/* variable in which the text of the format "«text» text...." */
header = Mobile.getText(findTestObject('Object Repository/mainNews/header'), 0)

Mobile.tap(findTestObject('Object Repository/mainNews/header'), 0)
/* variable in which the text of the format "«text» other text" */
header1 = Mobile.getText(findTestObject('mainNews/h1'), 0)

Mobile.verifyMatch(header1, header, true)

Do you mean you want to extract a text enclosed by a pair of « and » character?

exactly."«(.*?)» " regular expression . but I don’t know how to apply it

See https://www.baeldung.com/groovy-pattern-matching for using Regex in Groovy.

def header = "«text» text...."
def matcher = header =~ /«(.*)»/
assert matcher.size() == 1
println matcher[0][1]

def header1 = "«TEXT» other text"
def matcher1 = header1 =~ /«(.*)»/
assert matcher.size() == 1
println matcher1[0][1]

When I ran it, I saw

I wonder if «(.*?)» is a valid regexp.

I used «(.*)» instead.

Thank you very much, this is not the first time I have used your advice from the forum. you are awesome

will this work with another regex?
example " (^.{35}) "

I don’t understand your question.

Why not you just try and see?
