-<h2 id="BookInOnePage-SimpleExpressionLanguage">Simple Expression
Language</h2><p>The Simple Expression Language was a really simple language
when it was created, but has since grown more powerful. It is primarily
intended for being a really small and simple language for evaluating <a
shape="rect" href="expression.html">Expression</a>s and <a shape="rect"
href="predicate.html">Predicate</a>s without requiring any new dependencies or
knowledge of <a shape="rect" href="xpath.html">XPath</a>; so it is ideal for
testing in camel-core. The idea was to cover 95% of the common use cases when
you need a little bit of expression based script in your Camel
routes.</p><p>However for much more complex use cases you are generally
recommended to choose a more expressive and powerful language such
as:</p><ul><li><a shape="rect" href="spel.html">SpEL</a></li><li><a

shape="rect" href="ognl.html">OGNL</a></li><li>one of the supported <a
shape="rect" href="scripting-languages.html">Scripting
Languages</a></li></ul><p>The simple language uses <code>${body</code>}
placeholders for complex expressions where the expression contains constant
literals. The ${ } placeholders can be omitted if the expression is only the
token itself.</p><div class="confluence-information-macro

class="confluence-information-macro-body"><p>The <a shape="rect"
href="simple.html">Simple</a> language have been improved from Camel 2.9
onwards to use a better syntax parser, which can do index precise error
messages, so you know exactly what is wrong and where the problem is. For
example if you have made a typo in one of the operators, then previously the
parser would not be able to detect this, and cause the evaluation to be true.
There are a few changes in the syntax which are no longer backwards compatible.
When using <a shape="rect" href="simple.html">Simple</a> language as a <a
shape="rect" href="predicate.html">Predicate</a> then the literal text
<strong>must</strong> be enclosed in either si
ngle or double quotes. For example: <code>"${body} == 'Camel'"</code>. Notice
how we have single quotes around the literal. The old style of using
<code>"body"</code> and <code>"header.foo"</code> to refer to the message body
and header is @deprecated, and it is encouraged to always use ${ } tokens for
the built-in functions.<br clear="none"> The range operator now requires the
range to be in single quote as well as shown: <code>"${header.zip} between
'30000..39999'"</code>.</p></div></div><p>To get the body of the in message:
<code>"body"</code>, or <code>"in.body"</code> or
<code>"${body}"</code>.</p><p>A complex expression must use ${ } placeholders,
such as: <code>"Hello ${in.header.name} how are you?"</code>.</p><p>You can
have multiple functions in the same expression: <code>"Hello ${in.header.name}
this is ${in.header.me} speaking"</code>.<br clear="none"> However you can
<strong>not</strong> nest functions in Camel 2.8.x or older (i.e. having
another ${ } placeholder in an e
xisting, is not allowed).<br clear="none"> From <strong>Camel 2.9</strong>
onwards you can nest functions.</p><h3

Language</h2><p>The Simple Expression Language was a really simple language
when it was created, but has since grown more powerful. It is primarily
intended for being a really small and simple language for evaluating <a

href="predicate.html">Predicate</a>s without requiring any new dependencies or
knowledge of <a shape="rect" href="xpath.html">XPath</a>; so it is ideal for
testing in camel-core. The idea was to cover 95% of the common use cases when
you need a little bit of expression based script in your Camel
routes.</p><p>However for much more complex use cases you are generally
recommended to choose a more expressive and powerful language such
as:</p><ul><li><a shape="rect" href="spel.html">SpEL</a></li><li><a

shape="rect" href="scripting-languages.html">Scripting

placeholders for complex expressions where the expression contains constant
literals. The ${ } placeholders can be omitted if the expression is only the
token itself.</p><div class="confluence-information-macro

href="simple.html">Simple</a> language have been improved from Camel 2.9
onwards to use a better syntax parser, which can do index precise error
messages, so you know exactly what is wrong and where the problem is. For
example if you have made a typo in one of the operators, then previously the
parser would not be able to detect this, and cause the evaluation to be true.
There are a few changes in the syntax which are no longer backwards compatible.
When using <a shape="rect" href="simple.html">Simple</a> language as a <a

how we have single quotes around the literal. The old style of using
<code>"body"</code> and <code>"header.foo"</code> to refer to the message body
and header is @deprecated, and it is encouraged to always use ${ } tokens for
the built-in functions.<br clear="none"> The range operator now requires the
range to be in single quote as well as shown: <code>"${header.zip} between
'30000..39999'"</code>.</p></div></div><p>To get the body of the in message:

have multiple functions in the same expression: <code>"Hello ${in.header.name}
this is ${in.header.me} speaking"</code>.<br clear="none"> However you can
<strong>not</strong> nest functions in Camel 2.8.x or older (i.e. having
another ${ } placeholder in an e
