Graham toshudhiman I just tested and there is the potential that the editor could convert the " quotes " to entities
so you could use

<!--parser:xtscript--> var $path=<xt:url type="path" /> <!--/parser:xtscript-->

in the _header _footer or _headtags and {_$$path|} in existing pages title setting and the site option setting for new pages Or if you already have loads of pages then you could use a bit of javascript in the _header _footer or _headtags

<script type="text/javascript"> document.getElementsByTagName("title")[0].textContent='<xt:url type="path" />'; </script>

Which would do all pages Or this version which looks better because it trims off the leading / and replaces all other / with -

<script type="text/javascript"> document.getElementsByTagName("title")[0].textContent=('<xt:url type="path" />'.substr(1).replace((new RegExp('/','g')),' - ')); </script>
