XHTML: inline JS code produce validation errors

I have TinyMCE installed and if i go to the "edit" page i get the following errors with SGML parser. This is caused by invalid chars inside document.write

line 253 column 50 - Error: document type does not allow element "div" here
line 256 column 24 - Error: document type does not allow element "div" here
line 256 column 33 - Error: an attribute value must be a literal unless it contains only name characters
line 256 column 69 - Error: an attribute specification must start with a name or name token
line 301 column 50 - Error: document type does not allow element "div" here
line 304 column 24 - Error: document type does not allow element "div" here
line 304 column 33 - Error: an attribute value must be a literal unless it contains only name characters
line 304 column 86 - Error: an attribute specification must start with a name or name token
