Remove q1 and all namespaces from xml

Question

I\'m given a xsd generated C# POCO object that I need to convert to xml. The expected payload however doesn\'t match the xsds I was given. Specifically, I need to omit the

Answer 1

The simplest way is to 'post-process' the XML:

var doc = XDocument.Parse(xml);

doc.Descendants().Attributes().Where(a => a.IsNamespaceDeclaration).Remove();

foreach (var element in doc.Descendants())
{
    element.Name = element.Name.LocalName;
}

var xmlWithoutNamespaces = doc.ToString();

The other option (as you can't amend the source class XML attributes) is to implement a decorator for XmlWriter that ignores all namespaces, but it's quite a large class so there'd be a lot of boilerplate delegation.

Answer 2

This is another solution:

XmlWriterSettings settings = new XmlWriterSettings();
//If you wish Encoding
settings.Encoding = Encoding.GetEncoding("ISO-8859-1");

using (XmlWriter xmlWriter = XmlWriter.Create(tempFilePath, settings))
{
     var ns = new XmlSerializerNamespaces();
     ns.Add("", "http://thecompany.com");
     XmlSerializer s = new XmlSerializer(YOUROBJECT.GetType(), "http://thecompany.com");    
     s.Serialize(xmlWriter, YOUROBJECT, ns);

}

Answer 3

I sometimes use RegEx or XML Linq

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Text.RegularExpressions;
using System.Xml;
using System.Xml.Linq;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            string input =
                "<q1:InventoryFeed xmlns:q1=\"http://thecompany.com/\">\n" +
                    "<q1:InventoryHeader>\n" +
                        "<q1:version>1.4</q1:version>\n" +
                    "</q1:InventoryHeader>\n" +
                    "<q1:inventory>v" +
                        "<q1:sku>WMSkuCap0180</q1:sku>\n" +
                        "<q1:quantity>\n" +
                            "<q1:unit>EACH</q1:unit>\n" +
                            "<q1:amount>3</q1:amount>\n" +
                        "</q1:quantity>\n" +
                        "<q1:fulfillmentLagTime>1</q1:fulfillmentLagTime>\n" +
                    "</q1:inventory>\n" +
                "</q1:InventoryFeed>\n";

            string pattern1 = @"<[^/][^:]+:";
            string output = Regex.Replace(input, pattern1, "<");
            string pattern2 = @"</[^:]+:";
            output = Regex.Replace(output, pattern2, "</");

            //using xml linq
            XElement element = XElement.Parse(input);
            foreach (var node in element.DescendantNodesAndSelf())
            {
                if (node.NodeType == XmlNodeType.Element)
                {
                    ((XElement)node).Name = ((XElement)node).Name.LocalName;
                }
            }
        }
    }
}
