# Regular Expression Replace Template Format

Note that in addition to the standard metacharacters described in the table, Yate supports \V# and \<named variable> sequences via a prescan to insert the contents of a Variable or named variable. The inserted contents can be treated as literal characters or can be escaped to ensure that they do not interfere with any of the standard sequences.

The replacement text may contain references to capture-group text from the find. References are of the form $n, where n is the number of the capture group.

Character | Descriptions
--- | ---
$n | The text of capture group n will be substituted for $n. n must be >= 0 and not greater than the number of capture groups. A $ not followed by a digit has no special meaning, and will appear in the substitution text as itself, a $.
\ | Treat the following character as a literal, suppressing any special meaning. Backslash escaping in substitution text is only required for '$' and '\', but may be used on any other character without bad effects.
