Parameters for {exp:low_replace} tag pair

Parameter	Description
case	When set to yes, the plugin performs a case sensitive find and replace.
find	Text or pattern to replace. Required.
flags	Additional pattern modifiers, use in combination with regex="yes". Use the case parameter instead of the i flag.
multiple	When set to yes, you can use a | to define multiple values in both the find and replace parameters.
regex	When set to yes, you can use a regular expression in the find parameter, and use callbacks in the replace parameter. When set to raw, you can use a full regular expression pattern, including delimiters and flags. The case and flags parameters are ignored.
replace	Replacement text. Defaults to an empty string.

Usage notes

ExpressionEngine strips the white space from the beginning and the end of each parameter. Because of this, if you want to replace something with a space, use the string SPACE instead. You can also use the string QUOTE for a double quote, PIPE for a | and NEWLINE to match new lines.

When using regex="yes", it is recommended that you set your Debug Preference to 1, so Super Admins can make sure their regular expressions aren’t generating server errors.
