" and ' is not XML-ified

[Johnny Ljunggren]

Hello all

Just noticed that a testprogram I've made creates a non-conforming XML
file. Here's the code (C#) and output:

XmlWriterSettings settings = new XmlWriterSettings();
settings.Indent = true;
using(XmlWriter writer = XmlWriter.Create("xmltest.xml",settings))
{
// Write XML data.
writer.WriteStartElement("xmltest");
string tmp = "< & ' \"";
writer.WriteElementString("test",tmp);
writer.WriteEndElement();
writer.Flush();
}

output:
<?xml version="1.0" encoding="utf-8"?>
<xmltest>
<test>&lt; &gt; &amp; ' "</test>
</xmltest>

How come ' and " is not translated to &apos; and &quot;?

Also, I tried to manually translate ' and " but then XmlWriter will
translate the extra & and thus gives &amp;apos; etc.

Any pointers to this would be greatly appreciated.

regards
Johnny Ljunggren

The characters ' and " need to be escaped if and only if they are
supposed to occur in an attribute value that is delimited using the
same character, so name='Teal'C' is not allowed, but name="Teal'C"
is. So the content is fine, and I would suggest to not worry about
this.
