Preserving Portions of the Original Text

Preserving Portions of the Original Text

In the
exp
property, you can enclose portions of the regular expression in parentheses. In the
replacement
property, you can use:
  • $0
    to identify the entire text that matches the regular expression
  • $1
    to identify the substring that matches the first parenthesized portion of the regular expression
  • $2
    ,
    $3
    , and so forth, to identify the substrings that match the second, third, etc. parenthesized portions
For example, suppose you set:
exp = abc([0-9]+)(def) replacement = $1
This replaces
abc5624def
with
5624
.
Alternatively, suppose you set:
exp = abc([0-9]+)(def) replacement = $2ZYX$1
This replaces
abc5624def
with
defZYX5624
.
