Property Transfers get sid from the CDATA

the solution was found, it is not very pretty but works

def groovyUtils = new com.eviware.soapui.support.GroovyUtils(context)
def response = context.expand('${GetSID - GetSID#ResponseAsXml}')
def holder = groovyUtils.getXmlHolder(response)
node_data = holder.getNodeValue("//data")
String str = node_data; 
//get data between the text   
String result1 = str.substring(str.indexOf("sid") + 1, str.indexOf("upgrades"));
//delete all extra symbols in the string
String result2 = result1.replaceAll('"',"")
String result3 = result2.replaceAll(":","")
String result4 = result3.replaceAll("id","")
String result = result4.replaceAll(',',"")
//set global variable
com.eviware.soapui.SoapUI.globalProperties.setPropertyValue( "sid", result )

Hey UnnounUsername 

Apologies - Ive only just seen your post.  I can see you've already sorted this out, but for future reference, there is an alternative option to relying on groovy script when attempting to extract values from CDATA wrapped xml - you can actually use the embedded functionality instead.

Essentially the short answer is to use a property within a property.

If you launch --> https://www.soapui.org/docs/functional-testing/working-with-cdata/

Navigate to section '3. Property Transfers and CDATA Sections' and follow these instructions.  I've used this option a couple of times - it's not pretty either - but it gets the job done!

Cheers,

Rich
