How to sent information via input txt file in SOAP UI POST request

Hi,

This is my first post in the community hope i will get some solution.

I have a network product which provides us the REST API to get/create/modify different services but according the vendor document while creating a service there are number of parameters we need to sent in the curl request as input file.

Here is the sample curl request based on their document:

curl -X POST –u jsmith:password –d @input.txt -k https://192.0.2.1:8443/ng1api/ncm/services -H “Content-Type:application/xml”

Now my question how can i run the POST request with the input.txt using the SOAP UI .

I have a input in XML (contents of input.txt)

<services>

    <serviceDetail>

        <serviceType>1</serviceType>

        <alertProfileID>1</alertProfileID>

        <isAlarmEnabled>false</isAlarmEnabled>

        <serviceMembers>

             <enableAlert>false</enableAlert>

             <locationKeyInfo>

                 <isLocationKey>true</isLocationKey>

                 <keyType>10</keyType>

                 <keyAttr>0</keyAttr>

                 <asi1xType>VLAN</asi1xType>

             </locationKeyInfo>

             <protocolOrGroupCode>POP2</protocolOrGroupCode>

             <meAlias>myProbe:if4</meAlias>
        </serviceMembers>

      <id>-1</id>

      <serviceName>testApp1</serviceName>

    </serviceDetail>

</services>

Thanks
