I have a string in Scala. I am trying to find all occurrences of a certain tag and find the text that is enclosed in the tag, storing the results in an array.
So for example, if my string is val string = "<p> c </p> <p> a </p> <p> t </p>"
The result I am looking for is:
val result = ["c","a","t"]
What is the best way to do this? Thanks!
Note: I am certain the tag type I am searching for will never appear nested inside another instance of itself, if that helps.
Here's a slight modification to Tony's suggestion.
val string = "<p> c </p> <p> a </p> <p> t </p>"
val re = "(?<=<p>)([^<]*)(?=</p>)".r
re.findAllMatchIn(string).map(_.toString.trim).toArray
// res0: Array[String] = Array(c, a, t)
The .trim part is optional.
The following expression will match all letters between <p> and </p>.
(?<=<p>)[^<>]*(?=<\/p>)
Your list of matches should produce the result you are looking for.
Try the following to get a list of matches:
val reg = "(?<=<p>)[^<>]*(?=<\/p>)".r
val str = "<p> c </p> <p> a </p> <p> t </p>"
val matches = reg.findAllIn(str)
while (matches.hasNext) {
val match = matches.next
}
