FME Transformers: 2024.1
GeoRSSFeatureComposer
Constructs GeoRSS documents from the input features and stores them in the specified attribute for the features that are output by the GeoRSS port. The constructed GeoRSS document will be created according to the specified Geometry Format and Output Format, in the character set specified by the Output Character Set parameter.
Configuration
Input Ports
Feed
For any given GeoRSS document, the metadata for the feed.
Entry
The entry features from the input GeoRSS document/feed.
Output Ports
Georss
The features containing the GeoRSS document in the attribute specified by the GeoRSS Attribute parameter.
Parameters
General
Flush Attribute |
The GeoRSS document that is being constructed accumulates features until the value specified for the feature Flush Attribute. When this occurs, the newly received input feature is not part of the flushed document, but rather is part of the next document to be constructed. |
Output Format |
Choose the format of the XML feed that the GeoRSS writer will produce:
|
Geometry Format |
Choose the format of the output feed’s geometry extensions: GML, W3C, or Simple. |
Escape HTML Content |
This parameter determines how the writer handles HTML content. Select Yes to ensure that the writer will escape HTML content before outputting it. Select No to ensure that the writer will output the content unchanged. |
Output Character Set |
The character set encoding in which the output XML feed should be written. If no character set is specified, the feed will be written in the UTF-8 character set. If an invalid character set is specified, the translation will fail. |
Output Attribute Name
Composed GeoRSS |
Name the attribute to contain the GeoRSS document. |
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.
