Technical References - [regex]

[regex] is a full implementation of grep

[regex] is a full implementation of grep, starting from version 8.1 of WebDNA. The older implementation of [grep] remains for backward compatibility for its simple search and replace capabilities, however, [regex] is a better choice.

Syntax is the same as for [grep], except that it does not have the limitations of our implementation of [grep]

Some specific operators used by [regex] will be interpreted by WebDNA, like "%2B" or "%26" for instance. In this case, it is safer to [url][/url] the operator like in the following



Example:
[text]value=\b0%2B[/text]
[regex search=[value]&replace=]080.010.001.305[/regex]


or
[text]value=\b0+[/text]
[regex search=[url][value][/url]&replace=]080.010.001.305[/regex]


will both show 80.10.1.305
