Help List in groovy with regex

[Peter Paiva]

Olá
eu preciso fazer uma validação em uma lista de strings groovy.

a validação é, dentro da lista só pode haver strings que terminam com ".com"

se algum elemento dentro da lista não terminar com ".com" ou, vier algum elemento vazio na lista, o resultado é false

se todos os elementos dentro da lista vier com final ".com" e não tiver algum elemento vazio na lista, o resultado é true

Hello
i need to do a validation on a list of groovy strings.

the validation is, inside the list there can only be strings that end with ".com"

if any element within the list does not end with ".com" or, there is an empty element in the list, the result is false

if all elements within the list end with ".com" and there are no empty elements in the list, the result is true




example of list false:

def scopes = ["CONT.com", "", "CA.com", "TOP.br", "GUYS.cear", ".read", "com"]

example of list true:

def scopes = ["CONT.com", ".com", "CA.com", "TOP.com", "GUYS.com", ".com"]




boolean result = scopes.findAll{it.endsWith(".READ")}
def checaRead = scopes.findAll{it.endsWith(".READ")}
def vejaRead = scopes.any {".READ"}
def validaReadWithRegex = scopes.findAll { it =~ /.READ/ }
boolean  validaReadWithRegexs = scopes.findAll { it ==~ /\.READ/ } //aqui ja pesquisa com o ponto e palavra pra validar

println(result)
println(checaRead)
println(vejaRead)
println(validaReadWithRegex)
println(validaReadWithRegexs)

Peter Palva,

Welcome to Code Ranch.
I don't know the best answer.   I was wondering what would happen if you tested one item in the list at a time using regex.  If there is a blank or no .com at the end then exit with false.  I don't know the performance difference over a single correct regex expression on a list.

I have a Mastering Regular Expressions book by O'reilly on my book shelf so I looked in the index for list.   I think there is information in it around page 310 that has to do with your question.

I wish I could be more help but I saw nobody answering your post.

Thanks,

Kevin

An empty element doesn't end with ".com", so maybe you could rewrite that as

if all elements within the list end with ".com", the result is true

Which would simplify your solution, perhaps?

Paul,

Good idea.  I didn't think of it like that.

Thanks,

Kevin
