XSLT : Parse XML formatted data in XSLT stored in text area attribute in Quote

Summary:

I have xml formatted data stored in Quote text area type of attribute.

I would like to parse this data in Document Designer XSL template using xpath expression.

When I tried this then instead of getting information from xpath, I see whole XML in text format and I need to apply XSL substring functions to get required information.

Is there any way to convert text formatted XML data into XML tag/value format so through xpath I can fetch required information.
