    Because XPath words and phrases can match any number of distinct elements, this operation returns a series of strings. If no element matches the expression, the operation returns an empty list. XPath expressions are also usually namespace compatible, so this operation creates namespace mappings.

    There are two ways to specify phrases, depending on where the phrase can be used. Typically, expression-based elements such as the expression converter, expression cleanup, and expression-based routers, such as their expression message separator, have expression, evaluator, and custom-evaluator defined components. For example:

    Only one expression can be created for these elements. When defining expressions for points, such as property values, you can place multiple expressions using the syntax:

    How do you validate in Mule?

    Email address validator. Regular expression validator. Check if the validator is empty.size check.There is no null validator.number checkra.

    The syntax requires that each type of expression be preceded by #[, then the evaluator is set followed by a gut (:), and the expression is executed such that it is executed. Finally, complete the expression because of ]. You can define one or more expressions as a character string. For example:

    See below is a list of available Expression Reference Evaluators.

    #[:]
        

    Additional Values

    Starting with Mule 2.2, buyers can use an asterisk to indicate that an optional property is displayed in the expression being viewed. For example, the following expression might well indicate the presence of foo and car, but bar might be optional:
