strip¶

The strip filter is designed to remove leading and trailing whitespace characters from a string. It combines the functionality of both lstrip (removing leading whitespace) and rstrip (removing trailing whitespace).

Functionality

Strings: Takes a string as input.
Stripping: Removes any whitespace characters (spaces, tabs, newlines) from both the beginning and the end of the string.
Output: Returns a new string with the leading and trailing whitespace removed.

Syntax

    {{ input_string | strip }}

Arguments

The strip filter does not require any arguments.

Code Samples

Example 1: Removing Leading and Trailing Spaces

    {% assign message = "   This string has spaces on both ends.   " %}

    {{ message | strip }}

Output:

This string has spaces on both ends.

Example 2: Removing Whitespace Around a Code Block

    {% assign code = "\t\n  def function():\n    pass  \t\n" %}

    {{ code | strip }}

Output:

def function():
pass

Outliers and Special Cases¶

Empty Strings: If the input string is empty, the strip filter returns an empty string.
Strings Without Whitespace: If the input string does not have any leading or trailing whitespace, the filter returns the original string unchanged.
Non-String Input: If the input is not a string, the strip filter might attempt to convert it to a string or return an error, depending on how Experience Builder handles type conversions.

Key Points¶

The strip filter is a convenient shortcut for removing whitespace from both ends of a string in a single operation.
It is particularly useful when normalizing text data, such as user input or data imported from external sources.
Consider using lstrip or rstrip if you need to remove whitespace from only one end of the string.
