4.5.9.10. XSL Transformation

Note

These preference settings only apply to CityGML exports.

Like with CityGML imports, you can apply XSL transformations during the export process to change the resulting CityGML output data. Simply check the Apply XSLT stylesheets option and point to an XSLT stylesheet in your local file system using the Browse button. The stylesheet will be automatically considered by the export process to transform the CityGML data before it is written to a file.

Fig. 4.49 Export preferences – XSL transformation.

By clicking the + and - buttons, more than one XSLT stylesheet can be provided to the exporter. The stylesheets are applied in the given order, with the output of a stylesheet being the input for its direct successor. The Importer/Exporter is shipped with example XSLT stylesheets in the folder templates/XSLTransformations of the installation directory.

Note

• To be able to handle arbitrarily large exports, the export process reads single top-level features from the database, which are then written to the target file. Thus, each XSLT stylesheet will just work on individual top-level features but not on the entire file.
• The output of each XSLT stylesheet must again be a valid CityGML structure.
• Only stylesheets written in the XSLT language version 1.0 are supported.
