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>

Parameters

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:

Elements of List Attribute	Description
_xml_error{}.type	WARNING, ERROR or FATAL ERROR
_xml_error{}.file	the file where the warning or error occurs
_xml_error{}.line	the line where the warning or error occurs
_xml_error{}.col	the column where the warning or error occurs
_xml_error{}.desc	the details about the warning or error

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.

Text Editor

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.

Arithmetic Editor

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

String Functions	These functions manipulate and format strings.
Special Characters	A set of control characters is available in the Text Editor.
Math Functions	Math functions are available in both editors.
Date/Time Functions	Date and time functions are available in the Text Editor.
Math Operators	These operators are available in the Arithmetic Editor.
FME Feature Functions	These return primarily feature-specific values.
FME Parameters	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:

Add a row
Remove a row
Move current row up one
Move current row down one
Move current row to top
Move current row to bottom

Cut, Copy, and Paste

Enabled once you have clicked on a row item. Choices include:

Cut a row - delete and copy to clipboard
Copy a row to the clipboard
Paste a row from the clipboard

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.
