How do I make JTIdy make HTML documents well-formed?

Question

I'm using JTidy v. r938. I'm using this code to attempt to clean up a page …

final Tidy tidy = new Tidy();
tidy.setQuiet(false);
tidy.setShowWarnings(true);
tidy.setShowErrors(0);
tidy.setMakeClean(true);
Document document = tidy.parseDOM(conn.getInputStream(), null);

But when I parse this URL -- http://www.chicagoreader.com/chicago/EventSearch?narrowByDate=This+Week&eventCategory=93922&keywords=&page=1, things aren't getting cleaned up. For example, the META tags on the page, like

<META http-equiv="Content-Type" content="text/html; charset=UTF-8">

remain as

<META http-equiv="Content-Type" content="text/html; charset=UTF-8">

instead of having a "</META>" tag or appearing as "<META http-equiv="Content-Type" content="text/html; charset=UTF-8"/>". I confirm this by outputting the resulting JTidy org.w3c.dom.Document as a String.

What can I do to make JTidy truly clean up the page -- i.e. make it well-formed? I realize there are other tools out there, but this question specifically relates to using JTIdy.

Answer 1

You need specify several flags to Tidy if you want XML format

private String cleanData(String data) throws UnsupportedEncodingException {
    Tidy tidy = new Tidy();
    tidy.setInputEncoding("UTF-8");
    tidy.setOutputEncoding("UTF-8");
    tidy.setWraplen(Integer.MAX_VALUE);
    tidy.setPrintBodyOnly(true);
    tidy.setXmlOut(true);
    tidy.setSmartIndent(true);
    ByteArrayInputStream inputStream = new ByteArrayInputStream(data.getBytes("UTF-8"));
    ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
    tidy.parseDOM(inputStream, outputStream);
    return outputStream.toString("UTF-8");
}

Or simply if want XHTML form

Tidy tidy = new Tidy();
tidy.setXHTML(true);

use tidy.setXmlTags(true); to parse XML instead of HTML
