Disable XML validation when using XDocument

Question

I'm parsing an XLIFF document using the XDocument class. Does XDocument perform some validation of the content which I read into it, and if so - is there any way to disable that validation?

I'm getting some weird errors if the XLIFF isn't valid XML (I don't care that it isn't, I just want to parse it).

E.g.

'.', hexadecimal value 0x00, is an invalid character. 

I'm currently reading the file like this:

string FileLocation = @"C:\XLIFF\text.xlf";
XDocument doc = XDocument.Load(FileLocation);

Thanks.

I had similar problem which was fixed by letting StreamReader to read the content.

// this line throws exception like yours
XDocument xd = XDocument.Load(@"C:\test.xml");

// works
XDocument xd = XDocument.Load(new System.IO.StreamReader(@"C:\test.xml"));

If that does not help, try to include proper encoding.

If you want to strip characters from strings that are invalid for use in XML, you can use this method:

private static string RemoveXmlInvalidCharacters(string s)
{
    return Regex.Replace(
        s,
        @"[^\u0009\u000A\u000D\u0020-\uD7FF\uE000-\uFFFD\u10000-\u10FFFF]",
        string.Empty);
}

It removes any characters that fall outside of the set of valid character values, according to the XML standard.
