XSLT component

The XLST component is able to apply transformations on exchanges that carry XML content. It supports XSLT 2.0 and XPath 2.0.

It takes an an (HTTP) URL to a XLST file, which is used to transform the XML content. The XSLT file may include absolute links to other files.

If you use MapForce to create your XSLT be aware that not all functions are compatible with our XSLT component.

Configuration​

This component can not be used as the first component in a flow, since it expects to consume XML exchanges.

The XSLT component has the following configuration options:

PropertyDescription
URLPath to XSLT file that defines the transformation
XSLT FileA xslt file that has been uploaded to be used with the flow.

Remarks​

  • You can't use both options in the XSLT component. You can only use one or the other.
  • Using the XSLT File has an advantage on the URL. When using the XSLT File property your xslt file are also versioned with your flow versions. That isn't the case when you use the URL!
  • The XSLT component has to be configured with an (HTTP) URL

It also has a Compile XSLT button, that validates whether Dovetail can access the XSLT file and that the XSLT file is valid.

Runtime behavior​

The XSLT component compiles the XSLT during installation and caches it. Changes to a XSLT file will not take effect unless an integration flow is re=depolyed/re-installed.

Special care with the XSLT​

Any files referenced inside the XSLT must have an absolute http url that can be reached by Dovetail ESB, otherwise it will not be able to find these resources.

For example:


<!-- DON'T DO THIS -->
<xsl:with-param name="file" select="'./codeconversion.xml'" as="item()"/>

<!-- DO THIS INSTEAD! -->
<xsl:with-param name="file" select="'http://dovetail.example.local/xslt/codeconversion.xml'" as="item()"/>

Unsupported XSLT​

Not all (Mapforce) XSLT functions or constructors are supported in this component. A hint that you are using an unsupported fucntion is an undefined message when you try to compile the XSLT in its settings.

Our XSLT component uses the SaxParser library.

Known unsupported functions are:

  • auto-number
  • xslx-to-date

Known unsupported constructors are:

  • xs:int, use xs:integer instead
