Introduction to SimpleXML functions in PHP

The SimpleXML function allows you to convert XML into objects.

This object can be processed by using a common attribute selector or array iterator, just like any other object.

Some of these functions require the latest PHP version.
Install
SimpleXML functions are a core component of PHP. These functions can be used without installation.

 

The code is as follows:

Copy code

<? Php // Return all content as an object $ Lib = simplexml_load_file ("cet4.xml "); // Return the obtained item node in array form $ Items = $ lib-> item; $ WordsLength = sqlserver/42852.htm target = _ blank> count ($ items ); // Obtain the node values of all nodes For ($ I = 0; $ I <$ wordsLength; $ I ++ ){ $ Word = $ items [$ I]; Echo $ word-> word. '-----'. $ word-> trans. '-----'. $ word-> phonetic. '<br/> ';  } // Combination of simplexml and xpath is omnipotent $ Words = $ lib-> xpath ("// word "); // Method for obtaining attributes Echo $ words [0] ['add']. '<br/> '; Echo $ items [0] ['pp ']; ?>
