Split Line by Partially Known Delimiter

Question

I have a String like this:

String xml = "<Tag1>Tag One<Tag1><Tag2>Tag Two<Tag2><Fhfuehwalifhre>Bla Bla<Fhfuehwalifhre>"

I want to split this line (without knowing the names of the tags) so that I get a String array like this:

["Tag One"], ["Tag Two"], ["Bla Bla"]

Is there a way to go about doing this in a single line? (Such as xml.split("<*>");, but that does not work.) Or do I need to do it the ugly way and split it by < and > and then weed out the undesireables?

You've called your string `xml`. If it's XML, this is very brittle. What happens if elements are nested?, What if there are self closing elements? — Joshua Taylor, May 28 '14 at 17:59

Use "\<[^\>]+\>" in the split

Do `<` and `>` have to be escaped? I don't think they have any meaning in java patterns. – Piotr Praszmo May 28 '14 at 17:09
you should use \\<[^\\>]+\\> ... but it give 6 results 3 empty strings. – pL4Gu33 May 28 '14 at 17:11
Hovav and Banthar thanks guys! it works if i dont escape < and >. I can green checkmark in 5 minutes. please correct answer to exclude the \'s. Hovav – Evorlor May 28 '14 at 17:12
String[] answer = xml.split("<[^>]+>"); works, but as @pL4Gu33 says, it gives some extra empty elements. No need for any of the \'s – Evorlor May 28 '14 at 17:12
