I used wrong term.
I would like to escape chars. But I found different link that say
different chars that are reserved to XML.
As I know there are: <, >, & and % (4 chars).
There are additional that I must know?
I wonder what suggests to you that % is to escape...
Also, if your xml includes attributes, you may have to escape the
double quotes and/or the apostroph with " and ', otherwise
how will you insert quotes in an attribute's value?
