  I tried to accumulate the whole xml(<doc>...</doc>) as string using 
sax, but in this case all special characters are processed by parser
and are just characters and not "predefined entities" like &quot;

Using stax, I get correct xml, if I print events right away, but I if I 
store them in collection and print them later , I don't get the same result.
