Groovy & SoapUI - NumberFormatException - groovy

Question

In SoapUI I am able to get a response from a web service that gives me a string return.
XML Node Value
soap:Envelope {Envelope}
soap:Body {Body}
EuroConvertorResponse
EuroConvertorResult 1.0966 {xsd:string}
I manage to read the response in Groovy script but I get number format exception. My code is:
String conversionString = context.expand(
'${EuroConvertorRequest#Response#declare namespace
ns1=\'http://tempuri.org/\'; //ns1:EuroConvertorResponse[1]}' )
double convertedRate = Double.parseDouble(conversionString);
The exact error I get is:
java.lang.NumberFormatException: For input string: " 1.0966 " error at line: 10.
If I hard code the response like below it works fine though!
String conversionRate = "1.0966";
double convertedRate = Double.parseDouble(conversionString);
Any idea?

You are using incorrect xpath, I believe. Supposed to query for EuroConvertorResult, not EuroConvertorResponse.
Try changing from:
String conversionString = context.expand('${EuroConvertorRequest#Response#declare namespace ns1=\'http://tempuri.org/\'; //ns1:EuroConvertorResponse[1]}' )
To:
String conversionString = context.expand('${EuroConvertorRequest#Response#declare namespace ns1=\'http://tempuri.org/\'; //ns1:EuroConvertorResult}' )
Or in fact, get the double value in single line itself by coercing as below, by adding as Double at the end:
def conversionResult = context.expand('${EuroConvertorRequest#Response#declare namespace ns1=\'http://tempuri.org/\'; //ns1:EuroConvertorResult}' ) as Double
assert conversionResult instanceof Double
Alternatively, you can use XmlSlurper to achieve the same:
def result = new XmlSlurper().parseText(context.expand('${EuroConvertorRequest#Response}').'**'.find{it.name() == 'EuroConvertorResult'}.text() as Double
log.info result
assert result instanceof Double
