Constructs features out of GeoRSS documents/URLs that are stored in a specified attribute of the input features. The features from the GeoRSS document/URL are output with the attributes from the original feature and are merged, if desired.
One feature will be output for each GeoRSS entry in the GeoRSS document.
Features whose GeoRSS attribute does not contain valid GeoRSS.
The attribute to read from.
The GeoRSS reader can be run in two modes:
- In NORMAL mode, the reader will always return a feature for every feed entry that it processes.
- In UPDATE mode, the reader will only return entry features if they are new or updated.
If this parameter is No, features whose GeoRSS attribute does not contain valid GeoRSS will be output via the InvalidGeorss port.
The specification of the optional Merge Attributes and associated prefix results in the copying of attributes from the Input feature into the constructed GeoRSS features. If a merge prefix is specified, then the string prefix is added at the start of each attribute from the original feature.
Since a GeoRSS document may contain several features, the transformer allows the sequence of GeoRSS features from a particular GeoRSS document to be numbered.
Furthermore, each GeoRSS feature can also be tagged by a unique sequence number that identifies it as coming from the same GeoRSS document; the optional Feature Identifier parameter can be used to specify the name for this attribute.
The value of this parameter is only used if the reader is accessing a dataset which is a URL. The value should be a space-separated list of space-separated name-value pairs. The name value pairs will be added to the dataset URL. A value must be provided for each parameter name. An empty string ( ““ ) can be used to provide an empty parameter value.
Note: For access outside of your network using a proxy server, use the Network tools in FME Options. From the Workbench menu, select Tools > FME Options > Network. For more information, see "Network" in the FME Workbench Help.
Specifies the age in days at which entries will be deleted from a feed’s database. When the reader is run in UPDATE mode, the reader will delete any entries from the database for this feed which are older than the specified value. This ensures the feed database does not become arbitrarily large. If the value of this directive is not specified, or is 0, no entries will be deleted.
Specifies the filesystem folder which contains the databases that store information about the feeds that the GeoRSS reader has processed. This parameter is only read from the transformer if the reader is running in UPDATE mode. If no value is set, the FME temp folder will be used.
This transformer works in conjunction with the GeoRSS Reader/Writer. For technical information on the GeoRSS Reader/Writer, choose FME Readers and Writers Reference from the Workbench help menu.
Editing Transformer Parameters
Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, click beside the applicable parameter. For more information, see Transformer Parameter Menu Options.
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. There are a number of tools and shortcuts that can assist in constructing values, generally available from the drop-down context menu adjacent to the value field.
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.
Set values depending on one or more test conditions that either pass or fail.
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.
|These functions manipulate and format strings.|
|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
Transformers with table-style parameters have additional tools for populating and manipulating values.
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.
|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 populates the table with a set of new attributes read from a dataset. Specific application varies between transformers.|
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.
