Dividing an one-line HTML file to well-formed HTML file

Question

I have an HTML file in which all tags are in one line. I would like to separate each tag and put it on its own line. The end goal is to have a well-formed HTML file.

e.g.

<html><head><title>StackOverflow</title></head><body></body></html>

would be converted into:

<html>
    <head>
        <title>
        StackOverflow
        </title>
    </head>
    <body>
    </body>
</html>

Is there an existing Java library that handles this already?

if you want to format your code? copy it into eclipse or any ide. and use their code formater. — Akhi, Jun 26 '12 at 12:46
but I have more than 10000 files, so I think it is impossible to do manually — Hadi, Jun 26 '12 at 12:51
Note that pretty-printing like this *can* change how it displays. Specifically if whitespace is injected where there was none before. — Joachim Sauer, Jun 26 '12 at 13:03
It just seemed like a one off thing that a scripting language could handle is all. I wanted to know if the @Hadi was open to other options before writing out an answer - Java it is. — Jay, Jun 26 '12 at 14:24

Your problem has nothing to do with well-formed HTML files. Even if html tags are on the same line, doesn't mean that the html is not well formed. What you actually neeed is just a formatter, which basically will make your html more human-readable. You could take a look at JTidy, which can optionally do also a syntax checking.
