Regular Expressions

Is there support for regular expressions as a language for Expressions and
Predicates in Camel?

In the Java DSL there are also method for check if message contains some
content.
I would like to know if it is possible to use 'contains' predicate in XML
configuration - I want to check if header contains some string.

Hi

You are Welcome. Its already there but its named: regex

    /**
     * Creates a predicate which is true if this expression matches the given
     * regular expression
     * 
     * @param regex the regular expression to match
     * @return a predicate which evaluates to true if the expression matches the
     *         regex
     */
    public Predicate<E> regex(String regex) {

RE: Regular Expressions

Hi

But it could be a good idea with a regexp(pattern) predicate add to a builder, so you can do it with the fluent builders?

I actually thought there was one already.

eg to filter all kind of test users in a route:
from("activemq:orders").
filter().header("username").regexp("$.*test^").to("seda:queue:justTests")
.to("bean:processOrder");

Bean language is just OK. I will create custom bean for regex pattern
matching.

For now the easiest way to do this is just invoke a Java method as an
expression within the routing logic.

They are just helper methods for creating a regex expression for use in the DSL

I need to inspect value of the body or value of the header against regular
expression.
It will be good if routing could be made after regexp matching.

Can you tell me more about helper methods you mentioned?

Thanks

There are some helper methods in the Java DSL in ExpressionBuilder;
but we've not yet integrated it into the languages for use in XML or
in the ExpressionClause class.

Could you give an example of how you'd like to use it? Is it to use a
regex as a predicate?
