rtf文本格式如何转换html格式(c#代码实现),第1张

将RTF格式的文件转成HTML并在网页中显示的代码它是这样工作的，将一个RTF文件上传，然后转成HTML显示出来，代码有点复杂,teaman还要好好研究,好象中文版有点问题。 <html><body><? if(!($userfile)) { ?><form enctype="multipart/form-data" action="<?print($PHP_SELF)?>" method=post><input type=hidden name="max_file_size" value=2000>Send this file: <input name=userfile type=file><input type=submit value=Upload></form></body></html><? exit} function ProcessTags($tags, $line) { $html = ""global $colorglobal $sizeglobal $bullets// Remove spaces. $tags = trim($tags)// Found the beginning of the bulleted l // ist. if(ereg("\\\pnindent", $tags)) { $html .= "<ul><li>"$bullets += $line$tags = ereg_replace("\\\par", "", $tags)$tags = ereg_replace("\\\(tab)", "", $tags)} if($line - $bullets == 0) { $tags = ereg_replace("\\\par", "", $tags)} elseif($line - $bullets == 1) { if(ereg("\\\pntext", $tags)) { $html .= "<li>"$tags = ereg_replace("\\\par", "", $tags)$tags = ereg_replace("\\\(tab)", "", $tags)$bullets++} else { $html .= "</ul>"$bullets = 0} } // Convert Bold. if(ereg("\\\b0", $tags)){ $html .= "</b>"} elseif(ereg("\\\b", $tags)) { $html .= "<b>"} // Convert Italic. if(ereg("\\\i0", $tags)){ $html .= "</i>"} elseif(ereg("\\\i", $tags)) { $html .= "<i>"} // Convert Underline. if(ereg("\\\ulnone", $tags)){ $html .= "</u>"} elseif(ereg("\\\ul", $tags)){ $html .= "<u>"} // Convert Alignments. if(ereg("\\\pard\\\qc", $tags)) { $html .= "<div align=center>"} elseif(ereg("\\\pard\\\qr", $tags)) { $html .= "<div align=right>"} elseif(ereg("\\\pard", $tags)){ $html .= "<div align=left>"} // Remove \pard from the tags so it does // n't get confused with \par. $tags = ereg_replace("\\\pard", "", $tags)// Convert line breaks. if(ereg("\\\par", $tags)){ $html .= "<br>"} // Use the color table to capture the fo // nt color changes. if(ereg("\\\cf[0-9]", $tags)) { global $fcolor$numcolors = count($fcolor)for($i = 0$i <$numcolors$i++) { $test = "\\\cf" .

不行的话试试这个
