wwUtils::Extract

Extracts a text value between two delimiters. You can specify two ending delimiters or let the end of a line be considered an ending delimiter.

You can also optionally retrieve the string with its delimiters.

Visual FoxPro 9.0 STREXTACT

Visual FoxPro 9.0 includes a STREXTRACT function that provides similar functionality and should be used whenever possible as it's native and faster. STREXTRACT was introduced in VFP 9 based on this Extract function but behavior is slightly different. Extract calls STREXTRACT whenever possible.

Use this function over STREXTRACT if you need to have a 3rd alternate ending delimiter, or you optionally need to search to the end of the string without matching a delimiter.
