# tExtractRegexFields Standard properties These properties are used to configure tExtractRegexFields running in the Standard Job framework. The Standard tExtractRegexFields component belongs to the Data Quality and the Processing families. The component in this framework is available in all Talend products. ## Basic settings | Properties | Description | | --- | --- | | Field to split | Select an incoming field from the Field to
split list to split. | | Regex | Enter a regular expression according to the programming language
you are using. | | Schema and Edit
Schema |

A schema is a row description. It defines the number of fields (columns) to be processed and passed on to the next component. When you create a Spark Job, avoid the reserved word line when naming the fields.

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.
Click Sync columns to retrieve the schema from the previous component connected in the Job.

Information noteWarning:
Make sure that the output schema does not contain any column with the same name as the input column to be split. Otherwise, the regular expression will not work as expected.
Built-In: You create and store the schema locally for this component only.
Repository: You have already created the schema and stored it in the Repository. You can reuse it in various projects and Job designs.

| ## Advanced settings | Properties | Description | | --- | --- | | Die on error | Select the checkbox to stop the execution of the Job when an error
occurs.

Clear the checkbox to skip any rows on error and complete the process for
error-free rows. When errors are skipped, you can collect the rows on error using a Row > Reject link. | | Check each row structure against
schema | Select this check box to check whether the total number of columns
in each row is consistent with the schema. If not consistent, an
error message will be displayed on the console. | | tStatCatcher Statistics | Select this check box to gather the processing metadata at the Job
level as well as at each component level. | ## Global Variables | Variables | Description | | --- | --- | | 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 checkbox is
cleared, if the component has this checkbox.

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 more information about variables, see [Using contexts and variables](https://help.qlik.com/talend/r/en-US/8.0/studio-user-guide/contexts-and-variables). | ## Usage | Usage guidance | Description | | --- | --- | | **Usage rule** | This component handles flow of data therefore it requires input
and output components. It allows you to extract data from a
delimited field, using a Row >
Main link, and enables you to
create a reject flow filtering data which type does not match the
defined type. |
