MidX (Function)

Format

Description

Returns the first substring that was matched by the regular expression. If the expression does not match anything the empty string “” will be returned. You may also specify an optional starting location for the search to begin start_expression.

Note

String indices begin at 1.

Example

print midx("HeLLo", "[Ll]o")
print midx("Hello, Kitti","[Ii]",10)

will display

Lo
i

Notes

By default the nature of regular expressions is “greedy”. This behaviour can be changed using the RegexMinimal statement.
