+<p>You can also create compound predicates using boolean operators such as
<tt>and, or, not</tt> and many others.</p>
+
+<p>Currently this feature is only available in the Java-based DSLs, but not in
the Spring nor Blueprint DSLs.</p>
+
+<p>Using the <a shape="rect" class="external-link"
href="http://camel.apache.org/maven/current/camel-core/apidocs/org/apache/camel/builder/PredicateBuilder.html";><tt>PredicateBuilder</tt></a>
class, you can combine predicates <b>from different Expression Languages</b>
based on logical operators and comparison operators:</p>
+
+<ul><li><tt>not</tt>, <tt>and</tt>, <tt>or</tt></li><li><tt>isNull</tt>,
<tt>isNotNull</tt></li><li><tt>isEqualTo</tt>, <tt>isGreaterThan</tt>,
<tt>isLessThan</tt></li><li><tt>startsWith</tt>,
<tt>endsWith</tt></li><li><tt>in</tt> ("any of X predicates stands
true")</li></ul>
+
+
+<p>Additionally, with <tt>PredicateBuilder</tt> you can create Regular
Expressions and use them as predicates, applying them to the result of an
expression, e.g. <tt>PredicateBuilder.regex(header("foo"), "\d{4}")</tt>
applies the regular expression to the header = foo.</p>
+
+<p>Combining different Expression Languages is also possible, e.g.:</p>
