I am trying to extract express route named parameters with regex.
So, for example:
www.test.com/something/:var/else/:var2
I am trying with this regex:
.*\/?([:]+\w+)+
but I am getting only last matched group.
Does anyone knows how to match both :var and :var2.
The first problem is that .* is greedy, and will therefore bypass all matches until the final one is found. This means that the first :var is bypassed.
However, as you are searching for a variable number of capture groups (with thanks to @MichaelTang), I recommend using two regexes in sequence. First, use
^(?:.*?\/?\:\w+)+$
to detect which lines contain colon-elements...
...and then search that line repeatedly for, simply
\/:(\w+)
This places the text post-colon into capture group one.
> var res = 'www.test.com/something/:var/else/:var2'.match(/.*?\/?([:]+\w+)+/); in node.js, I am getting only one group, not both :/.
:var and also :var2? And is the format of every line exactly the same? Meaning always two colon-elements? Never three or one? Some more realistic and more examples input and expected output would be most helpful, if you want better answers.
new Regex(str) based on the number of : chars in your path?Here is how you can match both of them:
www.test.com/something/:var/else/:var2'.match(/\:(\w+)/g)
[":var", ":var2"]
