[xml] Special chars in XML

[samaram s <samaram007 gmail com>]

hi,

I am working with libxml2 library for one of my application.
But in my data there are few strings which has some special characters  like ('&' , < , >) etc
When i was reading about this...i read there is something called DTD in xml2 can handle this stuff.
But i am not getting how to use it.
Is there anyway i can make sure the xml library can handle these special chars.

Please help me in solving this.

Thanks,
Sam
