Hi,<\/p>\n
In my recent grails project, i needed to check the occurrence of a word in a string. I could have used contains() method of groovy , but the problem with contains() is that it also matches the word if the word is contained as a substring in any word.
\nI searched a lot, but nothing worked out so i decided to use Regular expression for it. With the help of my colleague,we came out with a simple regex to find the occurrence of exact word in a long string, even if the word is surrounded by comma, full-stop or some other character.<\/p>\n
The regex is:-<\/p>\n
\r\n String matchingWord=\"string\" \/\/ word to find\r\n String longString=\"it is a very long string. find the exact word in it\" \r\n\r\n \/\/ method to return the result\r\n\r\n def pattern = \/\\b${matchingWord}\\b\/\r\n def matcher = longString =~ pattern\r\n return matcher.getCount() ? true : false\r\n\r\n\r\n<\/pre>\nThe method returns true if the exact word is found in the string. But it will return false if the word is occurring as substring.<\/p>\n
It worked in my case.
\nHope it helps.<\/p>\n
