CH HTMLConvert 1.0

'CH HTMLConvert' is a software component that enables you to parse HTML strings and extract the plain text content.

'CH HTMLConvert' is freeware. You may freely use and distribute it with any commercial software. The source code of this component is also available. See your website for details: www.ch-software.de/htmlconvert

There a two versions of this component:

The .NET assembly contains the namespace chHtmlConvert which provides the class HtmlConvert.
This class has 3 overloads of the static member function ExtractPlainText: 

public static bool ExtractPlainText(string stHtml, out string stText); 

public static bool ExtractPlainText(string stHtml, out string stText, bool bPreferASCII); 

public static bool ExtractPlainText(string stHtml, out string stText, bool bPreferASCII, out string stCharset, out int nCodePage);

Parameters

stHTML

The character string to be converted.

stText

The character string that receives the output text.

bPreferASCII

Specifies whether some often used unicode characters will be translated to similar ASCII characters, or not. See table below: 

Unicode character

ASCII character
‑  8209   -  45
–  8211   -  45
—  8212   -  45
’  8217   '  39
“  8220   "  34
”  8221   "  34
•  8226   *  42

stCharset

The character string receiving the charset that has been specified in the HTML input.

nCodePage

The integer variable that receives the codepage number of the HTML input. For example, if the HTML input specifies the charset "Windows-1252" the codepage number will be 1252.


Return Values

If the function succeeds, the return value is true.

The return value is false if the required codepage is not installed on the system. Therefore the input text can not be converted to the correct unicode representation. The output text is unlikely to contain any readable characters.
