the best solution

Hi everybody,
the processing and validation of an xml document on the server side in an
assembly line is really interesting (i mean something like: 

xm document->Schema w3c validation->Schematron validation->databinding to
java...)

the problem is: if i want to check for validation just behind the browser
where i write my xml document, i don't find any other way than doing using
javascript...

so is there anyway to check for validation in the browser using Schema W3C
and Schematron before sending the xml to the server?

i will be really thankful for anyanswer because i need it a lot..
thank you..
