public static String truncate(String fragmentHtml,
                              int maxTextLength)

Truncate the specified HTML fragment to the maximum text length specified.

Important remark regarding behavior :
Specified HTML fragment is parsed using an HTML parser, thus when the HTML is rewritten it WILL be modified according to default output rule of the parser. Therefore line break, indentation and other whitespace may be lost during the process, but the output should not be changed as seen from the web browser.

Parameters:

fragmentHtml - the HTML fragment to truncate

maxTextLength - the maximum length of text to keep (does not include HTML tag, comment and attribute length)

Returns:

the cleaned and truncated HTML, never return null (return empty string if null was specified in input)

Important remark regarding behavior :
Specified HTML fragment is parsed using an HTML parser, thus when the HTML is rewritten it WILL be modified according to default output rule of the parser.
