Property Transfer Conditional

Toananas 

For the first request (where you get the response and need to extract the data), add a script assertion with following snippet

assert context.response, 'Response is empty or null'
//Get DefCategoriesDispo first match with StatutDispo is true
def catDispo = new XmlSlurper().parseText(context.response).'**'.find {it.name() == 'DefCategoriesDispo' && it.StatutDispo == true}

//Extract data and save them into custom properties
context.testCase.setPropertyValue('CATID', catDispo.CatId.text())
context.testCase.setPropertyValue('CATCODE', catDispo.CatCode.text())

In the next step where ever CatId, CatCode are needed

use ${#TestCase#CATID}, ${#TestCase#CATCODE} respectively

You can apply the same logic to the rest of the fields.

Say for eg:

<hit:Categ>${#TestCase#CATID}</hit:Categ>
