Using Groovy's Split() to grab a specific string value

Hi,

Whenever I need to parse a string to grab a specific value from within the string I use this thing that counts from the right hand side and you just specify which chars you want to grab - e.g.

def extractedStateParmValue = locationHeaderValue[-249..-205]//so above, counting from the right hand side, I'm grabbing the string between characters 205 and 249

This works fine - UNLESS the string length changes - if it does then the above doesn’t work obviously

I’ve noticed you guys using split() quote often - but typically when I’ve seen it, it’s been embedded within lots of other stuff - and I’ve never been able to unpick exactly what your code is doing.

I’ve been doing some reading and I’ve got some of it working.

Say I have the following value stored in a properties step:

Property Name = URL 

Property Value = https://whatevs.azurewebsites.net/?token=eyJ0eXAiOiJKV1Qi&value=123456789

so far I’ve got the following that grabs the value after the first = sign

//next line parses the Properties step and gets the value associated with the URL propertydef fullURL = testRunner.testCase.getTestStepByName("Properties").getPropertyValue("URL")def extractedValue = fullURL.split('=')[1] // [1] grabs the value AFTER the '=' sign, [0] would grab the value before '=' signlog.info(extractedValue)

BUT I would like to use split() to grab the value AFTER the SECOND = sign.

I also would like to be able to grab a specific value - say between the 2 ‘=’ signs

Can anyone please advise?

Cheers! (having a lot of fun with this - Iove learning new stuff :))

What is the use case?
Usually, need to have some pattern, then it would be easy.

You can run this script online

def str = 'https://whatevs.azurewebsites.net/path?token=eyJ0eXAiOiJKV1Qi&value=123456789'
def map = new URL(str).query?.split('&').collectEntries{ [(it.split('=').first()): it.split('=').last()]}
log.info map.token
log.info map.value

You can do this way also:-

def fullURL = "https://whatevs.azurewebsites.net/?token=eyJ0eXAiOiJKV1Qi&value=123456789";
String[] val = fullURL.split('&')
    for (String exp : val) {
        log.info exp.split('=')[1]
    }

It’s just a suggestion. But nmrao solution would be the best approach to use proper groovy and coding standards.
