`--option` argument.
NOTE: The transform message with dataformat is limited as some dataformat
requires configuring complex options that cannot be set from command line.
+== Transforming routes DSL
+
+Camel offers different DSLs, such as Java, XML, YAML, and more. Many graphical
editors and code generators use XML and YAML Camel DSL, therefore, for some use
cases it may be required to use one DSL or the other.
+The `camel transform route` command can be used to transform a YAML route into
an XML and vice versa, the command takes a list of files as input and
transforms the DSL.
+
+For example, given the following YAML content, in a file named route.yaml
+
+[source:yaml]
+----
+- route:
+ id: route-b785
+ nodePrefixId: route-14b
+ from:
+ id: from-959e
+ uri: direct
+ parameters:
+ name: start
+ steps:
+ - choice:
+ id: choice-52fe
+ when:
+ - id: when-b126
+ expression:
+ simple:
+ id: simple-576d
+ expression: ${header.foo} == 'bar'
+ steps:
+ - to:
+ id: to-65f9
+ uri: jms
+ parameters:
+ destinationName: queue
+ otherwise:
+ id: otherwise-c07f
+ steps:
+ - to:
+ id: to-dc76
+ uri: log
+ parameters:
+ loggerName: default
+----
+
+The following command
+
+[source:bash]
+----
+camel transform route --format=xml /path/to/route.yaml
+----
+
+Automatically transform the route in XML DSL (Camel XML IO DSL)
+
+[source:xml]
+----
+<camel>
+ <route id="route-b785" nodePrefixId="route-14b">
+ <from id="from-959e" uri="direct:start"/>
+ <choice id="choice-52fe">
+ <when id="when-b126">
+ <simple>${header.foo} == 'bar'</simple>
+ <to id="to-65f9" uri="jms:queue"/>
+ </when>
+ <otherwise id="otherwise-c07f">
+ <to id="to-dc76" uri="log:default"/>
+ </otherwise>
+ </choice>
+ </route>
+</camel>
+----
+
+TIP: If all the input files have the same extension and are written with the
same DSL, for example, `.yaml`, the transformation will default to the XML DSL
and vice versa.
