Feed Syntax: Common Methods and Regular Expressions

This method joins the items in the list into a single string. This method should follow the format below where the value in parentheses is added between each list item being joined:

{ items = []
items.1 = attr.Bullet_1
items.2 = attr.Bullet_2 }
{ items.join('</li> <li>') }

The sample above provides the following output:

Womens Shoes > Boots > Knee-High

This method returns the specified text in lowercase.

{ product.title = The Wonderful World of Parks and Recreation }
{ product.title.lower }

The sample above provides the following output:

the wonderful world of parks and recreation

This method outputs the string with all instances of the pattern--specified in the parentheses--removed. The pattern used must be a regular expression (for more on regular expressions, jump to the Common Regular Expressions section). The sample below uses the regular expression \W+ to remove one or more non-word characters:

{ name = Barry, Barry & Sons }
{ name.remove('\W+') }

The sample above provides the following output:

BarryBarrySons

This method outputs the string by searching for a pattern and replacing it with the specified text. The pattern used must be a regular expression. This method should follow the format below where the first value in parentheses is the pattern being searched for and the second value is what's replacing the pattern. The sample below uses the regular expression \W+ to replace one or more non-word characters with underscores:

{ name = Barry, Barry & Sons }
{ name.replace('\W+', '_') }

The sample above provides the following output:

Barry_Barry_Sons

This method returns the text with any leading and trailing whitespace removed.

{ text = '  Spaces: The Final Frontier        ' }
{ text.trim }

The sample above provides the following output:

Spaces: The Final Frontier
