xml parsing - Using a variable to extract value of property of an element in groovy using xmlSlurper -

i using soapui test webservices. following string (in xml format) request:

<request>    <ac>       <assetid>1</assetid>       <asset_name>abc</asset_name>       <asset_number>1</asset_number>    </ac>    <ac>       <assetid>2</assetid>       <asset_name>xyz</asset_name>       <asset_number>2</asset_number>    </ac> </request> 

i using following code in groovy script extract value of asset_number each ac (the above xml string stored in variable strrequest):

def x = new xmlslurper().parsetext("$strrequest")  x.ac.each { ac -> assetnum = ac."asset_number" <<do assetnum>> } 

however, wish parameterize above code pick asset_number various types of assets (e.g. ac, peripheral etc). request xml each asset in same format above. if replace 'ac' variable name 'requestname' in above code:

//strrequest = xml request def requestname //i pick value test case property def x = new xmlslurper().parsetext("$strrequest")  x.(requestname.tostring()).each { requestname ->     assetnum = requestname."asset_number"     <<do assetnum>> } 

it shows following error:

org.codehaus.groovy.control.multiplecompilationerrorsexception: startup failed: script166.groovy: 35: current scope contains variable of name requestname @ line 35, column 2. { ^ org.codehaus.groovy.syntax.syntaxexception: current scope contains variable of name requestname 

i have tried solution mentioned in post using string code groovy xml parser, doesn't serve purpose.

any other ideas?

you can use

x."$requestname".each
