Stored procedures
Converts an HTML string or an HTML buffer to an RTF string. The following operations are performed during the conversion:
  • Deletion of HTML tags
  • Conversion of HTML special characters
  • Conversion of CR characters (Carriage Return) to spaces
  • Conversion of multiple spaces to single spaces
The formatting is kept "as best as possible".
Example
MonTexteHTML is string = "<!--test-->'''''&quote;Bonjour!&quote;''"
Texte is string = HTMLVersRTF(MonTexteHTML)
// Texte vaut: "Bonjour"!

// Si le document HTML vaut:
//<HTML>
// <HEAD>
//  <TITLE>Ceci est un essai de page Web</TITLE>
//  <META http-equiv="content-type" content="text/html; charset=UTF-8">
// </HEAD>
//<BODY>
// <H2>Ceci est      une page HTML   en Français</H2>
//  <A href="http://www.pcsoft.fr">Ceci est un lien</A>
// </BODY>
//</HTML>

Texte = HTMLToRTF(MonTexteHTML)
// Texte contiendra le code RTF correspondant au texte suivant: 
// Ceci est     une page HTML   en Français.
//
// Ceci est un lien
Syntax
<Result> = HTMLToRTF(<Text in HTML format> [, <Charset used>])
<Result>: Character string
RTF text corresponding to the result of the HTML conversion. The encoding used is the one of the current character set of WINDEV or WEBDEV.
<Text in HTML format>: String or buffer
Text to convert.
<Charset used>: Optional Integer constant
Constant identifying the character set used to write the <Text in HTML format>. The current character set of WINDEV or WEBDEV is used by default (charsetCurrent constant). If any information about the character set used is found in the <Text in HTML format>, this information has priority over this parameter.
For more details on these constants, see Correspondence between languages, sub-languages, character sets and nations.
Remarks

Conversion rules

  • The HTML tags are analyzed to keep the best possible formatting in the output text (CR characters, spaces, tabs, etc.). Formatting is preserved as far as possible: bold, italics, colors, etc.
  • Do not appear in RTF output:
    • HTML tags
    • content of the "header" (information in the <HEAD> tag)
    • comments
    • control texts
    • scripts
    • SSL definitions
    • CSS styles (except "color" attributes)
  • Management of CR characters
    • 2 Carriage Returns are inserted to replace the following tags: <P>, <H1> to <H6>, <TABLE>, <UL> or <OL>
    • 1 Carriage Return is inserted to replace the following tags: <BR>, <TR>, <LI>, <DD> or <DIV>
    • 1 single Carriage Return is inserted if several identical tags (<TR>, <LI>, <DD> or <DIV>) follow one another (except for <BR> tags)
  • Management of arrays
    • A CR character is inserted for each array row (<TR> tag).
    • A tab is inserted for each array column (<TD> tag).
  • Management of special characters
    A special character is a character defined in the HTML standard. For example, a space can be written as " ". This standard is automatically used.
