regex Action # ⚠️ Deprecated: → use the
replace()function instead
Attributes:
pattern="..." to define the search expression including delimiter and modifier (required)replace="..." to set the replacement text (required)in="..." to define the input location (optional, default is fit://request/content)out="..." to define the output location (optional, default is fit://request/content)<regex pattern="#abc$#" replace="123" />
<regex in="$test" out="$test" pattern="/foo/i" replace="bar" />
The regex action works on text content only. However, if the input is a DOM, it is
automatically serialized into a string for the action to work.
The output of this action is always a string.
The replacement is carried out with the PCRE regular expression library.
This example converts a date of the form YYYY-MM-DD into DD.MM.YY:
<regex pattern="|20([012]\d)-(\d\d)-(\d\d)|" replace="$3.$2.$1"/>
If the pattern does not compile, the request will terminate with an error.
It is not an error if the pattern does not match or the replacement is empty.
