FME Transformers: 2025.2 BETA
The XSLTProcessor uses an XSL (eXtensible Stylesheet Language) stylesheet to convert an XML document.
Note It is assumed that you have created (or have access to) an XSLT stylesheet that is applicable to your XML input source.
Optional Input Port
This transformer has two modes, depending on whether a connector is attached to the Input port or not:
- Input-driven: When input features are connected, the transformer runs once for each feature it receives in the Input port.
- Run Once: When no input features are connected, the transformer runs one time and outputs a single new feature.
Configuration
Input Ports
Input (Optional)
This transformer accepts any feature.
Output Ports
Transformed
Each transformed document is output via this port. The transformed document may be either embedded in an attribute or written to a file.
Skipped
These features did not transform due to errors (for example, an incorrect file path).
Parameters
XML Source
|
XML Source Type, XML File, XML Attribute |
The XML source type is either an XML file or a feature attribute whose value is the entire XML document. |
Configuration
|
Configuration Type, File, Embedded, Attribute |
The stylesheet document is either an XML file, embedded in the transformer, or in a feature attribute whose value is the entire stylesheet document |
Results
|
Results Type, Attribute, File |
The results from applying the stylesheet to the input document can be either stored in an attribute value or written to a file. |
Editing Transformer Parameters
Transformer parameters can be set by directly entering values, using expressions, or referencing other elements in the workspace such as attribute values or user parameters. Various editors and context menus are available to assist. To see what is available, click 
beside the applicable parameter.
How to Set Parameter Values
Defining Values
There are several ways to define a value for use in a Transformer. The simplest is to simply type in a value or string, which can include functions of various types such as attribute references, math and string functions, and workspace parameters.
Using the Text Editor
The Text Editor provides a convenient way to construct text strings (including regular expressions) from various data sources, such as attributes, parameters, and constants, where the result is used directly inside a parameter.
Using the Arithmetic Editor
The Arithmetic Editor provides a convenient way to construct math expressions from various data sources, such as attributes, parameters, and feature functions, where the result is used directly inside a parameter.
Conditional Values
Set values depending on one or more test conditions that either pass or fail.
Parameter Condition Definition Dialog
Content
Expressions and strings can include a number of functions, characters, parameters, and more.
When setting values - whether entered directly in a parameter or constructed using one of the editors - strings and expressions containing String, Math, Date/Time or FME Feature Functions will have those functions evaluated. Therefore, the names of these functions (in the form @<function_name>) should not be used as literal string values.
Content Types
| These functions manipulate and format strings. | |
|
Special Characters |
A set of control characters is available in the Text Editor. |
| Math functions are available in both editors. | |
| Date/Time Functions | Date and time functions are available in the Text Editor. |
| These operators are available in the Arithmetic Editor. | |
| These return primarily feature-specific values. | |
| FME and workspace-specific parameters may be used. | |
| Creating and Modifying User Parameters | Create your own editable parameters. |
Dialog Options - Tables
Table Tools
Transformers with table-style parameters have additional tools for populating and manipulating values.
|
Row Reordering
|
Enabled once you have clicked on a row item. Choices include:
|
|
Cut, Copy, and Paste
|
Enabled once you have clicked on a row item. Choices include:
Cut, copy, and paste may be used within a transformer, or between transformers. |
|
Filter
|
Start typing a string, and the matrix will only display rows matching those characters. Searches all columns. This only affects the display of attributes within the transformer - it does not alter which attributes are output. |
|
Import
|
Import populates the table with a set of new attributes read from a dataset. Specific application varies between transformers. |
|
Reset/Refresh
|
Generally resets the table to its initial state, and may provide additional options to remove invalid entries. Behavior varies between transformers. |
Note: Not all tools are available in all transformers.
For more information, see Transformer Parameter Menu Options.
