The +data in the URI that is delimited into segments can be parsed using the TDelimitedXxxxParser8 classes. +

Parse the delimited data using the following functionalities +of TDelimitedXxxxParser8:

    +

  • Set the delimiter (before parsing the data) to a specific character +using SetDelimiter(). For example:

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

  • 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 functions described in the +following steps.
    • +

  • 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().

    • +

 +

TDelimitedXxxxParser8 classes provide +functionalities to parse delimited data, extract the current segment and parse +the string for the next segment.

Use the class derived from TDelimitedParserBase8 for +implementing the function provided by TDelimitedXxxxParser8.

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

+ + + +

TDelimitedPathParser8 for parsing path into directories +separated by '/'. For example: /doc_source/guide/N10047/index.html.

 + + +

TDelimitedPathSegmentParser8 for parsing parameters +that are separated by ';' For example: postd=pp22;isub=1411@foo.com;user=phone.

+ + +

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 following table shows the delimiter to be used to separate each +of the URI components:
