# Remove Text Using Substrings

## Overview

This operation allows you to edit a text by specifying a piece of text ("a substring") to remove. You can optionally define the strategy to remove the substring's first, last, or all occurrences in the larger text.

## Syntax

```
the text1 is "{text1 value}"
the text2 is "{text2 value}"
remove the text2 from the text1
```

#### Optional: Specifying a Remove Strategy

Optionally, you can specify a **remove strategy** using the **where** keyword. This specifies which occurrences of the second text to remove:

```
the text1 is "{text1 value}"
the text2 is "{text2 value}"
remove the text2 from the text1 where
 the remove strategy is "{strategy}"
```

## Data

The table below lists the names of the data elements in this operation and indicates which can be renamed in the syntax.

| Data Name           | Can Be Renamed |
| ------------------- | -------------- |
| the text1           | Yes            |
| the text2           | Yes            |
