Pattern replace token filter
editPattern replace token filter
editThe pattern_replace
token filter allows to easily handle string
replacements based on a regular expression. The regular expression is
defined using the pattern
parameter, and the replacement string can be
provided using the replacement
parameter (supporting referencing the
original text, as explained
here).
Beware of Pathological Regular Expressions
The pattern replace token filter uses Java Regular Expressions.
A badly written regular expression could run very slowly or even throw a StackOverflowError and cause the node it is running on to exit suddenly.
