STRICT

public static boolean STRICT

Strict parsing of CDATA flag. If this flag is set true, the parsing of script is performed without regard to quotes. This means that erroneous script such as:

 document.write("</script>");
 

will be parsed in strict accordance with appendix B.3.2 Specifying non-HTML data of the HTML 4.01 Specification and hence will be split into two or more nodes. Correct javascript would escape the ETAGO:

 document.write("<\/script>");
 

If true, CDATA parsing will stop at the first ETAGO ("</") no matter whether it is quoted or not. If false, balanced quotes (either single or double) will shield an ETAGO. Beacuse of the possibility of quotes within single or multiline comments, these are also parsed. In most cases, users prefer non-strict handling since there is so much broken script out in the wild.
