Find the string into an special bracket

Hello All, I have a string.

Ex: str = 'abc = "xyz";'

I want to use regexp command to find out "xyz" in below string.

my patern :

pat = '^=.;$'

with meaning (as my understanding)

_^= : beginning with =

. : get all thing between

;$ : ending with ;_

and run with

tk = regexp(str, pat) --> tk = [] in result

what wrong with my commands?

Thanks!

• ^ is the start of the string, not of the searched pattern.
• Equivalently $ is the end of the string, not the pattern, too.

What about:

regexp(str, '"(.*?)"', 'match')

or

regexp(str, '"([^"]*)"', 'match')

Thank for your answer.

I have more question.

What happen if str is not a string I input from command Window.

    I save it in file and using fopen/textscan to parse it.
    In that file with information : abc = 'xyz';

I changed "xyz" to 'xyz' and I can not parse it with your regexp command ( ' '(.*?)' ' or ' '([^']*)' ') is not available in Matlab with my test.

"Is not available"? Remember that you need two quote characters inside a string to represent quote:

str = 'This is one quote: [''] '

Run this in the command window to check it.

Parsing quotes can interfere with e.g. "it's"
