我正在用 C# 创建一个轻量级编辑器,并且想知道将字符串转换为格式良好的 XML 字符串的最佳方法.我希望 C# 库中有一个公共方法,例如public bool FormatAsXml(string text, out string formattedXmlText)",但它不可能那么容易,不是吗?
I am creating a lightweight editor in C# and would like to know the best method for converting a string into a nicely formatted XML string. I would hope that there's a public method in the C# library like "public bool FormatAsXml(string text, out string formattedXmlText)", but it couldn't be that easy, could it?
非常具体地说,SomeMethod"方法必须是什么才能产生下面的输出?
Very specifically, what would the method "SomeMethod" have to be that would produce the output below?
string unformattedXml;
string formattedXml;
unformattedXml = "<?xml version="1.0"?><book><author>Lewis, C.S.</author><title>The Four Loves</title></book>"
formattedXml = SomeMethod(unformattedXml);
Console.WriteLine(formattedXml);
输出:
<?xml version="1.0"?>
<book id="123">
<author>Lewis, C.S.</author>
<title>The Four Loves</title>
</book>
string unformattedXml = "<?xml version="1.0"?><book><author>Lewis, C.S.</author><title>The Four Loves</title></book>";
string formattedXml = XElement.Parse(unformattedXml).ToString();
Console.WriteLine(formattedXml);
输出:
<book>
<author>Lewis, C.S.</author>
<title>The Four Loves</title>
</book>
Xml 声明不是由 ToString() 输出,而是由 Save() 输出...
The Xml Declaration isn't output by ToString(), but it is by Save() ...
XElement.Parse(unformattedXml).Save(@"C:doc.xml");
Console.WriteLine(File.ReadAllText(@"C:doc.xml"));
输出:
<?xml version="1.0" encoding="utf-8"?>
<book>
<author>Lewis, C.S.</author>
<title>The Four Loves</title>
</book>
