PHP : Function Reference : DOM Functions : DOMDocument->load()

DOMDocument->load()

Load XML from a file ()

DOMDocument{
mixedload(stringfilename,
intoptions);

}

Loads an XML document from a file.

Parameters

filename

The path to the XML document.

Return Values

Returns TRUE on success or FALSE on failure. If called statically, returns a DOMDocument but also causes an E_STRICT warning.

Errors/Exceptions

If an empty string is passed as the filename or an empty file is named, a warning will be generated. This warning is not generated by libxml and cannot be handled using libxml's error handling functions.

Examples

<?php
$doc
= new DOMDocument();
$doc->load('book.xml');
echo
$doc->saveXML();
?>

Suppose you wanted to dynamically load an array from an .XSD file. This method is your guy. just remember to use the actual xs: portion in xpaths and such.
All the other "load" methods will error out.
<?php
$attributes = array();
$xsdstring = "/htdocs/api/xsd/common.xsd";
$XSDDOC = new DOMDocument();
$XSDDOC->preserveWhiteSpace = false;
if ($XSDDOC->load($xsdstring))
{
$xsdpath = new DOMXPath($XSDDOC);
$attributeNodes =
             $xsdpath->
             query('//xs:simpleType[@name="attributeType"]')
             ->item(0);
foreach ($attributeNodes->childNodes as $attr)
{
$attributes[ $attr->getAttribute('value') ] = $attr->getAttribute('name');
}
unset($xsdpath);
}
print_r($attributes);
?>

Note that this method uses the local file system before doing anything remote. The 'disadvantage' would be that if you would do the following:
<?php
$xml = new DOMDocument;
$xml->load("xmlsource/news.php");
?>
This would not make the method read the actual output of the news.php file --presumably valid xml data--, but the file contents --obviously this would be php code. So this will return an error saying news.php is missing the xml declaration and maybe the xml start-tag
What would work is the following:
<?php
$xml = new DOMDocument;
$xml->load("http://my.beautiful-website.com/xmlsource/news.php");
?>
This will force a http request to be used to get this file instead of just locally reading it and the file just returning code

In reply to BadGuy [at] BadGuy [dot] nl
When the news.php file is located on the same server, like you said in the first example then http://my.beautiful-website.com/xmlsource/news.php wouldn't work, but you should use http://localhost/xmlsource/news.php or http://127.0.0.1/xmlsource/news.php

BadGuy´s note may be confusing since what he depicts is no special property of the relevant method. PHP works always in and on a local file system which means that if you want to use resources from other systems or - what is, indeed, BadGuy´s problem - need resources that have been dealt with by other programs or processes, you have to state and manage that explicitly in your code. PHP is just a quite normal program in that.
BadGuy´s solution is using the "http wrapper" to get output from another process (see "wrappers" in the PHP manual). Doing this, the appropriate syntax for http calls has to be respected.
