Special Characters and XML Strings

http://www.devx.com/tips/Tip/14068

XML has a special set of characters that cannot be used in normal XML strings. These characters are:

1. & - &
2. < - &lt;
3. > - &gt;
4. " - &quot;
5. ' - &#39;

For example, the following XML string is invalid:

 <Organization>IBM & Microsoft</Organization>

Whereas the following is valid XML:

 <Organization>IBM &amp; Microsoft</Organization>

—Note that we have replaced '&' with '&amp;' in the second XML string which makes it valid.
