如何从XML使用C＃删除所有命名空间？ [英] How to remove all namespaces from XML with C#?

问题描述

我要寻找清洁，优雅和智能解决方案，从所有XML元素删除namespacees？如何将功能做到这一点的样子？

I am looking for the clean, elegant and smart solution to remove namespacees from all XML elements? How would function to do that look like?

定义接口：

public interface IXMLUtils
{
        string RemoveAllNamespaces(string xmlDocument);
}

XML示例要从中删除NS：

Sample XML to remove NS from:

<?xml version="1.0" encoding="utf-16"?>
<ArrayOfInserts xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <insert>
    <offer xmlns="http://schema.peters.com/doc_353/1/Types">0174587</offer>
    <type2 xmlns="http://schema.peters.com/doc_353/1/Types">014717</type2>
    <supplier xmlns="http://schema.peters.com/doc_353/1/Types">019172</supplier>
    <id_frame xmlns="http://schema.peters.com/doc_353/1/Types" />
    <type3 xmlns="http://schema.peters.com/doc_353/1/Types">
      <type2 />
      <main>false</main>
    </type3>
    <status xmlns="http://schema.peters.com/doc_353/1/Types">Some state</status>
  </insert>
</ArrayOfInserts>

在我们称之为RemoveAllNamespaces（xmlWithLotOfNs），我们应该：

After we call RemoveAllNamespaces(xmlWithLotOfNs), we should get:

  <?xml version="1.0" encoding="utf-16"?>
    <ArrayOfInserts>
      <insert>
        <offer >0174587</offer>
        <type2 >014717</type2>
        <supplier >019172</supplier>
        <id_frame  />
        <type3 >
          <type2 />
          <main>false</main>
        </type3>
        <status >Some state</status>
      </insert>
    </ArrayOfInserts>

preffered的解决方案语言是.NET 3.5 SP1 C＃。

推荐答案

嗯，这里是最后的答案。我用伟大的想法吉米（不幸的是不完整的本身）和完整的递归功能正常工作。

Well, here is the final answer. I have used great Jimmy idea (which unfortunately is not complete itself) and complete recursion function to work properly.

string RemoveAllNamespaces(string xmlDocument);

我在这里重新present最后的清洁和通用的C＃解决方案去除XML命名空间：

I represent here final clean and universal C# solution for removing XML namespaces:

//Implemented based on interface, not part of algorithm
public static string RemoveAllNamespaces(string xmlDocument)
{
    XElement xmlDocumentWithoutNs = RemoveAllNamespaces(XElement.Parse(xmlDocument));

    return xmlDocumentWithoutNs.ToString();
}

//Core recursion function
 private static XElement RemoveAllNamespaces(XElement xmlDocument)
    {
        if (!xmlDocument.HasElements)
        {
            XElement xElement = new XElement(xmlDocument.Name.LocalName);
            xElement.Value = xmlDocument.Value;

            foreach (XAttribute attribute in xmlDocument.Attributes())
                xElement.Add(attribute);

            return xElement;
        }
        return new XElement(xmlDocument.Name.LocalName, xmlDocument.Elements().Select(el => RemoveAllNamespaces(el)));
    }

它的工作100％，但我没有测试过很多，因此它可能不包括一些特殊情况下...但它是很好的基础开始。

It's working 100%, but I have not tested it much so it may not cover some special cases ... But it is good base to start.
