h2. Validation Component

The Validation component performs XML validation of the message body using the JAXP Validation API and based on any of the supported XML schema languages, which defaults to [XML Schema|http://www.w3.org/XML/Schema] 

Note that the [Jing] component also supports the following useful schema languages:
 
* [RelaxNG Compact Syntax|http://relaxng.org/compact-tutorial-20030326.html]
* [RelaxNG XML Syntax|http://relaxng.org/]

The [MSV] component also supports [RelaxNG XML Syntax|http://relaxng.org/].

h3. URI format

{code}
validator:someLocalOrRemoteResource
{code}

Where *someLocalOrRemoteResource* is some URL to a local resource on the classpath or a full URL to a remote resource or resource on the file system which contains the XSD to validate against. For example:

* {{msv:org/foo/bar.xsd}}
* {{msv:file:../foo/bar.xsd}}
* {{msv:http://acme.com/cheese.xsd}}
* {{validator:com/mypackage/myschema.xsd}}

Maven users will need to add the following dependency to their {{pom.xml}} for this component when using *Camel 2.8* or older:
{code:xml}
<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-spring</artifactId>
    <version>x.x.x</version>
    <!-- use the same version as your Camel core version -->
</dependency>
{code}
From Camel 2.9 onwards the [Validation] component is provided directly in the camel-core.

h3. Options
{div:class=confluenceTableSmall}
|| Option || Default || Description ||
| {{useDom}} | {{false}} | *Camel 2.0:* Whether {{DOMSource}}/{{DOMResult}} or {{SaxSource}}/{{SaxResult}} should be used by the validator. |
| {{useSharedSchema}} | {{true}} | *Camel 2.3:* Whether the {{Schema}} instance should be shared or not. This option is introduced to work around a [JDK 1.6.x bug|http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6773084]. Xerces should not have this issue. |

h3. Example

The following [example|http://svn.apache.org/repos/asf/camel/trunk/components/camel-spring/src/test/resources/org/apache/camel/component/validator/camelContext.xml] shows how to configure a route from endpoint *direct:start* which then goes to one of two endpoints, either *mock:valid* or *mock:invalid* based on whether or not the XML matches the given schema (which is supplied on the classpath).
