Detailed analysis of PHP5 object SimpleXML _php Tutorial

Simplexml_load_file (str file); Loads an XML document into a SimpleXML object, and this method returns a handle

Simplexml_load_string (str string); Loads an XML document into a SimpleXML object that returns a handle

Simplexml_import_dom (data) This function converts a DOM node to a SimpleXML object, where data is a useful DOM node

$simplexml->addattribute (name,value) adds a property to the SimpleXML object element, note that it is a SimpleXML object element, not a SimpleXML object handle.

$simplexml->addchlid (name,value) adds a child node to the specified XML node

$simplexml->asxml () returns an XML document from a SimpleXMLElement object as a string, which can be used as an XML document to save

$simplexml->attributes () returns an array of the properties of the SimpleXML element node of the PHP5 object.

Run the above code to print out the array ([@attributes] = = Array ([name] = cx,html [tt] = DDD))

As you can see, $simplexml->attributes () gets all the attributes of an XML element node, but is contained in a [@attributes] array, so it is obtained by $xml = $xml [' @attributes '].

$simplexml->children () returns an array of children of the SimpleXML object element node

$simplexml->__construct () to create a new XML document

$simplexml->getdocnamespaces () This function returns the namespace defined by the $simplexml object

$simplexml->getname () returns the name of the $simplexml object element, which is the label signature

$simplexml->getnamespaces () returns the namespace used by the $simplexml object

$simplexml->registerxpathnamespace () This function creates a namespace context for the next XPath query

$simplexml->xpath () uses the XPath syntax to parse a PHP5 object simplexml
