
I guess I need to call some function on $doc, but I can't figure out which one?
You want to set
$doc->xmlStandalone = true;
It's not a function of the class, it's a property so it's a little harder to find in the docs. You can read about it here.

I tried many ways to save xml file on my filesystem, but it doesn't work. I don't know what can I do...
I only want to read an xml file, then modify the value of a node, and then save this file... But nothing happened. In PHP I don't know what the problem. In Java okay... but I need to do in PHP.
XML file:
<?xml version="1.0"?>
<node>
<pass>test</pass>
</node>
public static function saveToXML()
{
$xml = simplexml_load_file(dirname(__FILE__).'/../../../../sms_data.xml');
$xml->pass = "000";
$dom = new DOMDocument('1.0');
$dom->preserveWhiteSpace = false;
$dom->formatOutput = true;
$dom->loadXML($xml->asXML());
echo $dom->saveXML();
}
The $xml is contains the modified values. It is good, but the save function doesn't wanna work!
I tried this too: echo $dom->save('text.xml'); But nothing. It doesn't create the text.xml file... I don't know... I have been searching for the solutions on google for one day. But I don't know what the hell is going to always wrong. I didnt get nothing. The server log is empty about it...
I am so sorry to ask this. But I don't understand this code why doesn't work... why doesn't save the modification on filesystem level!
Check if the directory exists and is writable.
I am getting error while loading the xml file. I got many answers related to the topic but I really could not find why this error maybe coming in my file.
Warning: DOMDocument::load() [<a href='domdocument.load'>domdocument.load</a>]: Extra content at the end of the document
When I am running the file, it runs successfully, but when I reload it, it gives the above error instead of adding another node. But, next time when I reload it runs successfully again. This is happening alternatively. Please someone tell me why is this happening and how to solve the problem.
I am using this php code to edit the xml file:
<?php
$dom = new DomDocument("1.0", "UTF-8");
$dom->load('filename.xml');
$noteElem = $dom->createElement('note');
$toElem = $dom->createElement('to', 'Chikck');
$fromElem = $dom->createElement('from', 'ewrw');
$noteElem->appendChild($toElem);
$noteElem->appendChild($fromElem);
$dom->appendChild($noteElem);
$dom->formatOutput = TRUE;
//$xmlString = $dom->saveXML();
//echo $xmlString;
$dom->save('filename.xml');
?>
This is the xml file I am editing:
<?xml version="1.0" encoding="UTF-8"?>
<note>
<to>Chikck</to>
<from>ewrw</from>
</note>
The extra content error is caused by having two of the same node, in this case the note node, as a root element.
You could add a new root element notes for example, and then add more note elements within that.
Here's an example using the simplexml library (just because I use this one and I'm familiar with it)
New filename2.xml: (with added notes element as root)
<?xml version="1.0" encoding="UTF-8"?>
<notes>
<note>
<to>Chikck</to>
<from>ewrw</from>
</note>
</notes>
PHP script:
<?php
$xml = simplexml_load_file('filename2.xml');
$note = $xml->addChild('note');
$to = $note->addchild('to', 'Chikck');
$from = $note->addChild('from', 'ewrw');
$xml->asXML('filename2.xml');
?>
filename2.xml after running script:
<?xml version="1.0" encoding="UTF-8"?>
<notes>
<note>
<to>Chikck</to>
<from>ewrw</from>
</note>
<note>
<to>Chikck</to>
<from>ewrw</from>
</note>
</notes>
I have an XML doc that I need to load with PHP. I am currently using the simplexml_load_file() function, however the xml file is malformed, and consequently I am getting a parse error.
The XML file looks something like this:
...
</result>something1>
</else>
</else>
</resu
...
As you can see, this XML is whack and this function is throwing an error trying to parse it. Also I don't need this data that is corrupted. I would just like to read in the stuff that I can and throw everything else away.
As Jonah Bron suggested, try DOMDocument::loadHTML():
$dom = new DOMDocument();
$dom->strictErrorChecking = false;
libxml_use_internal_errors(true);
$dom->loadHTML($xml);
#Juliusz
You don't actually need to set the strictErrorChecking for this I don't think. I tried the following and it seems to work fine. To ignore the errors you need to set the libxml_use_internal_errors(true). Essentially you want to use DOMDocument instead of simplexml. I tried the following and worked without any problems:
<?php
$string = <<<XML
<?xml version='1.0'?>
<document>
<cmd>login</cmd>
<login>Richard</login>
</else>
</else>
</document>
XML;
$dom = new DOMDocument();
libxml_use_internal_errors(true);
$dom->loadHTML($string);
print $dom->saveHTML();
?>

try to tidy it up, it worked well for me.

