Components > Tools > Text

Description

This non visual component can be used for fast syntactical parsing of texts. On base of preliminary registered delimiters and key words together with there properties, in turn extracts from any text these elements. There are 6 statuses of element: Word, Integer, StandardNumber, ScientificNumber, KeyWord, Delimiter and custom status definition possibilities. Also is possible to use wildcards for registration of key words and delimiters.

This component is Intended for component Advanced Calculator.
