How to remove Children from Xpath Expression Nodes in PHP

On today’s agenda: using PHP to set up a method for deleting the children from Xpath expression nodes.

To begin our process, we shall open the command line for Composer and paste in this command here:

composer require cloudmersive/cloudmersive_document_convert_api_client

That will install the API client that we will be using. Once that’s done with we shall proceed with calling this function here:

<?php
require_once(__DIR__ . '/vendor/autoload.php');
// Configure API key authorization: Apikey
$config = Swagger\Client\Configuration::getDefaultConfiguration()->setApiKey('Apikey', 'YOUR_API_KEY');
// Uncomment below to setup prefix (e.g. Bearer) for API key, if needed
// $config = Swagger\Client\Configuration::getDefaultConfiguration()->setApiKeyPrefix('Apikey', 'Bearer');
$apiInstance = new Swagger\Client\Api\ConvertDataApi(
// If you want use custom http client, pass your client which implements `GuzzleHttp\ClientInterface`.
// This is optional, `GuzzleHttp\Client` will be used as default.
new GuzzleHttp\Client(),
$config
);
$input_file = "/path/to/file"; // \SplFileObject | Input XML file to perform the operation on.
$x_path_expression = "x_path_expression_example"; // string | Valid XML XPath query expression
try {
$result = $apiInstance->convertDataXmlEditRemoveAllChildNodesWithXPath($input_file, $x_path_expression);
print_r($result);
} catch (Exception $e) {
echo 'Exception when calling ConvertDataApi->convertDataXmlEditRemoveAllChildNodesWithXPath: ', $e->getMessage(), PHP_EOL;
}
?>

And there you have it, our method is completely set up. From there it’s just a matter of inputting our XML file and the Xpath expression to be used. It doesn’t get any easier than that!
