simplexml_load_file - Interprets an XML file into an object

SYNOPSIS

       SimpleXMLElement  simplexml_load_file  (string  $filename, [string  $class_name = "SimpleXMLElement"], [int  $options], [string	$ns = ""],
       [bool  $is_prefix = false])

DESCRIPTION

	Convert the well-formed XML document in the given file to an object.

PARAMETERS

	      o $filename
		- Path to the XML file

	      Note

		      Libxml 2 unescapes the URI,  so  if  you	want  to  pass	e.g.   b&c  as	the  URI  parameter  a,  you  have  to	call  sim-
		     plexml_load_file(rawurlencode('http://example.com/?a='  .	urlencode('b&c'))).  Since  PHP  5.1.0	you  don't need to do this
		     because PHP will do it for you.

	      o $class_name
		- You may use this optional parameter so that simplexml_load_file(3) will return an object of  the  specified  class.  That  class
		should extend the SimpleXMLElement class.

	      o $options
		- Since PHP 5.1.0 and Libxml 2.6.0, you may also use the $options parameter to specify additional Libxml parameters.

	      o $ns
		- Namespace prefix or URI.

	      o $is_prefix
		- TRUE if $ns is a prefix, FALSE if it's a URI; defaults to FALSE.

RETURN VALUES

	Returns an object of class SimpleXMLElement with properties containing the data held within the XML document, or FALSE on failure.

ERRORS
/EXCEPTIONS
	Produces an E_WARNING error message for each error found in the XML data.

       Tip

	       Use libxml_use_internal_errors(3) to suppress all XML errors, and libxml_get_errors(3) to iterate over them afterwards.

EXAMPLES

       Example #1

	      Interpret an XML document

	      <?php
	      // The file test.xml contains an XML document with a root element
	      // and at least an element /[root]/title.

	      if (file_exists('test.xml')) {
		  $xml = simplexml_load_file('test.xml');

		  print_r($xml);
	      } else {
		  exit('Failed to open test.xml.');
	      }
	      ?>

	       This script will display, on success:

	      SimpleXMLElement Object
	      (
		[title] => Example Title
		...
	      )

	       At this point, you can go about using $xml->title and any other elements.

NAME

       Test::XML::XPath - Test XPath assertions

SYNOPSIS

	 use Test::XML::XPath tests => 3;
	 like_xpath( '<foo />', '/foo' );   # PASS
	 like_xpath( '<foo />', '/bar' );   # FAIL
	 unlike_xpath( '<foo />', '/bar' ); # PASS

	 is_xpath( '<foo>bar</foo>', '/foo', 'bar' ); # PASS
	 is_xpath( '<foo>bar</foo>', '/bar', 'foo' ); # FAIL

	 # More interesting examples of xpath assertions.
	 my $xml = '<foo attrib="1"><bish><bosh args="42">pub</bosh></bish></foo>';

	 # Do testing for attributes.
	 like_xpath( $xml, '/foo[@attrib="1"]' ); # PASS
	 # Find an element anywhere in the document.
	 like_xpath( $xml, '//bosh' ); # PASS
	 # Both.
	 like_xpath( $xml, '//bosh[@args="42"]' ); # PASS

DESCRIPTION

       This module allows you to assert statements about your XML in the form of XPath statements.  You can say that a piece of XML must contain
       certain tags, with so-and-so attributes, etc.  It will try to use any installed XPath module that it knows about.  Currently, this means
       XML::LibXML and XML::XPath, in that order.

       NB: Normally in XPath processing, the statement occurs from a context node.  In the case of like_xpath(), the context node will always be
       the root node.  In practice, this means that these two statements are identical:

	  # Absolute path.
	  like_xpath( '<foo/>', '/foo' );
	  # Path relative to root.
	  like_xpath( '<foo/>', 'foo' );

       It's probably best to use absolute paths everywhere in order to keep things simple.

       NB: Beware of specifying attributes.  Because they use an @-sign, perl will complain about trying to interpolate arrays if you don't escape
       them or use single quotes.

FUNCTIONS

       like_xpath ( XML, XPATH [, NAME ] )
	   Assert that XML (a string containing XML) matches the statement XPATH.  NAME is the name of the test.

	   Returns true or false depending upon test success.

       unlike_xpath ( XML, XPATH [, NAME ] )
	   This is the reverse of like_xpath().  The test will only pass if XPATH does not generates any matches in XML.

	   Returns true or false depending upon test success.

       is_xpath ( XML, XPATH, EXPECTED [, NAME ] )
	   Evaluates XPATH against XML, and pass the test if the is EXPECTED.  Uses findvalue() internally.

	   Returns true or false depending upon test success.

       set_xpath_processor ( CLASS )
	   Set the class name of the XPath processor used.  It is up to you to ensure that this class is loaded.

       In all cases, XML must be well formed, or the test will fail.

SEE ALSO

       Test::XML.

       XML::XPath, which is the basis for this module.

       If you are not conversant with XPath, there are many tutorials available on the web.  Google will point you at them.  The first one that I
       saw was: <http://www.zvon.org/xxl/XPathTutorial/>, which appears to offer interactive XPath as well as the tutorials.
