FME Transformers: 2024.1
FME Transformers: 2024.1
XMLNamespaceDeclarer
Declares missing namespaces in XML documents by matching prefixes from another sample XML file whose namespaces are fully declared.
Example
<root>
<f:element1>
<f:element2> some text </f:element2>
<f:element3> some text </f:element3>
</f:element1>
</root>
and the sample XML file:
<root>
<f:element1 xmlns:f="http://www.w3schools.com/example">
<f:element2 xmlns:f=" http://www.w3schools.com/example"> some text </f:element2>
<f:element3 xmlns:f=" http://www.w3schools.com/example"> some text </f:element3>
</f:element1>
</root>
the output will look like this:
<root>
<f:element1 xmlns:f="http://www.w3schools.com/example">
<f:element2> some text </f:element2>
<f:element3> some text </f:element3>
</f:element1>
</root>
Configuration
Input Ports
Input
Input features that contain the information of the XML documents.
Output Ports
Passed
If the XML namespaces of the input document are fixed and well-formed, it will be output through this port.
INVALID
If a feature does not have a well-formed XML document, it will be output through this port.
Parameters
XML Input
XML Input |
Select from the pull-down list to enable the selection's corresponding parameter:
|
Sample XML File
Sample XML File For Missing Namespaces |
The sample XML file that will be used as a reference for declaring missing namespaces in the XML input documents. If the sample file has more than one namespace with the same prefix but different URI, then the first one will always be used. |
XML Output
XML Output Type |
Attribute to contain XML output/XML Output File: The XML features that have been successfully processed can be output to a feature attribute by specifying an attribute name in the Attribute to contain XML Output, or to a file by specifying the path to the file in XML Output File parameter. Error and Warning List Name: Features with at least one warning or error will be output through the Failed port with a new list attribute added to the features. If the default _xml_error is the list name, the elements of the list attribute contain the following:
Note List attributes are not accessible from the output schema in FME Workbench unless they are first processed using a transformer that operates on them, such as ListExploder or ListConcatenator. Alternatively, AttributeExposer can be used.

Pretty Printing
Pretty Print |
The parameter specifies if the XML output should be pretty-printed with indentation. |
Indent Size |
This parameter specifies the size of a single indentation. |
Replace Tabs with Spaces |
By default, the tab character is used for pretty printing, use this parameter to replace the tabs with spaces. |
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.
