How can I remove a word from string?
I have a string which contains words with parentheses. I need to remove the whole word 开发者_Python百科from the string.
For example: for the input, "car wheels_(four) klaxon"
the result should be, "car klaxon"
.
Can someone give me an example that would accomplish this?
You can do this with regular expressions. The regular expression you need is:
"\s?\S+[()]\S+\s?"
This removes any word containing either ( or ) or both, and removes both the word and collapses the surrounding whitespace. The match should be replaced with a single space.
In C# the regular expression could be used like this:
string s = "car wheels_(four) klaxon";
s = Regex.Replace(s, @"\s?\S*[()]\S*\s?", " ");
I'm not entirely sure of the VB translation for this, but hopefully you can figure it out.
Slightly different:
sed "s/\s\+\S*(.\+)\S*\s\+/ /g" yourfile
It works like this:
yourfile:
car wheels_(four) klaxon
ciao (wheel) hey
foo bar (baz) qux
stack overflow_(rulez)_the world
transformed in:
car klaxon
ciao hey
foo bar qux
stack world
If speed isn't an issue and you want to avoid overcomplicated regular expressions, you can use String.Split on " " to create an array of "words", iterate through each word, replace any that String.Contains "(" with an empty string, then use String.Join with a separator of "" to get your results.
Sorry can't send the codez, don't have a VB.NET compiler on hand.
