// Version 1.31
// Dec 30 2011
// List of Recent modifications
// Added nodeType,and htmlEncodedNodeContent keyes to the array that
// Search function prints.
// Generate error on non-existant source nodes when copying
// Added line number in error string using debug_bactrace.
// Made output of errors the default behaviour the default mode using trigger_error
// Added a public static variable boolean variable debug, to toggle error reporting.
// Added a search function that accepts a nodename and return the nodes with that
// name together with the actual php code that is required to access those nodes
// Added crxml::factory static method to create crxml objects on the
// fly from a raw xml string. to use with append ,appendTo, replaceWith
// functions.
// Fixed bug in fullNode function when the called from topmost document
// node
// Modified the behaviour of crxml node to crxml node assignment
// Now simply assigining a crxml node to another crxml node will
// replace the node inner content with source nodes inner content.
// all the attributes of destination will be cleared and attributes
// from source is copied to destination node.The node name of
// destination node remains the same.
// If needed to append childeren of one node to another node
// have to call $node->appendChildren($sourceNode) function.
// If you have to compleatly replace one node with another node
// You have to use the $node->replaceWith($sourcenode) function.
// A small bug fix to prevent fatal error when non existant nodes are accessed.
// Added negative indexes
// Added Isset function
// Added function for getting errors(as mentioned below)
// Added error reporting for string access on non existant child nodes.
// Added Version and encoding option to the object Constructor
// Fixed Issue with old libxml versions when executing domxpath queries
// Fixed misc bugs
// changed the below format ..->{'prefix:localName'}($namespaceURI) to ..->{'namespaceURI|localName|prefix'}
// Added format ..->{'prefix:localName'}($namespaceURI) to add nodes of type <prf:item xmlns:prf = "http://yahoo.com".....
// Added 'addNameSpaceDefNode' function to add nodes of type <prf:item xmlns:prf = "http://yahoo.com".....
// Added remove function to remove a node
// Added emptyNode function to delete all child nodes
// Fixed minor bug in fullNode.
// Made attributes to copy while using fullNode function
// Fixed minor bug in offsetunset
// Fixed a minor bug in offsetSet
// Added fullnode function to use in xml editing.
// Added support for namespaced attributes.
// XML Parser/Generator Class
