using JTidy to parse html when Div and span avalible

karyani · Dec 10, 2010

I have the bellow function after calling it the html get corrupt(notice how the </span> is moved after first line instead of at the end.). see below. help please.

public ByteArrayOutputStream convertToXHTML(String htmlString){
ByteArrayOutputStream xhtmlByteOutStream = new ByteArrayOutputStream();
if (htmlString != null && !htmlString.equals("")){
// Convert HTML to XHTML using JTidy API
Tidy tidy = new Tidy();

tidy.setXHTML(true);
tidy.setDocType("omit");
tidy.setQuoteMarks(false);
tidy.setQuoteAmpersand(false);
tidy.setQuoteNbsp(false);
tidy.setFixUri(true);
tidy.setMakeBare(true);
tidy.setJoinStyles(true);

tidy.parse(new ByteArrayInputStream(htmlString.toString().getBytes()),
xhtmlByteOutStream);
}
return xhtmlByteOutStream;

--------------------
the htmlString that is sent to the above funtion:
<html><head><title>Message Template</title><meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"/><style type="text/css">@page { size: letter; margin-top:1.0in;margin-bottom:1.0in;margin-left:1.0in;margin-right:1.0in;} body { line-height:100%;} </style></head><body><span style="font-size: 12px; font-family: Arial;"><span style="font-size: 12px; font-family: Arial;"><span style="font-size: 12px; font-family: Arial;">First line<br><div style="text-align: center;" align="center">second line<br></div>third line</span></span></span></body></html>

AFTER the call to the above function

<html xmlns="

http://www.w3.org/1999/xhtml">

<head>
<meta name="generator"
content="HTML Tidy for Java (vers. 26 Sep 2004), see

http://www.w3.org"

/>
<title>Message Template</title>
<meta http-equiv="Content-Type"
content="text/html; charset=ISO-8859-1" /><style type="text/css">
/*<![CDATA[*/
@page { size: letter; margin-top:1.0in;margin-bottom:1.0in;margin-left:1.0in;margin-right:1.0in;} body { line-height:100%;}
/*]]>*/
</style>
</head>
<body>
<span style="font-size: 12px; font-family: Arial;"><span
style="font-size: 12px; font-family: Arial;"><span
style="font-size: 12px; font-family: Arial;">First line<br />
</span></span></span>
<div style="text-align: center;" align="center">second line<br />
</div>
third line
</body>
</html>

I've never worked with JTidy, but I see most people use the parseDOM method, like here

I think JTidy has done the best guess-work. The point is that span is an "inline" element, whereas div is itself a "block" level element. An inline element could contain inline elements but not block level element even in html. Hence the original html-string passed to it is already not a properly formed html serialized string. Apparently JTidy does what it can to salvage the situation and produces the best-guessed xhtml.
