hi out there i need this entry to be valid inside a web.config xml file

<add key= "oledbcon" value= "User ID=;DSN=;Collating Sequence=MACHINE;Data Source="D:\PUBLIC\SOE\";Provider="VFPOLEDB.1";Cach e Authentication=False;Mask Password=False;persist security info=False;Mode=Share Deny None;Extended Properties=;Encrypt Password=False"></add>

aparently i need to escape the :, \, if any other i don't know. the question is how can i escape them? and Is there any other character to be escaped?
thanks in advance...
