Conversion type X to type C

Hi,

It sounds easy but I can't find a solution right now.I have read a pdf document into a variable of type "xstring". Now I want to use "REPLACE" on the XSTRING.

It should look like this:

DATA: v_xstring type xstring,

REPLACE ALL OCCURRENCES OF 'XXXNAME' IN

v_xstring WITH 'myname'.

Hw do I convert a readable string into its related X-type?

Thanks
