(PHP Extension) Demonstrates the ChilkatPath XML MethodDemonstrates how to use the ChilkatPath method. This example uses the XML sample file pigs.xml. The pigs.xml file contains this content:
<?php include("chilkat.php"); // Use "chilkat_9_5_0.php" for versions of Chilkat < 10.0.0 $xml = new CkXml(); $success = $xml->LoadXmlFile('qa_data/xml/pigs.xml'); if ($success != true) { print $xml->lastErrorText() . "\n"; exit; } // Get the content of the "species" node for the 1st animal: $result = $xml->chilkatPath('animal|species|*'); // Output should be "pot belly pig" print $result . "\n"; // Get the content of the "type" node for the 2nd animal: // Indexing begins at 0. Therefore, the 2nd direct child having // the tag "animal" is at index 1 $result = $xml->chilkatPath('animal[1]|type|*'); // Output should be "House Pig" print $result . "\n"; // Find the pig having the name "Nigel" and display the // birth date. To do this, we'll navigate to the node having // tag="name" with the exact content "Nigel", then navigate up, // and finally navigate back down to the "birth" node: $result = $xml->chilkatPath('/C/name,Nigel|..|birth|*'); // Output should be "June, 1991" print $result . "\n"; // Navigate to the 1st animal's picture and print the filename, // description, and caption. // The "$" updates the caller's internal pointer to reference // the node that is the result of evaluating the path. // An empty string is returned for success, and a NULL/nil/0 // pointer (reference) is returned on failure. $result = $xml->chilkatPath('animal|picture|$'); if ($xml->get_LastMethodSuccess() != true) { print 'Failed to navigate to animal|picture.' . "\n"; exit; } // Display the contents of the file/description/caption child nodes print 'Picture Info:' . "\n"; print $xml->getChildContent('file') . "\n"; print $xml->getChildContent('description') . "\n"; print $xml->getChildContent('caption') . "\n"; // Return back to the root of the XML document: $xml->GetRoot2(); // Display the value of the "spay-neuter" attribute of the 1st animal: print '----' . "\n"; $result = $xml->chilkatPath('animal|gender|(spay-neuter)'); print $result . "\n"; ?> |
