Component family

Processing / EDIFACT

 

Function

tExtractEDIField reads an input United Nations/Electronic Data Interchange For Administration, Commerce and Transport (UN/EDIFACT) message file, generates an XML according to the EDIFACT family and the EDIFACT type, and extracts data by parsing the generated XML using the XPath queries manually defined or coming from the [Repository] wizard.

Purpose

tExtractEDIField opens an input EDIFACT message file, reads the EDI structured data directly without having to write it out to a temporary file first, extracts data through XPATH queries, and finally sends the data to the next component via a Row connection.

Basic settings

Property type

Either Built-in or Repository.

Since version 5.6, both the Built-In mode and the Repository mode are available in any of the Talend solutions.

 

 

Built-in: No property data is stored centrally.

 

 

Repository: Select the repository file where properties are stored. The fields that follow are completed automatically using the fetched data.

 

Schema and Edit Schema

A schema is a row description, it defines the number of fields to be processed and passed on to the next component. The schema is either Built-in or stored remotely in the Repository.

Click Edit schema to make changes to the schema. If the current schema is of the Repository type, three options are available:

  • View schema: choose this option to view the schema only.

  • Change to built-in property: choose this option to change the schema to Built-in for local changes.

  • Update repository connection: choose this option to change the schema stored in the repository and decide whether to propagate the changes to all the Jobs upon completion. If you just want to propagate the changes to the current Job, you can select No upon completion and choose this schema metadata again in the [Repository Content] window.

 

 

Built-in: You create the schema and store it locally for this component only. Related topic: see Talend Studio User Guide.

 

 

Repository: The schema already exists and is stored in the Repository, hence can be reused in various projects and Job flowcharts. Related topic: see Talend Studio User Guide.

 

EDI filename

Filepath to the UN/EDIFACT message file to be processed.

 

EDI version

UN/EDIFACT version of the input file.

 

EDI type

UN/EDIFACT standard of the input file.

 

Ignore new line

Select this check box to skip carriage returns in the input file.

 

Loop query

Node of the structure tree on which the loop is based.

 

Mapping

Column: Reflects the schema as defined by the Schema type field.

XPath Query: Enter the fields to be extracted from the structured input. These fields are editable when the property type of the component is Built-In.

Get nodes: Select this check box to recuperate the content of all current nodes specified in the Xpath query list or select the check box next to specific nodes to recuperate only the content of the selected nodes. This operation is available when property type of the component is Built-In.

 

Die on error

Select this check box to stop Job execution when an error is encountered. By default, this check box is cleared, and therefore illegal rows are skipped and the process is completed for the error free rows.

Advanced settings

tStatCatcher Statistics

Select this check box to gather the Job processing metadata at a Job level as well as at each component level.

Global Variables

ERROR_MESSAGE: the error message generated by the component when an error occurs. This is an After variable and it returns a string. This variable functions only if the Die on error check box is cleared, if the component has this check box.

A Flow variable functions during the execution of a component while an After variable functions after the execution of the component.

To fill up a field or expression with a variable, press Ctrl + Space to access the variable list and choose the variable to use from it.

For further information about variables, see Talend Studio User Guide.

Usage

This component is usually linked to an output component to gather the processing result.
