ABENSTRING_FUNCTIONS_REGEX_OBS - STRING FUNCTIONS REGEX OBS

- regex (Obsolete)

... ( ... regex = posix ...  ) ...

Effect

In string functions, where the arguments pcre or xpath can be used, the argument regex is also possible. posix is then a character-like expression position that must contain a POSIX regular expression.

Note

Example

The result of the following function call is tag>def</tag>. The POSIX regular expression is greedy and special care must be taken to find the desired substring between the tags.
