Class Overview




This is the core of the XML_Feed_Parser package. It identifies feed types  and abstracts access to them. It is an iterator, allowing for easy access  to the entire feed.

Method Detail



	
	
__construct (Constructor)   [line 87]

	

    

    

		XML_Feed_Parser __construct(
string
$feed, [bool
$strict = false], [bool
$suppressWarnings = false], [bool
$tidy = false])
    

    


	
		Detects feed types and instantiate appropriate objects.
Our constructor takes care of detecting feed types and instantiating  appropriate classes. For now we're going to treat Atom 0.3 as Atom 1.0  but raise a warning. I do not intend to introduce full support for  Atom 0.3 as it has been deprecated, but others are welcome to.




        
Parameters:

    

    

          

        string  
        $feed  
        —
          XML serialization of the feed
      

          

        bool  
        $strict  
        —
          Whether or not to validate the feed
      

          

        bool  
        $suppressWarnings  
        —
          Trigger errors for deprecated feed types?
      

          

        bool  
        $tidy  
        —
          Whether or not to try and use the tidy library on input

current   [line 240]

	

    

    

		XML_Feed_Parser_Type current(
)
    

    


	
		Return XML_Feed_Type object for current element


    

  • Return: Object

getEntryById   [line 286]

	

    

    

		XML_Feed_Parser_Type|false getEntryById(
string
$id)
    

    


	
		Provides access to entries by ID if one is specified in the source feed.
As well as allowing the items to be iterated over we want to allow  users to be able to access a specific entry. This is one of two ways of  doing that, the other being by offset. This method can be quite slow  if dealing with a large feed that hasn't yet been processed as it  instantiates objects for every entry until it finds the one needed.




        
Parameters:

    

    

          

        string  
        $id  
        —
          Valid ID for the given feed format

getEntryByOffset   [line 310]

	

    

    

		XML_Feed_Parser_Type|false getEntryByOffset(
int
$offset)
    

    


	
		Retrieve entry by numeric offset, starting from zero.
As well as allowing the items to be iterated over we want to allow  users to be able to access a specific entry. This is one of two ways of  doing that, the other being by ID.




        
Parameters:

    

    

          

        int  
        $offset  
        —
          The position of the entry within the feed, starting from 0

key   [line 250]

	

    

    

		int key(
)
    

    


	
		For iteration -- returns the key for the current stage in the array.

next   [line 223]

	

    

    

		void next(
)
    

    


	
		Provides iteration functionality.
Of course we must be able to iterate... This function simply increases  our internal counter.

rewind   [line 269]

	

    

    

		void rewind(
)
    

    


	
		For iteration -- resets the internal counter to the beginning.

valid   [line 261]

	

    

    

		bool valid(
)
    

    


	
		For iteration -- tells whether we have reached the  end.

__call   [line 196]

	

    

    

		void __call(
string
$call, array
$attributes)
    

    


	
		Proxy to allow feed element names to be used as method names
For top-level feed elements we will provide access using methods or  attributes. This function simply passes on a request to the appropriate  feed type object.




        
Parameters:

    

    

          

        string  
        $call  
        —
          - the method being called
      

          

        array  
        $attributes  
        —

__get   [line 212]

	

    

    

		void __get(
string
$val)
    

    


	
		Proxy to allow feed element names to be used as attribute names
To allow variable-like access to feed-level data we use this  method. It simply passes along to __call() which in turn passes  along to the relevant object.




        
Parameters:

    

    

          

        string  
        $val  
        —
          - the name of the variable required

__toString   [line 346]

	

    

    

		String __toString(
)
    

    


	
		Returns a string representation of the feed.
