How to remove Children from Xpath Expression Nodes in Node.JS

You probably don’t need me to explain the significance behind removing Xpath node children. Rather, you need me to save your bacon with a foolproof way to implement this functionality in Node.JS. Well, here’s how to do it.

Add this reference to package.json to install the client.

"dependencies": {
    "cloudmersive-convert-api-client": "^2.1.6"
  }

Call convertDataXmlEditRemoveAllChildNodesWithXPath:

var CloudmersiveConvertApiClient = require('cloudmersive-convert-api-client');
var defaultClient = CloudmersiveConvertApiClient.ApiClient.instance;
// Configure API key authorization: Apikey
var Apikey = defaultClient.authentications['Apikey'];
Apikey.apiKey = 'YOUR API KEY';
// Uncomment the following line to set a prefix for the API key, e.g. "Token" (defaults to null)
//Apikey.apiKeyPrefix = 'Token';
var apiInstance = new CloudmersiveConvertApiClient.ConvertDataApi();
var inputFile = "/path/to/file"; // File | Input XML file to perform the operation on.
var xPathExpression = "xPathExpression_example"; // String | Valid XML XPath query expression
var callback = function(error, data, response) {
if (error) {
console.error(error);
} else {
console.log('API called successfully. Returned data: ' + data);
}
};
apiInstance.convertDataXmlEditRemoveAllChildNodesWithXPath(inputFile, xPathExpression, callback);

And with that, we just need to give it an inputFile and xPathExpression. Then the children will be deleted, leaving the nodes themselves intact.
