Escape them to "&lt;" and "&gt;" (excluding the surrounding quotes.

">" is ususally safe even unescaped in most contexts.

Sometimes it becomes necessary to escape the quotes and the apostrophe
characters -- accordingly -- with "&quot;" and "&apos;"

Another character to escape almost always is the ampersand character
itself -- this is escaped as "&amp;"

Thanks.

Also, this is a .NET XML newsgroup, so presumably you're using .NET to
read/write these strings?
If so, XmlTextReader/Writer and XmlDocument both escape the contents
automatically, so you generally don't have to worry about it.

Do you want to create an XML document that contains those characters? As
already pointed out if you use Xml(Text)Writer then escaping is done
automatically if you use the proper API calls (e.g. WriteElementString).

It is not clear whether you want to create such a document or whether
you want to parse an existing document. Parsing markup with unescaped
'<' or '&' content with an XML parser will give you a parse error as the
markup is not well-formed XML.
