格式化XML字符串列印XML字符串 [英] Format XML String to Print Friendly XML String

问题描述

我有一个XML字符串这样：

I have an XML string as such:

<?xml version='1.0'?><response><error code='1'> Success</error></response>

有一个元件和另一个，从而之间没有线是很难看的。我想要格式化上面的字符串的函数：

There are no lines between one element and another, and thus is very difficult to read. I want a function that formats the above string:

<?xml version='1.0'?>
<response>
<error code='1'> Success</error>
</response>

没有求助于手动编写格式函数自己，有任何.NET库或code片段，我可以随便用？

Without resorting to manually write the format function myself, is there any .Net library or code snippet that I can use offhand?

推荐答案

使用XmlTextWriter的...

Use XmlTextWriter...

public static String PrintXML(String XML)
{
String Result = "";

MemoryStream mStream = new MemoryStream();
XmlTextWriter writer = new XmlTextWriter(mStream, Encoding.Unicode);
XmlDocument document   = new XmlDocument();

try
{
	// Load the XmlDocument with the XML.
	document.LoadXml(XML);

	writer.Formatting = Formatting.Indented;

	// Write the XML into a formatting XmlTextWriter
	document.WriteContentTo(writer);
	writer.Flush();
	mStream.Flush();

	// Have to rewind the MemoryStream in order to read
	// its contents.
	mStream.Position = 0;

	// Read MemoryStream contents into a StreamReader.
	StreamReader sReader = new StreamReader(mStream);

	// Extract the text from the StreamReader.
	String FormattedXML = sReader.ReadToEnd();

	Result = FormattedXML;
}
catch (XmlException)
{
}

mStream.Close();
writer.Close();

return Result;
}
