XElement.Parse和属性中的特殊字符

Question

I have a string containing xml eg:

<Person Name="Molly O&apos;Mahony" />

I want to convert this to an XElement, maintaining the & apos ; and not converting it to '

using

XElement.Parse(string);

creates the element <Person Name="Molly O'Mahony" /> Is this possible?

Answer 1

Here we go:

var txt = "<Person Name=\"Molly O&apos;Mahony\" />";

var e  = XElement.Parse(txt, LoadOptions.SetLineInfo);
var li = (IXmlLineInfo) e.Attribute("Name");

// li.LinePosition points to first char of the attribute: Name="Molly O&apos;Mahony"
//                                                        ^

var start = txt.IndexOf('"', li.LinePosition) + 1;  
var end   = txt.IndexOf('"', start);
var len   = end - start;

var attr  = txt.Substring(start, len); // Molly O&apos;Mahony

You might need to adjust the code to make it work with multi-line text.
