/*============================================================================== HTML2XHTML Converter 1.5 ======================== Copyright (c) 2004-2006 Vyacheslav Smolin Author: ------- Vyacheslav Smolin (http://www.richarea.com, http://html2xhtml.richarea.com, re@richarea.com) About the script: ----------------- HTML2XHTML Converter (H2X) generates a well formed XHTML string from a HTML DOM object. Requirements: ------------- H2X works in MS IE 5.0 for Windows or above, in Netscape 7.1, Mozilla 1.3 or above. It should work in all Mozilla based browsers. Usage: ------ Please see description of function get_xhtml below. Demo: ----- http://html2xhtml.richarea.com/, http://www.richarea.com/demo/ License: -------- Free for non-commercial using. Please contact author for commercial licenses. ==============================================================================*/ /* ==================================================================================================================== # Date Developer Brief Description of Change and Reason for Change ==================================================================================================================== 1. 14-Mar-2007 pinhow For text inside "script" tag, change "&", "<", ">" to HTML code. So that it becomes XML text only. 2. 16-Mar-2007 pinhow Fixed bug. If the tag name starts with "/", skip it to prevent error in IE. E.g. In IE, any "" will be converted to "" which is wrong. 3. 15-Jun-2007 pinhow Fixed bug. Don't use RegExp.compile, Safari browser does not support. Assign directly in its constructor. 4. 19-Jul-2007 pinhow Changed fix_entities(text) function: Convert HTML code into HTML number instead of the reverse way. E.g. Convert "£" to "£", convert "€" to "€". =================================================================================================================== */ //add \n before opening tag var need_nl_before = '|div|p|table|tbody|tr|td|th|title|head|body|script|comment|li|meta|h1|h2|h3|h4|h5|h6|hr|ul|ol|option|link|'; //add \n after opening tag var need_nl_after = '|html|head|body|p|th|style|'; var re_comment = new RegExp("^$"); // #3 //re_comment.compile("^$"); var re_hyphen = new RegExp("-$"); // #3 //re_hyphen.compile("-$"); // Convert inner text of node to xhtml // Call: get_xhtml(node); // get_xhtml(node, lang, encoding) -- to convert whole page // other parameters are for inner usage and should be omitted // Parameters: // node - dom node to convert // lang - document lang (need it if whole page converted) // encoding - document charset (need it if whole page converted) // need_nl - if true, add \n before a tag if it is in list need_nl_before // inside_pre - if true, do not change content, as it is inside a
