For this purpose we can use ServerVariables in the Data View Web Part. We can create new parameters from Common Data View Task as shown in the screen shot:
Give a proper name to the Parameter and then specify which Server Variable we want to access with this. Once we do this this Server Variable will be assigned to this parameter. In my case I have created two variables with SERVER_NAME and LOGON_USER
Once this is done these variable can accessed from XSLT using the code:
<xsl:value-of select="$ServerName"></xsl:value-of>
All the Server Variables list which we can use are found here:
