我有一个这样的XML字符串:
<?xml version='1.0'?><response><error code='1'> Success</error></response>
一个元素和另一个元素之间没有行，因此很难阅读。我想要一个函数格式化上面的字符串:
<?xml version='1.0'?>
<response>
<error code='1'> Success</error>
</response>
不需要自己手动编写格式函数，是否有任何。net库或代码片段我可以立即使用?

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(); }

对我来说，最简单的解决方法就是:
XmlDocument xmlDoc = new XmlDocument();
StringWriter sw = new StringWriter();
xmlDoc.LoadXml(rawStringXML);
xmlDoc.Save(sw);
String formattedXml = sw.ToString();
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();
嗨，你为什么不试试这个
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.PreserveWhitespace = false;
....
....
xmlDoc.Save(fileName);
PreserveWhitespace = false;该选项也可以用于XML美化器。

.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);
