The HTF (hypertext functions) and HTP (hypertext procedures) packages generate HTML tags. For example, the HTF.ANCHOR function generates the HTML anchor tag, <A>.

Operational Notes
Rules and Limits
Examples
For every HTF function that generates one or more HTML tags, there is a corresponding HTP procedure with identical parameters with the following exception:
The PRINTS Procedure and the PS Procedure do not have HTF function equivalents. Use the ESCAPE_SC Function or the ESCAPE_URL Function if you need a string conversion function. Note that while there is a ESCAPE_SC Procedure that performs the same operation as the PRINTS Procedure and the PS Procedure, there is no procedural equivalent for the ESCAPE_URL Function.
The FORMAT_CELL Function does not have an HTP equivalent. The function formats column values inside an HTML table using TABLEDATA Function which does have an HTP equivalent in the TABLEDATA Procedure. The advantage of this using the FORMAT_CELL Function is that it allows for better control over the HTML tables.
The function versions do not directly generate output in your web page. Instead, they pass their output as return values to the statements that invoked them. Use these functions when you need to nest calls. To print the output of HTF functions, call the functions from within the HTF.PRINT function. It then prints its parameters to the generated web page.
If you use values of the LONG data type in functions such as HTF.PRINT, HTF.PRN, HTF.PA or OWA_UTIL.CELLSPRINT, only the first 32 K of the LONG data is used. The LONG data is bound to a VARCHAR2 data type in the function.
The following commands generate a simple HTML document:
CREATE OR REPLACE PROCEDURE hello AS
BEGIN
HTP.P (HTF.HTMLOPEN); -- generates <HTML>
HTP.P (HTF.HEADOPEN); -- generates <HEAD>
HTP.P (HTF.TITLE('Hello')); -- generates <TITLE>Hello</TITLE>
HTP.P (HTF.HEADCLOSE); -- generates </HEAD>
HTP.P (HTF.BODYOPEN); -- generates <BODY>
HTP.P (HTF.HEADER(1, 'Hello')); -- generates <H1>Hello</H1>
HTP.P (HTF.BODYCLOSE); -- generates </BODY>
HTP.P (HTF.HTMLCLOSE); -- generates </HTML>
