sending TIBCO xmsl using sendkeys

Hi,

I am writing a VBScript to send tibco bus requests which are in xml form.
I am able to send these xmls using command prompt using the tibrvsend and tibrvlisten commands.
The same thing I want to do in QTP using VBScript i.e invoking the cmd,and then executing these commands using sendkeys method of VB.
The problem is the xml request which I have to send contain various special characters like <,>,",',:,/ etc.
How can it be possible to send such an xml as an arument to the sendkeys method.

Sendkeys can send any key or character except the PrintScreen key.
