(PHP Extension) Traverse the XML TreeDemonstrates how to traverse all nodes in an XML tree. Note: This example requires Chilkat v9.5.0.77 or greater.
<?php // The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number. // For example, if using Chilkat v9.5.0.48, then include as shown here: include("chilkat_9_5_0.php"); // Use the NextInTraversal2 method to traverse all nodes in the XML tree rooted at the caller. $xml = new CkXml(); $success = $xml->LoadXmlFile('qa_data/xml/twoPigs.xml'); // This is the XML traversed in this example: // <pig-rescue> // <herd name="Cathy"> // <species name="pot belly pig"> // <animal> // <name>Molly II</name> // <birth>February, 1998</birth> // <in-date>January, 2000</in-date> // <from>Middle Ave.</from> // <gender spay-neuter="yes">F</gender> // <info>Molly came from a place where an old, ill man had too many animals. // The animals were seldom fed and rats would eat the newborn piglets. // When Molly was found at one week old, she was the only piglet of // her siblings who did not get stepped on by a cow. She is a sweet, // friendly pig who likes to hang out on Cathy's porch on the lounge // pad. // </info> // </animal> // <animal> // <name>Nigel</name> // <birth>June, 1991</birth> // <in-date>August, 1991</in-date> // <from>Breeder</from> // <gender spay-neuter="no">M</gender> // <info> // Nigel was the first pig and the reason for the rescue in the // first place. He is 13 now and doing well, but takes a number // of medications, as you can see below. // </info> // </animal> // </species> // </herd> // </pig-rescue> // The sbState is an object used to keep track of the current state of the traversal. $sbState = new CkStringBuilder(); while ($xml->NextInTraversal2($sbState) != false) { print $xml->tag() . "\n"; print $xml->tagPath() . "\n"; print '' . "\n"; } // Produces the following output: // herd // herd // // species // herd|species // // animal // herd|species|animal[0] // // name // herd|species|animal[0]|name // // birth // herd|species|animal[0]|birth // // in-date // herd|species|animal[0]|in-date // // from // herd|species|animal[0]|from // // gender // herd|species|animal[0]|gender // // info // herd|species|animal[0]|info // // animal // herd|species|animal[1] // // name // herd|species|animal[1]|name // // birth // herd|species|animal[1]|birth // // in-date // herd|species|animal[1]|in-date // // from // herd|species|animal[1]|from // // gender // herd|species|animal[1]|gender // // info // herd|species|animal[1]|info // ?> |
