search for particular text in a multi-line string
I'd like to have your suggestions on searching for particular text in a multi-line string.
I found the contains() method does not work:
boolean isContain = multi_line_String.contains(expectedText)
Do I have to break down my multi line string into single lines for the search? I think that may slow down the search.
Or is there an object I could use to declare the multi line, instead of using String?
many thanks,
Kind Regards

It seems to me that `contains()` works as expected.
def str = '''foo bar
baz quux'''
assert str.contains('bar')
assert str.contains('baz')
assert str.contains('r\nb')
assert str.contains('xxx') == false
Cheers,
Dinko

Can you give an example of what isn't working as expected? contains()
should be good enough if you have the appropriate line endings in your
expected text. Otherwise regex searching might be the way to go.
Cheers, Paul.

RE: search for particular text in a multi-line string

Contains works, but depending on your situation you might need to normalize data. If you don't know where your line breaks are, for example if you want to find "the cow jumped over the moon" but the string is "I read a book. It is called the Cow\nJumped Over the Moon", in this case you need to normalize the input. You can normalize any sequence of whitespace (including newlines) to a single space and do a case insensitive comparison (or convert everything to lower case).
