XML Tokenize

Since Camel 2.14

The XML Tokenize language is a built-in language in camel-stax, which is a truly XML-aware tokenizer that can be used with the Split EIP as the conventional Tokenize to efficiently and effectively tokenize XML documents.

XML Tokenize is capable of not only recognizing XML namespaces and hierarchical structures of the document but also more efficiently tokenizing XML documents than the conventional Tokenize language.

XML Tokenizer Options

The XML Tokenize language supports 5 options, which are listed below.

Name Default Java Type Description

mode (common)

i

Enum

The extraction mode. The available extraction modes are: i - injecting the contextual namespace bindings into the extracted token (default) w - wrapping the extracted token in its ancestor context u - unwrapping the extracted token to its child content t - extracting the text content of the specified element.

Enum values:

  • i

  • w

  • u

  • t

group (common)

Integer

To group N parts together.

source (common)

String

Source to use, instead of message body. You can prefix with variable:, header:, or property: to specify kind of source. Otherwise, the source is assumed to be a variable. Use empty or null to use default source, which is the message body.

resultType (common)

String

Sets the class of the result type (type from output).

trim (advanced)

true

Boolean

Whether to trim the value to remove leading and trailing whitespaces and line breaks.

Example

See Split EIP, which has examples using the XML Tokenize language.

Spring Boot Auto-Configuration

When using xtokenize with Spring Boot make sure to use the following Maven dependency to have support for auto configuration:

<dependency>
  <groupId>org.apache.camel.springboot</groupId>
  <artifactId>camel-stax-starter</artifactId>
  <version>x.x.x</version>
  <!-- use the same version as your Camel core version -->
</dependency>

The component supports 8 options, which are listed below.

Name Description Default Type

camel.component.stax.autowired-enabled

Whether autowiring is enabled. This is used for automatic autowiring options (the option must be marked as autowired) by looking up in the registry to find if there is a single instance of matching type, which then gets configured on the component. This can be used for automatic configuring JDBC data sources, JMS connection factories, AWS Clients, etc.

true

Boolean

camel.component.stax.enabled

Whether to enable auto configuration of the stax component. This is enabled by default.

Boolean

camel.component.stax.lazy-start-producer

Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel’s routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing.

false

Boolean

camel.language.xtokenize.enabled

Whether to enable auto configuration of the xtokenize language. This is enabled by default.

Boolean

camel.language.xtokenize.mode

The extraction mode. The available extraction modes are: i - injecting the contextual namespace bindings into the extracted token (default) w - wrapping the extracted token in its ancestor context u - unwrapping the extracted token to its child content t - extracting the text content of the specified element.

i

String

camel.language.xtokenize.namespace

Injects the XML Namespaces of prefix - uri mappings.

List

camel.language.xtokenize.source

Source to use, instead of message body. You can prefix with variable:, header:, or property: to specify kind of source. Otherwise, the source is assumed to be a variable. Use empty or null to use default source, which is the message body.

String

camel.language.xtokenize.trim

Whether to trim the value to remove leading and trailing whitespaces and line breaks.

true

Boolean
