TidyMarkup

Since Camel 2.0

TidyMarkup is a Data Format that uses the TagSoup to tidy up HTML. It can be used to parse ugly HTML and return it as pretty wellformed HTML.

Camel eats our own -dog food- soap

We had some issues in our pdf Manual where we had some strange symbols. So Jonathan used this data format to tidy up the wiki html pages that are used as base for rendering the pdf manuals. And then the mysterious symbols vanished.

TidyMarkup only supports the unmarshal operation as we really don’t want to turn well formed HTML into ugly HTML.

TidyMarkup Options

The TidyMarkup dataformat supports 3 options, which are listed below.

Name Default Java Type Description

dataObjectType

org.w3c.dom.Node

String

What data type to unmarshal as, can either be org.w3c.dom.Node or java.lang.String. Is by default org.w3c.dom.Node

omitXmlDeclaration

false

Boolean

When returning a String, do we omit the XML declaration in the top.

contentTypeHeader

false

Boolean

Whether the data format should set the Content-Type header with the type from the data format if the data format is capable of doing so. For example application/xml for data formats marshalling to XML, or application/json for data formats marshalling to JSon etc.

Spring Boot Auto-Configuration

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

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

The component supports 4 options, which are listed below.

Name Description Default Type

camel.dataformat.tidymarkup.content-type-header

Whether the data format should set the Content-Type header with the type from the data format if the data format is capable of doing so. For example application/xml for data formats marshalling to XML, or application/json for data formats marshalling to JSon etc.

Java DSL Example

An example where the consumer provides some HTML

from("file://site/inbox").unmarshal().tidyMarkup().to("file://site/blogs");

Spring XML Example

The following example shows how to use TidyMarkup to unmarshal using Spring

<camelContext id="camel" xmlns="http://camel.apache.org/schema/spring">
  <route>
    <from uri="file://site/inbox"/>
    <unmarshal>
      <tidyMarkup/>
    </unmarshal>
    <to uri="file://site/blogs"/>
  </route>
</camelContext>

Dependencies

To use TidyMarkup in your camel routes you need to add the a dependency on camel-tagsoup which implements this data format.

If you use maven you could just add the following to your pom.xml, substituting the version number for the latest & greatest release (see the download page for the latest versions).

<dependency>
  <groupId>org.apache.camel</groupId>
  <artifactId>camel-tagsoup</artifactId>
  <version>x.x.x</version>
</dependency>
