syntaxhighlighter_3.0.83: theme_tests.html(A DOCTYPE is not allowed in content)


I am getting an error on theme_tests.html page provided with syntaxhighlighter_3.0.83, which I wasn't getting earlier. The error is A DOCTYPE is not allowed in content at <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> inside first script tag <script id="sample" type="text/plain"> tag.

Here is the page theme_tests.html:

The web page page I have in my java web application is rendering alright in chrome but not on firefox 4. I remember the same page in my application used to work alright on both browsers before.

Only changed I have done to my system ever since I saw my application rendering the same page properly are:

  1. I added jquerywtp1.10 plugin to my eclipse 3.5 IDE.

  2. Updated firefox to firefox 4 version.

Could someone help me understand what should I do to get the same web page properly displayed on mozilla firefox 4 as well?

This is where I am getting the error, on line number 29: http://programatori.evonet.ro/images/1308360109285/doctype.jpg

theme_tests.html is could be found at: https://bitbucket.org/alexg/syntaxhighlighter/src/a8771a7fc81d/tests/theme_tests.html

Could someone enlighten me for how to do away with this error?


Solution

  • You have declared the document to be a XHTML strict document. However, the document structure violates the doctype rules. Nesting another <!DOCTYPE in the document is illegal. Also putting the JS code with unescaped XML entities in a XHTML strict document is illegal. Learn about doctypes at http://hsivonen.iki.fi/doctype and validate your document against the http://validator.w3.org.

    Your first step is to wrap that nested XHTML document in a <![CDATA[ block and move all that JS out into its own .js file. Also, having the <style> without type attribute outside the <head> is illegal.

    This problem has nothing to do with JSP. It's just basic (X)HTML knowledge.
