String :: extract - Get string between begin end end tag

Implementation overview

• Get string between begin end end tag
  String :: extract ( sBegin, sEnd )
• Extract nested strings
  String :: extract ( iPosition, sBegin, sEnd, sStringSep )
• Get string between begin end end tag starting at position
  String :: extract ( iPosition, sBegin, sEnd )

Implementation details

1. Get string between begin end end tag
   odaba::String String  :: extract ( odaba::String &sBegin, odaba::String &sEnd )
   

   The function searches the string from beginning

   • sBegin - Starting or begin string
   • sEnd - Terminating or end strint
to list
2. Extract nested strings
   odaba::String String  :: extract ( int32 iPosition, odaba::String &sBegin, odaba::String &sEnd, odaba::String &sStringSep )
   

   In order to extract strings from nested text strings, string delimiters sBegin and sEnd are considered as single characters defining the begin and the end of a text block (e.g. '{' and '}'). The string separator (e.g. '"') passed in sStringSep is also considered as single character. String delimiters within strings between string separators will be ignored. Searching starts at iPosition.

   • iPosition - Position in collection

     The position of an element in a collection is beginning with 0 for the first element.

   • sBegin - Starting or begin string
   • sEnd - Terminating or end strint
   • sStringSep - - internal feature
to list
3. Get string between begin end end tag starting at position
   odaba::String String  :: extract ( int32 iPosition, odaba::String &sBegin, odaba::String &sEnd )
   

   The function starts searching at position passed in iPosition. When iPosition is less than 0, the function throws an exception.

   • iPosition - Position in collection

     The position of an element in a collection is beginning with 0 for the first element.

   • sBegin - Starting or begin string
   • sEnd - Terminating or end strint
to list
