I want to be able to match the following examples and return array of matches
given text:
some word
another 50.00
some-more 10.10 text
another word
Matches should be (word, followed by space then decimal number (Optionally followed by another word):
another 50.00
some-more 10.10 text
I have the following so far:
string pat = @"\r\n[A-Za-z ]+\d+\.\d{1,2}([A-Za-z])?";
Regex r = new Regex(pat, RegexOptions.IgnoreCase);
Match m = r.Match(input);
but it only matches first item: another 50.00
You do not account for -
with [A-Za-z ]
and only match some text after a newline.
You can use the following regex:
[\p{L}-]+\p{Zs}*\d*\.?\d{1,2}(?:\p{Zs}*[\p{L}-]+)?
See the regex demo
The [\\p{L}-]+
matches 1 or more letters and hyphens, \\p{Zs}*
matches 0 or more horizontal whitespace symbols, \\d*\\.?\\d{1,2}
matches a float number with 1 to 2 digits in the decimal part, and (?:\\p{Zs}*[\\p{L}-]+)?
matches an optional word after the number.
Here is a C# snippet matching all occurrences based on Regex.Matches
method :
var res = Regex.Matches(str, @"[\p{L}-]+\p{Zs}*\d*\.?\d{1,2}(?:\p{Zs}*[\p{L}-]+)?")
.Cast<Match>()
.Select(p => p.Value)
.ToList();
Just FYI: if you need to match whole words, you can also use word boundaries \\b
:
\b[\p{L}-]+\p{Zs}*\d*\.?\d{1,2}(?:\p{Zs}*[\p{L}-]+)?\b
And just another note: if you need to match diacritics, too, you may add \\p{M}
to the character class containing \\p{L}
:
[\p{L}\p{M}-]+\p{Zs}*\d*\.?\d{1,2}(?:\p{Zs}*[\p{L}\p{M}-]+)?\b
