Use nagios to send xml request to web service, and retrieve response

It's a bit late to see your question, but hope this helps anyway.

You can do this with the check_http plugin. The check_http Nagios plugin is shipped with the Nagios Plugins package (nagios-plugins.org)

With the -P parameter you can POST the SOAP request and with the -r parameter you can (regex) match the response for a specific string.

From the commandline using the check_http plugin:(I had to truncate you SOAP request because I coudn't post url's with http headings...)

check_http -H my.webserver.org -p 8080 -u "/testing" -P '<soapenv:Envelope .... </soapenv:Envelope>' -r 'Dublin'

If this works for you, then you need to create a new check command and service check definition in Nagios.

Example check command definition for the webservice command (using also warning and critical repsonse time values)...

define command {    command_name    check_webservice    command_line    $USER1$/check_http -H $ARG1$ -p $ARG2$ -u $ARG3$ -P $ARG4$ -r $ARG5$ -w $ARG6$ -c $ARG7$}

...and an example service check definition

define service {    use                  generic-service    host_name            my.webserver.org    service_description  check_webservice    check_command        check_http_webservice!my.webserver.org!8080!/testing!'<soapenv:Envelope .... </soapenv:Envelope>'!'Dublin'!5!10}

Please note the quoting: This is essential is these kind of checks!In the examples above I use single quotes to quote the SOAP POST request and the response.
