XML request and response

[IBJaved]

I am the beginner in this technology and its been 8 hours straight and i am not able to figure out the issue, the first thing i am not understanding is about first 3 tags,

soapenv:Envelope
soapenv:Header
soapenv:Body

the request which is generated by C# does not include "soapenv:"
More over the exception "Data at the root level is invalid".
I have tried the other way, directly passing the static data by XML and got the response which means that my credentials and server is working fine. But now i have to pass values dynamically, so gotta use C# way. Any help will be appreciated and I shall be really grateful. Its getting pain in the a** -_-


Thanks in advance.


The XML request is

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns="http://www.juniper.es/webservice/2007/">
<soapenv:Header/> 
<soapenv:Body> 
<HotelAvail> 
<HotelAvailRQ Version="1.1" Language="en"> <Login Email="[e-mail]" Password="pass" /> 
<Paxes> 
<Pax IdPax="1"> 
<Age>50</Age>
 </Pax> 
</Paxes> 
<HotelRequest>
<SearchSegmentsHotels> 
<SearchSegmentHotels Start="2013-08-20" End="2013-08-22" DestinationZone="1953"/> <CountryOfResidence>ES</CountryOfResidence> 
<Boards> 
<Board Type="AD"/> 
</Boards> 
</SearchSegmentsHotels> 
<RelPaxesDist>
 <RelPaxDist> 
<RelPaxes> 
<RelPax IdPax="1"/> 
</RelPaxes> 
</RelPaxDist> 
</RelPaxesDist> 
</HotelRequest> 
</HotelAvailRQ> 
</HotelAvail> 
</soapenv:Body> 
</soapenv:Envelope>

in C# i made like this:

XmlDocument XMLDoc1 = new XmlDocument();
