Query Multiple XML Files using XQuery, Get Results in C#

In our previous post, we covered an iteration of the Cloudmersive Convert API which enables querying a single XML file using an XQuery query — so if you’re only looking for a single operation, head there to check it out. Below, we’ll walk through connecting to a similar iteration capable of querying multiple XML files. Check out how to connect using C# code from the Cloudmersive API Console.

The parameters for this API allow for multiple XML input files (up to 10) and require a valid XML XQuery (3.1 or earlier) query expression.

If you’re working in .NET, install the .NET SDK with the below command, and copy the first code snippet:

Install-Package Cloudmersive.APIClient.NET.DocumentAndDataConvert -Version 3.4.2
using System;
using System.Diagnostics;
using Cloudmersive.APIClient.NET.DocumentAndDataConvert.Api;
using Cloudmersive.APIClient.NET.DocumentAndDataConvert.Client;
using Cloudmersive.APIClient.NET.DocumentAndDataConvert.Model;

If you’re using .NET Core, use the below instead:

Install-Package Cloudmersive.APIClient.NETCore.DocumentAndDataConvert -Version 2.2.1
using System;
using System.Diagnostics;
using Cloudmersive.APIClient.NETCore.DocumentAndDataConvert.Api;
using Cloudmersive.APIClient.NETCore.DocumentAndDataConvert.Client;
using Cloudmersive.APIClient.NETCore.DocumentAndDataConvert.Model;

For the last step, copy in the remaining code to complete the API call, and supply your API key & XML files where indicated. For more details around parameters & response models, check out the Cloudmersive API Console page.

                Debug.WriteLine(result);
            }
            catch (Exception e)
            {
                Debug.Print("Exception when calling ConvertDataApi.ConvertDataXmlQueryWithXQueryMulti: " + e.Message );
            }
        }
    }
