Hello,
I’ve a single .html file that contains a combination/mixture of HTML, JavaScript, and CSS codes. There are too many codes and it will take a lot of time and effort to separate html codes from javascipt codes and convert both of them. I tried many online tools but they fail to convert the combination of html and javascript to xml. Most of the time, syntax errors occurs or significant bugs in the javascript.
I tried to build my own tool to convert them but it doesn’t work properly 
I wonna convert it because I would like to use those codes on blogger.
Any ideas? Thank you so much,
