How to parse delimited data

The data in a URI that is delimited into segments can be parsed. TDelimitedXxxxParser8 classes provide the functionality to parse delimited data, extract the current segment and parse the string for the next segment.

• TDelimitedXxxxParser8 provides the following functionality:

  Set the delimiter to a specific character using SetDelimiter().

  SetDelimiter(TChar('/')); //set the delimiter character to '/'

  Note: Set the delimiter before you parse the data.

• Parse the data into segments from left to right using Parse().

• Parse the data into segments from right to left using ParseReverse().

Parse the data into segments before calling any of the following functions.

• Parse to the next segment using Inc().

• Get the descriptor reference with the data using Des().

• Get the current segment and parse the data to the next segment using GetNext().

• Get the current segment using Peek().

• Get the remaining data from (and including) the current segment using Remainder().

To use the above functions, you need to use the class derived from TDelimitedParserBase8.

The following three classes are used to parse the respective URI components:

1. TDelimitedPathParser8 for parsing path into directories seperated by '/'.

   For example:

   /doc_source/guide/N10047/index.html

2. TDelimitedPathSegmentParser8 for parsing parameters that are separated by ';'

   For example:

   postd=pp22;[email protected];user=phone

3. TDelimitedQueryParser8 for parsing the query string (after a '?') into name/value pairs that is separated by '&'.

   For example:

   sortcol=4&table=1&up=0&view=details

   The table shows the delimiter to be used to seperate each of the URI components.
