Handle special characters in xml

Hi,

  Our end users tend to copy the description text from Word documents to pdf form and submits it.

If that text contains any special characters, its getting carried to the extracted xml. In the next step, when I try to assign a task to user with template and this xml, Managers cannot able to open the form and showing the error. When I assign the xml without special characters, its running fine.

Please assist on how to handle this?

My expectation is that user should be prompted in the form when he pastes any special characters or they should be auto-corrected to null values. if that is not possible, atleast we should able to filter the xml and eliminate special characters before the form go to next stage.

Appreciate your help.

Thanks,

Krishna