I have created a XML file using PHP's simple XML, saved the file. When opening the file in php using fopen and printing the contents. my XML looks like this: (see below)
<?xml version="1.0" encoding="UTF-8"?>
<home><orderList><delivery_cost>0.00</delivery_cost><delivery_surname>TEST</delivery_surname><delivery_postcode>1234</delivery_postcode><status>1</status></orderList></home>
I want the xml file looking all indented and on new lines for each element. Does anybody know how to do this?
Thanks
You can do this using the formatOutput property of DOMDocument.
Save your XML like this instead, presuming your XML is in a variable called $yourXML, and you want to save it to a file at $xmlFilePath:
$dom = new DOMDocument();
$dom->loadXML($yourXML);
$dom->formatOutput = true;
$formattedXML = $dom->saveXML();
$fp = fopen($xmlFilePath,'w+');
fwrite($fp, $formattedXML);
fclose($fp);
Code adapted from here.
This is called "pretty printing" and SimpleXML does not do that. If you search on Stack Overflow and elsewhere on the web you'll find custom solutions that do that.
Pretty printing is good for visulation but I don't recommend saving documents in that format.
If you're still looking for a pretty-printer, you can try SimpleDOM's asPrettyXML()
include 'SimpleDOM.php';
$home = simpledom_load_string('<?xml version="1.0" encoding="UTF-8"?>
<home><orderList><delivery_cost>0.00</delivery_cost><delivery_surname>TEST</delivery_surname><delivery_postcode>1234</delivery_postcode><status>1</status></orderList></home>');
echo $home->asPrettyXML();
echo "\n"; for new line in xml
ob_start(); echo '
' . "\n";?>
I am trying to find out how this would work
For testing purposes, I have made two websites.
One is calling a REST service from the other
I pull the xml data with file_get_contents
if I echo it, I can see a string off data.
But how can I use simpelxml on it, extract data from the nodes themselves?
If I use simplexml_load_file($url), I get some error saying xml declaration only allowed
at the start off the document?
I have this in my testfile
<?php
$url='http://www.woonbel.nl/gps/setgpsloc';
//not working
$xml =simplexml_load_file($url);
print_r($xml);
//just a string
$xml=file_get_contents($url);
echo "<h3>$xml</h3><br>";
?>
this was the xml I send.
I send this from a class file that I included in the top off my php file
if I am sure the webservice is called, maybe that has someting to do with the declaration error?
header('Content-type: text/xml');
echo "<?xml version=\"1.0\"?>\n";
echo "<response>\n";
echo "\t<status>$status_code</status>\n";
echo "\t<fout>Geen</fout>\n";
echo "</response>";
Thanks, Richard
Sounds like there is a blank line at the top of the file, when it should start with the xml declaration. For example:
<?xml version="1.0" encoding="utf-8"?>
Have you got empty lines before the declaration?
Your REST service should be returning XML contents, something like this:
<?xml version="1.0" encoding="utf-8"?>
<results>
<result>
<value awesome="true">LOLCATS</value>
</result>
</results>
You'd then do something along these lines to consume that REST service on the other site:
$xml = simplexml_load_string(file_get_contents('http://example.com/rest.xml'));
foreach($xml->result as $result) {
$value = $result->value;
$awesome = $result->attributes()->awesome;
// do something here with our values and attributes
}
The PHP docs for SimpleXML contain more complicated/real-world examples.
For your specific XML:
$xml = simplexml_load_string(file_get_contents('http://example.com/rest.xml'));
$status = $xml->status;
$fout = $xml->fout;
The error message clearly states that there is a blank, line or character, at the beginning of the xml-data. That could be file-encoding -issue.
