regex Action
Syntax
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 isfit://request/content
)out="..."

)
<regex pattern="#abc$#" replace="123" />
<regex in="$test" out="$test" pattern="/foo/i" replace="bar" />
Usage
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.
Example
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"/>
Errors
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.
