I have sample XML file:
<?xml version="1.0" encoding="UTF-8"?><root><name id="show_file.php?fid=120983&action=download" /></root>
I use simple C# console application to dump the content of this XML:
static void Main(string[] args)
{
var xmlPath = @"c:\test.xml";
var xml = XElement.Load(xmlPath);
Console.WriteLine(xml.ToString());
}However, an error occurs:
An unhandled exception of type 'System.Xml.XmlException' occurred in System.Xml.dllAdditional information: '=' is an unexpected token. The expected token is ';'
The error points to "=" sign here "&action=". I looked up the stack trace:
System.Xml.XmlException was unhandledHResult=-2146232000
Message='=' is an unexpected token. The expected token is ';'. Line 67, position 93.
Source=System.Xml
LineNumber=67
LinePosition=93
SourceUri=""

The point of interest is System.Xml.XmlTextReaderImpl.HandleEntityReference(Boolean isInAttributeValue, EntityExpandType expandType, Int32& charRefEndPos). As I understand, Xml searches for entity tokens in attribute value. But is it mandatory? I think I can store in attribute value ANY characters and their combinations as far as I use parenthesis. Am I right?
There is no knowledge that is not power.
