'web service consumer soap fault extraction

I am using web service consumer and calling a soap service and it will return below soap fault incase of number of hits reaches more than the limit. When the soap fault is caught in the error handler under the type WSC:SOAP_FUALT, I want to read the faultstring and if it is "Maximum request limit reached, please try again later.", I dont want to consider it as failure and point the payload for retry.

So please let me know how to extract the fault string inorder to put a check on it.

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<soapenv:Body>
    <soapenv:Fault>
        <faultcode>Internal Server Error</faultcode>
        <faultstring>Maximum request limit reached, please try again later.</faultstring>
    </soapenv:Fault>
</soapenv:Body>

</soapenv:Envelope>

The soap fault message returned by Web Service Consumer is stored within the errorMessage field in the error of the flow. So you can use error.errorMessage.payload.Envelope.Body.Fault.faultstring to access that string in your error handler block, and use it in the when condition of the error handler itself to execute that handler when this message matches the required criteria. For example:

enter image description here

XML Code:

<on-error-continue enableNotifications="true"
    logException="true" doc:name="On Error Continue"
    doc:id="38283c80-4c20-46da-85e3-f47d5d5755b7" type="WSC:SOAP_FUALT"
    when="#[(error.errorMessage.payload.Envelope.Body.Fault.faultstring default '') startsWith ('Maximum request limit reached')]">
    <logger message="Error message caught by the error handler: #[error.errorMessage.payload.Envelope.Body.Fault.faultstring]" level="INFO" doc:name="Logger" doc:id="1f329e43-d401-412f-9479-f58bef4089c4" />
</on-error-continue>

You can use a simple DataWeave expression to extract the string:

%dw 2.0
output application/java
---
payload.Envelope.Body.Fault.faultstring

Output:

Maximum request limit reached, please try again later.
