we use log4net to produce log files, and have the json extensions for log4net so the file output is as follows

{
"date":"2016-03-18T13:49:36.9504697-04:00","level":

"ERROR",
"appname":"log4net_json.vshost.exe",
"logger":"log4net_json.Program",
"thread":"9",
"ndc":"(null)",
"message":"System.DivideByZeroException: Attempted to divide by zero.\r\n   at log4net_json.Program.Main() in c:\\temp\\tryMeOut\\log4net.Ext.J
            son.Example-master\\log4net_json\\log4net_json\\Program.cs:line 20"

}

we want to use nxlog to consume the file and post the results to a remote web api that will insert the json values into our database.  I have tried loads of variations of config changes and 
spent hours on the internet / reading the documentation with no luck.  Below is one of the config files I have used, however each time i send it out the i only get the first character of the 
the text, the "{"  .  the rest is missing and will not post

define ROOT C:\Program Files (x86)\nxlog
Moduledir %ROOT%\modules
CacheDir %ROOT%\data
Pidfile %ROOT%\data\nxlog.pid
SpoolDir %ROOT%\data
LogFile %ROOT%\data\nxlog.log
LogLevel INFO

<Extension _syslog>
    Module xm_syslog
</Extension>

<Input in>
    Module      im_file
    File "C:/temp/WOWLog.xml"
    InputType LineBased    
    SavePos     FALSE  
    ReadFromLast FALSE
    
    Exec    if $raw_event =~ /^--/ drop();
    Exec    $raw_event = replace($raw_event, "\r\n", ";");
</Input>

<Output out>
  Module              om_http
  URL                 http://localhost:51990/api/LogFile/
# HTTPSAllowUntrusted TRUE
</Output>

<Route 1>
    Path        in => out      
</Route>

Looking for the correct settings for the configuration file.  
for sanity I have been able to send the same file to the remote web api via a .net console application with a web client
