Getting error while parsing xml in XE4

[rabirabi]

Hi,
I am using this as only a sample. In the real world I hava xml in string which is something like this:

Code:

IdHttp1.Post('http://MyAPIurl', Params, PostResponseinXML);

where,

Code:

Params is the stringlist containing parameters to send to the server,
PostResponseinXML is the StringStream received successfully after post.

while parsing this XMl I am getting error.
