angle bracket in xml value

Question

How can I put an angle bracket ("<") in my xml attribute?

I'm trying to store an SQL query, but this seems to be illegal.

<add key="query" value="SELECT DISTINCT index FROM table WHERE langCode <> 'FR'"/>

Answer 1

Use < and > instead of < and >:

<add key="query" value="SELECT DISTINCT index FROM table WHERE langCode &lt;&gt; 'FR'"/>
