格式化一个XML文件，使它在c#中看起来更好

// Format the XML text.
StringWriter string_writer = new StringWriter();
XmlTextWriter xml_text_writer = new XmlTextWriter(string_writer);
xml_text_writer.Formatting = Formatting.Indented;
xml_document.WriteTo(xml_text_writer);

// Display the result.
txtResult.Text = string_writer.ToString();

我试着:

internal static void IndentedNewWSDLString(string filePath)
{
    var xml = File.ReadAllText(filePath);
    XDocument doc = XDocument.Parse(xml);
    File.WriteAllText(filePath, doc.ToString());
}

它像预期的那样正常工作。

.NET 2.0忽略名称解析，并使用适当的资源处理、缩进、保留空白和自定义编码:

public static string Beautify(System.Xml.XmlDocument doc)
{
    string strRetValue = null;
    System.Text.Encoding enc = System.Text.Encoding.UTF8;
    // enc = new System.Text.UTF8Encoding(false);

    System.Xml.XmlWriterSettings xmlWriterSettings = new System.Xml.XmlWriterSettings();
    xmlWriterSettings.Encoding = enc;
    xmlWriterSettings.Indent = true;
    xmlWriterSettings.IndentChars = "    ";
    xmlWriterSettings.NewLineChars = "\r\n";
    xmlWriterSettings.NewLineHandling = System.Xml.NewLineHandling.Replace;
    //xmlWriterSettings.OmitXmlDeclaration = true;
    xmlWriterSettings.ConformanceLevel = System.Xml.ConformanceLevel.Document;


    using (System.IO.MemoryStream ms = new System.IO.MemoryStream())
    {
        using (System.Xml.XmlWriter writer = System.Xml.XmlWriter.Create(ms, xmlWriterSettings))
        {
            doc.Save(writer);
            writer.Flush();
            ms.Flush();

            writer.Close();
        } // End Using writer

        ms.Position = 0;
        using (System.IO.StreamReader sr = new System.IO.StreamReader(ms, enc))
        {
            // Extract the text from the StreamReader.
            strRetValue = sr.ReadToEnd();

            sr.Close();
        } // End Using sr

        ms.Close();
    } // End Using ms


    /*
    System.Text.StringBuilder sb = new System.Text.StringBuilder(); // Always yields UTF-16, no matter the set encoding
    using (System.Xml.XmlWriter writer = System.Xml.XmlWriter.Create(sb, settings))
    {
        doc.Save(writer);
        writer.Close();
    } // End Using writer
    strRetValue = sb.ToString();
    sb.Length = 0;
    sb = null;
    */

    xmlWriterSettings = null;
    return strRetValue;
} // End Function Beautify

用法:

System.Xml.XmlDocument xmlDoc = new System.Xml.XmlDocument();
xmlDoc.XmlResolver = null;
xmlDoc.PreserveWhitespace = true;
xmlDoc.Load("C:\Test.svg");
string SVG = Beautify(xmlDoc);

来自kristopherjohnson的这条就好多了:

It doesn't require an XML document header either. Has clearer exceptions Adds extra behaviour options: OmitXmlDeclaration = true, NewLineOnAttributes = true Less lines of code static string PrettyXml(string xml) { var stringBuilder = new StringBuilder(); var element = XElement.Parse(xml); var settings = new XmlWriterSettings(); settings.OmitXmlDeclaration = true; settings.Indent = true; settings.NewLineOnAttributes = true; using (var xmlWriter = XmlWriter.Create(stringBuilder, settings)) { element.Save(xmlWriter); } return stringBuilder.ToString(); }

你必须以某种方式解析内容。我发现使用LINQ是最简单的方法。同样，这完全取决于您的具体场景。下面是一个使用LINQ格式化输入XML字符串的示例。

string FormatXml(string xml)
{
     try
     {
         XDocument doc = XDocument.Parse(xml);
         return doc.ToString();
     }
     catch (Exception)
     {
         // Handle and throw if fatal exception here; don't just ignore them
         return xml;
     }
 }

[为简洁起见，省略使用语句]
